Test I: the Traction Control Switch Indicator Is Never/Always on

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

Refer to Vehicle/Diagrams, Vehicle Dynamic Systems for schematic and connector information.

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
