Pinpoint Test E : The Traction Control System Cannot Be Disabled: Notes

Refer to Instrument Cluster for schematic and connector information.

NOTE: This test requires the use of at least 2 keys programmed to the vehicle, one admin key and one restricted key.

Normal Operation and Fault Conditions

The stability-traction control disabled indicator (sliding car OFF icon) in the IPC provides traction control system status to the driver. When the driver deactivates the traction control, the IPC sends a message to the GWM over the HS-CAN3 indicating the driver has requested the traction control to be disabled. The GWM relays this message to the ABS module over the HS-CAN2. The ABS module continues to monitor for excessive wheel spin, but no longer takes any action when a traction event is detected.

The ABS module then sends a message to the GWM over the HS-CAN2 to illuminate the stability-traction control disabled indicator (sliding car OFF icon). The GWM relays this message to the IPC over the HS-CAN3. The IPC responds by illuminating the stability-traction control disabled indicator (sliding car OFF icon). The traction control system remains deactivated until the driver changes the traction control state in the message center or until the ignition is cycled.

If equipped, MyKey ® allows users to configure traction control to be either always on or selectable. If a MyKey ® restricted key is in use with the AdvanceTrac ® always on feature configured to "on", the traction control system cannot be disabled. An admin key must be used to enable and disable the traction control system.

Possible Causes

MyKey ® restricted key in use
Network communication concern
IPC concern
GWM concern
Message center concern
