Diagnostic Procedure

  1. If ABS warning light stays on, go to step  3. If ABS warning light does not illuminate, check fuse, light bulb and wiring. Repair or replace as necessary. If bulb is okay, diagnose combination meter (instrument panel). See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. If no problems were found, go to next step.
  2. Check ABS control relay. See SOLENOID RELAY SECTION  under ABS CONTROL RELAY under COMPONENT TESTS. Replace as necessary. If ABS control relay is okay, go to next step.
  3. Retrieve DTCs. See RETRIEVING DTCS  under DIAGNOSIS & TESTING. If DTC is present, perform appropriate test under DIAGNOSTIC TESTS. If DTC is not present, and ABS warning light goes off when short pin is removed, go to next step. If ABS warning light does not turn off, check for short circuit in wiring harness between ABS warning light, DLC1 and ABS ECU. Repair as necessary. See WIRING DIAGRAMS .
  4. Check ABS control relay. See SOLENOID RELAY SECTION  under ABS CONTROL RELAY under COMPONENT TESTS. Replace relay as necessary. If relay is okay, check for short circuit in wiring harness between DLC1 and ABS control relay. Repair as necessary. See WIRING DIAGRAMS .
