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/stability assist indicator (sliding-car icon) in the Instrument Cluster (IC) will illuminate solidly.

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

The IC sends 5 volts to the traction control switch along circuit CCA15 (YE/GY). When the traction control switch is pressed, this voltage is sent through the switch and to ground along circuit GD134 (BK/VT). When the IC detects this ground, it sends a message to the PCM and the ABS module along the High Speed Controller Area Network (HS-CAN) bus that the driver has disabled the system.
