A/C AUTO AMP.
DescriptionINFOID:0000000003940951
COMPONENT DESCRIPTION
A/C Auto Amp. (Air Conditioner Automatic Amplifier)
The A/C auto amp. (1) has a built-in microcomputer that processes
information sent from various sensors needed for air conditioner
operation. The air mix door motors, the mode door motor, the intake
door motor, the blower motor and the compressor are then con-
trolled.
When the various switches and temperature control dial are oper-
ated, data is input to the A/C auto amp. from the A/C control.
Component Function CheckINFOID:0000000003940952
1.CHECK OPERATION
1. Press the AUTO switch, and then check that “AUTO” is shown on the display.
2. Operate the temperature control dial (driver side). Check that the fan speed or outlet changes. (The dis-
charge air temperature or fan speed varies depending on the ambient temperature, in-vehicle tempera-
ture, and temperature setting.)
Does it operate normally?
YES >> INSPECTION END
NO >> Perform trouble diagnosis for the A/C system. Refer to HAC-67, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003940953
1.INSPECTION BY FAIL-SAFE FUNCTION
1. Turn the ignition switch ON.
2. After approximately 30 seconds, check that the air conditioner is operated by the fail-safe function (the
operation display of air conditioner is not performed). Refer to HAC-84, "
Fail-Safe".
Is the fail-safe function operated?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK A/C AUTO AMP. POWER SUPPLY CIRCUIT AND GROUND
Check A/C auto amp. power supply circuit and ground circuit. Refer to HAC-65, "
A/C AUTO AMP. : Diagnosis
Procedure".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace parts according to the inspection results.
3.CHECK A/C CONTROL SIGNAL CIRCUIT
Check the A/C control signal circuit. Refer to HAC-74, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> INSPECTION END
NO >> Repair or replace parts according to the inspection results.

INFOID:0000000003854497
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:0000000003854498
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.
