C1115 WHEEL SENSOR
Description
INFOID:0000000005275280
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.
CHECK SELF-DIAGNOSIS RESULTS
Check the self-diagnosis results.
Is above displayed on the self-diagnosis display?
YES
>> Proceed to diagnosis procedure. Refer to
BRC-231, "Diagnosis Procedure"
NO
>> Inspection End
Diagnosis Procedure
INFOID:0000000005549787
Regarding Wiring Diagram information, refer to
BRC-275, "Wiring Diagram - BRAKE CONTROL SYSTEM -
WITH HILL DESCENT CONTROL/HILL START ASSIST"
.
CAUTION:
Do not check between wheel sensor terminals.
1.
CONNECTOR INSPECTION
1.
Disconnect the ABS actuator and electric unit (control unit) connector and wheel sensor of malfunctioning
code.
2.
Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES
>> GO TO 2
NO
>> Repair or replace as necessary.
2.
CHECK WHEEL SENSOR OUTPUT SIGNAL
1.
Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2.
Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3.
Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES
>> GO TO 3
