Normal Operation

The stability/traction control switch is a momentary contact switch and is part of the liftgate release and hazard switch assembly. When the switch is pressed, the ABS module is momentarily grounded through the switch. The ABS module then sends a message to the PCM along the High Speed Controller Area Network (HS-CAN) to disable the traction control function. The ABS module also sends a message over the HS-CAN to the Instrument Cluster (IC) to illuminate the stability/traction control disabled indicator (sliding-car OFF icon).

If a MyKey® restricted key is in use that has the AdvanceTrac® always-on feature configured "on", the stability/traction control system cannot be disabled.

This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• Stability/traction control switch
• ABS module
