DescriptionINFOID:0000000003766902
When the sensor rotor rotates, the magnetic field changes. Wheel sensor converts the magnetic field changes
to current signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Start the engine and drive the vehicle at 30 km/h (19 MPH) or more for approximately 1 minute.
2. Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is DTC
“C1101”, “C1102”, “C1103” or “C1104” detected?
YES >> Proceed to diagnosis. Refer to BRC-85, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766904
CAUTION:
Do not check between wheel sensor terminals.
1.CHECK TIRES
Check air pressure, wear and size. Refer to WT-5, "
Tire Air Pressure".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK SENSOR AND SENSOR ROTOR
Check sensor rotor for damage.
Check wheel sensor for damage, disconnection or looseness.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.
3.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Disconnect malfunctioning wheel sensor connector.
4. Check terminal to see if it is deformed, disconnected, looseness, etc.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace damaged parts.
