    Your post has nothing to do with "PCM tuning". Please read the descriptive text in each forum banner to find out what is supposed to be posted there.

    Moved to the proper STS forum.

    The ignition system has nothing to do with ABS or TCS.

    Codes are meaningless without definitions.

    Every one of your codes has one thing in common; the EBCM (Electronic Brake Control Module) located at the bottom front LH corner of the powertrain cradle.

    The first thing I would do is remove the bottom air deflector panel and thoroughly inspect the wire harness and connector looking for damaged/broken wires and oxidation/corrosion on the connector pins and sockets.
