Normal Operation
Traction control system status is shown by an indicator in the Instrument Panel Cluster (IPC). When the driver deactivates the traction control, the IPC sends a message to the ABS module over the High Speed Controller Area Network (HS-CAN). The ABS module deactivates the traction control system and sends a message to the IPC to illuminate the stability/traction control indicator (sliding car icon) OFF light. 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.
This pinpoint test is intended to diagnose the following:
- Communication concern
- IPC
