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-103, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000000977403

CAUTION:

Do not check between wheel sensor terminals.

INSPECTION PROCEDURE

1.

CHECK SENSOR AND SENSOR ROTOR

• Check sensor rotor for damage. 
• Check wheel sensor for damage, disconnection or looseness.
Are the sensor and sensor rotor normal?

YES

>> GO TO 2.

NO

>> Repair wheel sensor mount or replace sensor rotor. Then perform the self-diagnosis.

2.

CHECK CONNECTOR

1.

Turn ignition switch OFF.

2.

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

3.

Disconnect malfunctioning wheel sensor connector.

4.

Check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or
replace terminal.

5.

Reconnect connectors and then perform the self-diagnosis. Refer to 

BRC-96, "CONSULT-III Function

(ABS)"

.

Is any item indicated on the self-diagnosis display?

DTC

Display item

Malfunction detected condition

Possible cause

C1105

RR RH SENSOR-2

Signal from rear RH wheel sensor does not match other 
3 wheel speed signal.

• Sensor not installed corretly
• Sensor rotor or encoder dam-

aged

• Sensor rotor loose on axle
• Electrical interference
• Wheel not turning - e.g. vehi-

cle driven on 2WD dyno

• Sensor damaged
• ABS unit damaged

C1106

RR LH SENSOR-2

Signal from rear LH wheel sensor does not match other 
3 wheel speed signal.

C1107

FR RH SENSOR-2

Signal from front RH wheel sensor does not match other 
3 wheel speed signal.

C1108

FR LH SENSOR-2

Signal from front LH wheel sensor does not match other 
3 wheel speed signal.

< COMPONENT DIAGNOSIS >

[ESP/TCS/ABS]

C1105, C1106, C1107, C1108 WHEEL SENSOR-2

YES

>> GO TO 3.

NO

>> Poor connection of connector terminal. Repair or replace connector.

3.

CHECK WHEEL SENSOR HARNESS

1.

Turn ignition switch OFF.

2.

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

3.

Disconnect malfunctioning wheel sensor connector.

4.

Check continuity between terminals. (Also check continuity when steering wheel is turned right and left
and when sensor harness inside the wheel house is moved.)

Measurement terminal for power supply circuit

Measurement terminal for signal circuit

Measurement terminal for ground circuit

5.

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

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace malfunctioning components.

4.

CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT

1.

Turn ignition switch ON.

2.

Check voltage between wheel sensor harness connector power supply terminal and ground.

Is the inspection result normal?

YES

>> Replace applicable wheel sensor.

NO

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