PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001731063
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.

DIAGNOSIS AND REPAIR WORKFLOW
1. GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred).
>> GO TO 2
2. CONFIRM THE SYMPTOM
Confirm the symptom described by the customer.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 3
3. PERFORM BASIC INSPECTION
Perform XX-XX, "*****"
.
Inspection End>>GO TO 4
4. 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.
>> GO TO 5
5. DETECT MALFUNCTIONING PART BY DIAGNOSTIC PROCEDURE
Inspect according to Diagnostic Procedure of the system.
NOTE:
The Diagnostic Procedure described based on open circuit inspection. A short circuit inspection is also
required for the circuit check in the Diagnostic Procedure.
Is malfunctioning part detected?
YES >> GO TO 6
NO >> Check voltage of related BCM terminals using CONSULT-III.
6. REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnostic Procedure.
>> GO TO 7
7. FINAL CHECK
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that
the symptom is not detected.
Does the symptom reappear?
YES >> GO TO 5
NO >> Inspection End.

MEMORY RESET PROCEDURE
1. Please observe the following instructions while confirming the sunroof operation.
NOTE:
Do not disconnect the battery power while the sunroof is operating or within 5 seconds after the sunroof
stops (to wipe-out the memory of lid position and operating friction).
2. Initialization of system should be conducted after the following conditions.
When the battery has been disconnected or discharged.
When the sunroof motor has been disconnected from power.
When the sunroof motor is changed.
When the sunroof does not operate normally (Incomplete initialization conditions).

quirement
INFOID:0000000001724557
INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to
normal.
1. Turn ignition switch ON.
2. Push and release the tilt up switch to start the tilt up operation.
3. Push and hold the tilt up switch until the sunroof pops up.
NOTE:
The sunroof will move toward the tilt up direction and will be stopped mechanically, at which time it will be
automatically fully closed. Keep pushing the switch during this operation. Release the switch when the
operation is complete.
4. Push and hold the tilt up switch within 10 seconds of step 3.
5. After 4 seconds, the sunroof will be automatically cycled in sequence of slide open-tilt up-tilt down.
NOTE:
Keep pushing the switch during this operation.
6. When the sunroof stops, release the switch 0.5 second later.
7. If the slide switch operates normally, the initialization is complete.

System DescriptionINFOID:0000000001724559
SUNROOF SYSTEM
INPUT/OUTPUT SIGNAL CHART
SUNROOF OPERATION
The sunroof motor assembly is supplied with constant battery power. The BCM supplies power while the
ignition switch is ON or retained power is operating.
The open & close signals from the sunroof switch enable the sunroof motor to move arbitrarily.
AUTO OPERATION
The sunroof AUTO feature makes it possible to slide open and slide close or tilt up and tilt down the sunroof
without holding the sunroof switch in the slide open/tilt down or slide close/tilt up position.
RETAINED POWER OPERATION
Retained power operation is an additional power supply function that enables the sunroof system to operate
up to 45 seconds after the ignition switch is turned OFF.
Retained power function cancel conditions
When a front door is opened (door switch ON)
When ignition switch is turned ON again.
When 45 seconds elapse on the timer.
ANTI-PINCH FUNCTION
The CPU (central processing unit) of the sunroof motor assembly monitors the sunroof motor operatin and the
sunroof position (fully-closed or other) by signals from the sunroof motor.
When the sunroof motor detects an interruption during the slide close or tilt down operation, the sunroof motor
assembly will reverse to slide open or tilt up.
