Pinpoint Test F: The Stability/Traction Control System is Inoperative or Cannot be Disabled

Refer to Wiring Diagram Set 42, Instrument Cluster for schematic and connector information. Diagrams By Number

Normal Operation

The stability/traction control switch is a normally open switch. When the switch is pressed, the Instrument Cluster (IC) senses ground through the switch and sends a message to the ABS module along the High Speed Controller Area Network (HS-CAN) bus to disable the stability/traction control system. The IC will also illuminate the traction control message center indicator.

The IC is connected to the stability/traction control switch along circuit CCA15 (YE/GY) and the switch is connected to ground along circuit GD133 (BK).

- DTC C2775 (TC/AYC ON/OFF Switch Stuck Failure) - If the IC senses a short to ground on stability/traction control switch circuit, if the stability/traction control switch is pressed for longer than 30 seconds, or if the stability/traction control switch is pressed during the on-demand self test, DTC C2775 will be set.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Stability/traction control switch
- IC
