I followed the instructions in the owners manual and the light is still on. What is the next step? Does the relay go out?

Just before the warning light came on I was driving on a rough patch of roadway with pot holes, and uneven road surface of ashpalt and cement.

Thanks,

Mark

If the light is on at all times, even after several key cycles there is more than likely a fault related code stored in the EBCM (Electronic Brake Control Module). It would need scan tool diagnostics to determine what the code is, and a course of action.

Check the attached guide on check engine light scan, it is the same process for the Traction control system, which is usually tied to the ABS system. Also attached is a video on the subject that will may help

I also attached the wiring diagram for the ABS/Traction Control System

Check the guide/video and diagram and get back to us.

Sounds like a misfire, go to autozone and have it scanned and bring the trouble codes back to me for further diagnosis

When I start my car, the service engine light and my trac low light comes on. You can also smell gas and it shakes when I drive it. What is wrong with my car?

If the lights are coming on, you need to have the computer scanned. Many things can cause what you described. If the light is on, chances are there will be a code stored in the computer that will identify where the problem is coming from. Most nationally recognized parts stores will do it for free. Have it done and let me know what you find.
