Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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 stability/traction control OFF indicator (sliding-car icon). The ABS module and the PCM then ignores any traction events until the driver presses the switch again or until the ignition key is cycled.
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. For additional information about MyKey™, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) - HYBRID article.
