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 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 sliding-car icon. The ABS module and the PCM then ignores 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 re-activates but the indicator remains illuminated.

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