vsc off/trac issue

[JCDM]

I searched in the forum and not found anything....

The issue is that the lights are coming on randomly, not every day.. this happen sometimes once in a week, i changed the gas cap, checking for error code and nothing. Restart the engine and the lights go. This happen sometimes once in a week.

Best regards

Juan

Your car has a pending code of some kind, which triggers the VSC/Traction OFF.
1) You need to have the code read from your car computer (ECM)
2) Depending on the code, you'll know which direction to go.

Mine had a P0442 code which ended being the charcoal canister and the fuel tank check valve:

You have an intermittent fault that is triggering a DTC in the Skid Control ECU, it goes out because the Skid Control ECU, much like the SRS ECU has a more forgiving retest/reset pattern than the MIL.

You need an ABS capable scantool to pull any possible History DTCs stored in the Skid Control ECU and/or check it when the lights are actually on.


This thread will help explain the difference between the various warning lights commonly asked on the forum.
