Pinpoint Test C - Wheel Sensor & Circuit

  1. DTC 41: Check Right Front Wheel Sensor Circuits

    Remove cover from HCU. See COMPONENT LOCATIONS  . Disconnect jumper harness from ABS control module. Check continuity between ground and ABS control module 15-pin harness connector terminals No. 8 (Yellow/Red wire) and No. 14 (Yellow/Black wire). See Fig 1 . If continuity does not exist, go to next step. If continuity exists, repair/replace jumper harness, repair circuits No. 514 (Yellow/Red wire) or No. 516 (Yellow/Black wire) between ABS control module and right front wheel sensor or replace right front wheel sensor.

  2. Check Right Front Wheel Sensor Air Gap

    Remove right front wheel. Inspect for damaged wheel sensor or toothed indicator ring. Check for objects sticking to wheel sensor or toothed indicator ring. Check for excessive wheel bearing end play. Check air gap between wheel sensor and toothed indicator ring. Air gap should be .019-.037" (.50-.95 mm). If all conditions are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If all conditions are not okay, repair/replace components as necessary.

  3. DTC 42: Check Right Rear Wheel Sensor Circuits

    Remove cover from HCU. See COMPONENT LOCATIONS  . Disconnect jumper harness from ABS control module. Check continuity between ground and ABS control module 15-pin harness connector terminals No. 6 (Tan/Light Green wire) and No. 7 (Brown wire). See Fig 1 . If continuity does not exist, go to next step. If continuity exists, repair/replace jumper harness, repair circuits No. 492 (Brown wire) or No. 494 (Tan/Light Green wire) between ABS control module and right rear wheel sensor or replace right rear wheel sensor.

  4. Check Right Rear Wheel Sensor Air Gap

    Remove right rear wheel. Inspect for damaged wheel sensor or toothed indicator ring. Check for objects sticking to wheel sensor or toothed indicator ring. Check for excessive axle bearing end play. Check air gap between wheel sensor and toothed indicator ring. Air gap should be .023-.063" (.60-1.60 mm). If all conditions are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If all conditions are not okay, repair/replace components as necessary.

  5. DTC 43: Check Left Front Wheel Sensor Circuits

    Remove cover from HCU. See COMPONENT LOCATIONS  . Disconnect jumper harness from ABS control module. Check continuity between ground and ABS control module 15-pin harness connector terminals No. 4 (Tan/Orange wire) and No. 12 (Tan/Black wire). See Fig 1 . If continuity does not exist, go to next step. If continuity exists, repair/replace jumper harness, repair circuits No. 521 (Tan/Orange wire) or No. 522 (Tan/Black wire) between ABS control module and left front wheel sensor or replace left front wheel sensor.

  6. Check Left Front Wheel Sensor Air Gap

    Remove left front wheel. Inspect for damaged wheel sensor or toothed indicator ring. Check for objects sticking to wheel sensor or toothed indicator ring. Check for excessive wheel bearing end play. Check air gap between wheel sensor and toothed indicator ring. Air gap should be .019-.037" (.50-.95 mm). If all conditions are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If all conditions are not okay, repair/replace components as necessary.

  7. DTC 44: Check Left Rear Wheel Sensor Circuits

    Remove cover from HCU. See COMPONENT LOCATIONS  . Disconnect jumper harness from ABS control module. Check continuity between ground and ABS control module 15-pin harness connector terminals No. 5 (Orange wire) and No. 13 (Gray/Black wire). See Fig 1 . If continuity does not exist, go to next step. If continuity exists, repair/replace jumper harness, repair circuits No. 496 (Orange wire) or No. 499 (Gray/Black wire) between ABS control module and left rear wheel sensor or replace left rear wheel sensor.

  8. Check Left Rear Wheel Sensor Air Gap

    Remove left rear wheel. Inspect for damaged wheel sensor or toothed indicator ring. Check for objects sticking to wheel sensor or toothed indicator ring. Check for excessive axle bearing end play. Check air gap between wheel sensor and toothed indicator ring. Air gap should be .023-.063" (.60-1.60 mm). If all conditions are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If all conditions are not okay, repair/replace components as necessary.
