RETAINED PWRThis test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-III screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-III might be stuck if “RE-
TAINED PWR” is turned “ON” or “OFF” on CONSULT-III screen when ignition switch is OFF.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001704244
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
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 SR section.
• 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.
PrecautionINFOID:0000000001704245
• Disconnect both battery terminals in advance.
• Disconnect air bag system line in advance.
• Never tamper with or force air bag lid open, as this may adversely affect air bag performance.
• Be careful not to scratch pad and other parts.
• When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
• When removing parts, protect parts by wrapping tools with vinyl or tape.
• Keep removed parts protected with cloth.
• If a clip is deformed or damaged, replace it.
• If an non-reusable part is removed, replace it with a new one.
• Tighten bolts and nuts firmly to the specified torque.
• After re-assembly has been completed, make sure each part functions correctly.
• Remove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Then wipe the area with a soft dry cloth.
• Do not use any organic solvent, such as thinner or benzine.

If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or location of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1. Close a door.
2. Tap or push/pull around the area where the noise appears to be coming from.
3. Rev the engine.
4. Use a floor jack to recreate vehicle “twist”.
5. At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on A/T model).
6. Raise the vehicle on a hoist and hit a tire with a rubber hammer.
• Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
• If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool
(Chassis Ear: J-39570, Engine Ear: J-39565, and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
• Removing the components in the area that you suspect the noise is coming from.
Do not use too much force when removing clips and fasteners, otherwise clips and fasteners
can be broken or lost during the repair, resulting in the creation of new noise.
• Tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be elimi-
nated only temporarily.
• Feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing
the noise.
• Placing a piece of paper between components that you suspect are causing the noise.
• Looking for loose components and contact marks.
Refer to IP-6, "
Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
• If the cause is a loose component, tighten the component securely.
• If the cause is insufficient clearance between components:
- Separate components by repositioning or loosening and retightening the component, if possible.
- Insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or ure-
thane tape. A NISSAN Squeak and Rattle Kit (J-43980) is available through your authorized NISSAN Parts
Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
Always check with the Parts Department for the latest parts information.
The following materials are contained in the NISSAN Squeak and Rattle Kit (J-43980). Each item can be
ordered separately as needed.

CAN COMMUNICATION SYSTEM
FUNCTION DIAGNOSIS
CAN COMMUNICATION SYSTEM
System DescriptionINFOID:0000000001711200
• CAN communication is a multiplex communication system. This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with two communication lines (CAN-H and
CAN-L).
• Control units on the CAN network transmit signals using the CAN communication control circuit. They
receive only necessary signals from other control units to operate various functions.
• CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity.
System DiagramINFOID:0000000001711201
Each control unit passes an electric current to the termination circuits when transmitting CAN communication
signal. The termination circuits produce an electrical potential difference between CAN-H and CAN-L. CAN
communication system transmits and receives CAN communication signals by the potential difference.
