Normal Operation and Fault Conditions

The traction control switch is used to switch the AdvanceTrac features (traction control, ESC and RSC) 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-CAN 3 and the GWM relays this message to the ABS module over the HS-CAN 2. The ABS module takes the necessary action depending on the switch inputs and traction control message. For additional information on disabling AdvanceTrac, refer to  Anti-Lock Brake System (ABS) and Stability Control  , Description and Operation.
