On-board diagnostics. 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 ...
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 .
A distinctive design feature is the "AirBump" panels on the car's sides, designed to protect the vehicle from damage in car parks. The Citroën Cactus Concept, presented at the 2013 Frankfurt Motor Show, previewed the production version. [1] The C4 Cactus was presented at the 2014 Geneva Motor Show.
Automatic, the company behind an on-board diagnostics (OBD-II) dongle for cars, announced that it’s shutting down due to COVID-19. The company says customers can toss (or recycle) its adapters ...
Unified Diagnostic Services ( UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [ 1] It is derived from ISO 14230-3 ( KWP2000) and the now obsolete ISO 15765 -3 (Diagnostic Communication over Controller Area Network (DoCAN) [ 2] ).
