Allison DOC® for 6th Generation Controls Release

MODELS AFFECTED:All 1000, 2000, 3000, and 4000 Series Transmissions

Introduction:
To align with Allison’s 6th Generation Controls, Allison DOC® Subscription, V2021.3 was released in October 2021.
V2021.3 builds on some basic 6th Generation support that was added in prior Allison DOC® releases and included
the 1000 and 2000 Series and 3000 and 4000 Series troubleshooting manuals.

6th Generation Cybersecurity:
Allison has introduced new product cybersecurity measures in 6th Generation Controls to protect the integrity andsecurity of our products and systems. These new cybersecurity measures require that the Allison DOC® software
is able to authenticate with the TCM when performing reprogramming and most action requests. Allison DOC®
software authenticates with the TCM by performing a certificate exchange with the TCM and retrieving a challenge
response from Allison’s Product Cybersecurity Services (PCS) system. The authentication process requires either
the Allison DOC® software to have a real-time internet connection to PCS or the installation of a cybersecurity
USB dongle on the same computer with the Allison DOC® software. More details regarding the cybersecurity
USB dongle are provided later in this SIL.
NOTE: Only Allison DOC® Premium licenses require authentication. Allison DOC® Fleets licenses do not
require authentication because reprogramming is not available in Allison DOC® Fleets licenses. Also,none of the action requests requiring authentication are available with Allison DOC® Fleets licenses.

Reprogramming with Online Connection to PCS:
When reprogramming a 6th Gen TCM while connected to the internet, the Allison DOC® user must log into
PCS. Either TCM ReflashTM account credentials or Allison HUBTM account credentials can be used to log into
PCS through Allison DOC®. If the user has both TCM ReflashTM and Allison HUBTM account credentials, theTCM ReflashTM credentials are preferred.
NOTE: It is important to remember that when using TCM ReflashTM credentials to log into PCS, thepassword must be entered in all caps. This is only applicable to logging into PCS. When logging into TCM
ReflashTM, the password can be entered as normal (mixed case).
When the “Reprogram” menu is selected while connected to a 6th Gen TCM, the pop-up shown in Figure 1 will bedisplayed. Since this section of the SIL discusses an online connection, the user will select the radio button “yes”
for the question “Will this PC have internet access during 6th Gen TCM reprogramming and action requests?”. The
user must then enter the appropriate credentials and select “Access PCS”. If the credentials are valid, the user will

Reprogramming Offline with USB Dongle:
When reprogramming a 6th Gen TCM while offline, the Allison DOC® user must have an Allison cybersecurity USB
dongle installed on the same computer with the Allison DOC® software. When the “Reprogram” menu is selected
while connected to a 6th Gen TCM, the pop-up shown in Figure 3 will be displayed. Since this section of the SIL
discusses being offline, the user will select the radio button “no” for the question, “Will this PC have internet accessduring 6th Gen TCM reprogramming and action requests?”. The user will then enter the PIN assigned to the USB
dongle and select “Unlock USB Dongle”. If the PIN is valid, the user will see a success response as shown in
Figure 4, which also includes the number of remaining signs left on the USB dongle (more information on USB
dongle is contained in a later section of this SIL). Clicking “OK” to the pop-up in Figure 4 allows the user to proceedwith reprogramming the 6th Gen TCM in the same way that 5th Gen TCMs are reprogrammed.

Performing Action Requests with Online Connection to PCS:
When performing action requests on a 6th Gen TCM while connected to the internet, the Allison DOC® user must
log into PCS. Similar to reprogramming, either TCM ReflashTM account credentials or Allison HUBTM accountcredentials can be used to log into PCS through Allison DOC®. If the user has both TCM ReflashTM and Allison
HUBTM account credentials, the TCM ReflashTM credentials are preferred.
NOTE: It is important to remember that when using TCM ReflashTM credentials to log into PCS, thepassword must be entered in all caps. This is only applicable to logging into PCS. When logging into TCM
ReflashTM, the password can be entered as normal (mixed case).
Not all action requests require authentication with the TCM. A list of action requests requiring authentication isshown in Table 1. When an action request requiring authentication is selected from the “Action Request” menu
while connected to a 6th Gen TCM, the pop-up shown in Figure 1 will be displayed. Since this section of theSIL discusses an online connection, the user will select the radio button “yes” for the question “Will this PC
have internet access during 6th Gen TCM reprogramming and action requests?” The user must then enter theappropriate credentials and select “Access PCS”. If the credentials are valid, the user will see a success response
as shown in Figure 2. Clicking “OK” to the pop-up in Figure 2 allows the user to proceed with performing the action
request on the 6th Gen TCM in the same way that 5th Gen TCMs action requests are performed.

Performing Action Requests Offline with USB Dongle:
When performing action requests on a 6th Gen TCM while offline, the Allison DOC® user must have an Allison
cybersecurity USB dongle installed on the same computer with the Allison DOC® software. The of list of action
requests requiring authentication shown in Table 1 also applies when using the USB dongle offline.
When an action request requiring authentication is selected from the “Action Request” menu while connected to a
6th Gen TCM, the pop-up shown in Figure 3 will be displayed. Since this section of the SIL discusses an offline
connection, the user will select the radio button “no” for the question “Will this PC have internet access during 6th
Gen TCM reprogramming and action requests?”. The user will then enter the PIN assigned to the USB dongle andselect “Unlock USB Dongle”. If the PIN is valid, the user will see a success response as shown in Figure 4, which
also includes the number of remaining signs left on the USB dongle (more information on USB dongle is containedin a later section of this SIL). Clicking “OK” to the pop-up in Figure 4 allows the user to proceed with performing theaction request on the 6th Gen TCM in the same way that 5th Gen TCMs action requests are performed.

Allison Cybersecurity USB Dongle: Checking and Recharging USB Dongle Signs:
Once a USB dongle has been provisioned, it has a limited number of “signs” that can be used to establish anauthenticated session with the TCM in order to perform action requests or reprogramming events when offline. Eachtime the USB dongle is used to enter an authenticated session, the number of signs remaining on the USB dongle
decreases by one. Once an authenticated session is opened, multiple action requests can be performed within thesame session without decreasing the number of signs. Only one reprogramming event is allowed per authentication
session, but in general, multiple parameters can be modified a single reprogramming event. (Changing activefunction packages cannot be changed on the same reprogramming event as other individual parameters.)
To check the number of signs remaining on the USB dongle, perform the following process:1. Insert USB dongle to PC’s USB port and ensure the white LED illuminates. If it does not illuminate, remove
and reinsert the USB dongle.
