TRANSFER CONTROL DEVICE

Integrates actuator motor and actuator position switch.

Actuator Motor

Moves shift rods when signaled by transfer control unit.

Actuator Position Switch

Detects actuator motor position and then sends signal to transfer control unit.

WAIT DETECTION SWITCH

Detects if transfer case is in 4WD by the 2-4 shift fork position.

Note. If 4WD shift switch is switched to 4H or 4LO and the transfer case is not in 4WD completely, the wait detection system will operate.

4LO SWITCH

4LO switch detects if the transfer case is in 4LO by the position of the L-H shift fork.

ATP SWITCH

ATP switch detects if transfer case is in neutral by the position of the L-H shift fork.

Note. Transfer case may be in neutral when shifting between 4H-4LO.

TRANSFER CONTROL UNIT

1. Transfer control unit controls transfer control device and it directs shifts from 4H-4LO and 2WD-4WD.
2. Self-diagnosis can be done.

TRANSFER SHIFT HIGH AND LOW RELAYS

Transfer shift high and low relays apply power supply to transfer control device (actuator motor).

TRANSFER SHUT OFF RELAYS

Transfer shut off relays 1 and 2 apply power supply to transfer control unit.

Scheme 499

4WD Shift Switch

4WD shift switch is able to select from 2WD, 4H or 4LO.

4WD Shift Indicator Lamp

1. Displays driving conditions selected by the 4WD shift switch while engine is running. When the 4WD warning lamp is turned on, all 4WD shift indicator lamps will turn off.
2. Turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1 second after the engine starts if system is normal. 4LO Indicator Lamp
3. Displays 4LO while engine is running. 4LO indicator lamp flashes if transfer gear does not shift completely into 4H <=>4LO. In this condition, the transfer case may be in neutral and the A/T parking mechanism may not operate.
4. Turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1 second after the engine starts if system is normal.

4WD WARNING LAMP

Turns on or flashes when there is a malfunction in 4WD system.

Also turns on when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1 second after the engine starts if system is normal.

4WD WARNING LAMP INDICATION

ATP WARNING LAMP

When the A/T selector lever is in "P" position, the vehicle may move if the transfer case is in neutral. ATP warning lamp is turned on to indicate this condition to the driver.

ACTUATOR MOTOR

1. Remove transfer control device. Refer to " «REMOVAL AND INSTALLATION»(ref-519813-S00218219472012122900000) ".
2. Check operation by applying battery voltage to transfer control device (actuator motor) terminals 23 and 24. CAUTION: Be careful not to overheat the harness. Terminal Actuator motor 24 (Battery voltage) - 23 (Ground) Clockwise rotate 23 (Battery voltage) - 24 (Ground) Counterclockwise rotate
3. If the inspection results are abnormal replace the transfer control device (actuator motor).

TRANSFER RELAY

1. Turn ignition switch "OFF". (Stay for at least 5 seconds.)
2. Remove transfer shift high relay and transfer shift low relay 2. Refer to " «COMPONENT PARTS LOCATION»(ref-519813-S17114204902012122900000) ".
3. Apply 12V direct current between transfer shift high and low relay terminals 1 and 2.
4. Check continuity between relay terminals 3 and 4, and 3 and 5. Terminal Condition Continuity 3 - 4 12V direct current supply between terminals 1 and 2 No OFF Yes 3 - 5 12V direct current supply between terminals 1 and 2 Yes OFF No

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.

Information necessary to service the system safely is included in the SRS AIRBAG and SEAT BELTS articles of this Service Information.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

Note. This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYSTEM). Remove and install all control units after disconnecting both battery cables with the ignition knob in the "LOCK" position. Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mechanism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation.

Service Notice

1. After overhaul refill the transfer with new transfer fluid.
2. Check the fluid level or replace the fluid only with the vehicle parked on level ground.
3. During removal or installation, keep inside of transfer clear of dust or dirt.
4. Disassembly should be done in a clean work area.
5. Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
6. Check for the correct installation status prior to removal or disassembly. If matchmarks are required, be certain they do not interfere with the function of the parts when applied.
7. All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
8. Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them with a new ones if necessary.
9. Gaskets, seals and O-rings should replaced any time the transfer is disassembled.
10. In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, use it.
11. Observe the specified torque when assembling.
12. Clean and flush the parts sufficiently and blow-dry them.
13. Be careful not to damage sliding surfaces and mating surfaces.
14. Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere with the operation of the transfer.
