AWD SYSTEM
Revision: 2006 January2006 M35/M45
AWD WARNING LAMP
Turns ON when there is a malfunction in AWD system. It indicates that fail-safe mode is engaged and vehicle
change to rear-wheel drive or shifting driving force-AWD (Front-wheels still have some driving torque).
Also turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1
seconds after the engine starts if system is normal.
AWD Warning Lamp Indication
System DiagramNDS000DD
Condition AWD warning lamp
Lamp checkTurns ON when ignition switch is turned ON. Turns OFF
approx. 1 second after engine start.
AWD system malfunctionON
Protection function is activated due to heavy load to electric con-
trolled coupling. (AWD system is not malfunctioning and AWD system
changes to 2WD mode.)Rapid flashing: 2 times/second
(Flashing in approx. 1 minute and then turning OFF)
Large difference in diameter of front/rear tiresSlow flashing: 1 time/2 seconds
(Continuing to flash until turning ignition switch OFF)

3. CHECK AWD SOLENOID
Check AWD solenoid. Refer to TF-30, "
COMPONENT INSPECTION" .
OK or NG
OK >> GO TO 4.
NG >> Replace electric controlled coupling for malfunction of AWD solenoid. Refer to TF-45, "
Disassem-
bly and Assembly" .
4. CHECK AWD CONTROL UNIT
Check AWD control unit input/output signal. Refer to TF-20, "
AWD Control Unit Input/Output Signal Reference
Va l u e s" .
OK or NG
OK >> GO TO 5.
NG >> Check AWD control unit pin terminals for damage or loose connection with harness connector. If
any items are damaged, repair or replace damaged parts.
5. SYMPTOM CHECK
Check again.
OK or NG
OK >>INSPECTION END
NG >> Replace electric controlled coupling for mechanical malfunction (mechanical engagement of
clutch is not possible.). Refer to TF-45, "
Disassembly and Assembly" .
While Driving, AWD Warning Lamp Flashes Rapidly (When Flashing in Approx.
1 Minute and Then Turning OFF)
NDS000DY
NOTE:
Rapid flashing: 2 times/second
This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and
multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid
before lamp flashes rapidly. Both cases are not malfunction.
When this symptom occurs, stop vehicle and allow it to idle for some times. Flashing will stop and system will
be restored.
While Driving, AWD Warning Lamp Flashes Slowly (When Continuing to Flash
until Turning Ignition Switch OFF)
NDS000DZ
NOTE:
Slow flashing: 1 time/2 seconds
DIAGNOSTIC PROCEDURE
1. CHECK TIRE
Check the following.
Tire pressure
Wear condition
Longitudinal tire size (There is no difference between longitudinal tires.)
OK or NG
OK >> GO TO 2.
NG >> Drive at vehicle speed of 20 km/h (12 MPH) or more for 5 seconds or more after repairing or
replacing damaged parts. (Initialize improper size tire information.)

InspectionNES000JO
ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.
a. Remove tire from aluminum wheel and mount on a tire balance machine.
b. Set dial indicator as shown in the figure.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.
a. Remove tire from steel wheel and mount on a tire balance machine.
b. Set two dial indicators as shown in the figure.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel. Wheel runout (Dial indicator value):
Refer to WT-41, "
SERVICE DATA
AND SPECIFICATIONS (SDS)" .
SFA975B
Radial runout = (A+B)/2
Lateral runout = (C+D)/2

ROAD WHEEL TIRE ASSEMBLY
Revision: 2006 January2006 M35/M45
If either residual imbalance value exceeds 7 g (0.25 oz), repeat installation procedures.
RotationNES000JQ
Follow the maintenance schedule for tire rotation service intervals. Refer to MA-7, "PERIODIC MAINTE-
NANCE" .
Do not include the T-type spare tire when rotating the tires.
CAUTION:
When installing wheels, tighten them diagonally by divid-
ing the work two to three times in order to prevent the
wheels from developing any distortion.
Be careful not to tighten wheel nut at torque exceeding
the criteria for preventing strain of disc rotor.
Maximum allowable unbalanceDynamic (At rim flange) Less than 7 g (0.25 oz) (one side)
Static (At flange) Less than 14 g (0.49 oz)
Tightening torque
of wheel nut: 108 Nꞏm (11 kg-m, 80 ft-lb)

TROUBLE DIAGNOSES
Revision: 2006 January2006 M35/M45
ID REGISTRATION WITHOUT ACTIVATION TOOL
This procedure must be done after replacement of a tire pressure transmitter, low tire pressure warn-
ing control unit, or tire rotation.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
during self-diagnosis depending on control unit which performs CAN communication.
1. Turn ignition switch OFF.
2. Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
3. Turn ignition switch ON.
4. Touch “START (NISSAN BASED VHCL)” “AIR PRESSURE MONITOR”.
If “AIR PRESSURE MONITOR” is not displayed, print the “SELECT SYSTEM” screen. Then refer to
LAN-7, "
Precautions When Using CONSULT-II" .
NOTE:
Just after starting engine, or turning ignition switch ON, it may not be displayed even if “START (NIS-
SAN BASED VHCL)” is touched. In this case, reconnect CONSULT-II and CONSULT-II CONVERTER.
5. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen.
6. Touch “ID REGIST” on “SELECT WORK ITEM”.
7. Adjust the tire pressure to the values shown in the table below for ID registration, and drive the vehicle at
40 km/h (25 MPH) or more for a few minutes.
8. After completing all ID registrations, press “END” to complete the procedure.
9. Inflate all tires to proper pressure. Refer to WT-41, "
SERVICE DATA AND SPECIFICATIONS (SDS)" .

TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMSPFP:00000
Inspection 1: Transmitter no DataNES000KA
MALFUNCTION CODE NO. 21, 22, 23, 24
1. CHECK CONTROL UNIT
Drive for several minutes. Check all tire pressures with CONSULT-II “DATA MONITOR”.
Are all tire pressures displayed 0 kPa?
YES >> GO TO 2.
NO >> GO TO 3.
2. CHECK TIRE PRESSURE RECEIVER CONNECTOR
1. Disconnect tire pressure receiver harness connector E74 (FR-LH), E75 (FR-RH), B116 (RR-RH), B115
(RR-LH).
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> Replace low tire pressure warning control unit. Refer to WT-40, "Low Tire Pressure Warning Con-
trol Unit" , then GO TO 3.
NG >> Repair or replace tire pressure receiver harness connector.
3. ID REGISTRATION
Perform ID registration of all transmitters.
Are there any tires that ID can not be registered to?
YES >> Replace transmitter of the tire, then GO TO 5.
NO >> GO TO 4.
4. VEHICLE DRIVING
Drive at a speed of 40 km/h (25 MPH) or more for several minutes without stopping.
Check all tire pressures with CONSULT-II “DATA MONITOR” within 15 minutes after vehicle speed becomes
17 km/h (11 MPH).
Does
“DATA MONITOR ” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO 5.
5. ID REGISTRATION AND VEHICLE DRIVING
1. Perform ID registration of all transmitters.
2. Drive at a speed of 40 km/h (25 MPH) or more for 3 minutes, and then drive the vehicle at any speed for
10 minutes. Then check all tire pressures with CONSULT-II “DATA MONITOR” within 5 minutes.
Does
“DATA MONITOR” display tire pressure as normal without any warning lamp?
YES >> INSPECTION END
NO >> GO TO the inspection applicable to DTC.
