I: C1093 - Traction Control Disable Switch Circuit Failure/the Traction Control System Cannot Be Disabled/Ena

Pinpoint Test I: DTC C1093 - Traction Control Disable Switch Circuit Failure/The Traction Control System Cannot Be Disabled/Enabled or the Traction Control Warning Indicator is Always On

Normal Operation
Traction control is controlled through the powertrain control module (PCM) by modulating the engine torque, this is achieved by regulating fuel and spark to the cylinders. When the PCM senses a traction control event is taking place, it sends the instrument cluster a message over the communication network to illuminate the traction control indicator or to flash the traction control indicator. The traction control indicator informs the driver that a traction control event is taking place, by flashing the indicator.

The traction control system can be disabled by pressing the traction control switch located on the instrument panel. When the system is disabled, the traction control system indicator in the instrument cluster, and on the traction control switch, will illuminate.

The instrument cluster sends 5 volts to the traction control switch along circuit CCA15 (YE/GY). When the traction control switch is pressed, this voltage is sent to ground through the switch and along circuit GD116 (BK/VT). The instrument cluster also provides voltage for the traction control switch illumination along circuit VLN04 (VT/GN). Ground for illumination is provided along circuit GD 116 (BK/VT).

Possible Causes
^ Circuit open
^ Circuit shorted
^ Hazard/PAD/traction switch
^ Instrument cluster
