PINPOINT TEST M : The Traction Control System Cannot Be Disabled: Notes

Diagnostic Overview 

The Traction Control System Cannot Be Disabled 

Refer to Instrument Cluster for schematic and connector information.

Normal Operation and Fault Conditions 

Traction control system status is relayed to the driver by the stability-traction control disabled indicator (sliding car OFF icon) in the IPC. When the driver deactivates the traction control, the IPC sends a message to the ABS module over the HS-CAN. The ABS module deactivates the traction control system and sends a message back to the IPC to illuminate the 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 switch 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 in order to enable and disable the traction control system.
