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

C1115 WHEEL SENSOR

Description

INFOID:0000000003767292

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 DETECTION LOGIC

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-27, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000003767293

CAUTION:

Do not check between wheel sensor terminals.

1.

CHECK TIRES

Check air pressure, wear and size. Refer to 

WT-5, "Tire Air Pressure"

.

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.

CHECK CONNECTOR

1.

Turn the ignition switch OFF.

2.

Disconnect ABS actuator and electric unit (control unit) connector.

3.

Disconnect malfunctioning wheel sensor connector.

4.

Check terminal to see if it is deformed, disconnected, looseness, etc.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace damaged parts.

4.

CHECK WHEEL SENSOR HARNESS

1.

Check the continuity between ABS actuator and electric unit (control unit) harness connector and wheel
sensor harness connector. (Also check continuity when steering wheel is turned right and left and when
sensor harness inside the wheel house is moved.)

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair or replace damaged parts.

6.

CHECK DATA MONITOR

1.

Turn the ignition switch OFF.

2.

Connect each wheel sensor connector.

3.

Check wheel sensor signal. Refer to 

BRC-29, "Component Inspection"

.

Is the inspection result normal?

YES

>> Replace ABS actuator and electric unit (control unit).

NO

>> Repair or replace damaged parts.
