When the stability/traction control switch is pressed, ground is supplied to the Instrument Panel Cluster (IPC) to enable or disable the AdvanceTrac® with Roll Stability Control (RSC®) system. The IPC communicates the system status (on or off) to the ABS module via the High Speed Controller Area Network (HS-CAN). The AdvanceTrac® with Roll Stability Control (RSC®) system is automatically enabled when the ignition is cycled.

If a MyKey® restricted key is in use with the AdvanceTrac® always-on feature configured to "on", the traction control system cannot be disabled. An admin key must be used in order to enable and disable the traction control system.

The center stack switch assembly contains the PAD indicator, the traction control switch, and the hill descent switch (if equipped).
