tion (BCM - INTELLIGENT KEY)INFOID:0000000009941331
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

< BASIC INSPECTION >[POWER DISTRIBUTION SYSTEM]
DIAGNOSIS AND REPAIR WORKFLOW
1.GET INFORMATION FOR SYMPTOM
1. Get detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurs).
2. Check operation condition of the com ponent or system that is malfunctioning.
>> GO TO 2.
2.CHECK DTC
1. Check DTC.
2. Perform the following procedure if DTC is detected.
- Record DTC and freeze frame data (P rint them out using CONSULT).
- Erase DTC.
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
3. Check related service bulletins for information.
Are any symptoms described and any DTC detected?
Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>GO TO 5.
3.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
Also study the normal operation and fail-safe related to the symptom.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
Verify relation between the symptom and the condition when the symptom is detected.
NOTE:
Freeze frame data is useful if the DTC is not detected.
>> GO TO 6.
5.PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC CONFIRMATION PROCEDURE for the det ected DTC, and then check that DTC is detected
again. At this time, always connect CONSULT to the v ehicle, and check self diagnostic results in real time.
If two or more DTCs are detected, refer to BCS-50, "DTC Inspection Priority Chart"
, and determine trouble
diagnosis order.
Is DTC detected?
YES >> GO TO 7.
NO >> Refer to GI-43, "Intermittent Incident"
.
6.DETECT MALFUNCTIONING SYSTEM BY SYMPTOM DIAGNOSIS
Detect malfunctioning system according to SYMPTOM DIAGNOSIS based on the confirmed symptom in step
4, and determine the trouble diagnosis order based on possible causes and symptom.
Is the symptom described?
YES >> GO TO 7.
NO >> Monitor input data from related sensors or check voltage of related module terminals using CON- SULT.
7.DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE
Inspect according to Diagnos is Procedure of the system.
Is malfunctioning part detected?
YES >> GO TO 8.
NO >> Refer to GI-43, "Intermittent Incident"
.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951599
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 the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified 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 Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 minutes before performing any service.

HOW TO READ HARNESS LAYOUT
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:
• Main Harness, Console Sub-harness, Speaker Sub-harness
• Engine Room Harness
• Engine Room Harness (Passenger Compartment)
• Front End Module Harness, Fr ont Combination Lamp Sub-har-
ness, Front Fog Lamp Sub-harness
• Engine Control Harness (QR25DE)
• Engine Control Harness (VQ35DE), Knock Sensor Sub-harness
