Pinpoint Test K: DTC C1093 - Traction Control Disable Switch Circuit Failure/The Stability/Traction Control Switch Indicator is Inoperative
Refer to Vehicle/Diagrams, Instrument Cluster for schematic and connector information.

Normal Operation
The stability/traction assist system status is indicated by an indicator in the instrument cluster. The traction control switch is hard wired to the instrument cluster module. When the driver deactivates the traction assist system, the instrument cluster sends a message to the powertrain control module (PCM) and the anti-lock brake system (ABS) module over the high speed communication area (HS-CAN) bus. The traction assist system will remain deactivated until the driver pushes the switch again or until the ignition switch is cycled.

The instrument cluster sends a 5-volt reference voltage to the stability/traction control switch along circuit CCA15 (YE/GY). When the switch is pressed, the reference voltage is momentarily grounded through the switch along circuit GD116 (BK/VT). A failure in either of these 2 circuits or the switch itself will cause DTC C1093 to set.

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