    U0212 Code

    Good morning.

    For the past 3 weeks, my traction control lights are on, sometimes intermittent, sometimes stay on all day.

    When I'm towing, the light goes off completely; when I check the tuner, the U0212 is the only code that I got, and I already changed the batteries.

    Checked for losing connections, changed sensors on the rear differential, any suggestions/advice appreciated / this light with the sound is driving me crazy.

    Also, I cleaned the DTC and come back immediately.

    Re: U0212 Code

    Is this a U0212 or a U0121?

    The U0212 is a CAN bus error for loss of communication with the Steering Column Control Module.

    U0121 can be related to ABS or TIPM.

    You can carefully check the harness connections to the TIPM.

    Otherwise, it could be the ABS module.
