PRE-INSPECTION FOR DIAGNOSTIC
Basic InspectionINFOID:0000000001697628
The engine start function, door lock function, power distribution system and NATS-NVIS system are closely
related to each other regarding control. Narrow down the functional area in question by performing basic
inspection to identify which function is malfunctioning. The vehicle security function can operate only when the
door lock and power distribution system are operating normally. Therefore, it is easy to identify any factor
unique to the vehicle security system by performing the vehicle security operation check after basic inspection.
1. CHECK DOOR LOCK OPERATION
1. Check the door lock for normal operation with the keyfob or Intelligent Key (if equipped) and door request
switch.
Successful door lock operation with the keyfob or Intelligent Key (if equipped) and request SW indicates
that the remote keyless entry receiver and inside key antenna (with Intelligent Key) required for engine
start are functioning normally.
Identify the malfunctioning point by referring to the DLK section if the door cannot be unlocked.
Can the door be locked with the Intelligent Key and door request switch?
YES >> GO TO 2
NO >> Refer to DLK-191, "
DOOR LOCK AND UNLOCK SWITCH : Symptom Table" (with Intelligent Key
without super lock), DLK-420, "
DOOR LOCK AND UNLOCK SWITCH : Symptom Table" (with
Intelligent Key and super lock), DLK-567, "
DOOR LOCK AND UNLOCK SWITCH : Symptom
Table" (without Intelligent Key without super lock) or DLK-718, "DOOR LOCK AND UNLOCK
SWITCH : Symptom Table" (without Intelligent Key with super lock).
2. CHECK ENGINE STARTING
1. Checks that the engine starts.
Does the engine start?
YES >> GO TO 3
NO >> Refer to SEC-76, "
Symptom Table" (with Intelligent Key) or SEC-117, "Symptom Table" (without
Intelligent Key).
3. CHECK STEERING LOCKING (MODELS WITH INTELLIGENT KEY)
1. Does the steering lock when operating door switch after switching the power supply from ON position (or
ACC position) to LOCK position?
If door switch is malfunctioning, BCM cannot lock the steering. If BCM does not detect DTC, steering lock
unit is normal.
Does steering lock?
YES >> GO TO 4
NO >> Refer to STC-29, "
Symptom Chart".
4. CHECK VEHICLE SECURITY SYSTEM
1. Check the vehicle security system for normal operation.
The vehicle security function can operate only when the door lock and power distribution functions are
operating normally.
Therefore, it is easy to identify any factor unique to the vehicle security by performing the vehicle security
operation check after this basic inspection.

How to Handle BatteryINFOID:0000000001723097
CAUTION:
 If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
 After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
 Never add distilled water through the hole used to check specific gravity.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging a battery.
 The battery surface (particularly its top) should always be kept
clean and dry.
 The terminal connections should be clean and tight.
 At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance” and
“maintenance-free”.
 When the vehicle is not going to be used over a long period of
time, disconnect the battery cable from the negative terminal. (If
the vehicle has an extended storage switch, turn it off.)
 Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush with water for 15 minutes and seek medical attention.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001724594
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 SR and SB section 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 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:0000000001724595
When installing each rubber part, final tightening must be car-
ried out under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
Use flare nut wrench when removing or installing brake tubes.
After installing removed suspension parts, check wheel align-
ment.
Do not jack up at the trailing arm and lateral link.
Always torque brake lines when installing.

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
(Engine Ear or 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 fastener 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 eliminated only tem-
porarily.
 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 RF-26, "
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 urethane
tape are available through your authorized Nissan Parts Department.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
Always check with the Parts Department for the latest parts information.
Each item can be ordered separately as needed.
