C1115 WHEEL SENSOR
Description

CHECK TIRES
Check air pressure, wear and size. Refer to
.
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.
