Diagnosis & Repair

  1. If light is illuminated constantly, go to step  7. If light does not illuminate, check GAUGE fuse, ABS warning light bulb, instrument cluster and wiring. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT. If components are okay, go to next step.
  2. Remove ABS solenoid relay from engine compartment No. 2 relay block. Relay block is located on left side of engine compartment. Continuity should exist between relay terminals No. 2 and 3. See Figure. Continuity should not exist between relay terminals No. 1 and 3. Measure resistance between relay terminals No. 4 and 6. Resistance should be about 80 ohms. If all preceding tests are as specified, go to next step. If any preceding test is not as specified, replace ABS solenoid relay.
  3. Using jumper wires, apply battery voltage to relay terminal No. 4 and ground relay terminal 6. See Figure. Check for continuity between ABS solenoid relay terminals. Continuity should exist between relay terminals No. 1 and 3. Continuity should not exist between relay terminals No. 2 and 3. If all preceding tests are as specified, go to next step. If any preceding tests are not as specified, replace ABS solenoid relay.
  4. Connect positive lead of ohmmeter to ABS solenoid relay terminal No. 5 and negative lead to terminal No. 3. Check for continuity. If continuity exists, go to step  6. If continuity does not exist, go to next step.
  5. Connect positive lead of ohmmeter to ABS solenoid relay terminal No. 3 and negative lead to terminal No. 5. Check for continuity. If continuity does not exist, replace ABS solenoid relay. If continuity exists, go to next step.
  6. Check for open in wire harness between ground, ABS solenoid relay and Data Link Connector No. 1 (DLC1). DLC1 is located on left side of engine compartment, near junction block.
  7. Retrieve Diagnostic Trouble Codes (DTC). See RETRIEVING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. If any DTCs are set, repair appropriate DTC. If no DTCs are set, remove short pin from DLC1. See Figure. If ABS warning light turns off, go to next step. If ABS warning light stays on, check for short in Black/Yellow wire between terminal No. 11 at ABS ECU A22 connector, DLC1 and ABS warning light. See WIRING DIAGRAMS .
  8. Check ABS solenoid relay. Go to step  2. Replace relay as necessary. ABS solenoid relay is okay, check for short in Violet wire between ABS solenoid relay and DLC1.
