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.

    OBD2 MG5 PFL LR

    Can anyone help? Bought a NEXAS OBD2 dongle, and using Car Scanner it connects to the dongle ok but it keeps saying can't connect to the car ECU. It goes round trying every protocol and failing. Maybe I have the wrong profile? I set it to MG5 2021-22. See screenshot. Thanks P

    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...
