Traction light
 

Anyone have trouble with the traction coming on and the light coming on -- traction light and service engine!

I have managed to get rid of the traction light by disconnecting the battery and reconnecting it. Sometimes when you step on the gas and cause the wheels to spin caused the traction light to come on and there wasn't anything wrong with the system.
One thing to keep in mind , when you disconnect the battery you lose all programming seats, mirrors, radio and the vehicle will need to be driven a while ( 10-20 miles) before the computer relearns past driving habits related to engine performance. It may be a little inconvenient , but in my case it worked.
