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.
Pinpoint Test O: The Traction Control System Is Inoperative, Cannot Be Disabled Or Enabled Using The Traction Control Switch: Notes
Refer to INSTRUMENT CLUSTER for schematic and connector information.
Normal Operation and Fault Conditions
The traction control switch is used to switch the traction control system on or off. When the traction control switch is pressed, the IPC receives a ground signal from the switch and illuminates the stability-traction control OFF indicator. The IPC sends a traction control switch message to the GWM over the HS-CAN3 and the GWM relays this message to the ABS module over the HS-CAN2. The ABS module takes the necessary action depending on the switch inputs and traction control message.
