Test H: DTC C1093 - Traction Control Disable Switch Circuit Failure and/or the Traction Control System Cannot be Disabled

Refer to Vehicle/Diagrams, Instrument Cluster for schematic and connector information.

Normal Operation
Engine torque modulation is achieved by regulating fuel and spark to the cylinders. The traction control system operates using the anti-lock brake system (ABS) module to interact with the powertrain control module (PCM) to reduce engine torque and apply the brakes if the wheels lose traction and begin to spin during acceleration.

The instrument cluster circuit 1412 (WH/PK) monitors for a ground (change of state). When the traction control switch is pressed, a 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
- Anti-lock brake system (ABS) module
- Instrument cluster
