Pinpoint Test R: The Traction Control Indicator Is Never/Always On (If Equipped)

Normal Operation

The traction control indicator informs the driver that a traction control event is taking place, by flashing the traction control indicator during the event. The traction control indicator illuminates constantly when a malfunction is detected in the traction control system, or if the traction control system is disabled by the operator. The ABS module monitors the traction control event and sends the Instrument Cluster (IC) a Controller Area Network (CAN) message to illuminate the traction control indicator.

This pinpoint test is intended to diagnose the following:

- ABS module
- IC
