Thanks.When the TCL Off light turns on in this model it is indicating an issue within the ABS system.... generally it is as simple as a wheel speed sensor, but on occasion it can become more complex (throttle body, solenoids etc).Are you able to get the ABS system scanned to see what fault numbers are causing it to disable the traction system?

no, cannot get ABS system scanned
Expert:  Doug replied 7 months ago.
Hmm, unfortunately that puts us in a bit of a tough position as there are literally dozens of possible causes for that light to go on, there isn't any one thing that you could speculate with any reliability to blame. Even the most common (wheel speed sensors) would only narrow you down to one of four parts if you were wanting to guess at it... and that would get expense for certain.Since we can't get it scanned, storing (or more to the point, losing) the code is not as critical... have you unhooked the negative battery terminal for 30 seconds and reconnected to see if the fault returns? On the ABS/TCL system it does not permanently store the codes (no battery, no codes), so we could do that to see if it was a hard fault or a one time event. Likewise if it stays off then comes on while driving (versus key on, versus key on engine one but not driving) that could help indicate a more narrow area of concern.
