    yaw rate sensor is bad went under water
    is this a direct replacement or does new one have to be programmed by a dealership?
    any advice is appreciated

    It can be cleared and calibrated using a jumper wire. You need to find a service manual and look under brake control: vehicle stability control calibration. Or find someone that has posted zero point calibration after lift and alignment

    ok so i did the jumper wire blink test
    and i came up with 5 trouble codes

    1st-----31 = Center Airbag Sensor Assembly Malfunction
    which i assume is just caused by the other trouble codes being thrown "correct?"

    2nd--------35 = Seat Position Airbag Sensor Circuit Malfunction

    Occupant detection computer, under passenger seat. Said that the day she went under...just sayin.

    Hope you get this squared away. I would wager this takes care of a few of your codes.

    I thought for sure it was the yaw rate sensor as I vacumed it out of a puddle

    Its a black box maybe 3"X4"x1/2" thick mounted to the under side of the seat. Mine was toast after I went under. Fixed everything when I changed it.

    Can you get the actual codes from the vehicle with a scan tool?

    i know it has a problem when it detects wheel slip

    From the codes you have provided with out a scan tool to get actual codes, and without actualy touching the truck it looks like it will be your center airbag sensor assy. Going through the diag trouble code flow chart the only thing that all those codes have in common is the airbag ecu under your center console. I would start with that it is plug and go.

    For the yaw rate sensor try to clear the calibration and recalibrate before changing it.

    None of the codes relate to this ecu. if IGN 15A and IG1 10A fuse are ok it points to center airbag sensor
