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 DETECTION LOGIC

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 

BRC-50, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009718262
