Normal Operation

The stability/traction control switch is hard wired to the Instrument Cluster (IC). Traction control system status is indicated by an indicator in the IC  . When the driver deactivates the traction control, the IC sends a message to the PCM and the ABS module over the High Speed Controller Area Network (HS-CAN) bus. The traction control system will remain deactivated until the driver pushes the switch again or until the ignition switch is cycled.

The IC  sends a 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).

• DTC C1093 (Traction Control Disable Switch Circuit Failure) - DTC C1093 will be set if the stability/traction control switch is pressed for more than 2 minutes during normal operation, is pressed at all during the IC  on-demand self test or if there is a short to ground on circuit CCA15 (YE/GY).

  This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• Stability/traction control switch
• IC
