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
Unlike the standard anti-lock control system, the traction control system and the AdvanceTrac® system can be deactivated (at the same time) by the driver through the stability/traction control switch. The switch is hardwired to the IC and when pressed sends a ground signal to the IC. The IC then sends a message over the HS-CAN bus indicating that the driver has requested that the system be deactivated and illuminates the stability/traction control indicator (sliding-car OFF icon). After receiving this message, the ABS module and PCM will ignore any stability or traction events until the driver presses the switch again or 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 MY KEY SETTING will display in the IC message center. For information about MyKey™, refer to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) .
