C1115 WHEEL SENSOR
C1115 WHEEL SENSOR
Description
INFOID:0000000009718260
When the sensor rotor rotates, the magnetic field changes. It 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.
PRECONDITIONING
If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn the ignition switch OFF
and wait at least 10 seconds before conducting the next test.
>> GO TO 2.
2.
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 self-diagnosis for “ABS” with CONSULT.
Is DTC “C1115” detected?
YES
>> Proceed to diagnosis procedure. Refer to
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000009718262
CAUTION:
Never check the between wheel sensor harness connector terminals.
1.
CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY SYSTEM
Check the ABS actuator and electric unit (control unit) power supply system. Refer to
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace error-detected parts.
2.
