Pinpoint Test O: The Traction Control System Is Inoperative, Cannot Be Disabled Or Enabled Using The Traction Control Switch
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.
