Component Inspection

INFOID:0000000003766922

1.

CHECK ACTIVE TEST

1.

On “ACTIVE TEST”, select “ABS MOTOR”.

2.

Touch “On” and “Off” on screen. Make sure motor relay and actuator relay operates as shown in table
below.

NOTE:

A brief moment of On/Off condition occurs every 20 seconds after ignition switch turned ON. This is not malfunction because it is
an operation for checking.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Proceed to diagnosis procedure. Refer to 

BRC-94, "Diagnosis Procedure"

.

Special Repair Requirement

INFOID:0000000003767332

1.

ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION

Always perform the neutral position adjustment for the steering angle sensor, when replacing the ABS actua-
tor and electric unit (control unit). Refer to 

BRC-66, "ADJUSTMENT OF STEERING ANGLE SENSOR NEU-

C1115 WHEEL SENSOR

C1115 WHEEL SENSOR

Description

INFOID:0000000003767333

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 “C1115” detected?

YES

>> Proceed to diagnosis. Refer to 

BRC-96, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000003767334
