Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

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 SUPPLEMENTAL RESTRAINT SYSTEM and SEAT BELTS articles.

Precautions

1. Disconnect both battery cables in advance.
2. Never tamper with or force air bag lid open, as this may adversely affect air bag performance.
3. Be careful not to scratch pad and other parts.
4. When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may get in the way with cloth.
5. When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
6. Keep removed parts protected with cloth.
7. If a clip is deformed or damaged, replace it.
8. If an unreusable part is removed, replace it with a new one.
9. Tighten bolts and nuts firmly to the specified torque.
10. After re-assembly has been completed, make sure each part functions correctly.
11. 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.

1. Do not use any organic solvent, such as thinner or benzine.

CUSTOMER INTERVIEW

Interview the customer if possible, to determine the conditions that exist when the noise occurs. Use the Diagnostic Worksheet during the interview to document the facts and conditions when the noise occurs and any customer's comments; refer to " DIAGNOSTIC WORKSHEET ". This information is necessary to duplicate the conditions that exist when the noise occurs.

1. 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).
2. 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.
3. 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.
4. Squeak -(Like tennis shoes on a clean floor) Squeak characteristics include the light contact/fast movement/brought on by road conditions/hard surfaces = higher pitch noise/softer surfaces = lower pitch noises/edge to surface = chirping.
5. 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.
6. 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.
7. Knock -(Like a knock on a door) Knock characteristics include hollow sounding/sometimes repeating/often brought on by driver action.
8. 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.
9. Thump-(Heavy, muffled knock noise) Thump characteristics include softer knock/dead sound often brought on by activity.
10. Buzz-(Like a bumble bee) Buzz characteristics include high frequency rattle/firm contact.
11. 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.
12. Weather conditions, especially humidity and temperature, may have a great effect on noise level.

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.

REPAIR THE CAUSE

1. If the cause is a loose component, tighten the component securely.
2. If the cause is insufficient clearance between components

1. separate components by repositioning or loosening and retightening the component, if possible.
2. 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.

CONFIRM THE REPAIR

Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same conditions as when the noise originally occurred. Refer to the notes on the DIAGNOSTIC WORKSHEET .

INSTRUMENT PANEL

Most incidents are caused by contact and movement between

1. The cluster lid A and instrument panel
2. Acrylic lens and combination meter housing
3. Instrument panel to front pillar garnish
4. Instrument panel to windshield
5. Instrument panel mounting pins
6. Wiring harnesses behind the combination meter
7. A/C defroster duct and duct joint 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 silicone spray (in hard to reach areas). Urethane pads can be used to insulate wiring harness. CAUTION: Do not use silicone spray to isolate a squeak or rattle. If you saturate the area with silicone, you will not be able to recheck the repair.

CENTER CONSOLE

Components to pay attention to include

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.

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 bumpers 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.

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. Sun visor shaft shaking in the holder
3. Front or rear windshield touching headliner 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.

OVERHEAD CONSOLE (FRONT AND REAR)

Overhead console noises are often caused by the console panel clips not being engaged correctly. Most of these incidents are repaired by pushing up on the console at the clip locations until the clips engage.

In addition look for

1. Loose harness or harness connectors.
2. Front console map/reading lamp lens loose.
3. Loose screws at console attachment points.

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.

OUTLINE

Electric sunroof system consists of

1. Sunroof switch
2. Sunroof motor assembly
3. BCM (body control module)

BCM supplies power to the sunroof motor. Sunroof operation depends on sunroof switch condition.

ANTI-PINCH FUNCTION

The CPU (central processing unit) of sunroof motor assembly monitors the sunroof motor operation and the sunroof position (fully-closed or other) by the signals from sunroof motor.

When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof switch controls the motor for open and the sunroof will operate until it reaches full up position (during tilt down operation) or 125 mm (4.92 in) or more in an open direction (during slide close operation).

1. close operation and tilt down when ignition switch is in the ON position.
2. close operation and tilt down during retained power operation.

The CPU of the sunroof motor assembly also monitors vehicle speed in order to determine when additional force is needed to overcome the inherent drag characteristics of a vehicle moving in excess of approximately 97 km/h (60 MPH). Drag created by the wind on the sunroof at higher speeds could cause the sunroof to not close properly without compensation from the CPU of the sunroof motor assembly.

INITIALIZATION FAILURE CONDITIONS

Initialization and teaching of system should be conducted if the following conditions exist

1. sunroof will only move in the UP/CLOSE direction, having a step by step motion
2. sunroof does not have any auto operation.

INITIALIZATION PROCEDURE

If the sunroof does not close or open automatically, use the following procedure to return sunroof operation to normal.

1. Press the switch to the UP/CLOSE position to tilt the sunroof up fully. When the sunroof reaches the full tilt up position it will back up a few millimeters and stop.
2. Release the UP/CLOSE switch.
3. Within 5 seconds of releasing the UP/CLOSE switch, press and hold the UP/CLOSE switch again. The sunroof will move to the full open position and back to the closed position. NOTE: If the UP/CLOSE switch is released anytime during this teaching process, all learned profile data will be discarded and the procedure will have to be started over.
4. Release the UP/CLOSE switch. Do not disconnect power for at least two seconds. The sunroof is now initialized and taught. Initializing procedure is complete. Confirm proper operation of the sunroof (slide open, slide closed, tilt up, tilt down).

RE-TEACHING CONDITIONS

Re-teaching of system should be conducted if any of the following conditions exist

1. the sunroof is manually operated using the sunroof wrench with the battery dead or disconnected.
2. the sunroof is manually operated using the sunroof wrench with the key switch in the OFF position and retained power timed out [after approximately 45 seconds (mode 1) or 2 minutes (mode 3) or with a front door open].
3. the sunroof motor assembly is replaced with a new one.
4. the sunroof motor is removed from the sunroof assembly and operated before it is reinstalled.
5. the sunroof motor is removed from the sunroof assembly and the glass panel position is changed.

RE-TEACHING PROCEDURE

1. Using the UP/CLOSE switch, move the sunroof toward the tilt position until it stops.
2. Release the UP/CLOSE switch.
3. Press the UP/CLOSE switch again and continuously hold. The sunroof will begin to move in about 10 seconds.
4. Continue to hold the UP/CLOSE switch while the sunroof moves in a jogging motion to the full tilt position. When the sunroof reaches the full tilt position, it will back up a few millimeters and stop.
5. Release the UP/CLOSE switch.
6. Within 5 seconds of releasing the UP/CLOSE switch, press and hold the UP/CLOSE switch again. The sunroof will move to the full open position and back to the closed position. NOTE: If the UP/CLOSE switch is released anytime during this teaching process, all learned profile data will be discarded and the procedure will have to be started over.
7. Release the UP/CLOSE switch. Do not disconnect power for at least two seconds. The sunroof is now retaught.
