Code 4-4, Right Rear Wheel Speed Sensor

  1. Disconnect right rear wheel speed sensor 2-pin connector. Measure resistance between speed sensor harness connector terminals. If resistance is not 700-1100 ohms, replace speed sensor. If resistance is 700-1100 ohms, go to next step.
  2. Check continuity between Green/Yellow wire terminal of sensor harness connector and ground. If continuity exists, replace sensor. If continuity does not exist, disconnect control unit 22-pin connector. Check continuity between Green/Yellow wire terminal of control unit 22-pin connector and ground.
  3. If continuity exists, Green/Yellow wire between control unit and speed sensor is shorted to ground. If continuity does not exist, check continuity between Blue/Yellow wire terminal of control unit 22-pin connector and ground.
  4. If continuity exists, Blue/Yellow wire between control unit and speed sensor is shorted to ground. If continuity does not exist, reconnect speed sensor 2-pin connector. Measure resistance between Green/Yellow wire and Blue/Yellow wire terminals of control unit 22-pin connector.
  5. If resistance is 700-1100 ohms, go to step 7). If resistance is not 700-1100 ohms, connect jumper wire between Green/Yellow wire terminal of control unit 22-pin connector and ground. Disconnect right rear speed sensor 2-pin connector.
  6. Check continuity between speed sensor Green/Yellow wire terminal and ground. If continuity exists, repair open Blue/Yellow wire between control unit and speed sensor. If continuity does not exist, repair open Green/Yellow wire between control unit and speed sensor.
  7. Check right rear speed sensor air gap and correct if necessary. See WHEEL SENSOR AIR GAP SPECIFICATIONS table under REMOVAL & INSTALLATION. If gap is okay, go to next step if ABS tester is available, or step 10) if ABS tester is not available.
  8. Connect ABS tester to inspection 6-pin connector. See Figure . Start engine. Turn mode selector on ABS tester to mode 3. Firmly depress and hold brake pedal down. Push START TEST switch.
  9. Have assistant manually rotate right front wheel. If wheel cannot be rotated, replace modulator. If wheels can be rotated, problem is intermittent. Test drive vehicle. If symptom reappears, replace control unit.
  10. Disconnect modulator 14-pin connector. Connect battery positive terminal to Red/White wire and Yellow/White wire terminals of modulator 14-pin connector. Connect battery negative terminal and an on-off switch to White wire and Gray/White wire terminals of 14-pin connector.
  11. Firmly depress brake pedal, and momentarily turn on switch to apply ABS function to right rear wheel. Have assistant manually rotate right rear wheel. If wheel cannot be rotated, replace modulator. If wheel can be rotated, problem is intermittent. Test drive vehicle. If symptom reappears, replace control unit.
