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.

The Braking Distance is LongNFS000O0
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 E56 to deactivate ABS. In this condition,
check stopping distance. After inspection, connect connector.
OK or NG
OK >>
Bleed air from brake piping.

Check brake system.
NG >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "
Excessive ABS Function Operation Fre-
quency" .
The ABS Function Does Not OperateNFS000O1
CAUTION:
The ABS does not operate when the speed is 10 km/h (6 MPH) or less.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure warning lamp turns off approximately 2 seconds after the ignition switch is turned ON or when driv-
ing.
OK or NG
OK >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "Excessive ABS Function Operation Fre-
quency" .
NG >> Perform self-diagnosis. Refer to BRC-25, "
Self-Diagnosis" .
Pedal Vibration or ABS Operation Sound OccursNFS000O2
CAUTION:
Under the following conditions, when brake pedal is lightly depressed (just place a foot on it), ABS is
activated and vibration is felt. However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1. SYMPTOM CHECK 1
Check if pedal vibration or operation sound occurs when engine is started.
OK or NG
OK >> Perform self-diagnosis. Refer to BRC-25, "Self-Diagnosis" .
NG >> GO TO 2.
2. SYMPTOM CHECK 2
Check symptom when electrical component (headlamps, etc.) switches are operated.
Does the symptom occur when the electrical component (head lamp, etc.) switches are operated?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to ABS actuator and electric unit (control unit) (or its wiring), and if there is, move it farther away.
NO >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "
Excessive ABS Function Operation Fre-
quency" .

ENGINE COOLANT
Revision: 2006 July 2007 FX35/FX45
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to CO-13, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-129,
"ASSEMBLY" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug on heater hose.
4. Fill radiator, and reservoir tank if removed, to specified level.

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.

Use Genuine Nissan Long Life Antifreeze/Coolant or
equivalent mixed with water (distilled or demineralized).
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

When engine coolant overflows air relief hole on heater hose,
install air relief plug with new O-ring.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop the engine and cool down to less than approximately 50 °C (122 °F).

Cool down using fan to reduce the time. Radiator drain plug:

RADIATOR
Revision: 2006 July 2007 FX35/FX45

Pull negative-pressure valve to open it, and make sure that it
close completely when released.
–Make sure that there is no dirt or damage on the valve seat of
radiator cap negative-pressure valve.
–Make sure that there are no unusualness in the opening and
closing conditions of negative-pressure valve.

Check radiator cap relief pressure.
–When connecting radiator cap to the radiator cap tester (com-
mercial service tool) and the radiator cap tester adapter (SST),
apply engine coolant to the cap seal surface.

Replace radiator cap if there is an unusualness related to the above three.
CAUTION:
When installing radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorNBS003JZ
Check radiator for mud or clogging. If necessary, clean radiator as follows.

Be careful not to bend or damage radiator fins.

When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan
assembly and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surfaces once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.

Use compressed air lower than 490 kPa (5 kg/cm2 , 71 psi) and keep distance more than 30 cm (11.81
in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
