Service NoticeEDS0017L
1. Before proceeding with disassembly, thoroughly clean the outside of the all-mode 4WD transfer. It is
important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
2. Disassembly should be done in a clean work area.
3. Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the all-mode 4WD transfer.
4. Place disassembled parts in order for easier and proper assembly.
5. All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
6. Gaskets, seals and O-rings should be replaced any time the all-mode 4WD transfer is disassembled.
7. It is very important to perform functional tests whenever they are indicated.
8. The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place removed parts in a parts rack in order to replace them in correct positions and sequences. Care will
also prevent springs and small parts from becoming scattered or lost.
9. Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
10. Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, and to hold bearings and washers in place during assembly. Do not use grease.
11. Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
12. After overhaul, refill the transfer with new ATF.
13. When the all-mode 4WD transfer drain plug is removed, only some of the fluid is drained. Old all-mode
4WD transfer fluid will remain in torque converter and ATF cooling system. Always follow the proper pro-
cedure. Refer to MA-24, "
Changing Transfer Fluid" .
Wiring Diagrams and Trouble DiagnosisEDS001CE
When you read wiring diagrams, refer to the following:
 GI-15, "How to Read Wiring Diagrams" .
 PG-4, "POWER SUPPLY ROUTING CIRCUIT" for power distribution circuit.
When you perform trouble diagnosis, refer to the following:
GI-11, "HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES".
GI-27, "How to Perform Efficient Diagnosis for an Electrical Incident".

Description of Electrical PartsEDS0017R
TRANSFER MOTOR
1. The transfer motor drives the sub-oil pump to provide proper lubrication and oil pressure control when the
vehicle is at standstill, during low-speed operations or is being driven in reverse.
2. The main oil pump is operated by the driving force of the mainshaft. In other words, sufficient oil pressure
buildup does not occur when the vehicle is at standstill or during low-speed operations. While the vehicle
is being driven in reverse, the main oil pump rotates in the reverse direction. Therefore the main oil pump
does not discharge oil pressure. During any of the above vehicle operations, the transfer motor drives the
sub-oil pump to compensate for insufficient oil pressure.
3. The transfer motor operates as follows:
1. The motor relay turns OFF in the 2WD mode.
2. The motor relay operates as described in the table below in modes other than the 2WD mode.
Ta b l e 1
Ta b l e 2
NOTE:
OFF (after 2.5 seconds have elapsed.)
4. 4WD shift switch, PNP switch, Neutral-4LO switch, vehicle speed sensor and throttle position sensor are
used in conjunction with the transfer motor.
WAIT DETECTION SWITCH
1. The wait detection switch releases the “booming” torque produced in the propeller shaft. After the release
of the “booming” torque, the wait detection switch helps provide the 4WD lock gear (clutch drum) shifts. A
difference may occur between the operation (“4LO” to “4H” shift only) of the 4WD shift switch and actual
drive mode. At this point, the wait detection switch senses an actual drive mode.
2. The wait detection switch operates as follows:
4WD lock gear (clutch drum) locked: ON
4WD lock gear (clutch drum) released: OFF
3. The wait detection switch senses an actual drive mode and the 4WD shift indicator lamp indicates the
vehicle drive mode.
2-4WD SHIFT SOLENOID VALVE
The 2-4WD shift solenoid valve operates to apply oil pressure to the wet, multiplate clutch, depending on the
drive mode. The driving force is transmitted to the front wheels through the clutch when the vehicle is set in the
4WD mode. Setting the vehicle in the 2WD mode requires no pressure buildup. In other words, pressure force
applied to the wet, multiplate clutch becomes zero.

ID Registration ProcedureEES0012B
ID REGISTRATION WITH TRANSMITTER ACTIVATION TOOL
NOTE:
This procedure must be done after replacement of a low tire pressure warning transmitter or BCM.
New replacement transmitters are provided "asleep" and must first be "woken up" using Transmitter
Activation Tool J-45295 before ID registration can be performed.
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 carries out CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to the data link con-
nector, then turn the ignition switch ON.
2. Select "START (NISSAN BASED VHCL)".
3. Touch “BCM” on "SELECT SYSTEM" screen.
NOTE:
If "BCM" is not indicated, go to LAN-5, "
CAN COMMUNICATION" .
4. Select “AIR PRESSURE MONITOR” on "SELECT TEST ITEM" screen.
5. Select “WORK SUPPORT” on "SELECT DIAG MODE" screen, and select "ID REGIST".
6. With the transmitter activation tool (J-45295) pushed against the
front left transmitter position of the tire air valve, press the button
for 5 seconds.
7. Register the IDs in order from FR LH, FR RH, RR RH and RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and the warning lamp flashes.
8. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.Tool number — (J-45295)

Self-DiagnosisEES0012D
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) for this
system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamp in the combination meter comes on. To start the self-diagnostic results mode, ground the tire
pressure warning check terminal. The malfunction location is indicated by the low tire pressure warning lamp
flashing and the buzzer sounding.
