    Replaced tie rods. Drove car to alignment shop. Traction control light is now stagnant. Alignment was performed. Traction control light is still stagnant. Fault code C 1290.

    How do I reset traction control light.

    Check connections to wheel sensors.

    The code is about the steering angle zero point. First make sure the alignment is reasonable: is the steering wheel well centered when driving straight ahead, 22 mph or more?

    If that's ok, do a clear and relearn of the yaw rate and acceleration sensor. The steering angle zero point ought to be captured correctly after that. If it still can't be, there could be a contributing problem with the wheel speed sensors (the ECU won't believe you're driving straight, if it thinks the wheels are turning different speeds).

    I know that the aliment shop can set the steering wheel straight.
