Stability/Traction Control Switch

The stability/traction control switch provides the driver with the ability to disable only the traction control feature. Anti-lock control, ESC  and RSC®  systems will remain functional. The switch is hardwired to the ABS module. When the stability/traction control switch is pressed, a ground signal is sent to the ABS module. The ABS module then sends a message over the HS-CAN  bus to the IC  indicating that the driver has requested that the system be deactivated and the IC  illuminates the stability/traction control indicator (sliding-car icon). The ABS module and the PCM will then ignore any traction events until the driver presses the switch again, the ignition key is cycled or the vehicle speed reaches or exceeds 70 km/h (43 mph). Once the vehicle speed reaches or exceeds 70 km/h (43 mph), the traction control system will reactivate but the indicator will remain illuminated.

The ESC  system cannot be disabled when a MyKey™-restricted key is in use that has the AdvanceTrac® always-on feature configured "on". If an attempt is made to disable the ESC  system while a MyKey™-restricted key is in use, ADVTRAC ON MY KEY SETTING will display in the IC  message center.
