Wheel Sensor SystemNJBR0166
1 TIRE INSPECTION
Check air pressure, wear, and size.
Are air pressure, wear, and size within specifications?
Ye s G O T O 2 .
No Adjust air pressure, or replace tire.
2 SENSOR ROTOR INSPECTION
Check sensor rotor tooth for damage.
OK or NG
OK GO TO 3.
NG Replace sensor rotor.
3 CHECK THE CONNECTOR
1. Remove both the malfunctioning wheel sensor (identified at control unit) and the ABS actuator and electric unit connec-
tor. Check the deformation of the terminal or if the connection is at the incomplete state. Then connect the connectors.
2. Operate self-diagnosis.
