TROUBLE DIAGNOSIS FOR SYSTEMPFP:00000
Wheel Sensor SystemNFS00026
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 the 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 ABS control unit connector and the 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 connector, drive at a speed of approximately 30 km/h (19 MPH) or more for approximately 1
minute, 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.
