PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A
BELT PRE-TENSIONER"
NIS0015N
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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.
C
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
D
q 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 per-
formed by an authorized NISSAN/INFINITI dealer.
E
q Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
F
q 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
harness connectors.
G
Precautions for Work
NIS0015O
q After removing and installing the opening/closing parts, be sure to carry out fitting adjustments to check
their operation.
H
q Check the lubrication level, damage, and wear of each part. If necessary, grease or replace it.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions that exist when the noise occurs.Use the Diag- H nostic Worksheet during the interview to document the facts and conditions when the noise occurs and any customer's comments; refer to BL-11, "Diagnostic Worksheet" . This information is necessary to duplicate the conditions that exist when the noise occurs.
BL q The customer may not be able to provide a detailed description or the location of the noise. Attempt to
obtain all the facts and conditions that exist when the noise occurs (or does not occur).
q
If there is more than one noise in the vehicle, be sure to diagnose and repair the noise that the customer is concerned about. This can be accomplished by test driving the vehicle with the customer.
J
q After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
K
q Squeak --(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=lower pitch noises/edge to surface=chirping
L
q Creak--(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow movement/twisting with a rotational movement/pitch
dependent on materials/often brought on by activity.
M
q Rattle--(Like shaking a baby rattle) Rattle characteristics include the fast repeated contact/vibration or similar movement/loose parts/missing clip or fastener/incorrect clearance.
q Knock --(Like a knock on a door) Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
q Tick--(Like a clock second hand) Tick characteristics include gentle contacting of light materials/loose components/can be caused by driver action or road conditions.
q Thump--(Heavy, muffled knock noise) Thump characteristics include softer knock/dead sound often brought on by activity.
q Buzz--(Like a bumble bee) Buzz characteristics include high frequency rattle/firm contact.
q Often the degree of acceptable noise level will vary depending upon the person. A noise that you may judge as acceptable may be very irritating to the customer.
q Weather conditions, especially humidity and temperature, may have a great effect on noise level.

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
DUPLICATE THE NOISE AND TEST DRIVE
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 duplicate 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.
q Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
q 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 and mechanics stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by:
q 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.
q 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 temporarily.
q feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the noise.
q placing a piece of paper between components that you suspect are causing the noise.
q looking for loose components and contact marks. Refer to BL-9, "Generic Squeak and Rattle Troubleshooting" .
REPAIR THE CAUSE
q If the cause is a loose component, tighten the component securely.
q 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. 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.
NOTE: 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. URETHANE PADS [1.5 mm (0.059 in) thick] Insulates connectors, harness, etc. 76268-9E005: 100 × 135 mm (3.94 × 5.31 in)/76884-71L01: 60 × 85 mm (2.36 × 3.35 in)/76884-71L02: 15 × 25 mm (0.59 × 0.98 in) INSULATOR (Foam blocks) Insulates components from contact.Can be used to fill space behind a panel. 73982-9E000: 45 mm (1.77 in) thick, 50 × 50 mm (1.97 × 1.97 in)/73982-50Y00: 10 mm (0.39 in) thick, 50 × 50 mm (1.97 × 1.97 in)

Refer to Table of Contents for specific component removal and installation information. G
INSTRUMENT PANEL
Most incidents are caused by contact and movement between:
1. The cluster lid A and instrument panel
H
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
BL
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint
J
These incidents can usually be located by tapping or moving the components to duplicate the noise or by pressing on the components while driving to stop the noise. Most of these incidents can be repaired by applying felt cloth tape or silicon spray (in hard to reach areas). Urethane pads can be used to insulate wiring har- K ness.
CAUTION: Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will L not be able to recheck the repair.
CENTER CONSOLE
Components to pay attention to include:
M
1. Shifter assembly cover to finisher
2. A/C control unit and cluster lid C
3. Wiring harnesses behind audio and A/C control unit
The instrument panel repair and isolation procedures also apply to the center console.
DOORS Pay attention to the: 1. Finisher and inner panel making a slapping noise 2. Inside handle escutcheon to door finisher 3. Wiring harnesses tapping 4. Door striker out of alignment causing a popping noise on starts and stops Tapping or moving the components or pressing on them while driving to duplicate the conditions can isolate many of these incidents. You can usually insulate the areas with felt cloth tape or insulator foam blocks from the Nissan Squeak and Rattle Kit (J-43980) to repair the noise.

SQUEAK AND RATTLE TROUBLE DIAGNOSIS
TRUNK Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner. In addition look for: 1. Trunk lid dumpers out of adjustment 2. Trunk lid striker out of adjustment 3. The trunk lid torsion bars knocking together 4. A loose license plate or bracket Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) causing the noise.
SUNROOF/HEADLINING Noises in the sunroof/headlining area can often be traced to one of the following: 1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise 2. Sunvisor shaft shaking in the holder 3. Front or rear windshield touching headlining and squeaking Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when the noise is present. These conditions should be duplicated when verifying and isolating the cause of the noise. Cause of seat noise include: 1. Headrest rods and holder 2. A squeak between the seat pad cushion and frame 3. The rear seatback lock and bracket These noises can be isolated by moving or pressing on the suspected components while duplicating the conditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component or applying urethane tape to the contact area.
UNDERHOOD Some interior noise may be caused by components under the hood or on the engine wall. The noise is then transmitted into the passenger compartment. Causes of transmitted underhood noise include: 1. Any component mounted to the engine wall 2. Components that pass through the engine wall 3. Engine wall mounts and connectors 4. Loose radiator mounting pins 5. Hood bumpers out of adjustment 6. Hood striker out of adjustment These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or insulating the component causing the noise.

CAN Communication System Description
NIS00163
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- A
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2 B
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

OPERATED PROCEDURE
Power Door Lock Operation
BCM locks all doors with receiving LOCK signal from key fob. When an UNLOCK signal is sent from key fob once, driver's door will be unlocked. Then, if an UNLOCK signal is sent from key fob again within 5 seconds, all other door will be unlocked.
Hazard and Horn Reminder Power is supplied at all times q to horn relay terminal 2 q through 10A fuse (No. 32, located in the fuse and fusible link box). When BCM receives LOCK or UNLOCK signal from key fob with all doors closed, BCM sends horn chirp signal to IPDM E/R. IPDM E/R grounds horn relay q to horn relay terminal 1 q through IPDM E/R terminal 51, and q to BCM terminals 45 and 46 from hazard warning lamp system Horn relay is now energized, and hazard warning lamp flashes and horn sounds as a reminder. The hazard and horn reminder has C mode (horn chirp mode) and S mode (non-horn chirp mode).

CAN Communication System Description
NIS0016P
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

CAN Communication System Description
NIS0017E
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
POWER SUPPLY AND GROUND Power is supplied at all times q through 10A fuse [No. 21, located in the fuse block (J/B)] q to combination meter (security indicator lamp) terminal 21. Power is supplied at all times q through 50A fusible link (letter F , located in the fuse and fusible link box) q to BCM terminal 55. q through 10A fuse [No. 18, located in the fuse block (J/B)] q to BCM terminal 42 When ignition switch is ACC or ON position, power is supplied q through 10A fuse [No. 6, located in the fuse block (J/B)] q to BCM terminal 11. Ground is supplied q to BCM terminal 52 q through body grounds E13, E26 and M28.
INITIAL CONDITION TO ACTIVATE THE SYSTEM The operation of the vehicle security system is controlled by the doors and back door. To activate the vehicle security system, BCM must receive signals indicating the doors and back door are closed and the doors are locked by key fob. When a door is open, BCM terminals 12, 13, 62 or 63 receives a ground signal from each door switch. When front door LH is unlocked by power window main switch (door lock and unlock switch), BCM terminal 22 receives a signal from terminal 14 of power window main switch. When front door RH is unlocked by power window switch (passenger side) (door lock and unlock switch), BCM terminal 22 receives a signal from terminal 16 of front power window switch (passenger side). When front key cylinder switch is in UNLOCK position, ground is supplied q to power window main switch terminal 6 q through front key cylinder terminals 6 and 5 (without Intelligent Key) q through door key cylinder switch terminals 3 and 2 (with Intelligent Key) q through body grounds M14 and M78. Then power window main switch send unlock signal to BCM. When the back door is open, BCM terminal 58 receives a ground signal q through back door lock assembly terminal 3 and 4 q through body grounds B7 and B20.
VEHICLE SECURITY SYSTEM ALARM OPERATION The vehicle security system is triggered by q opening a door q opening the back door q detection of battery disconnect and connect. The vehicle security system will be triggered once the system is in armed phase, When BCM receives a ground signal at terminals 12, 13, 62 and 63 receives a signal from each door switch, 58 (back door switch). Power is supplied at all times q to horn relay terminal 2 q through 15A fuse (No. 32, located in the fuse and fusible link box). When the vehicle security system is triggered, ground is supplied intermittently to both headlamp relay and horn relay. When headlamp high relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied to headlamps (LH and RH) and horns (HIGH and LOW). The headlamps flash and the horn sounds intermittently. The alarm automatically turns off after 50 seconds, but will reactivate if the vehicle is tampered with again.

VEHICLE SECURITY (THEFT WARNING) SYSTEM
VEHICLE SECURITY SYSTEM DEACTIVATION To deactivate the vehicle security system, a door or the back door must be unlocked with the key or key fob. A When the key is used to unlock a door, BCM terminal 22 receives signal
q from terminal 14 of the power window main switch (door lock and unlock switch). When the BCM receives either one of these signals or unlock signal from key fob or key cylinder switch, the B vehicle security system is deactivated. (Disarmed phase)
PANIC ALARM OPERATION
C Remote control entry system may or may not operate vehicle security system (horn and headlamps) as
required.
When the remote control entry system is triggered, ground is supplied intermittently to both headlamp relay
and horn relay.
D
When headlamp relay (with built-in IPDM E/R) and horn relay are energized and then power is supplied to
headlamps (LH and RH) and horns (HIGH and LOW).
The headlamp flashes and the horn sounds intermittently.
E
The alarm automatically turns off after 30 seconds or when BCM receives any signal from key fob.
CAN Communication System Description
NIS00196
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul- F
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2 G
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

Read the Following Precautions When Repairing HSS: 1. Additional points to consider
q The repair of reinforcements (such as side members) by heating is not recommended since it may weaken the component. When heating is unavoidable, do not heat HSS parts above 550°C (1,022°F). Verify heating temperature with a thermometer. (Crayon-type and other similar type thermometer are appropriate.)
q When straightening body panels, use caution in pulling any HSS panel. Because HSS is very strong, pulling may cause deformation in adjacent portions of the body. In this case, increase the number of measuring points, and carefully pull the HSS panel.
q When cutting HSS panels, avoid gas (torch) cutting if possible. Instead, use a saw to avoid weakening surrounding areas due to heat. If gas (torch) cutting is unavoidable, allow a minimum margin of 50 mm (1.97in).
q When welding HSS panels, use spot welding whenever possible in order to minimize weakening surrounding areas due to heat. If spot welding is impossible, use M.I.G. welding. Do not use gas (torch) welding because it is inferior in welding strength.

q The spot weld on HSS panels is harder than that of an ordinary steel panel. Therefore, when cutting spot welds on a HSS panel, use a low speed high torque drill (1,000 to 1,200 rpm) to increase drill bit durability and facilitate the operation.
2. Precautions in spot welding HSS This work should be performed under standard working conditions. Always note the following when spot welding HSS: q The electrode tip diameter must be sized properly according to the metal thickness.
q The panel surfaces must fit flush to each other, leaving no gaps.
q Follow the specifications for the proper welding pitch.
