Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003844112
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. Information necessary to service the system safely is included in the “SRS AIRBAG” and
“SEAT BELT” 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 AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003844113
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.

4. Remove mounting bolt (A), and then disconnect low-pressure
flexible hose (1) from compressor.
CAUTION:
Cap or wrap the joint of the A/C piping and compressor with
suitable material such as vinyl tape to avoid the entry of air.
5. Remove mounting bolt (B), and then disconnect high-pressure
flexible hose (2) from compressor.
CAUTION:
Cap or wrap the joint of the A/C piping and compressor with
suitable material such as vinyl tape to avoid the entry of air.
6. Remove under cover. Refer to EXT-28, "
Exploded View".
7. Remove splash guard. Refer to EXT-22, "
FENDER PROTECTOR : Exploded View".
8. Remove drive belt. Refer to EM-12, "

INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
 Replace O-rings with new ones. Then apply compressor oil to them when installing.
 Check for leakages when recharging refrigerant.
 Check tension of the drive belt after installing compressor. Refer to EM-12, "
Checking".
InspectionINFOID:0000000003839904
CHECK DISC TO PULLEY CLEARANCE
1. Check the clearance (B) between pulley assembly (1) and clutch

Diagnosis Proce-
dure".
NO-4 >> Discharge air temperature does not change (passenger side). Refer to HAC-59, "
Diagnosis Pro-
cedure".
NO-5 >> Blower motor does not operate normally. Refer to HAC-68, "
Diagnosis Procedure".
NO-6 >> Magnet clutch does not operate. Refer to HAC-72, "
Diagnosis Procedure".
7.CHECK DRIVE BELT
Check tension of the drive belt. Refer to EM-12, "
Checking".
Is the inspection result normal?
YES >> GO TO 8.

YES-2 >> Noise from compressor: GO TO 3.
YES-3 >> Noise from expansion valve: GO TO 4.
YES-4 >> Noise from A/C piping (pipe, flexible hose): GO TO 6.
YES-5 >> Noise from drive belt: GO TO 7.
NO >> END.
2.CHECK BLOWER MOTOR
1. Remove blower motor.
2. Remove foreign materials that are in the blower unit.
3. Check the noise from blower motor again.
Is the inspection result normal?
YES >> END.
NO >> Replace blower motor.
3.CHECK COMPRESSOR
Perform trouble diagnosis for the compressor and check the compressor. Refer to HA-11, "
Symptom Table".
Is the inspection result normal?
YES >> END.
NO >> Refill the refrigerant or replace the compressor according to the inspection results.
4.CHECK WITH GAUGE PRESSURE
Perform the diagnosis with the gauge pressure. Refer to HA-8, "
Trouble Diagnosis For Unusual Pressure".
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace parts according to the inspection results.
5.CHECK EXPANSION VALVE
1. Correct the refrigerant with recovery/recycling recharging equipment.
2. Recharge with the proper amount of the collected refrigerant after recycling or new refrigerant.
3. Check for the noise from expansion valve again.
Are the malfunction solved?
YES >> END.
NO >> Replace expansion valve.
6.CHECK A/C PIPING (PIPE, FLEXIBLE HOSE)
1. Check the A/C piping (pipes, flexible hoses) (for deformation and damage, etc.).
2. Check the installation condition of clips and brackets, etc, of the A/C piping (pipes, flexible hoses).
Is the inspection result normal?
YES >> Fix the line with rubber or come vibration absorbing material.
NO >> Repair or replace parts according to the inspection results.
