     BACKGROUND 
     Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. 
     Vehicles, such as automobiles, light-duty trucks, and heavy-duty trucks, play an important role in the lives of many people. To keep vehicles operational, some of those people rely on vehicle technicians to diagnose and repair their vehicle. 
     Vehicle technicians use a variety of tools in order to diagnose and/or repair vehicles. Those tools may include common hand tools, such as wrenches, hammers, pliers, screwdrivers and socket sets, or more vehicle-specific tools, such as cylinder hones, piston-ring compressors, and vehicle brake tools. The tools used by vehicle technicians may also include electronic tools such as a vehicle scan tool or a digital voltage-ohm meter (DVOM), for use in diagnosing and/or repairing a vehicle. 
     The vehicle scan tool and/or DVOM can be linked via wired and/or wireless link(s) to other devices, perhaps to communicate data about the vehicle. The vehicle scan tool and/or DVOM can provide a significant amount of data to aid diagnosis and repair of the vehicle. This data is provided using a number of different functions of the vehicle scan tool and/or DVOM including functions for scanning for diagnostic data and functions performing tests on the vehicle.

     DETAILED DESCRIPTION 
     Outputting Diagnostic Content Based on Capabilities of Diagnostic Devices 
     A vehicle scan tool is an electronic device, which may be a computing device, that can be used to repair one or more vehicles at least by communicating with the vehicle(s), diagnosing faults in the vehicle(s), performing tests on the vehicle(s), setting one or more states of one or more components of the vehicle(s) (e.g., setting a state of a component to be on, off, or to some other particular state), calibrating one or more components and/or systems of the vehicle(s), and/or programming and/or reprogramming one or more components of the vehicle(s). The vehicle scan tool can provide a user interface to allow a user, such as a technician repairing a vehicle, to control operations of the vehicle scan tool. In some cases, the user interface can provide one or menu menus of options for selecting a particular operation to be performed by the vehicle scan tool. 
     A vehicle is a mobile machine that can be used to transport a one or more people and/or cargo. A vehicle can be driven or otherwise guided along a path (e.g., a paved road or otherwise) on land, in water, or in the air or outer space. A vehicle can be wheeled, tracked, railed, or skied. A vehicle can be guided by a user within the vehicle or by a user outside of the vehicle by use of a remote control. A vehicle can be guided at least partially autonomously. In the case of an autonomous vehicle, the vehicle can at least sometimes be guided along a path without any person or cargo inside or on the vehicle. A vehicle can include an automobile, a motorcycle, an all-terrain vehicle (ATV) defined by ANSI/SVIA-1-2007, a snowmobile, a personal watercraft (e.g., a JET SKI® personal watercraft), a light-duty truck, a medium-duty truck, a heavy-duty truck, a semi-tractor, a farm machine, a van (such as a dry or refrigerated van), a tank trailer, a platform trailer, or an automobile carrier. A vehicle can include or use any appropriate voltage or current source, such as a battery, an alternator, a fuel cell, and the like. A vehicle can include or use any desired drive system or engine. That drive system or engine can include items that use fossil fuels, such as gasoline, natural gas, propane, and the like, electricity, such as that generated by a battery, magneto, fuel cell, solar cell and the like, wind and hybrids or combinations thereof. Example vehicles include, but are not limited to, one or more automobiles, light-duty trucks, heavy-duty trucks, construction equipment, train cars, amphibious vehicles, boats, ships, seacraft, hovercraft, gliders, helicopters, airplanes, and/or aircraft. 
     A vehicle manufacturer can build various quantities of vehicles each calendar year (i.e., January 1 st  to December 31 st ). In some instances, a vehicle manufacturer defines a model year for a particular vehicle model to be built. The model year can start on a date other than January 1 st  or can end on a date other than December 31 st . The model year can span portions of two calendar years. A vehicle manufacturer can build one vehicle model or multiple different vehicle models. Two or more different vehicle models built by a vehicle manufacturer during a particular calendar year can have the same of different defined model years. The vehicle manufacturer can build vehicles of a vehicle model with different vehicle options. For example, the particular vehicle model can include vehicles with six-cylinder engines and vehicles with eight-cylinder engines. The vehicle manufacturer or another entity can define vehicle identifying 
       FIG.  1    shows scenario  100  using a prior art vehicle scan tool. Scenario  100  starts with the vehicle scan tool providing data entry screen  110  as shown at upper left of  FIG.  1   . The data entry screen requests input about a vehicle including a “Year”, “Make”, “Model”, and “# of Cylinders”. After providing the requested input about the vehicle, the prior art vehicle scan tool displays screen  120  shown at upper center of  FIG.  1   . During scenario  100 , the input provided for “Year” is 2008, for “Make” is Honda, for “Model” is Civic, and for “# of Cylinders” is 4, as shown at the top of the screen shown at upper center of  FIG.  1   . Screen  120  also provides a user with a menu having four options: option “1” of “Codes Menu”, option “2” of “Data Display”, option “3” of “Functional Tests” and option “4” of “Troubleshooter”, as well as showing an input provided by the user of “3” to take the functional tests option. 
     After receiving the input to take the functional tests option, the prior art vehicle scan tool displays screen  130 , shown at upper right of  FIG.  1   . Screen  130  presents another menu for the user having four options related to “Functional Tests”: option “1” of “Engine Tests”, option “2” of “Misfire Data Tests”, option “3” of “Resets” and option “4” of “Calibration Tests”, as well as showing an input provided by the user of “1” to take the engine tests option. After receiving the input to take the engine tests option, the prior art vehicle scan tool displays screen  140  shown at lower left of  FIG.  1   . Screen  140  presents another menu for the user having three options related to “Engine Tests” of “Functional Tests”: option “1” of “Functional Test 1”, option “2” of “Functional Test 2”, option “3” of “Functional Test 3”, as well as showing an input provided by the user of “2” to take the functional test 2 option. 
     After receiving the input to take the functional test 2 option, the prior art vehicle scan tool displays screen  150 , shown at lower center of  FIG.  1   . Screen  150  presents a display requesting an input of “Enter” to “proceed with Functional Test 2” or an input of “X” to “Exit”; i.e., cancel performance of functional test 2. In scenario  100 , an enter input is provided to the prior art vehicle scan tool while displaying screen  150 . After receiving the enter input, the prior art vehicle scan tool begins performing the test and displays screen  160  shown at lower right of  FIG.  1    indicating that performance of functional test 2 has begun. After displaying screen  160 , scenario  100  ends. 
     As illustrated by scenario  100 , using menu-based user interfaces for vehicle scan tools such as shown in  FIG.  1    can be cumbersome. For example, to perform one test in scenario  100 , the user had to enter data about the vehicle and navigate two menus to find the test to be performed before test execution could begin. In other scenarios, prior art vehicle scan tools using menu-based user interfaces can require navigation of more (and perhaps many more) than two menus before carrying out a desired task, such as running a functional test as in scenario  100 . Such menu-based user interfaces can lead to user error in selecting options, wasting time in reading menus and providing respective inputs to find and then carry out a desired task, and, in some cases, can lead to user frustration in repetitively navigating menus to perform often-requested tasks. 
     To address at least these deficiencies in prior art vehicle scan tools, a herein-described vehicle scan tool or other computing device can receive a “functional task setup” to direct the vehicle scan tool to perform a particular task on a particular vehicle. The functional task setup can be provided to the vehicle scan tool via one or more messages from a remote computing device that may be distant or remote from the vehicle scan tool. For example, a user of a vehicle scan tool may use the remote computing device to obtain vehicle service information regarding a vehicle under repair. In repair shops with multiple technicians, the remote computing device could be a common computing device used by the multiple technicians, where the repair shop subscribes to a service to obtain top rate service information from a service provider like Snap-on Incorporated or Mitchell1®. Additionally or alternatively, the remote computing device could be the user&#39;s personal smart phone. 
     In any event, the remote computing can display a page with hypertext (or similar) links related to vehicle repair; e.g., a page displaying information about a repair procedure for vehicular repair with links corresponding to tests and/or other operations to be performed by the vehicle scan tool on a vehicle under repair as part of the repair procedure. Then, in response to selection of a link on the page, the remote computing device or a related computing device, such as a server connected to the computing device, can generate a message with a functional task setup corresponding to the link and send the message with the functional task setup to the vehicle scan tool. Other scenarios for generating and providing functional task setups are possible as well. 
     The functional task setup can include at least two identifiers: a vehicle identifier identifying the particular vehicle and a task identifier identifying one or more tasks to be performed on the particular vehicle. Examples of the one or more tasks include, but are not limited to, tasks for: transmitting a message to one or more electronic control units (ECUs) of the particular vehicle, performing one or more component tests of one or more components of the particular vehicle, performing one or more functional tests of one or more components of the particular vehicle, performing one or more reset procedures of one or more components of the particular vehicle, calibrating one or more components of the particular vehicle, and reprogramming one or more ECUs of the particular vehicle. In some examples, the particular vehicle can be identified using data such as year/make/model/engine (YMME) data, where the YMME data can include data about a year of manufacture of the particular vehicle, a manufacturer of the particular vehicle, a model of the particular vehicle, and/or data about an engine of the particular vehicle. In other examples, the particular vehicle can be identified using part or all of a vehicle identification number (VIN). Other data can be used to identify a particular vehicle as well or instead. 
     Upon reception of the functional task setup, the vehicle scan tool can determine whether the vehicle scan tool is available to perform the functional task(s) identified in the functional task setup. For example, the vehicle scan tool can determine whether the vehicle scan tool is already performing another functional task. If the vehicle scan tool is not performing another functional task, then the vehicle scan tool can be available to perform the functional task(s). Otherwise, if the vehicle scan tool is performing another functional task, then the vehicle scan tool may not be available at least until the vehicle scan tool completes the functional task being performed. If the vehicle scan tool is not available, the vehicle scan tool can provide an indication that the functional task setup has been received, that the functional task already being performed has been completed and/or that the vehicle scan tool is now available to perform the functional task(s) identified in the functional task setup. In some cases, the functional task setup can be selected from the vehicle scan tool that displays service information in a non-scan tool mode of the vehicle scan tool. 
     Once the vehicle scan tool is available to perform the functional task(s) identified in the functional task setup, the vehicle scan tool can generate a display requesting an input to initiate performance of the functional task(s). Such an input can be requested to ensure that the vehicle scan tool is properly connected to the particular vehicle, that it is safe to begin the test, to coordinate actions between the vehicle scan tool and one or more users of the vehicle scan tool, and/or for other reasons. 
     After receiving the input, the vehicle scan tool can communicate with the particular vehicle to perform the functional task(s) identified in the functional task setup. For example, the vehicle scan tool can send and/or receive one or more messages to and/or from the particular vehicle while performing the functional task(s). While and/or after communicating with the vehicle, the vehicle scan tool can display one or more notifications indicating that the functional task(s) are being performed. 
     The vehicle scan tool can complete the functional task(s) identified in the functional task setup. After completing the functional task(s), the vehicle scan tool can provide one or more indications that the functional task(s) have been completed. In some examples, the indication(s) that the functional task(s) have been completed can include test results, test status information (e.g., fully completed, partially completed test), and/or other data related to the completed functional task(s). In other examples, the vehicle scan tool can directly or indirectly send a message to one or more other computing devices, where the message represents one or more notifications and is sent instead of (or along with) displaying the notification(s) on the vehicle scan tool. For example, the one or more other computing devices can include the above-mentioned servers and/or the above-mentioned remote computing device. For example, as the remote computing device previously sent the functional task setup, the remote computing device can receive the notification(s) and can generate one or more displays based on the notifications. 
     The herein-described techniques enable remote operation of the vehicle scan tool from one or more other computing devices. The other computing device(s) can send functional task setups to the vehicle scan tool. Then, the vehicle scan tool can execute one or more functional tasks as indicated by the received functional task setups. As a functional task setup includes a vehicle identifier, the vehicle scan tool can verify that functional task(s) are executed on a vehicle identified by the vehicle identifier and not on some other vehicle, thereby ensuring the functional task(s) are executed on the correct vehicle. Also, by enabling selection of a link, button, or other user-interface element, a user of the other computing device(s) can generate and send functional task setups with minimal effort. In examples where the vehicle scan tool responds to functional task setups with notification messages, the notification message(s) can be used to generate one or more displays of the other computing device(s) sending the functional task setup(s), thereby both providing feedback on the functional task setups and enabling remote repair sessions of vehicles using the other computing device(s). By enabling remote operation and by reducing the number of menus (or related user interface entities) to perform a task, the herein-described techniques, methods, and devices can simplify, ease, and speed use and widen the availability of the vehicle scan tool. 
       FIG.  2    is a flowchart of method  200 , in accordance with an embodiment. Part or all of method  200  can be performed by a computing device acting as and/or embodied as a server. The server can be connected to at least two computing devices: a computing device CD1 acting as a vehicle scan tool and a computing device CD2 providing notifications of link selections to the server. Method  200  relates to using computing devices CD1, CD2, and the server to conduct a repair session S1 to repair a repair a vehicle V1. Each of computing devices CD1, CD2, and the server can be computing devices such as computing device  1300  discussed below at least in the context of  FIG.  13 A . 
     Method  200  can begin at block  210 , where the server can receive an indication of a selection of link L1, where the indication is sent from computing device CD2 to the server. Link L1 can be received in one or more messages (such as one or more link messages) and can be related to a repair session S1 for repairing vehicle V1, where the repair session involves use of computing device CD1 acting as a vehicle scan tool. The indication of a selection of link L1 can include an identifier ID1 identifying vehicle V1 and a menu selection MS1 indicating a menu selection of a menu related to performance of a task T1 to be performed on vehicle V1. In some examples, ID1 can include YMME and/or VIN information identifying vehicle V1. In other examples, the menu selection MS1 can be replaced by a type of identifier related to task T1 other than an identifier of a menu selection; e.g., ID2 discussed below in the context of block  220 . In even other examples, link L1 can further include an identifier SCAN_CD and/or related data that identifies a computing device acting as a vehicle scan tool to be used to execute task T1. In still other examples, task T1 can be one or more of: a task of transmitting a message to an ECU of vehicle V1, a task of performing one or more component tests of a particular component of vehicle V1, a task of performing one or more functional tests of a particular component on vehicle V1, a task of performing a reset procedure to the particular component on vehicle V1, a task of calibrating a system including the particular component on vehicle V1, and a task of reprogramming an ECU of vehicle V1. 
     Table 1 below lists example component tests, functional tests, and resets that can be performed as task T1 for an example vehicle. Other tasks than those mentioned herein can be performed as task T1 as well.

     At block  220 , the server can determine an identifier ID2 of task T1 based on menu selection MS1, where ID2 can be used by computing device CD1 to identify task T1 to be performed on vehicle V1. For example, the server can provide menu selection MS1 as an input to a lookup table, data base, or similar data structure to determine ID2 as a resulting output. Other techniques for determining ID2 are possible as well. In some examples, the indication of the election of link L1 can include ID2 instead of, or along with, menu selection MS1—in these examples, the server can omit block  220 , as the server would already have determined ID2 at block  210 . 
     At block  230 , the server can generate a functional task setup FTS1 that includes identifiers ID1 and ID2 for respectively identifying vehicle V1 and task T1. 
     At block  240 , the server can determine a destination computing device CD1; i.e., a vehicle scan tool, to receive functional task setup FTS1 and subsequently perform task T1 on vehicle V1. To determine CD1, the server can retrieve data identifying computing device CD1; e.g., identifier SCAN_CD, from the link received at block  210 . In other examples, the server can maintain repair session data that associates computing device CD2 with the destination computing device CD1, where a particular repair session is identified in the link received at block  210  or otherwise identified; e.g., via a different message and/or other data than provided in the link. Then, by determining that computing device CD2 sent the link received at block  210  and by finding repair session data associated with computing device CD2, the server can determine destination computing device CD1. Other techniques for identifying a destination computing device CD1 are possible as well. 
     At block  250 , the server can send functional task setup FTS1 to destination computing device CD1. Upon reception of functional task setup FTS1, computing device CD1 can use some or all of the procedures of method  300  to perform task T1 on vehicle V1 and provide an output O1 related to the performance of task T1 to the server. Output O1 can be, but is not limited to: a status indicator of task T1 (e.g., task completed, task not completed, task partially completed), data related to task T1 (e.g., data for one or more measurements taken as part of task T1, other data provided by vehicle V1 to computing device C1 during performance of task T1), and/or information about a display related to task T1. 
     At block  260 , the server can receive the output O1 related to the performance of task T1; e.g., receive output O1 from computing device CD1. 
     At block  270 , the server can provide the output O1 to computing device CD2. In some examples, the server can modify output O1 prior to providing the output O1 to computing device CD2; e.g., add, update, and/or delete data from output O1, reformat part or all of output O1, remove message-related data, such as one or more message headers and/or extract output O1 from a message received at block  260  by the server. Upon completion of the procedures of block  270 , method  200  can be completed. 
       FIG.  3    is a flowchart of method  300 , in accordance with an embodiment. Part or all of method  300  can be performed by a computing device CD1 acting as and/or embodied as a vehicle scan tool to repair a vehicle V1, such as computing device  1300  discussed below at least in the context of  FIG.  13 A . 
     Method  300  can begin at block  310 , where computing device CD1 can start a new repair session S1. Starting the new repair session S1 can include computing device CD1 creating and/or initializing data associated with repair session S1. 
     At block  320 , computing device CD1 can receive a functional task setup FTS1, where FTS1 includes identifiers ID1 and ID2. Identifier ID1 can identify a vehicle V1 and identifier ID2 can identify a task T1 to be performed on vehicle V1 using computing device CD1. At least functional task setup FTS1, identifier ID1, identifier ID2, and task T1 are discussed above in more detail at least in the context of method  200 . 
     In some examples, repair session S1 is associated with a vehicle V_S1 and/or repair personnel identifier RP_S1; e.g., a repair session is created when repair personnel login and begin work on a vehicle—repair session S1 can be associated with data identifying the vehicle as V_S1 and/or the repair personnel&#39;s user name (or other identifier) as RP_S1. Then, computing device CD1 can compare identifier ID1 identifying V1 with the vehicle V_S1 associated with repair session S1 and/or compare a repair personnel identifier ID_RP in functional task setup FTS1 with repair personnel RP_S1 associated with repair session S1. 
     If V1 matches V_S1 and/or ID_RP matches RP_S1, then functional task setup FTS1 is also associated with repair session S1. However, if V1 does not match V_S1 and/or ID_RP does not match RP_S1, then functional task setup FTS1 is either associated with a different repair session than repair session S1 or FTS1 is not associated with a repair session being carried out by computing device CD1. Then, computing device CD1 can compare V1 and/or ID_RP with one or more vehicle identifiers associated with other repair sessions than S1 to determine whether V1 and/or ID_RP are associated with another repair session than S1. If V1 and/or ID_RP are associated with a different repair session than S1; e.g., a repair session S2, then computing device CD1 can perform task T1 in the context of the different repair session; e.g., S2. If V1 and/or ID_RP are not associated with any repair session, then computing device CD1 can perform the functionality of block  310  to create a new repair session and associate vehicle V1 and/or repair personnel ID_RP with the new repair session, or reject functional task setup FTS1 as invalid and/or unassociated with a repair session. 
     At block  330  of method  300 , computing device CD1 can determine whether CD1 is already performing another task; e.g., a task T2, that differs from task T1. For example, task T2 can be a task other than T1 that is also related to vehicle repair, such as a task for a different repair session than repair session S1 or a different task for repair session S1. If computing device CD1 is already performing task T2, then computing device CD1 can proceed to block  332 . Otherwise, computing device CD1 is not performing another task, and computing device CD1 can proceed to block  340 . 
     At block  332 , computing device CD1 can display a notification N1 and/or provide an indication IND1 that computing device CD1 has received functional task setup FTS1 and computing device CD1 that is busy performing another task (e.g., task T2). For example, computing device CD1 can display notification N1 on a screen or other display of CD1. As another example, computing device CD1 can send a message that includes indication IND1 to the server of method  200 . Other examples of displaying N1 and/or providing IND1 are possible as well. 
     Upon completion of block  332 , computing device CD1 can proceed to block  330 . In some examples, computing device CD1 can proceed to block  330  after waiting for a predetermined amount of time and/or after waiting for completion of task T2; e.g., wait for one or more seconds, wait and check for completion of task T2 at fixed intervals of time; e.g., at 0.5, 1, 2, 5, 15, 30, 60, and/or 120 second intervals. 
     At block  340 , computing device CD1 can determine whether CD1 is connected to a vehicle. In one example, computing device CD1 can send one or more messages, pulses, and/or other outputs over one or more connections, ports, cables, and/or other devices that can be used to connect to a vehicle. In another example, computing device CD1 can send a message via an On-Board Diagnostics (OBD) port/connection, such as a message requesting a vehicle send a VIN or other data using the OBD-II or related protocol. In another example, a connection between computing device and a vehicle can be made by turning the vehicle on (e.g., turning an ignition key to run) and/or starting a vehicle. After sending the output(s), computing device CD1 can receive and/or wait for one or more responses to the sent outputs and use the responses (if any) to determine whether CD1 is connected to a vehicle. 
     If computing device CD1 determines that CD1 is connected to a vehicle, then computing device CD1 can proceed to block  350 . Otherwise, computing device CD1 determines that CD1 is not connected to a vehicle, and computing device CD1 proceed to block  342   
     At block  342 , computing device CD1 can display a notification N2 and/or provide an indication IND2 that computing device CD1 has received functional task setup FTS1, if notification N1 and/or indication IND2 were not displayed and/or provided at block  332 . Also, computing device CD1 can display a notification N3 and/or provide an indication IND3 to connect computing device CD1 to vehicle V1. Upon completion of the procedures of block  342 , computing device CD1 can proceed to block  340 , perhaps after waiting a predetermined amount of time (e.g., 30, 45, 60, 90, or 120 seconds to provide time to connect CD1 to a vehicle V1) and/or after receiving an indication that computing device CD1 is connected to a vehicle. 
     At block  350 , computing device CD1 can determine whether CD1 is connected to vehicle V1. For example, computing device CD1 can send a message via an OBD port/connection, such as a message M1 to the connected vehicle requesting the VIN or other identifying information about the connected vehicle using the OBD-II or related protocol. Then, computing device CD1 can receive a response R1 to message M1 and compare part or all of response R1 with part or all of identifier ID1 to determine whether CD1 is connected to vehicle V1. Other techniques to determine whether CD1 is connected to vehicle V1 are possible as well. 
     If computing device CD1 is connected to vehicle V1, then computing device CD1 can proceed to block  352 . Otherwise, computing device CD1 is not connected to vehicle V1 and computing device CD1 can proceed to block  342 . 
     At block  352 , computing device CD1 can receive an input to initiate performance of task T1. For example, computing device CD1 can display a request for input to initiate task T1 on a screen of CD1 or another display. Such an input can provide verification that it is safe to initiate task T1 and/or that vehicle V1 and computing device CD1 are ready for task initiation. In some examples, the procedures of block  352  are omitted. 
     At block  354 , computing device CD1 can perform task T1 as identified by identifier ID2. 
     At block  356 , computing device CD1 can, upon completion of task T1 (or a determination that task T1 cannot be completed), provide an output related to the performance of task T1 to the server, such as output O1 discussed above in the context of block  250  of method  200 . 
     At block  360  of method  300 , computing device CD1 can determine whether repair session S1 is complete. For example, functional task setup FTS1 can include an indication whether a repair session is complete and/or data on computing device CD1 can be used to determine whether repair session S1 is complete. If repair session S1 is complete, then computing device CD1 can proceed to block  370 . Otherwise, repair session S1 is not complete and computing device CD1 can proceed to block  320 . 
     At block  370 , computing device CD1 can end repair session S1. Upon completion of the procedures of block  370 , method  300  can be completed. 
       FIGS.  4 ,  5 ,  6 ,  7 ,  8 ,  9 , and  10    depict aspects of scenario  400  of repairing two vehicles V1 and V2. Scenario  400  begins with computing device CD1, acting as a vehicle scan tool, being connected to vehicle V2. Also, computing device CD2 receives inputs identifying a task T1 to be performed on vehicle V1 as part of a repair session for vehicle V1—in scenario  400 , the inputs are received, in part, by clicking on a link of a display describing a repair procedure being followed to diagnose and repair vehicle V1. 
     After receiving the inputs identifying a task T1 to be performed on vehicle V1, computing device CD2 can send a link  426  to server  410 . Upon reception of link  426 , server  410  can use the techniques of method  200  to process link  426 . Server  410  can determine computing device CD1 and/or technician TECH1 that are associated with computing device CD2 that sent link  426 . Then, server  410  can generate functional task setup  440  with identifiers ID1 and ID2 respectively identifying vehicle V1 and task T1 and send a message with functional task setup  440  to computing device CD1. Upon reception of the message with functional task setup  440 , computing device CD1 can use the procedures of method  300  to determine that computing device CD1 is not connected to vehicle V1 (rather, CD1 is connected to vehicle V2) and display a notification of receipt of functional task setup  440  and a notification to have TECH1 connect CD1 to vehicle V1. Computing device CD1 can then be disconnected from vehicle V2 and connected to vehicle V1. After computing device CD1 is connected to vehicle V1, CD1 can receive an input to start task T1 on vehicle V1 and subsequently initiate performance of task T1 on vehicle V1. 
     Scenario  400  continues with computing device CD2 receiving inputs to perform a task T2 on vehicle V1. After receiving the inputs identifying task T2 to be performed on vehicle V1, computing device CD2 can send a link  510  to server  410 . Upon reception of link  510 , server  410  can use the techniques of method  200  to process link  510 . Server  410  determine computing device CD1 and/or technician TECH1 that are associated with computing device CD2 that sent link  510 . Then, server  410  can generate functional task setup  530  with identifiers ID1 and ID3 respectively identifying vehicle V1 and task T3 and send a message with functional task setup  530  to computing device CD1. Upon reception of the message with functional task setup  530 , computing device CD1 can use the procedures of method  300  to determine that computing device CD1 is connected to vehicle V1 and display a notification of receipt of functional task setup  530  associated with task T2 and that computing device CD1 is still busy performing another task T1 and provide a related notification to server  410 . 
     Scenario  400  can continue with computing device CD1 completing task T1 on vehicle V1 and obtaining output O1 associated with task T1. After obtaining output O1, computing device CD1 can provide O1 to server  410 , and server  410  can provide output O1 to computing device CD2. Computing device CD2 can then generate a display related to output O1. 
     Scenario  400  can proceed with computing device CD1 displaying a notification requesting input to start task T2 on vehicle V1. After receiving the input to start task T2, CD1 can perform task T2 on vehicle V1 to obtain output O2 associated with task T2. Computing device CD1 can then provide output O2 to server  410 , and server  410  can provide output O2 to computing device CD2. Computing device CD2 can then generate a display related to output O2 and scenario  400  can be completed. 
       FIGS.  4  and  5    together show a communication flow for scenario  400 , in accordance with an embodiment.  FIG.  4    illustrates that scenario  400  begins with computing device CD1 being connected to vehicle V2 as indicated using connect message(s)  420 . Computing device CD2 receives data for identifier ID1 identifying vehicle V1 and receives a selection MS1 associated with performance of task T1, as shown in respective blocks  422  and  424 . In some cases, selection MS1 can be a menu selection; e.g., an identifier for a particular menu of a user interface provided by computing device CD1. In other cases, selection MS1 can identify a function, method, object, address, or other software entity of computing device CD1 to utilize and/or execute to perform task T1. Other types of selections associated with tasks can be used for selection MS1 and/or other herein-described selections (e.g., selection MS2) are possible as well. 
       FIG.  6    shows display  600  related to verifying operation of injectors of a vehicle generated by computing device CD2 during scenario  400 , in accordance with an embodiment. Display  600  is generated by CD2 after performing the procedures of block  422  and before performing the procedures of block  424 . 
     Display  600  indicates that a “menu system” of computing device “CD1” can be used to navigate to a “Injector Balance” screen by first using a “Scanner” menu, then proceeding to a “System” menu, further proceeding to an “Engine” menu, continuing on to a “Functional Tests” menu, which can be used to navigate to the “Injector Balance” screen. According to display  600 , computing device “CD1” will “display some instructions for connecting fuel lines and a fuel pressure gauge between CD1 and the vehicle being repaired” after “displaying the Injector Balance Screen”. Then, after “[m]ak[ing] sure the vehicle&#39;s ignition is ON and its engine is OFF”, the “menu system of CD1” can be used to select “Continue” in order “to start injector testing”. 
     Display  600  also describes an alternative to using the menu system of computing device CD1. The alternative involves “[e]nsur[ing] that . . . fuel lines for the vehicle being repaired are connected to CD1”, a “fuel pressure gauge is connected to the fuel line of the vehicle”, the “vehicle&#39;s Ignition is ON”, and that the “vehicle&#39;s Engine is OFF.” After ensuring these items, a user of computing device CD2 can “take” link  610  “to direct CD1 to begin injector testing one injector at a time”. That is, repair personnel can use a menu system to navigate through four screens before reaching an “Injector Balance” screen that enables initiation of injector testing to a vehicle connected to computing device CD1, or the repair personnel can take one link—link  610 —to initiate injector testing to the vehicle connected to computing device CD1. Repair personnel can save time and avoid potential error by taking link  610  to initiate injector testing in comparison to using computing device CD1&#39;s menu system to initiate injector testing. 
     Display  600  also includes links  620  for individual injector testing of up to eight injectors—links  620  include link  622  to toggle (i.e., test) “Injector #3”, link  624  to toggle “Injector #6”, and link  626  to toggle “Injector #8”. Display  600  also includes button  630  that, when selected, allows the user to end a repair session; e.g., end session S1 in scenario  400 . Display  600  further instructs repair personnel to “[c]ompare fuel pressure loss for all injectors to verify injector operation”. 
     At this stage of scenario  400 , link  622  is selected using computing device CD2, causing computing device CD2 to generate and send link  426 , where MS1 relates to a selection for testing injector #3 of vehicle V1 corresponding to link  622 . 
       FIG.  4    indicates that, after receiving the data for identifier ID identifying vehicle V1 and the selection MS1 for testing injector #3, computing device CD2 generates and sends link  426  to server  410  with identifier “ID1” identifying vehicle V1, selection “MS1” related to task T1, and data “CD1” identifying computing device CD1 as a computing device/vehicle scan tool to perform task T1 on vehicle V1. 
     In scenario  400 , identifier ID includes YMME and VIN information about vehicle V1 and task T1 involves testing injector #3 as also indicated by selection MS1. In other scenarios, identifier ID1 includes only YMME information about a vehicle, only VIN information about a vehicle. In still other scenarios, identifier ID1 includes other information identifying a vehicle other than YMME and/or VIN information; e.g., one or more names of an owner of a vehicle, one or more identifiers of one or more repair orders or other data associated with the repair session, one or more serial numbers for a vehicle, etc. In even other scenarios, selections MS1 and MS2 can refer to more and/or different respective tasks than T1 and T2. 
     Server  410  then utilizes the procedures of block  210  of method  200  to receive link  426 . After receiving link  426 , server  410  utilizes the procedures of block  220  of method  200  to translate received selection MS1 to an identifier ID2 associated with a task T1, as shown at block  430 . 
     Server  410  then utilizes the procedures of block  230  of method  200  to generate a functional task setup that includes identifier ID1 identifying vehicle V1 and identifier ID2 identifying task T1, as shown at block  432 . Block  434  indicates that server  410  utilizes the procedures of block  240  of method  200  to determine that computing device CD1 is to receive the functional task setup generated at block  432 . In scenario  400 , server  410  uses data “CD1” in link  426  that identifies computing device CD1 as the destination for the functional task setup generated at block  432 . Server  410  then sends a message with functional task setup  440  with identifiers ID1 and ID2 to computing device CD1. 
       FIG.  4    indicates that computing device CD1 utilizes the procedures of block  320  of method  300  to receive the message with functional task setup  440 . Then, computing device CD1 utilizes the respective procedures of blocks  330  and  340  to determine that computing device CD1 is not performing another task and is connected to a vehicle—as indicated above, at this stage of scenario  400 , computing device CD1 is connected to vehicle V2. 
     As indicated by block  442  of  FIG.  4   , computing device CD1 utilizes the procedures of block  350  of method  300  to determine that computing device CD1 is connected to vehicle V2. Vehicle V2 is not the vehicle—vehicle V1—identified in functional task setup  440 . Block  442  also indicates that that computing device CD1 utilizes the procedures of block  342  of method  300  to display notifications of the receipt of functional task setup (FTS)  440  and that computing device CD1 should be connected to vehicle V1. 
       FIG.  7    shows computing device CD1 displaying dialog  700 , in accordance with an embodiment. Dialog  700 , which is displayed as part of the procedures of block  442 , includes a notification “Functional Task Setup Received” of the receipt of functional task setup  440  and a notification to “connect vehicle V1” to indicate that computing device CD1 should be connected to vehicle V1. As part of the notification of the receipt of functional task setup  440 , dialog  700  also indicates that functional task setup  440  relates to a vehicle “V1” and a task of an “Injector Balance Test for Injector #3”; i.e., task T1. Regarding vehicle V1, dialog  700  indicates that “V1 is not currently connected to” computing device CD1 and requests “connect[ion to] vehicle V1”. Dialog  700  also includes button  710  labeled “OK” requests that button  710  be “press[ed] . . . when ready to start with” task T1. 
     Returning to  FIG.  4   , scenario  400  continues with repair personnel disconnecting computing device CD1 from vehicle V2, as shown by disconnect message  444 . Then, repair personnel connect computing device CD1 to vehicle V1, as shown by connect message  446 , and provide an input to start task T1 for vehicle V1, as shown by block  448 . In scenario  400 , the input to start task T1 for vehicle V1 includes pressing button  710  of dialog  700  discussed above. 
     Computing device CD1 uses blocks  340 ,  350 ,  352  and  354  of method  300  to: determine that computing device CD1 is connected to vehicle V1 that is the vehicle identified in functional task setup  440 , receive the input to start task T1, and initiate performance of task T1 on vehicle V1 as part of repairing vehicle V1, as illustrated by message  450  of  FIG.  4   . 
     At this stage of scenario  400 , link  624  of display  600  shown in  FIG.  6    is selected using computing device CD2, and this link selection causes computing device CD2 to generate and send a link, where MS2 is a selection for testing injector #6 of vehicle V1 corresponding to link  624 . This link selection is illustrated by block  460  of  FIG.  4   . 
     Turning to  FIG.  5   , scenario  400  continues with computing device CD2 generating and sending link  510  to server  410  with identifier “ID1” identifying vehicle V1, selection “MS2” related to task T2, and data “CD1” identifying computing device CD1 as a computing device/vehicle scan tool to perform task T2 on vehicle V1. In scenario  400 , task T2 involves testing injector #6 as also indicated by selection MS2. 
     Server  410  then utilizes the procedures of block  210  of method  200  to receive link  510 . After receiving link  510 , server  410  utilizes the procedures of block  220  of method  200  to translate received selection MS2 to an identifier ID3 associated with task T2, as shown at block  520 . 
     Server  410  then utilizes the procedures of block  230  of method  200  to generate a functional task setup that includes identifier ID identifying vehicle V1 and identifier ID3 identifying task T2, as shown at block  522 . Block  524  indicates that server  410  utilizes the procedures of block  240  of method  200  to determine that computing device CD1 is to receive the functional task setup generated at block  522 . In scenario  400 , server  410  uses data “CD1” in link  510  that identifies computing device CD1 as the destination for the functional task setup generated at block  522 . Server  410  then sends a message with functional task setup  530  with identifiers ID1 and ID2 to computing device CD1. 
       FIG.  5    indicates that computing device CD1 utilizes the procedures of block  320  of method  300  to receive the message with functional task setup  530 . Then, computing device CD1 utilizes the procedures of block  330  to determine that computing device CD1 is still performing task T1, as indicated by block  532 . Block  532  also indicates that computing device CD1 uses the procedures of block  332  of method  300  to display a notification of the receipt of functional task setup  530  associated with task T2. 
       FIG.  8    shows computing device CD1 displaying indicator  820  to show that a “New Functional Task Setup”; e.g., functional task setup  530  was “Received”. After displaying indicator  820  as a notification of the receipt of functional task setup  530 ,  FIG.  5    shows that computing device CD1 uses the procedures of block  356  of method  300  to generate and send functional task setup output (FTSOut) message  534  to server  410 . Functional task setup output message  534  indicates that a functional task setup having identifier “ID1” identifying vehicle V1 and identifier “ID3” identifying task T2; e.g., functional task setup  530 , is not currently being performed as CD1 is “BUSY” as part of the procedures of block  332  of method  300 . 
     After computing device CD1 sends functional task setup output message  534 , computing device CD1 completes task T1 on vehicle V1, as illustrated by block  540  of  FIG.  5   . After completing task T1, computing device CD1 executes block  356  of method  300  to provide output related to the performance of task T1. In scenario  400 , task T1 involves an injector balance test of injector #3 of vehicle V1—this test indicates that an initial fuel pressure reading for injector #3 is 51 pounds per square inch (PSI) and, after pulsing injector #3, a post-pulse fuel pressure reading is 30 PSI for a fuel pressure loss for injector #3 of 21 PSI. 
       FIG.  5    shows that the output of computing device CD1 related to the performance of task T1 includes sending functional task setup output message  542  to server  410 . Functional task setup output message  542  indicates that a functional task setup having identifier “ID1” identifying vehicle V1 and identifier “ID2” identifying task T1; e.g., functional task setup  440 , has an output “O1”. In scenario  400 , output O1 includes data that the fuel pressure loss for injector #3 is 21 PSI. 
     In scenario  400 , the output of computing device CD1 related to the performance of task T1 also includes providing a display of computing device CD1 indicating performance of task T1.  FIG.  8    shows computing device CD1 displaying dialog  800  indicating performance of task T1 related to an “Injector Balance Test for Injector #3”, where the “Initial Fuel Pressure Reading” is “51” PSI. Then, after “Pulsing Injector #3”, dialog  800  indicates a “post-pulse Fuel Pressure reading for Injector #3” is “30” PSI, for a “Fuel Pressure Loss for Injector #3” of “21 PSI”. Dialog  800  also indicates that the “Test [is] completed”; i.e., task T1 has been completed, and requests an input e.g., pressing or other selection of “OK” button  810  “to proceed”. 
       FIG.  5    shows that scenario  400  proceeds with server  410  generating and sending link output message  544  to computing device CD2, where link output message  544  has identifiers ID1 and ID2 and output O1 that are the same as in functional task setup output message  542 ; i.e., server  410  effectively forwards functional task setup output message  542  to computing device CD2 as link output message  544 . Upon reception of link output message  544 , computing device CD2 displays an output as indicated at block  546 . In scenario  400 , the output of computing device CD2 displayed at block  546  includes dialog  900 .

Functional task setup output message  560  indicates that a functional task setup having identifier “ID1” identifying vehicle V1 and identifier “ID3” identifying task T2; e.g., functional task setup  530 , has an output “O2”. In scenario  400 , output O2 includes data that the fuel pressure loss for injector #6 is 15 PSI. 
       FIG.  5    shows that scenario  400  proceeds with server  410  generating and sending link output message  562  to computing device CD2, where link output message  562  has identifiers ID1 and ID3 and output O2 that are the same as in functional task setup output message  560 ; i.e., server  410  effectively forwards functional task setup output message  560  to computing device CD2 as link output message  562 . Upon reception of link output message  562 , computing device CD2 displays an output as indicated at block  564 . In scenario  400 , the output of computing device CD2 displayed at block  564  is dialog  1100 .

FIG.  11    shows that dialog  1100  of computing device CD2 provides “Results of Injector Balance Testing” that includes previously-received output  910  from output O1 for task T1 and output O2 for task T2. Dialog  1100  and output  910  state that the “Fuel Pressure Loss” of “Injector 3” is “21 PSI”. Dialog  1100  and output  1110  from output O2 for task T2 further states that the “Fuel Pressure Loss” of “Injector 6” is “15 PSI”. Dialog  1100  also includes button  1120  that, when selected, causes computing device CD2 to close dialog  1100  and continue with repair session S  1 . After computing device CD2 displays dialog  1100 , scenario  400  can be completed. 
     In other scenarios, more, fewer, and/or different tasks can be performed during a repair session for vehicle V1. In still other scenarios, more, fewer, and/or different tasks can be performed during a repair session for one or more vehicles other than vehicle V1; e.g., vehicle V2. Many other scenarios involving repair sessions for repairing vehicles are possible as well.

       FIG.  12    is a block diagram of example computing network  1200  in accordance with an example embodiment. In  FIG.  12   , servers  410 ,  1210 , and  1212  are configured to communicate, via a network  1206 , with computing device  1224  at repair facility  1220  and perhaps with technician  1222 , as well as with client devices  1204   a ,  1204   b , and  1204   c .

In these alternative embodiments, for example, functions described as blocks, transmissions, communications, requests, responses, and/or messages may be executed out of order from that shown or discussed, including substantially concurrent or in reverse order, depending on the functionality involved. Further, more or fewer blocks and/or functions may be used with any of the ladder diagrams, scenarios, and flow charts discussed herein, and these ladder diagrams, scenarios, and flow charts may be combined with one another, in part or in whole. 
     A block that represents a processing of information may correspond to circuitry that can be configured to perform the specific logical functions of a herein-described method or technique. Alternatively or additionally, a block that represents a processing of information may correspond to a module, a segment, or a portion of program code (including related data). The program code may include one or more instructions executable by a processor for implementing specific logical functions or actions in the method or technique. The program code and/or related data may be stored on any type of computer readable medium such as a storage device including a disk or hard drive or other storage medium. 
     The computer readable medium may also include non-transitory computer readable media such as computer-readable media that stores data for short periods of time; e.g., volatile memory, register memory, processor cache, and/or random access memory (RAM). The computer readable media may also include non-transitory computer readable media that stores program code and/or data for longer periods of time; e.g., non-volatile memory, secondary or persistent long term storage, read only memory (ROM), optical or magnetic disks, compact-disc read only memory (CD-ROM). The computer readable media may also be any other volatile or non-volatile storage systems. A computer readable medium may be considered a computer readable storage medium, for example, or a tangible and/or non-transitory storage medium and/or device. 
     Moreover, a block that represents one or more information transmissions may correspond to information transmissions between software and/or hardware modules and/or executables in the same physical device. However, other information transmissions may be between software and/or hardware modules and/or executables in different physical devices. 
     Numerous modifications and variations of the present disclosure are possible in light of the above teachings.
