## 面白点1 
Diag規格の面白いところは、ISO OSI参照モデルに基づいた整理をしようとしているところです。

Table 1 — Legislated emissions-related OBD/WWH -OBD diagnostic specifications applicable to the OSI layers
 ![15031-5.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/51423/11f00c6b-ec1b-9fa1-eeef-f6104be37d94.png)

OSI参照モデルの資料を作り始める（作業中）

https://qiita.com/kaizen_nagoya/items/26e1451ef4981c46b3be

## 面白点2
Ethernet, TCP/IPでも、Presentation層は規定がほとんどないのに対して、
Diagでは、SAEが規定していて、それをISO規格でNormative Referenceしている点です。

また、その仕様をDigital Annexとして本体規格の付録として体系化している点です。

Digital Annex of E/E Diagnostic Test Modes SAE J1979-DA 2011 Word count。docker(153) 何か失敗したかもしれない１日目。英語(51)

https://qiita.com/kaizen_nagoya/items/3bac8d88cc8d09fb92cc


## 面白点3

トラックの規格はSAEを、国際規格でも参照している。
アメリカがPick up Trackが流行りだということは知っていた。

映画、Stan By Meの回想シーンも　pick Up Trackで始まる。

SAE 規格を読み始めて

# 3   Terms, definitions, and abbreviated terms

## 3.1   Terms and definitions

>For the purposes of this document, the terms and definitions given in ISO 14229-2, ISO 14230-2, ISO 15031-2, and ISO 15765-2 and the following apply.

### 3.1.1 absolute throttle position sensor
value intended to represent the throttle opening
Note 1 to entry: For systems where the output is proportional to the input voltage, this value is the percent of maximum input signal. For systems where the output is inversely proportional to the input voltage, this value is 100 % minus the percent of maximum input signal. Throttle position at idle usually indicates greater than 0 % and throttle position at wide open throttle usually indicates less than 100 %.
### 3.1.2 bank
土手
specific group of cylinders sharing a common control sensor
共通制御センサーを共有するシリンダの特定グループ
Note 1 to entry: Bank 1 always contains cylinder number 1 and bank 2 the opposite bank.
Note 2 to entry: If there is only one bank, the DTCs for bank #1 DTCs are used and the word bank may be omitted. 
With a single “bank” system utilizing multiple sensors, bank #1 DTCs are used in identifying the sensors as #1, #2, and #3 in order as they move further away from the cylinder.
### 3.1.3 base fuel schedule
fuel calibration schedule programmed into the powertrain control module or PROM when manufactured or when updated by an off-board source, prior to any learned on-board correction
### 3.1.4 calculated load value
<spark ignition vehicles> typically an indication of the current airflow divided by peak airflow at wide open throttle as a function of rpm, where airflow is corrected for altitude and ambient temperature
Note 1 to entry: Both spark ignition and compression ignition vehicles can use an alternate definition that substitutes engine torque in place of airflow in the calculation.
Note 2 to entry: This definition provides a number (without unit) and provides the service technician with an indication of the percent engine capacity that is being used.
### 3.1.5 client
function that is part of the tester and that makes use of the diagnostic services
Note 1 to entry: A tester normally makes use of other functions such as database management, specific interpretation, and man-machine interface.
### 3.1.6 continuous monitoring
sampling at a rate no fewer than two samples per second
Note 1 to entry: If, for control purposes, a computer input is sampled less frequently, the signal of the component may instead be evaluated each time sampling occurs.
### 3.1.7 convention, Cvt
column integrated in each message table which marks each parameter included
Note 1 to entry: The following conventions are used: C = Conditional: the parameter marked “C” in a request/response message is present only under a condition specified in the bottom row of the message table; M = Mandatory: the parameter marked “M” in a request/response message table is always present; U = User (optional): the parameter marked “U” in a request/response message table is supplied depending on dynamic usage by the manufacturer. The convention recommends a mnemonic, which might be used for implementation. In no case is the specified mnemonic ever a mandatory requirement for any implementation.
### 3.1.8 electronic control unit, ECU
generic term for any electronic control unit
### 3.1.9 emissions-related DTC
DTC which is set when a malfunction causes vehicle emissions to exceed legislated emission thresholds or is otherwise required to be set as specified by on-board diagnostics legislation (e.g. disables another part of the diagnostic system)
Note 1 to entry: Normally, the malfunction indicator (MI) is illuminated at the same time as the emissions-related DTC is set. The determination of which DTCs are emissions-related is made by the vehicle manufacturer for each vehicle, as specified by on-board diagnostic legislation.
### 3.1.10 fuel trim, FT
feedback adjustments to the base fuel schedule
Note 1 to entry: Short-term fuel trim refers to dynamic or instantaneous adjustments. Long-term fuel trim refers to much more gradual adjustments to the fuel calibration schedule than short-term trim adjustments. These long-term adjustments compensate for vehicle differences and gradual changes that occur over time.
### 3.1.11 negative numbers
signed binary, the most significant bit (MSB) of the binary number used to indicate positive (0)/negative (1)
Note 1 to entry: 2's complement: negative numbers are represented by complementing the binary number and then adding 1.
EXAMPLE:–0,99 = 800116 = 1000 0000 0000 00012
0 = 000016 = 0000 0000 0000 00002
+0,99 = 7FFF16 = 0111 1111 1111 11112
Note 2 to entry: (–0,99) + (+0,99) = 0.
### 3.1.12 number
expressed by this symbol “#”
### 3.1.13 P2, P3 timing parameter
application timing parameters for the ECU(s) and the external test equipment
### 3.1.14 P2CAN_min timing parameter
CAN application timing parameter with the minimum value for the ECU(s) and the external test equipment to start the response message
### 3.1.15 P2CAN_max timing parameter
CAN application timing parameter with the maximum value for the ECU(s) and the external test equipment to indicate a response message
### 3.1.16 P2reload timing parameter
CAN application timing parameter with the maximum value (P2CAN_max) for external test equipment only
### 3.1.17 server
function that is part of an ECU that provides the diagnostic services
Note 1 to entry: This part of ISO 15031 differentiates between the server, i.e. the function, and the electronic control unit so that it remains independent from the implementation.
### 3.1.18 service
information exchange initiated by a client (external test equipment) in order to require diagnostic information from a server (ECU) and/or to modify its behavior for diagnostic purposes
Note 1 to entry: This is also the equivalent of test mode or mode.
