Nissan Sentra Service Manual / Brakes / Brake control system / Dtc/circuit diagnosis / C1105, C1106, C1107, C1108 Wheel sensor

Description

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	Display Item	Malfunction detected condition	Possible causes
C1105	RR RH SENSOR-2	When distance between rear wheel sensor RH and rear wheel sensor RH rotor is large. When installation of rear wheel sensor RH or rear wheel sensor RH rotor is not normal.	Wheel sensor ABS actuator and electric unit (control unit) Sensor rotor
C1106	RR LH SENSOR-2	When distance between rear wheel sensor LH and rear wheel sensor LH rotor is large. When installation of rear wheel sensor LH or rear wheel sensor LH rotor is not normal.
C1107	FR RH SENSOR-2	When distance between front wheel sensor RH and front wheel sensor RH rotor is large. When installation of front wheel sensor RH or front wheel sensor RH rotor is not normal.
C1108	FR LH SENSOR-2	When distance between front wheel sensor LH and front wheel sensor LH rotor is large. When installation of front wheel sensor LH or front wheel sensor LH rotor is not normal.

DTC CONFIRMATION PROCEDURE

1.CHECK SELF DIAGNOSTIC RESULT

With CONSULT.

Start engine and drive vehicle at approximately 21 km/h (13 MPH) or more for approximately 5 minutes.
Perform self diagnostic result.

Is DTC C1105, C1106, C1107 or C1108 detected? YES >> Proceed to diagnosis procedure. Refer to BRC-60, "Diagnosis Procedure".

NO >> Inspection End.

Diagnosis Procedure

Regarding Wiring Diagram information, refer to BRC-44, "Wiring Diagram".

CAUTION:

Do not check between wheel sensor terminals.

1.CONFIRM DTC

With CONSULT

Perform self-diagnostic result of ABS and record all active DTCs.
Clear all DTCs.
Perform DTC confirmation procedure. Refer to BRC-60, "DTC Logic".

Does DTC C1105, C1106, C1107 or C1108 reset? YES >> GO TO 2.

NO >> Refer to GI-39, "Intermittent Incident".

2.CHECK TIRE PRESSURE AND TIRE WEAR

Check tires for excessive wear and proper inflation. Refer to WT-54, "Tire Air Pressure".

Is the inspection result normal? YES >> GO TO 3.

NO >> Repair or replace as necessary.

3.CHECK WHEEL SENSOR

Check wheel sensor for the following:

Proper installation
Physical damage
Contamination

Is the inspection result normal? YES >> GO TO 4.

NO >> Repair or replace as necessary.

4.CHECK SENSOR ROTOR

Check sensor rotor for the following:

Contamination
Physical damage (missing teeth, cracks, etc.)
Foreign material
Looseness

Is the inspection result normal? YES >> Replace the wheel sensor. Refer to BRC-106, "FRONT WHEEL SENSOR : Removal and Installation" or BRC-107, "REAR WHEEL SENSOR : Removal and Installation" . Then, GO TO 5.

NO >> Repair or replace as necessary.

5.CONFIRM REPAIR

With CONSULT

Clear all DTCs.
Perform DTC confirmation procedure. Refer to BRC-60, "DTC Logic".

Does DTC C1105, C1106, C1107 or C1108 reset? YES >> Replace ABS actuator and electric unit (control unit). Refer to BRC-110, "Removal and Installation".

NO >> Inspection End.
