my traction off light keeps going off and on what is it
I just recently purchased this car and in the upper left the traction off light keeps going off and on and now the check engine light is on are they connected ?
Could be related as the TCM (trans control) is tied to the ECM/PCM which is engine light. It's time to take this in for a dealer scan. Obviously there is an intermittent problem with some part of the traction control system which may be linked to or causing the MIL light to illuminate.
The traction light coming on is usually cause be a bad ABS sensor, or sometimes a bad alternator. If it's not charging enough, the light will come on due to a low system voltage.
I had the same exact problem with this. First the traction light would go on and off, then the abs light came on and stayed on. We took it in and got a new abs sensor put in, and both lights dont come on anymore. They said we didnt need it fixed cuz no matter what regular brakes work. The part was really expensive to fix. For a new one your looking at 1,000!!! We got a used one and only spent 500. We fixed it cuz the light was annoying.
