    That's not your ABS, that's your infotainment system.

    It looks like VCDS has the wrong chassis type at that point. Were you into another car with your VCDS just prior to that? Or did you go...

    OK, good.


    Yes, OCJ would be the index or color code. These terms are used somewhat interchangeably. If you were ordering, for example, an interior trim price, then that suffix to the part...

    Worth trying (and doesn't cost anything!) but since there's no fault for "ECU Unauthorized", I don't have high hopes for it.

    Yup. There is one and only one coding acceptable to these modules and it's determined by the module's "index" or "color code", which in turn is determined by the parameter set in the module, which...

    I think the ECU queries the immo/cluster ("Is it OK for me to start/run?" and the immo/cluster responds to that query, but I'm not 100% certain.

    Scratching head here.

    Comms with Engine are OK, but Engine Start is not permitted. Makes sense since neither variable nor fixed code is authorized.

    Yes, log was done correctly. :)

    Idle values look good, but they don't tell us a whole lot. Even a failing MAF will usually show "OK" values at idle.

    Max value is 46.67 g/s, but that was at...

    I guess the first thing I would do is to pull the connector(s) from ECU and check the condition of the pins. There should be no water in there, and no corrosion.

    The old Login function simply doesn't exist on modules that use the UDS protocol, which your ECU does.

    You should probably tell the BCM that there's a CCS installed too (Byte 17).
