    looking for new suggestions. the lights are on while driving, but no check engine light. mechanic plugged in the computer and there are no error codes popping up. someone suggested the swapping out the brake light switch. I replaced it but the lights stay on. thanks for any recommendations

    VSC and TRAC lights come on when you start the engine, or only come on after the vehicle begins to move? I'm thinking possible ABS sensor problem. I had a shock absorber break one time (Gen3) and it speared the ABS wire, partially severing it. I did get an ABS error with that, as I recall.

    Maybe a ZPC would fix it.
    Zero point calibration.
    Really easy to diy.

    Not sure if this site has detailed info on it, i dont spend much time here.
