OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
The development of an ECU involves both hardware and software required to perform the functions expected from that particular module. Automotive ECU's are being developed following the V-model. [ 1 ] Recently the trend is to dedicate a significant amount of time and effort to develop safe modules by following standards like ISO 26262 . [ 5 ]
This interface was made in different varieties and changed with power train control modules (aka PCM, ECM, ECU). Different versions had slight differences in pin-outs and baud rates. Earlier versions used a 160 baud rate, while later versions went up to 8192 baud and used bi-directional communications to the PCM.

It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control Module (BCM), for a total of three separate computers. These automotive computers are generally very reliable.
An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.

[2] [3] NVTCS equipped Nissan engines do not have as high of engine speeds as VTEC equipped engines so NVTCS is simpler, quieter, and requires no special maintenance. [ citation needed ] Some Nissan engines only have N-VTC on the intake cam such as the GA16DE, QG16/18, SR20DE/DET (S14-15) or RB25DE/DET (R33-R34 GTS/GTS-T, GT/GTT) while others ...
