TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Wheel Sensor SystemNFS0004D
After using the CONSULT-III 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 the sensor terminal with tester etc.,
because the sensor is an active sensor.

Do not expand the terminal of the connector with a/the tester terminal stick, when it does the
inspection with the tester.
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSIS RESULTS
Check self-diagnosis results.
Is the above displayed in the self-diagnosis display items?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK TIRE
Check air pressure, wear, and size.
Are air pressure, wear, and size within the standard values?
YES >> GO TO 3.
NO >> Adjust air pressure, or replace tire.
3. CHECK SENSOR AND SENSOR ROTOR

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

Check the surface of the front sensor rotor rubber for damage.

Check the rear sensor rotor for damage.
OK or NG
OK >> GO TO 4.
NG >> Repair wheel sensor mount or replace the sensor rotor.
4. CHECK CONNECTOR
1. Disconnect VDC/TCS/ABS control unit connector and malfunctioning wheel sensor connector E42 (FR -
LH) or E27 (FR - RH) or T5 (RR - RH, LH). Check the terminal to see if it is deformed, disconnected,
loose, etc., and replace it if any non-standard condition is found.
2. Reconnect connectors, drive at a speed of approximately 30 km/h (19 MPH) or more for approximately
1minute, and then perform self-diagnosis.
Is the result of self-diagnosis normal?
YES >> The connector terminal contact is loose, damaged, open or shorted.
NO >> GO TO 5.

III the yaw rate sensor system might be displayed, but in this case there is no problem with the yaw
rate sensor system. As soon as the vehicle leaves the turntable or moving object, restart the engine to
return the system to normal.
