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.

TROUBLE DIAGNOSIS FOR SYSTEM
Revision: 2006 November2007 350Z
5. CHECK WHEEL SENSOR HARNESS
1. Turn ignition switch OFF and disconnect the wheel sensor con-
nector E42 (FR - LH) or E27 (FR - RH) or T5 (RR - RH, LH) and
ABS control unit (control unit) connector E51.
2. Check continuity between terminals. (Also check the continuity
when the steering wheel is turned right and left and when the
sensor harness inside the wheel well is moved.)
OK or NG
OK >> GO TO 6.
NG >> Repair or replace harness and connector that have malfunction.
6. CHECK WHEEL SENSOR POWER SUPPLY CIRCUIT
1. Disconnect malfunctioning wheel sensor connector.
2. Turn ignition switch ON and check voltage between wheel sen-
sor harness connector power supply terminal and ground.
OK or NG
OK >> Replace wheel sensor.
NG >> Replace ABS actuator and electric unit (control unit).

TROUBLE DIAGNOSIS FOR SYMPTOMSPFP:00007
Excessive ABS Function Operation FrequencyNFS0002E
1. CHECK START
Check brake force distribution.
OK or NG
OK >> GO TO 2.
NG >> Check brake system.
2. CHECK FRONT AND REAR AXLE
Make sure there is no excessive play in the front and rear axles.
OK or NG
OK >> GO TO 3.
NG >> Repair.
3. CHECK WHEEL SENSOR AND SENSOR ROTOR
Wheel Sensor Inspection

Wheel sensor mount and damage inspection

Sensor rotor mount and damage inspection

Wheel sensor connector connection inspection

Wheel sensor harness inspection
OK or NG
OK >> GO TO 4.
NG >>

Replace wheel sensor or sensor rotor.

Repair harness.
4. CHECK ABS WARNING LAMP DISPLAY
Make sure warning lamp turns off approximately 1 second after the ignition switch is turned on or when driv-
ing.
OK or NG
OK >> Normal
NG >> Perform self-diagnosis. Refer to BRC-19, "
OPERATION PROCEDURE" .
Unexpected Pedal ReactionNFS0002F
1. CHECK BRAKE PEDAL STROKE
Check brake pedal stroke.
Is the stroke too big?
YES >>
Bleed air from the brake piping.

Check brake pedal, brake booster, and master cylinder mount for play, looseness, and brake
system for fluid leaks, etc. If any malfunctions are found, make repairs.
NO >> GO TO 2.
2. CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector, and make sure the braking force is suffi-
cient when the ABS is not operating. After the inspection, reconnect the connector.
OK or NG
OK >> GO TO 3. CHECK WHEEL SENSOR AND SENSOR ROTOR in BRC-32, "Excessive ABS Func-
tion Operation Frequency" .
NG >> Check brake system.

The Braking Distance is LongNFS0002G
CAUTION:
On slippery road surfaces, the stopping distance might be longer with the ABS operating than when
the ABS is not operating.
1. CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector to deactivate ABS. In this condition, check
stopping distance. After inspection, connect connector.

Removal and InstallationNFS0002J
COMPONENTS
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

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 or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts and nuts to specified torques.

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor motor. 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 locations
shown in diagram (2 at shock absorbers and 1 at body panel). When installed, harness must not be
twisted. White line on harness (shaded part) must be visible from front.
