YES >> GO TO 3.
NO >> GO TO 2.
2.PERFORM THE SELF-DIAGNOSIS
1. Perform self-diagnosis with CONSULT.
2. Check if the DTC is detected in self-diagnosis re sults of “AVM”, “MULTI AV” and “METER/M&A”. Refer to
the following.
-AVM: DAS-239, "DTC Index"
- MULTI AV (with BOSE): AV-328, "DTC Index"

- METER/M&A: MWI-27, "DTC Index"
Is any DTC detected?
YES >> Repair or replace malfunctioning parts.
NO >> Inspection End.
3.CHECK DATA MONITOR OF ITS CONTROL UNIT
Check that “MOD SELECT” operates normally in “DATA MONITOR” of “AVM” with CONSULT.
Is the inspection result normal?
YES >> Refer to DAS-233, "CONSULT Function (AVM)".
NO >> GO TO 4.
4.CHECK MULTIFUNCTION SWITCH
Operate the multifunction switch to check that the audio, navigation system, and air conditioner operate prop-
erly.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951577
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Precaution for WorkINFOID:0000000009463020
• When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a shop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusabl e part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
-Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.

Operation Description
• When rear window defogger switch is turned ON while ignition switch is ON, the rear window defogger switch transmits rear window defogger switch signal to BCM.
• BCM turns rear window defogger relay ON when rear window defogger switch signal is received.
• Rear window defogger and door mirror defogger (with door mirror defogger) are supplied with power and
operate when rear window defogger relay turns ON.
• Rear window defogger ON is displayed when front air c ontrol (manual A/C) or A/C switch assembly (auto A/
C) receives signals.
Timer function
• BCM turns rear window defogger relay ON for approx imately 15 minutes when rear window defogger switch
is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door
mirror defogger) operate.
• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch
is turned OFF.
