■ CAUTION ■
Never check between wheel sensor terminals.
 1.CHECK TIRES
Check air pressure, wear and size. Refer to Tire. Is the inspection result normal? YES >>GO TO 2. NO >>Repair or replace error-detected parts.
 2.CHECK SENSOR AND SENSOR ROTOR
 3.CHECK CONNECTOR
- Turn the ignition switch OFF.
- Disconnect ABS actuator and electric unit (control unit) connector.
- Disconnect malfunctioning wheel sensor connector.
- Check terminal to see if it is deformed, disconnected, loose, etc.
Is the inspection result normal?
YES >>GO TO 4. NO >>Repair or replace error-detected parts.
 4.CHECK WHEEL SENSOR HARNESS
- Check the continuity between the ABS actuator and electric unit (control unit) harness connector and wheel sensor harness connector. (Also check continuity when steering wheel is turned right and left and when sensor harness inside the wheel house is moved)
