PRECAUTIONS PRECAUTIONS PFP:00001 Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
UDS0008W
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 and SB section of this Service Manual. WARNING: ● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. ● Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section. ● Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.
Precautions for Transfer Assembly and Transfer Control Unit Replacement ●
UDS000DE
When replacing transfer assembly or transfer control unit, check the 4WD shift indicator pattern and adjustment of the position between transfer assembly and transfer control unit if necessary.
CHECK 4WD SHIFT INDICATOR PATTERN 1. 2.
Set 4WD shift switch to “2WD”, “4H”, “4LO”, “4H” and “2WD” in order. (Stay at each switch position for at least 2 seconds.) Confirm 4WD shift indicator lamp and 4LO indicator lamp are changed properly as follows.
SDIA2481E
● ●
If OK, the position between transfer assembly and transfer control unit is correct. If NG, the position is different between transfer assembly and transfer control unit. Adjust the position between transfer assembly and transfer control unit. Refer to pattern table below.

PRECAUTIONS Precautions ●
UDS0008X
Before connecting or disconnecting the transfer control unit harness connector, turn ignition switch “OFF” and disconnect battery ground cable. Because battery voltage is applied to transfer control unit even if ignition switch is turned “OFF”.
SEF289H
●
When connecting or disconnecting pin connectors into or from transfer control unit, take care not to damage pin terminals (bend or break). When connecting pin connectors make sure that there are not any bends or breaks on transfer control unit pin terminal.
SEF291H
●
Before replacing transfer control unit, perform transfer control unit input/output signal inspection and make sure whether transfer control unit functions properly or not. Refer to TF-27, "Transfer Control Unit Input/Output Signal Reference Values" .

UDS0008Y
After overhaul refill the transfer with new transfer fluid. Check the fluid level or replace the fluid only with the vehicle parked on level ground. During removal or installation, keep inside of transfer clear of dust or dirt. Disassembly should be done in a clean work area. 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. 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. All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly. Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them with a new ones if necessary. Gaskets, seals and O-rings should replaced any time the transfer is disassembled. In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, use it. Observe the specified torque when assembling. Clean and flush the parts sufficiently and blow-dry them. Be careful not to damage sliding surfaces and mating surfaces.

TROUBLE DIAGNOSIS TROUBLE DIAGNOSIS How to Perform Trouble Diagnosis
PFP:00004 UDS0009A
BASIC CONCEPT ●
●
To perform trouble diagnosis, it is the most important to have understanding about vehicle systems (control and mechanism) thoroughly. It is also important to clarify customer complaints before inspection. First of all, reproduce symptoms, and understand them fully. Ask customer about his/her complaints carefully. In some cases, it will be necessary to check symptoms by driving vehicle with customer. CAUTION: Customers are not professional. It is dangerous to make an easy guess like "maybe the customer means that...," or "maybe the customer mentions this symptom". SEF233G

It is essential to check symptoms right from the beginning in order to repair malfunctions completely. For intermittent malfunctions, reproduce symptoms based on interview with customer and past examples. Do not perform inspection on ad hoc basis. Most intermittent malfunctions are caused by poor contacts. In this case, it will be effective to shake suspected harness or connector by hand. When repairing without any symptom diagnosis, you cannot judge if malfunctions have actually been eliminated. After completing diagnosis, always erase diagnostic memory. Refer to TF-37, "ERASE SELF-DIAGNOSIS" . For intermittent malfunctions, move harness or harness connector by hand. Then check for poor contact or reproduced open circuit.

TROUBLE DIAGNOSIS Self-Diagnostic Procedure
UDS000A2
SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II) Refer to TF-33, "SELF-DIAG RESULT MODE" .
SELF-DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-II) Description If the engine starts when there is something wrong with the 4WD system, the 4WD warning lamp turns ON or flickers in the combination meter. When the system functions properly, the warning lamp turns ON when the ignition switch is turned to “ON”, and it turns OFF after engine starts. To locate the cause of a problem, start the self-diagnosis function. The 4WD warning lamp in the combination meter will indicate the problem area by flickering according to the self-diagnostic results. As for the details of the 4WD warning lamp flickering patterns, refer to TF-36, "Diagnostic procedure" .
Diagnostic procedure 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
Warn up engine. Turn ignition switch “ON” and “OFF” at least twice, and then turn ignition switch “OFF”. Move A/T selector lever to “P” position. Turn 4WD shift switch to “2WD” position. Turn ignition switch “ON”. (Do not start engine.) 4WD warning lamp ON. If 4WD warning lamp does not turn ON, refer to TF-70, "4WD Warning Lamp Does Not Turn ON" . Move A/T selector lever to “R” position. Turn 4WD shift switch to “2WD”, “4H” and “2WD” in order. Move A/T selector lever to “P” position. Turn 4WD shift switch to “4H”, “2WD” and “4H” in order. Move A/T selector lever to “N” position. Turn 4WD shift switch to “2WD” position. Move A/T selector lever to “P” position. Read the flickering of 4WD warning lamp. Refer to TF-36, "Judgement self-diagnosis" .
Judgement self-diagnosis When a malfunction is detected, the malfunction route is indicated by flickering of the 4WD warning lamp.

In order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is stored into the control unit as necessary during use by the user. This memory is not erased no matter how many times the ignition switch is turned ON and OFF. However, this information is erased by turning ignition switch “OFF” after performing self-diagnostics or by erasing the memory using the CONSULT-II.
