TROUBLE DIAGNOSIS FOR
SELF-DIAGNOSTIC ITEMS
TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
Wheel Sensor SystemINFOID:0000000005397040
INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace as necessary.
2.CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. Turn on the ABS active wheel sensor tester power switch. NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and
retest.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-34, "
Removal and Installation".
3.CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-28
.
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4.
NO >> Adjust tire pressure or replace tire(s).
4.CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-6, "
On-Vehicle Inspection and Service" or RAX-6, "On-Vehi-
cle Inspection and Service".
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FA X - 6 , "
Removal and Installation" or RAX-6, "Removal
and Installation".
5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ABS actuator and elec tric unit (control unit) connec-
tor and wheel sensor connector of malfunction code No.
3. Check continuity between wheel sensor harness connector ter- minals and ground.
OK or NG
OK >> GO TO 6.
NG >> Repair the circuit.
6.CHECK WIRING HARNESS FOR OPEN CIRCUIT Continuity should not exist.

PRECAUTIONS
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 a ll control units using CONSULT-III.
Precaution for Brake SystemINFOID:0000000005612137
CAUTION:
• Refer to MA-14, "
Fluids and Lubricants" for recommended brake fluid.
• 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 kerosene. 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 an d remove the connector of the
ABS actuator and electric unit (c ontrol 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-34, "
Brake Burnishing Procedure".
WARNING:
• Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precaution for Brake ControlINFOID:0000000005612138
• 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 la mp, 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 booste r operation, brake fluid level, and fluid leaks.
• If incorrect tire sizes or types are installed on the v ehicle 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, spri ngs, bushings, etc.), tires, wheels (exclude specified
size), components related to brake system (pads, rotors , 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 suspension components, tires or brake system components may cause the VDC OFF indicator lamp and the SLIP indi cator lamp to turn on, and the VDC system may not
operate properly.
• When the TCS or VDC is activated by sudden accele ration 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 nor mally, 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.

TROUBLE DIAGNOSIS
• Inspect for fluid leakage and check the fluid level. Refer to
CVT-14, "Checking CVT Fluid" .
Fluid Condition Check
Inspect the fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the
CVT fluid temperature is 50 to 80 °C (122 to 176° F). Inspect the
amount of CVT fluid. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Install a tachometer where it can be seen by driver during test. •It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D” position.

TROUBLE DIAGNOSIS
The CVT fluid temperature rises in the range of 50 - 80
°C (122 - 176° F) during 10 minutes of driving.
3. After warming up CVT, remove the oil pressure detection plug and install the oil pressure gauge [special service tool: - (OTC3492)].
CAUTION:
When using the oil pressure gauge, be sure to u se the O-ring attached to the oil pressure detec-
tion plug.
4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, and then measure the line pressure at both idle and the stall speed.
CAUTION:
• Keep the brake pedal pressed all the way down duringmeasurement.
• When measuring the line pressure at the stall speed, refer
to "STALL TEST" .
6. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque below.
CAUTION:
• Do not reuse O-ring.
• Apply CVT fluid to O-ring.
