Pinpoint Test B - Wheel Sensor Fault

  1. DTC 31: Check Right Front Wheel Sensor Circuits

    Disconnect 16-pin connector on jumper from HCU assembly to chassis harness connector. See COMPONENT LOCATIONS  . Measure resistance between HCU assembly 16-pin chassis harness connector terminals No. 2 and 13. See Fig 1 . If resistance is 1015-1245 ohms, go to step 3). If resistance is not 1015-1245 ohms, go to next step.

  2. Check Right Front Wheel Speed Sensor

    Disconnect right front wheel sensor harness connector. Measure resistance between wheel sensor connector terminals. If resistance is 1015-1245 ohms, repair circuit No. 514 (Yellow/Red wire) or No. 516 (Yellow/Black wire) between wheel sensor and HCU 16-pin harness connector. If resistance is not 1015-1245 ohms, replace right front wheel sensor.

  3. Check Wiring At Jumper Harness

    Remove cover from HCU. Disconnect jumper harness from ABS control module. Check for broken or damaged wire in jumper harness. If wires are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If wires are not okay, replace broken or damaged wire in jumper harness.

  4. DTC 32: Check Right Rear Wheel Sensor Circuits

    Disconnect 16-pin connector on jumper from HCU assembly to chassis harness connector. See COMPONENT LOCATIONS  . Measure resistance between HCU assembly 16-pin chassis harness connector terminals No. 5 and 9. See Fig 1 . If resistance is 2187-2673 ohms, go to step 6). If resistance is not 2187-2673 ohms, go to next step.

  5. Check Right Rear Wheel Sensor

    Disconnect right rear wheel sensor harness connector. Measure resistance between wheel sensor connector terminals. If resistance is 2187-2673 ohms, repair circuit No. 492 (Brown wire) or No. 494 (Tan/Light Green wire) between wheel sensor and HCU 16-pin harness connector. If resistance is not 2187-2673 ohms, replace right rear wheel sensor.

  6. Check Wiring At Jumper Harness

    Remove cover from HCU. Disconnect jumper harness from ABS control module. Check for broken or damaged wire in jumper harness. If wires are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If wires are not okay, replace broken or damaged wire in jumper harness.

  7. DTC 33: Check left Front Wheel Sensor Circuits

    Disconnect 16-pin connector on jumper from HCU assembly to chassis harness connector. See COMPONENT LOCATIONS  . Measure resistance between HCU assembly 16-pin chassis harness connector terminals No. 3 and 7. See Fig 1 . If resistance is 1015-1245 ohms, go to step 9). If resistance is not 1015-1245 ohms, go to next step.

  8. Check Left Front Wheel Sensor

    Disconnect left front wheel sensor harness connector. Measure resistance between wheel sensor connector terminals. If resistance is 1015-1245 ohms, repair circuit No. 521 (Tan/Orange wire) or No. 522 (Tan/Black wire) between wheel sensor and HCU 16-pin harness connector. If resistance is not 1015-1245 ohms, replace left front wheel sensor.

  9. Check Wiring At Jumper Harness

    Remove cover from HCU. Disconnect jumper harness from ABS control module. Check for broken or damaged wire in jumper harness. If wires are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If wires are not okay, replace broken or damaged wire in jumper harness.

  10. DTC 34: Check Left Rear Wheel Sensor Circuits

    Disconnect 16-pin connector on jumper from HCU assembly to chassis harness connector. See COMPONENT LOCATIONS  . Measure resistance between HCU assembly 16-pin chassis harness connector terminals No. 1 and 6. See Fig 1 . If resistance is 2187-2673 ohms, go to step 12). If resistance is not 2187-2673 ohms, go to next step.

  11. Check Left Rear Wheel Sensor

    Disconnect left rear wheel sensor harness connector. Measure resistance between wheel sensor connector terminals. If resistance is 2187-2673 ohms, repair circuit No. 496 (Orange wire) or No. 499 (Gray/Black wire) between wheel sensor and HCU 16-pin harness connector. If resistance is not 2187-2673 ohms, replace left rear wheel sensor.

  12. Check Wiring At Jumper Harness

    Remove cover from HCU. Disconnect jumper harness from ABS control module. Check for broken or damaged wire in jumper harness. If wires are okay and ANTI-LOCK warning light is constantly on, replace ABS control module. If wires are not okay, replace broken or damaged wire in jumper harness.
