### Circuit Description

The EBTCM goes through a self-test when the ignition is first turned to RUN. During this test, the EBTCM grounds both the ANTILOCK and the TRACTION OFF indicators for 2-4 seconds. This acts as a bulb test for the indicators.

#### Traction Control Switch

The traction control switch allows the driver to select the traction control mode (ON/OFF). When the traction control system is turned OFF, the TRACTION OFF indicator remains illuminated.

### Diagnostic Aids

The following conditions may cause the TRACTION OFF indicator to be ON with no DTCs set:

• | The traction control system is turned OFF by the driver.

• | A short to ground in either of the following circuits:

- | CKT 1571

- | CKT 1572

• | A malfunctioning traction control switch

• | A malfunctioning EBTCM

Inspect for PCM DTCs.

When the vehicle is equipped with traction control, any symptom that illuminates the ANTILOCK indicator also illuminates the TRACTION OFF indicator. Follow the ANTILOCK indicator diagnosis when both indicators are illuminated and no diagnostic trouble codes are set.
