Diagnosis & Repair

  1. If ABS warning light is illuminated constantly, go to step  8. If ABS warning 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. Ensure ignition is off. Remove ABS solenoid relay from engine compartment No. 6 relay block. No. 6 relay block is located on left side of engine compartment. Using an ohmmeter, check for continuity between ABS solenoid relay terminals. Continuity should exist between terminals No. 2 and 3, and should not exist between terminals No. 1 and 3. See Figure.
  3. Check for resistance between terminals No. 4 and 6. Resistance should be about 49-134 ohms. If all preceding tests are as specified, go to next step. If any preceding tests are not as specified, replace ABS solenoid relay.
  4. Apply battery voltage and ground between ABS solenoid terminals No. 4 and 6. Using an ohmmeter, check for continuity between ABS solenoid relay terminals. Continuity should exist between terminals No. 1 and 3, and should not exist between terminals No. 2 and 3. See Figure. If all preceding tests are as specified, go to next step. If any preceding tests are not as specified, replace ABS solenoid relay.
  5. 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  7. If continuity does not exist, go to next step.
  6. 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.
  7. Check for open in Violet wire between ABS solenoid relay and Data Link Connector No. 1 (DLC1). DLC1 is located in left side of engine compartment, next to strut tower. See WIRING DIAGRAMS .
  8. Retrieve DTC. See RETRIEVING DIAGNOSTIC TROUBLE CODES  under DIAGNOSIS & TESTING. If DTCs are stored, repair appropriate DTC. If no DTCs are stored, 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 Blue/White wire between ABS ECU connector A24, DLC1 and ABS warning light. See WIRING DIAGRAMS .
  9. Check ABS solenoid relay. Go to step  2. Replace as necessary. If ABS solenoid relay is okay, check for short in Violet wire between ABS solenoid relay and Data Link Connector No. 1 (DLC1). DLC1 is located in left side of engine compartment, next to strut tower. See WIRING DIAGRAMS .
