ABS/TCS Circuit Schematic:

CIRCUIT DESCRIPTION
When the ignition is first turned to RUN, the Electronic Brake/Traction Control Module (EBCM/EBTCM) goes through a self-test. During this test, the EBCM grounds both the ANTILOCK and TRACTION OFF indicators for approximately 2 to 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
Possible Causes:
- Open fuse.
- Open in CKT 39, 150, 1451, 1571 or 1572.
- Open bulb.
- Malfunctioning traction control switch.

When the vehicle is equipped with traction control, any symptom which lights the ANTILOCK indicator also lights the TRACTION OFF indicator. Therefore, when both indicators are lit, follow ANTILOCK indicator diagnosis when no diagnostic trouble codes are set.
