Is above displayed in self-diagnosis display items?
1. YES: GO TO 2.
2. NO: Inspection END
CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector E24 and the malfunctioning wheel sensor connector E20 (FR - LH) or E27 (FR - RH) or B202 (RR - LH), B203 (RR - RH). Check terminal to see if it is deformed, disconnected, loose, etc., and repair or replace it if any malfunction condition is found.
2. Reconnect connectors and check that interference with other parts has not cut wheel sensor cables, drive at a speed of 30 km/h (19 MPH) or above for at least 1 minute, and conduct self-diagnosis.
OK or NG
1. OK: Connector terminal contact is loose, damaged, open or shorted.
2. NG: GO TO 3.
CHECK WHEEL SENSOR HARNESS
1. Turn ignition switch OFF and disconnect the wheel sensor connector E20 (FR - LH), E27 (FR - RH), B202 (RR - LH), B203 (RR - RH) and ABS actuator and electric unit (control unit) connector E24.
2. Check continuity between terminals. (Also check continuity when steering wheel is turned right and left and when sensor harness inside the wheel well is moved.)

  Power system: Continuity should exist.
  
  Signal system: Continuity should exits.
  
  Ground system: Continuity should not exist.
OK or NG
1. OK: GO TO 4.
2. NG: Repair harness and connector between ABS actuator and electric unit (control unit) and wheel sensor.
CHECK TIRE
Check air pressure, wear, and size.

Are air pressure, wear, and size within the standard values?
1. YES: GO TO 5.
2. NO: Adjust air pressure, or replace tire.
CHECK SENSOR AND SENSOR ROTOR
1. Check condition of sensor mount (for looseness, etc.).
2. Check surface of front sensor rotor rubber for damage.
3. Check rear sensor rotor for damage.
OK or NG
1. OK: GO TO 6.
2. NG: Repair or replace the malfunctioning component.
CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1. Connect the wheel sensor connector E20 (FR - LH), E27 (FR - RH), B202 (RR - LH), B203 (RR - RH) and ABS actuator and electric unit (control unit) connector E24.
2. Turn on ignition switch and check the voltage between the power supply terminal and the ground.
  Voltage
  
  Front RH 1 (B) - Ground: 8 V or more
  
  Front LH 1 (G) - Ground: 8 V or more
  
  Rear RH 1 (LG) - Ground: 8 V or more
  
  Rear LH 1 (L) - Ground: 8 V or more

OK or NG
1. OK: Replace wheel sensor.
2. NG: Replace the ABS actuator and electric unit (control unit).
