    Had my left front wheel bearing replaced last week and suddenly I'm getting the ((!)) ABS VSC light anytime my RIGHT front wheel goes over even a tiny bump. My OBD reader was throwing a bunch of brake codes but I cleared them and ran them again and nothing came up. I know my brake actuator is starting to bleed off a bit but I don't know if that's related. 12v is reading fine.

    If needed, here were the codes. Either weeks ago I had the brakes bled and a pin unstuck.

    C0200- RF sensor

    C0205 - LF sensor

    C1235 - LF debris

    C1245 - Foreign Object Attached on Tip of Front Speed Sensor RH (Right Front)" or a signal disturbance from the right front wheel speed sensor

    C1253 - Hydro pump motor relay malfunction

    C1256 - Low accumulator pressure

    Isn't the person who did your wheelbearing responsible for this situation? Or at least as a first step can you take it back to them and communicate this information?

    I would take it back to them and have them check the wiring harness from the ABS speed sensor at the hub/bearing assembly and make sure it's not damaged or any wires frayed. If it's intermittent, perhaps something minor and they should replace or fix it.
