obd2

On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or "idiot light" if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow a person to rapidly identify and remedy malfunctions within the vehicle.

    Has anyone come across a compatible OBD2 scanner for the 2022 ZS? I had the dreaded "Vehicle Control System Fault" last night while at a charger which was fixed by the AA clearing the codes, so thought it best to have one to clear the codes my self if it ever happens again. I bought a cheapo...

    Compatible OBD2 scanner?

    After the refuelling issue a couple of days ago I borrowed an Ancel ODB2 scanner/reader diagnostic tool, but it's fairly extensive knowledge of manufacturer/vehicle specific codes doesn't extend to SAIC/MG and so I'll only be able to do generic ODB2. Has anyone come across an ODB2...

    Plugging into the OBD2 port???

    Very interesting info seems to be obtained from the OBD2 port on the ZS, however, is there anything that could be damaged by plugging in and if so, could MG use that action as a way to wriggle out of a warranty claim? If the answers are both negative, what is the best device to purchase to use...
