Pinpoint Test E : The Traction Control System Cannot Be Disabled: Notes
Refer to Instrument Cluster for schematic and connector information.
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 IPC through the GWM over the HS-CAN3 to illuminate the stability-traction control disabled indicator (sliding car OFF icon). 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.
