INFOID:0000000003884800
FUNCTION CONFIRMATION PROCEDURE
Check the plasmacluster operation in the function inspection.
1.CHECK PLASMACLUSTER ION CONTROL FUNCTION
1. Start the engine.
2. Turn fan control dial clockwise.
3. Ion indicator is turned ON.
4. Press OFF switch.
5. Ion indicator is turned OFF.
Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 3.
2.CHECK ION CONTROL MODE
1. Turn ignition switch OFF and restart the engine.
2. Turn fan control dial clockwise.
3. Ion indicator (blue) is turned ON.
4. Ion indicator (blue) changes to ion indicator (green) after approximately 15 minutes.
5. Ion indicator (green) changes to ion indicator (blue) after approximately 15 minutes.
6. Press CLEAN switch.
7. Ion indicator (blue) changes to ion indicator (green) after approximately 30 minutes.
8. Ion indicator (green) changes to ion indicator (blue) after approximately 15 minutes.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace A/C auto amp.
3.CHECK WITH ACTIVE TEST OF CONSULT-III
Using CONSULT-III, perform “HVAC TEST” “ACTIVE TEST” of HVAC to check each output device. Refer to
HAC-159, "
WITH INTELLIGENT AIR CONDITIONER SYSTEM : CONSULT-III Function".
NOTE:
 Perform the inspection of each output device after starting the engine because the compressor is operated.
 When choosing to “MODE 7”, error message is displayed but it is not malfunction.
Does plasmacluster system change according to each code No.?
YES >> END.
NO-1 >> Ionizer operation is malfunctioning. Refer to HAC-199, "
WITH INTELLIGENT AIR CONDITIONER
SYSTEM : Component Function Check".
NO-2 >> Ion indicator does not change. Replace A/C auto amp.
NO-3 >> Ion indicator does not illuminate. Refer to AV-640, "
Symptom Table".

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003884811
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”.
 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 har-
ness connectors.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003884812
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.
