    Tire pressure light and DSC light is on. I've changed all the wheel speed sensors and also replaced the ABS/DSC pump (I'm not sure if the pump needs to be programmed by the dealership). Speedo still doesn't work. I've checked all the fuses and they're all fine. I've also done the ECU reset and still no luck.

    Before I take it to Best, I wanted to make sure I haven't overlooked any steps to try and correct it. Any recommendations are appreciated, but I'm guessing my next step is taking it to an expert.

    Call John in the Morning, he is not adverse to giving advice. My guess would be the computer has to have the secret handshake done. Like I said justa guess.

    Check the ABS harness where it comes through the firewall to be sure it hasn't worn through the insulation. That is what was wrong with Blake's car that caused the same lights and electrical gremlins.

    It could also be the BCM. Check under the carpet on the passenger side to see if it has gotten wet.
