Test J: The Traction Control Switch Indicator Is Never/Always On

Pinpoint Test J: The Traction Control Switch Indicator is Never/Always On

Normal Operation
The instrument cluster circuit 1412 (WH/PK) monitors for a ground (change of state). When the traction control switch is pressed momentary ground occurs through circuit 1205 (BK). The instrument cluster then sends a voltage to the traction control switch through circuit 939 (VT) illuminating the traction control switch and disabling the system.

Possible Causes
^ Circuit open
^ Circuit shorted
^ Traction control switch
^ Instrument cluster
