Supplemental Restraint System (SRS) “AIRBAG” and “SEAT BELT PRE-TENSIONER”

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along witha seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types ofcollision. The SRS system composition which is available to NISSAN MODEL R20 is as follows (The compo-sition varies according to the destination and optional equipment.):I For a frontal collision

The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seatbelt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.

I For a side collisionThe Supplemental Restraint System consists of front side air bag module (located in the outer side of frontseat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontalcollision), wiring harness, warning lamp (one of components of air bags for a frontal collision).

Information necessary to service the system safely is included in the RS section of this Service Manual.WARNING:I 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 should be per-formed by an authorized NISSAN dealer.

I 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 AirBag Module, see the RS section.

I Do not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses can be identified by yellow harness connector.

Wiring Diagrams and Trouble DiagnosesWhen you read wiring diagrams, refer to the following:I GI section, “HOW TO READ WIRING DIAGRAMS”I EL section, “POWER SUPPLY ROUTING” for power distribution circuitWhen you perform trouble diagnoses, refer to the following:I GI section, “HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSES”I GI section, “HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT”

PRECAUTIONS

Fusea. If fuse is blown, be sure to eliminate cause of problem before

installing new fuse.b. Use fuse of specified rating. Never use fuse of more than speci-

fied rating.c. Do not install fuse in oblique direction; always insert it into fuse

holder properly.d. Remove fuse for clock if vehicle is not used for a long period

of time.

Fusible LinkA melted fusible link can be detected by visual inspection. If itscondition is questionable, use circuit tester or test lamp.CAUTION:I If fusible link should melt, it is possible that critical circuit

(power supply or large current carrying circuit) is shorted.In such a case, carefully check and eliminate cause ofproblem.

I Never wrap periphery of fusible link with vinyl tape.Extreme care should be taken with this link to ensure thatit does not come into contact with any other wiring har-ness or vinyl or rubber parts.

Circuit Breaker InspectionFor example, when current is 30A, the circuit is broken within 8 to20 seconds.

CIRCUIT BREAKER (PTC THERMISTOR TYPE)The PTC thermistor generates heat in response to current flow. Thetemperature (and resistance) of the thermistor element varies withcurrent flow. Excessive current flow will cause the element’s tem-perature to rise. When the temperature reaches a specified level,the electrical resistance will rise sharply to control the circuit cur-rent.Reduced current flow will cause the element to cool. Resistancefalls accordingly and normal circuit current flow is allowed toresume.

System DescriptionThe headlamp system on vehicles for North Europe contains a daytime light control unit. The unit activatesthe following whenever the engine is running with the lighting switch in the OFF position:I Low beam headlampsI Parking, license, tail and illumination lampsPower is supplied at all timesI through 10A fuse (No. 34, located in the fuse and fusible link box)I to daytime light control unit terminal 1 andI through 40A fusible link (No. C, located in the fusible link and fuse box)I to ignition switch terminal 1.Power is also supplied at all timesI through 15A fuse (No. 36, located in the fusible link and fuse box)I to daytime light control unit terminal 5 andI to lighting switch terminal 5.Power is also supplied at all timesI through 15A fuse (No. 37, located in the fusible link and fuse box)I to daytime light control unit terminal 7 andI to lighting switch terminal 8.With the ignition switch in the ON or START position, power is suppliedI through 10A fuse [No. 11, located in the fuse block (J/B)]I to daytime light control unit terminal 12.With the ignition switch in the START position, power is suppliedI to daytime light control unit terminal 8.Ground is supplied to daytime light control unit terminal 10 through body grounds M33 and M754.

HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)When the lighting switch is turned to the 1st or 2nd position, power is suppliedI through lighting switch terminal 12,I to daytime light control unit terminal 3.Then daytime light will be canceled. And the lighting system operation will be the same as no daytime lightsystem.

DescriptionI The vertical direction of the headlamp projection can be adjusted from inside the vehicle to prevent the

headlamp beam axis from facing upward due to a change in the number of occupants and load conditionsin the vehicle.

I A little Electronic Control Unit (ECU) is incorporated in each actuator (one for each headlamp), whichcompares a signal voltage (Vsignal), coming from the headlamp aiming switch, with battery voltage (12V).The signal voltage varies with the position of the switch.Related to the difference in voltage the actuator rod will move more or less and adjust the headlamp beamangle accordingly.

Bulb ReplacementThe headlamp is a semi-sealed beam type which uses a replacablehalogen bulb. The bulb can be replaced from the engine compart-ment side without removing the headlamp body.I Grasp only the plastic base when handling the bulb. Never

touch the glass envelope.1. Disconnect the battery cable.2. Disconnect the harness connector from the back side of the

bulb.3. Pull off the rubber cap.4. Press end of the retaining pin together to release bulb.5. Remove the headlamp bulb. Do not shake or rotate the bulb

when removing it.6. Install the new bulb in reverse order of removal.

CAUTION:I Do not leave headlamp reflector without bulb for a long

period of time as dust, moisture, smoke, etc. may enter theheadlamp body and affect the performance of the head-lamp. Thus, the headlamp bulb should not be removedfrom the headlamp reflector until just before a replacementbulb is to be installed.

Aiming AdjustmentWhen performing headlamp aiming adjustment, use an aimingmachine, aiming wall screen or headlamp tester. For operatinginstructions, of any aimer, it should be in good repair, calibrated andused according to respective operation manuals supplied with theunit.For details, refer to the regulations in your own country.

Before performing aiming adjustment, check the following:a. Keep all tires inflated to correct pressures.b. Place vehicle and tester on one and same flat surface.c. See that there is noload in vehicle other than coolant,

engine oil filled up to correct level, full fuel tank and thedriver (or equivalent weight placed in driver’s position).

CAUTION:Be sure aiming switch is set to “0” when performing aimingadjustment on vehicles equipped with headlamp aiming con-trol.

NATS AUDIO LINK

DescriptionThe link with the NATS IMMU implies that the audio unit can basically only be operated if connected to thematching NATS IMMU to which the audio unit was initially fitted on the production line.Since radio operation is impossible after the link with the NATS is disrupted, the stolen audio unit is basicallyuseless since special equipment is required to reset the audio unit.Initialization process for audio units that are linked to the NATS IMMUNew audio units will be delivered to the factories in the “NEW” state, i.e. ready to be linked with the vehicle’sNATS. When the audio unit in “NEW” state is first switched on at the factory, it will start up communicationwith the vehicle’s immobiliser control unit (IMMU) and send a code (the “audio unit Code”) to the IMMU. TheIMMU will then store this code, which is unique to each audio unit, in its (permanent) memory.Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the audio unit code to the audiounit. Hereafter, the audio unit will operate as normal.During the initialization process, “NEW” is displayed on the audio unit display. Normally though, communica-tion between audio unit and IMMU takes such a short time that the audio unit seems to switch on directlywithout showing “NEW” on its display.Normal operationEach time the audio unit is switched on afterwards, the audio unit code will be verified between the audio unitand the NATS before the audio unit becomes operational. During the code verification process, “WAIT” isshown on the audio unit display. Again, the communication takes such a short time that the audio unit seemsto switch on directly without showing “WAIT” on its display.When the radio is lockedIn case of a audio unit being linked with the vehicle’s NATS (immobiliser system), disconnection of the linkbetween the audio unit and the IMMU will cause the audio unit to switch into the lock (“SECURE”) mode inwhich the audio unit is fully inoperative. Hence, repair of the audio unit is basically impossible, unless the audiounit is reset to the “NEW” state for which special decoding equipment is required.Clarion has provided their authorized service representatives with so called “decoder boxes” which can bringthe audio unit back to the “NEW” state, enabling the audio unit to be switched on after which repair can becarried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the“NEW” state as to enable re-linking the audio unit to the vehicle’s immobiliser system. As a result of the above,repair of the audio unit can only be done by an authorized Clarion representative.

Service instruction

Item Radio linked with IMMU and/or SECU

Battery disconnection No additional action required

Radio needs repair Repair needs to be done by authorised representative of radio manufacturer since radiocannot be operated unless it is reset to NEW state, using special decoding equipment

Replacement of radio by new part Radio is delivered in NEW state. If possible, the radio will automatically link up with theimmobiliser system. If this appears not possible, CATS code needs to be manually input

Transferring radio to another vehicle/replacement of radio by an “old” part

Radio needs to be reset to NEW state by authorised representative of radio manufac-turer

Replacement of IMMU by new part Radio will request for CATS code input prior to establishing the link with the IMMU

Replacement of IMMU by old part If a radio code has already been stored in memory of the IMMU, the radio cannot belinked to it. After switching on the radio, it will display “SECURE” after 1 minute. Opera-tion can only be established after resetting the ratio by an authorised representative ofradio manufacturer

CATS code input procedure1. Radio displays “CODE IN” after the power is switched ON.2. Enter CATS code (4-digits) by pressing the preset buttons (using 1 to 4).

Press the preset buttons for the necessary amount of times for the number of each digits.e.g. CATS code is “5432”Press No. 1 preset button for 5 timesPress No. 2 preset button for 4 timesPress No. 3 preset button for 3 timesPress No. 4 preset button for 2 times

3. Press the button.4. If the code is OK, the radio will power ON.

If the code is NG, the radio will be locked up as below. After the lock up, the radio will display “CODE IN”again.1st to 3rd attempt: The radio will be locked for 10 seconds after each attempt4th to 20th attempt: The radio will be locked for 60 minutes after each attemptOver 20th attempt: The radio will be locked completely

SPEED DEPENDENT VOLUME CONTROL

DescriptionIf activated, the radio output volume will be automatically adjusted to compensate for increased driving noisesat higher driving speeds. The radio receives a speed signal from the combination meter and selects the out-put volume.

System DescriptionNATS has the following immobilizer functions:I This version of NATS has dongle control unit to improve its anti-theft performance (RHD models). Dongle

control unit has its own ID which is registered into NATS IMMU. So if dongle unit is replaced, initializationmust be carried out.

I When malfunction of dongle unit is detected:The security indicator lamp illuminates for about 15 minutes after ignition switch is turned to ON.— When dongle control unit has a malfunction, and the indicator lamp is illuminated, engine can not be

started. However engine can be started only one time when security indicator lamp turns off in about15 minutes after ignition switch is turned to ON.

I Since only NATS ignition keys, whose ID nos. have been registered into the ECM and IMMU of NATS,allow the engine to run, operation of a stolen vehicle without a NATS registered key is prevented by NATS.That is to say, NATS will immobilize the engine if someone tries to start it without the registered key ofNATS.

I All of the originally supplied ignition key IDs have been NATS registered.If requested by the vehicle owner, a maximum of five key IDs can be registered into the NATS compo-nents.

I The NATS security indicator (NATS security ind.) blinks when the ignition switch is in “OFF” or “ACC”position. Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.

I When NATS detects trouble, the security indicator lamp lights up as follows.

I NATS trouble diagnoses, system initialization and additional registration of other NATS ignition key IDsmust be carried out using CONSULT-II hardware and CONSULT-II NATS software.Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-IIoperation manual, NATS.

I When servicing a malfunction of the NATS (indicated by lighting up of security Indicator Lamp) orregistering another NATS ignition key ID no., it may be necessary to re-register original key iden-tification. Therefore, be sure to receive all keys and the PIN code from vehicle owner.

THEFT WARNING SYSTEM

EL-243

System DescriptionOPERATION FLOWThe SECURITY indicator can be operated by both the IMMU (for NATS) and the TCU (for Theft Warning). Theflow chart shows both operations.

NEL624


EL-244

SETTING THE THEFT WARNING SYSTEM

Initial condition(1) Close all doors.(2) Close hood.

Pre-armed phase and armed phaseThe theft warning system turns into the “pre-armed” phase when hood and all doors are closed and locked bykey or multi-remote controller. (The security indicator lamp blinks intermittently for 30 seconds.)After about 30 seconds, the system automatically shifts into the “armed” phase (the system is set).

CANCELING THE SET THEFT WARNING SYSTEMWhen the following (a) or (b) operation is performed, the armed phase is canceled.(a) Unlock the doors with the multi-remote controller.(b) Insert key in ignition key cylinder and turn it to ON. Then NATS IMMU will send a disarm signal to the time

control unit.

ACTIVATING THE ALARM OPERATION OF THE THEFT WARNING SYSTEMMake sure the system is in the armed phase. When the following operation (a) (b) (c) or (d) is performed, thesystem sounds the horns and flashes the hazard lamp for about 30 seconds.(a) Engine hood or any door is opened before unlocking door with the multi-remote controller.(b) A door is unlocked without using the multi-remote controller.(c) The ignition is switched ON without using a NATS registered key.(d) The ultrasonic sensing is triggered.

POWER SUPPLY AND GROUND CIRCUITPower is supplied at all times.I Through 10A fuse [No. 16 , located in the fuse block (J/B)]I to combination meter (security indicator lamp) terminal q27 .I through 10A fuse [No. 5 , located in the fuse block (J/B)]I to time control unit terminal U09 .With the ignition switch in the ON or START position, power is suppliedI through 10A fuse [No. 26 , located in the fuse block (J/B)]I to time control unit terminal U01 .Ground is suppliedI to time control unit terminal U16

I through body grounds F36 and F47 (LHD models), or M33 and M754 (RHD models).

INITIAL CONDITION TO ARM THE SYSTEMThe operation of the theft warning system is controlled by all the doors and hood.To activate the theft warning system, the time control unit must receive signals indicating all the doors andhood are closed and the doors are locked.When a door is open, time control unit terminal U06 or U07 receives a ground signal from each door switch.When a door is unlocked, time control unit terminal U25 , U35 or U36 receives a ground signal from each doorunlock sensor.When the hood is open, time control unit terminal U32 receives a ground signalI from the hood switchI through body grounds M33 and M754 .

THEFT WARNING SYSTEMSystem Description (Cont’d)

EL-245

THEFT WARNING SYSTEM ARMING (With key or remote controller used to lock doors)If the key is used to lock doors, time control unit terminal U29 receives a ground signalI from terminal q2 of the key cylinder switchI through body grounds B18 and B10 .If this signal or lock signal from remote controller is received by the time control unit, the theft warning sys-tem will arm automatically.When arming the theft warning system, time control unit terminal U18 supplies ground intermittently to termi-nal q40 of the combination meter. The security lamp will blink intermittently for approximately 30 seconds (andthen blink every 2.6 seconds, due to NATS).Now the theft warning system is in armed phase.

THEFT WARNING SYSTEM ALARM OPERATIONThe theft warning system is triggered byI opening a doorI opening back doorI opening the hoodI unlocking door without using the multi-remote controllerI switching the ignition ON without a NATS registered keyI triggering the ultrasonic sensorsOnce the theft warning system is in armed phase, if the time control unit receives a signal at terminal U25 ,

U35 , U36 (door unlock sensor), U06 , U07 (door switch), U32 (hood switch), or U30 (ultrasonic sensor) the theftwarning system will be triggered. The hazard lamps flash and the horn sounds intermittently.Power is supplied at all timesI through 10A fuse [No. 16 , located in the fuse block (J/B)]I to theft warning horn relay.If the theft warning system is triggered, ground is suppliedI from terminal U43 of the time control unitI to theft warning horn relay.The hazard lamps flash and the horn sounds intermittently.The alarm automatically turns off after 30 seconds but will reactivate if the vehicle is tampered with again, orif the initial cause remains present.

THEFT WARNING SYSTEM ALARM DISARMINGThe theft warning system alarm operation can be deactivated by either unlocking the vehicle with the remotecontroller, or turning the ignition to the “ON” position with a registered NATS key.

Trouble DiagnosesAlarm Trigger FeedbackTo verify the last three triggers that activated the theft warning system, the Time Control Unit (TCU) can beswitched into Diagnostic Mode (see page EL-218 how to enter Diagnostic Mode).Approximately 2 seconds after the TCU has finished flashing the hazard lamp to confirm that the DiagnosticMode has been successfully entered, the TCU will generate a short beep indicating the trigger that will be dis-played. A single beep means the most recent trigger, three beeps means the oldest trigger. Following eachbeep or group of beeps, the hazard lamp will flash to indicate the alarm trigger.

Source of Alarm Trigger Number (of flashes)

Driver’s door lock status switch 1

Passenger door lock status switch 2

Rear door lock status switch 3
