Various views of a "MaxScan OE509" – a fairly typical onboard diagnostics (OBD) scanner, 2015. On-board diagnostics (OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that may increase the ...
OBD-II PIDs. 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.
To ensure high quality in the Computer Command Control system, it will be given a final check at the end of the assembly line. Here the completely assembled vehicle will be tested by connecting the computer to a test computer. This will significantly improve GM's ability to catch anything wrong with the system or the car's engine." [1] [2] [3]
It is the only one of GM's Latin-letter platforms still in use. The eventual consolidated successor to the Gamma II, G2XX, E2XX, D2XX, P2XX, PATAC K, U IV, GM4200, and GEM platforms. The eventual consolidated successor to the Alpha and Omega platforms. Slated to underpin all RWD GM vehicles by 2025.

ELM327. The ELM327 is a programmed microcontroller produced for translating the on-board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors. The original ELM327 was implemented on the PIC18F2480 microcontroller from ...
In the US 49/563.5 regulatory framework, Event data recorder is defined as a . a device or function in a vehicle that records the vehicle's dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval after the crash event.
