EXCESSIVE ABS FUNCTION OPERATION FREQUENCY
Diagnosis ProcedureINFOID:0000000005148086
1.CHECK START
Check front and rear brake force di stribution using a brake tester.
Is the inspection result normal?
YES >> GO TO 2
NO >> Check brake system.
2.CHECK FRONT AND REAR AXLE
Make sure that there is no excessive play in the front and rear axles. Refer to front: FAX-6, "
On-Vehicle
Inspection and Service", Rear: RAX-6, "On-Vehicle Inspection and Service".
Is the inspection result normal?
YES >> GO TO 3
NO >> Repair or replace malfunctioning components.
3.CHECK WHEEL SENSOR AND SENSOR ROTOR
Check the following.
• Wheel sensor installation for damage.
• Sensor rotor installation for damage.
• Wheel sensor connector connection.
• Wheel sensor harness inspection.
Is the inspection result normal?
YES >> GO TO 4
NO >> • Replace wheel sensor or sensor rotor. Refer to BRC-114, "
Removal and Installation".
• Repair harness.
4.CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp is turned off af ter the ignition switch is turned ON or when driving.
Is the ABS warning lamp illuminated?
YES >> Perform self-diagnosis. Refer to BRC-23, "CONSULT-III Function (ABS)".
NO >> Normal

5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000005148094
CAUTION:
• Always use recommended brake fluid. Refer to MA-13, "
Fluids and Lubricants".
• Never reuse drained brake fluid.
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• To clean or wash all parts of master cylin der and disc brake caliper, use clean brake fluid.
• Never use mineral oils such as gasoline or kerosen e. They will ruin rubber parts of the hydraulic sys-
tem.
• Use flare nut wrench when removing and installing brake
tube.
• If a brake fluid leak is found, the part must be disassembled
without fail. Then it has to be replaced with a new one if a
defect exists.
• Turn the ignition switch OFF and remove the connector of the ABS actuator and electric unit (con trol unit) or the battery ter-
minal before performing the work.
• Always torque brake lines when installing.
• Burnish the brake contact surf aces after refinishing or replac-
ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage.
Refer to BR-30, "
Brake Burnishing Procedure" (front disc brake) or BR-35, "Brake Burnishing Proce-
dure" (rear disc brake).
WARNING:
• Clean brake pads and shoes with a waste cl oth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000005148095
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting vehicle, the brake pedal may vibrate or a motor operating noise may be heard from engine
compartment. This is a normal status of operation check.
• Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads.
• When an error is indicated by ABS or another warning lamp, collect all necessary information from customer (what symptoms are present under what conditions) and check for simple causes before starting diagnosis.
Besides electrical system inspection, check boos ter operation, brake fluid level, and fluid leaks.
• If incorrect tire sizes or types are installed on the vehicle or brake pads are not Genuine NISSAN parts, stop-
ping distance or steering stability may deteriorate.
• If there is a radio, antenna or related wiring near control module, ABS function may have a malfunction or
error.
• If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness pinches, open circuits or improper wiring.
• If the following components are replaced with non-genuine components or modified, the VDC OFF indicator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorbers, struts, springs , bushings, etc.), tires, wheels (exclude specified
size), components related to brake system (pads, roto rs, calipers, etc.), components related to engine (muf-
fler, ECM, etc.), components related to body reinforcement (roll bar, tower bar, etc.).
• Driving with broken or excessively worn suspensi on components, tires or brake system components may
cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC system may not
operate properly.
• When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The noise is a result of the normal operation of the TCS and VDC.
• When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as sharp curves on a freeway), the VDC may not operate no rmally, or the VDC warning lamp and the SLIP indi-
cator lamp may turn on. This is not a problem if normal operation can be resumed after restarting the engine.

Removal and InstallationINFOID:0000000005148099
REMOVAL
1. Remove wheel sensor bolt.
• When removing the front wheel sensor, first remove t he disc rotor to gain access to the front wheel sen-
sor bolt. Refer to BR-31, "
Removal and Installation of Brake Caliper and Rotor".
• When removing the rear wheel sensor, first remove the rear hub and bearing assembly to gain access to
the rear wheel sensor bolt. Refer to RAX-8, "
Removal and Installation".
2. Pull out the sensor, being careful to turn it as little as possible. CAUTION:
• Do not pull on the sensor harness.
3. Disconnect wheel sensor harness electrical connec tor, then remove harness from attaching points.
INSTALLATION
Installation is in the reverse order of removal. Tighten wheel sensor bolt to specification.
CAUTION:
• Inspect wheel sensor O-ring, replace sensor assembly if damaged.
• Before installing wheel sensor, make sure no foreign materials (such as iron fragments) are adhered
to the pick-up part of the sensor, to the inside of the sensor hole or on the rotor mating surface.
• Apply a coat of suitable grease to the wheel sensor O-ring and hole. Refer to MA-13, "

PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000005145934
Two different maintenance schedules are provi
ded, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage or ti me intervals, whichever comes first.
Maintenance for Off-road Driving (4WD only)INFOID:0000000005145935
Whenever you drive off-road through sand, mud, or wa ter; more frequent maintenance may be required for the
following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters
