I got this after changing air filter, however this was due to I forgot to clip in connector on top of air filter cover.
First thing I noticed was that the engine was idling rough, to which I saw the the engine and Traction control lights on with blinking "TSC off" light.
Of course I remembered what I did and clipped the connector together. but this did not turn off the lights.
To turn them off:
Hold the Traction control off switch in.(located by the mirror controls),
Turn key to on position(do not start engine) let car go through POST(Power On Self Test).
If all is well all light should go out.

If they stay on you may actually have an issue.

Hope this helps
Is this supposed to work? It didn't for me. I'd rather not have to just unplug the battery, that would just mean I'd have to redo all my radio stations and clock, plus its raining outside.
