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 is hard-wired to the instrument cluster module. The instrument cluster module communicates the stability/traction control switch status to the ABS module via the HS-CAN bus.
The stability/traction control switch allows the driver to control use of the ESC/RSC and traction control system. This is independent of the ABS function, which cannot be switched OFF by the driver. The ESC/RSC and traction control system status is indicated by a light in the stability/traction control switch. When the stability/traction control switch is set to OFF, the system is disabled at and below 32 km/h (20 mph). The system will automatically restore to full functionality every time the vehicle speed exceeds 32 km/h (20 mph) or when the ignition switch is cycled from OFF to RUN. However, the stability/traction control switch OFF indicator remains illuminated until the switch is pressed a second time. The ABS function continues to work as designed unless the yellow ABS warning indicator is illuminated. Normal braking function always occurs, unless the red brake warning indicator is illuminated.
