obd

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.

    Best OBD reader / software / app for MG4?

    Hi there, What's the best OBD reader and app to use on an MG4? I've got a Carly for my other car (a Toyota) and it's really useful for checking codes and turning certain functions on/off. I'd like the same for my MG4 but Carly doesn't do MGs. Any/all suggestions welcome. Thanks!

    OBD readers

    Has anybody found an OBD reader and an accompanying app suitable for MG5s? As well as reading general faults, I'd be interested in interrogating the battery state, in a similar way to Leaf-Spy. The ones I've investigated don't inspire confidence.
