TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Wheel Sensor CircuitNFS000NJ
DTC C1101-C1108, C1115
After using the CONSULT-II SELF-DIAG RESULTS to determine the location of the malfunctioning wheel sen-
sor, check all areas to determine the component to be replaced.
CAUTION:

Do not measure the resistance value and also voltage between sensor terminal with tester etc.,
because sensor is an active sensor.

Do not expand terminal of connector with a tester terminal stick, when it does the inspection with
tester.
INSPECTION PROCEDURE
1. CHECK TIRE
Check air pressure, wear and size.
Are air pressure, wear, and size within the standard values?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tire.
2. CHECK SENSOR AND SENSOR ROTOR

Check condition of the sensor mount (for looseness, etc.).

Check surface of front sensor rotor rubber for damage.

Check rear sensor rotor for damage.
OK or NG
OK >> GO TO 3.
NG >> Repair sensor mount or replace sensor rotor.
3. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 4.
NO >> INSPECTION END
4. CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector and malfunctioning wheel sensor con- nector E46 (FR-LH), E33 (FR-RH) or B69 (RR). Check terminal for deformation, open circuit, poor con-
tact, etc., and repair or replace if any malfunctioning condition is found.
2. Reconnect connectors, drive at a speed of approximately 30 km/h (19 MPH) or more for approximately 1 minute, and perform self-diagnosis.
OK or NG
OK >> Connector terminal contact is loose, damaged, open or shorted.
NG >> GO TO 5.

DTC C1113, C1145, C1146
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause the G sensor circuit
indicate a malfunction. However, this is not a malfunction, if normal operation can be resumed after
restarting engine.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
CAUTION:
When on a turntable, such as at a parking structure entrance, or when on a moving object with engine
running, VDC OFF indicator lamp might turn on and self-diagnosis using CONSULT-II the yaw rate sen-
sor system might be displayed, but in this case there is no malfunction in yaw rate sensor circuit. As
soon as vehicle leaves turntable or moving object, restart engine to return the system to normal.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END

Removal and InstallationNFS000O4
REMOVAL
1. Disconnect wheel sensor connector.
2. Remove wheel sensor mounting bolts, grommets (front sensor) and clip.
3. Remove wheel sensor.
CAUTION:
Be careful of the following when installing sensor.

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front wheel hub and bearing assembly and rear final drive. This is to avoid damage to
sensor wiring and loss of sensor function.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the following when installing sensor. Tighten installation bolts to specified torques.

When installing, make sure there is no foreign material such as iron chips on pick-up and mount-
ing hole of sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three loca-
tions shown in the figure (2 at shock absorbers and 1 at body panel). When installed, harness
must not be twisted. White line on harness must be visible from front.
