obd 2 pinout for GM cars
A SourceForge project that provides a GUI for controlling ELM327 devices. Versions available for Windows and Linux. PC Scan Tool Some assorted bits of OBD.
Should be suitable for most modern GM cars - Buick, Cadillac, Chevrolet, Daewoo
GMC, Holden, Opel, Vauxhall.
GMC, Holden, Opel, Vauxhall.
Most GM cars produced in 1996-2003 use J1850-VPW interface. GM cars produced in 2003-2006 use J1850-VPW interface or CAN. Most cars produced after 2006 are equipped with CAN bus.
