GENERAL

• The programmed restraint system (SRP ) limitsthe force of the belt on the body.

MAB11197S

All operations on the air bag and pretensionersystems must be carried out by qualified and trai-ned personnel.

These safety features are complementary.

In the event of a frontal impact of sufficientforce:

• the front seat belts retain the driver and pas-senger.

• The pretensioners tighten the front seat beltsin such a way that they flatten them against the body.

• The air bag cushions inflate :- from the centre of the steering wheel to pro-

tect the driver’s head,

- from the dashboard to protect the front pas-senger’s head (according to equipment).

WIRING Air bags, pretensioners and seat belts 88

NOTE :

Vehicles fitted with front air bags are identified by a sticker placed in the lower corners of thewindscreen on each side with the inscription "SRPair bag" in the centre of the steering wheel andon the dashboard (according to equipment).

Vehicles fitted with side air bags are identified bya sticker placed in the lower corners of the winds-creen on each side with the inscription"air bag"on the side of the front seat backs (according toequipment).

After each replacement of the windscreen, re-member to apply the stickers mentioning that thevehicle is fitted with air bags.

All of these stickers are available in a kit part number: 77 01 205 442.

15132R

In the event of a side impact of sufficient force,the corresponding side air bag (on the impactside) inflates on the door side, to protect the headand thorax of the seat occupant.

IMPORTANT:

• Do not put covers on the front seats.

• Do not put anything in the way which will ob-struct inflation of the air bags.

• In the event of work being carried out on thevehicle sill (on the side impact sensor, on the bodywork, on the seat belt inertia reel,...), theair bag unit must be locked using the faultfinding tool.

• Any operation involving removal and refittingof the seat trim on a seat back fitted with aside air bag, must not be carried out for thetime being.

In case of a fault on the air bag cushion or follo-wing its inflation, the whole seat must be repla-ced following the specific Parts Department or-der procedure .

Reminder : for vehicles fitted with self containedside air bags, refer to Technical Note 3064A.

IMPORTANT : the pyrotechnic systems (pretensio-ners, front and side air bags) must be checkedusing a fault finding tool :- following an accident in which the air bags

did not inflate,- following a theft or attempted theft of the ve-

hicle,- before selling a second hand vehicle.







SPECIAL TOOLING

These systems can have fault finding carried outusing the following fault finding tools :

• XR25 only for pretensioners and front air bags,

• NXR or OPTIMA 5800 for pretensioners andfront and side air bags (except self containedside air bags).

These tools allow faults in the computer or faultylines in the system to be detected (see the" FaultFinding " section).

NOTE : These tools have an additional functionwhich allows the trigger lines to be deactivated,to prevent triggering of the pyrotechnic gas gene-rators.

XRBAG TEST KIT (Elé. 1288)

This equipment is a specially designed tool fortesting and fault finding of air bag and seat beltpretensioner devices.

It allows electrical measurements to be made onthe various lines of the systems (see the " Faultfinding " section).

IMPORTANT : no measurements may be made onthese systems using an ohmmeter or any otherelectrical measuring equipment: the system may be triggered due to the operating current of themeasuring equipment.

14328S

This bornier is connected in place of the compu-ter.

Using the XRBAG , it allows all the trigger lines to be checked, the computer supply voltage to bemeasured and forces the air bag warning light onthe instrument panel to illuminate.

Terminals also allow continuity checks on the dia-gnostic lines, on the warning light lines and onthe supply to the computer (see "Fault Finding"section).

It has the same electrical specifications as a realignition module and is used to replace the air bagor the pretensioner during fault finding.

Refer to your After Sales Head Office for furtherinformation.

15749S







DESTRUCTION EQUIPMENT

In order to avoid any risk of an accident the pyro-technic gas generators for the air bags and seat belt pretensioners must be triggered before thevehicle or the part is scrapped.

Tool Elé. 1287 must be used which is provided forthis purpose.

96832R

Refer to " Destruction procedure " section.

IMPORTANT: do not trigger pretensioners whichmust be returned under warranty for a stalk pro- blem. This makes analysis of the component im-possible for the supplier.

Return the component in the packaging of thenew one.

OPERATION OF PRETENSIONERS AND FRONT AIRBAGS

When the ignition is switched on, the control war-ning light for these systems is illuminated for se-veral seconds and then is extinguished.

The computer is on standby and monitors the de-celeration of the vehicle using the signal measu-red by two integral decelerometers.

In the event of a frontal impact of sufficient force,one of them simultaneously triggers the pyrote-chnic generators for the two seat belt pretensio-ners.

Under the force of the gas generated by the sys-tem, a piston moves in its cylinder pulling a cableconnected to a corresponding central bucklewhich retracts the seat belt (see the"Pretensioners " section).

If the frontal impact is greater, the second elec-tronic decelerometer triggers the ignition of thepyrotechnic gas generators which inflate the dri-ver and passenger air bags (according to equip-ment).

These systems will not trigger in the event of:- a side impact,- a rear impact.

When triggered, a pyrotechnic gas generator pro-duces an explosion and a small amount of smoke.

NOTE : the computer and ignition modules supplynormally comes from the vehicle battery.However, an energy reserve is included in thecomputer in case the battery is disconnected atthe start of the impact.







OPERATION OF SIDE AIR BAGS

When the ignition is switched on, the control war-ning light for these air bag and pretensioner sys-tems is illuminated for several seconds and then isextinguished.

The air bag and pretensioner system computer isthen on standby as are the side air bags impactsensors located in the two inner sills of the vehicle.

In the event of a side impact of sufficient force,the side impact sensor on the impact side sends asignal to the air bag and pretensioner systemcomputer , after having had confirmation of animpact from the electronic safety sensor (incorpo-rated in the unit).

The unit triggers the ignition of the pyrotechnicgas generators in the seat which inflate the air bag cushion (on the impact side).

The side air bags are not triggered during:- a frontal impact,- a rear impact,- an impact on the opposite side.

When triggered, a pyrotechnic gas generator pro-duces an explosion and a small amount of smoke.

NOTE : the computer and ignition modules supplynormally comes from the vehicle battery.However, an energy reserve is included in thecomputer in case the battery is disconnected atthe start of the impact.

REMINDER : for vehicles fitted with self containedair bags, see Technical Note 3064A.

COMPUTER

Two types of computer are assembled on these ve-hicles according to their equipment :

• A unit supplied by a 30 track yellow connectorfor vehicles without side air bags. This must beconfigured according to the vehicle’s equip-ment (see configuration).

• A unit supplied by a 50 track orange connectorfor vehicles with side air bags.

These units comprise :- two electronic decelerometers for front air bags

and pretensioners,- an electronic safety sensor for non-self contai-

ned side air bags (unit with 50 track orangeconnector only),

- connections with side electronic sensors in theinner sills (unit with 50 track orange connectoronly),

- an ignition circuit for the different pyrotechnicsystems ,

- an energy reserve,- a fault finding circuit with memorisation of the

faults detected,- a control circuit for the warning light on the ins-

trument panel,- a communication interface K - L via the fault fin-

ding socket.

IMPORTANT

Before removing the computer, it must be lockedusing one of the fault finding tools (XR25, NXR orOPTIMA 5800 ).

When this operation is activated,all the ignitionlines are inhibited and the air bag warning light onthe instrument panel is illuminated (new computersare delivered in this condition).

See following procedure.







Special features after triggering

These types of unit (30 or 50 track) can accept upto four triggerings maximum. Therefore it is notnecessary to replace them each time the air bagsor pretensioners are triggered .

In the event of being triggered, the warning lighton the instrument panel is illuminated, but thecomputer does not lock the ignition lines whichhave not been triggered. These remain in opera-tion.

On the other hand, the computer locks the memo-rised faults in order to prevent accidental erasingof the context register for the impact which cau-sed triggering.

These contexts can later be used to simplify therepair of the vehicles involved in accidents and al-so for examination needs.

IMPORTANT , during repair following an impact,an unlocking command must be carried out follo-wed by a locking command for the computer tolock all of the ignition lines.

Erasing memorised faults is only possible follo-wing a computer unlocking command.

If the fault finding tool does not recommend re-placing the computer, only replace the triggeredcomponents and check that there are no faults.

When everything is correct, unlock the computerusing a fault finding tool; the system is again ope-rational.

If the fault finding tool recommends replacing thecomputer, it will indicate either :

• that the computer has triggered four times ei-ther just the pretensioners or the pretensio-ners and air bags or the side air bag which isnot self contained (according to equipment),

• or an internal fault in the computer .

In these two circumstances, replace the computer.

Special notes for replacing the computer

A new computer must be fitted to the vehicle be-fore reconnecting its connector (tightening tor-que : 0.8 daN.m ).

The arrow on the computer must point towardsthe front of the vehicle.

After connecting the connector, carry out a checkusing the fault finding tool and proceed withconfiguration if the vehicle does not have a pas-senger air bag.

When everything is correct, unlock the computerusing a fault finding tool; the system is again ope-rational.







Procedure for locking the computer

Before removing the computer or before carryingout any repair on the air bag or pretensioners sys-tem, the computer must be locked either :

• by using the XR25 (fiche n ° 48)1 Type in code D49 ISO selector on S82 Type in command G80*

When this operation is activated, all theignition lines are inhibited, the air bagwarning light on the instrument paneland bargraph 16 LH side on the XR25 areilluminated (new computers are deliveredin this condition).Fault finding remains possible when thismode is activated.

NOTE : to unlock the computer, use the same me-thod using command G81*. The air bag warninglight on the instrument panel and bargraph 16 LHside on the XR25 will be extinguished.

• by using the NXR and the OPTIMA 58001 Choose the " fault finding " menu2 Select and validate the vehicle type (Clio

II)3 Select and validate the "Air bag and pre-

tensioners" system which is to have faultfinding carried out

4 Choose the " Command " menu5 Select and validate the "Actuator

Command " operation then validate the"computer locking " command.

6 Choose the " Status " menu and check thatthe computer is correctly locked. The bar-graph for the " locked computer" line andthe air bag warning light on the instru-ment panel must be illuminated (newcomputers are delivered in this condition).Fault finding remains possible when thismode is activated.

NOTE : to unlock the computer, use the same me-thod validating the " Computer unlocking " line.The bargraph for the " Computer locked " line andthe air bag warning light on the instrument panelmust be extinguished.

Removal

It is located on the tunnel in the central console.

To access it :- remove the central console,- move the warm air ducts to one side and dis-

connect the computer,- cut the carpet slightly to access the mounting

bolts,- remove the computer with the diagnostic

IMPORTANT: The pyrotechnic systems (pretensio-ners or air bags) must not be handled when near aheat source or a flame because there is a risk thatthe system will be triggered.

IMPORTANT : Before removing a passenger air bag module, lock the computer using the faultfinding tool.

When this operation is activated, all of the trigge-ring lines are inhibited, the air bag warning lighton the instrument panel is illuminated.

To remove the passenger air bag module the up-per part of the dashboard must be removed.

Remove:- the windscreen pillar trim sections,- the half cowlings under the steering wheel- the mounting bolts on the upper part of the

dashboard and release it (for more details see"section 83 in MR 337 ").

Disconnect the ignition module.

The passenger air bag module is mounted by six bolts.

14092R1

IMPORTANT : In the event that the passenger air bag module should be triggered, the deforma-tion of the mountings (microcracks) means themetal dashboard support beam must be replaced.







Special case : the connector with lugs

A series of vehicles are fitted with a red connectorwith lugs (A) on the passenger air bag module.

16008R

To disconnect it, carefully use a small screwdriveras a lever , so as not to damage the lugs .

In the event of the lugs breaking, replace theconnector using the kit part number : 77 01 206210 using the following method.

After deactivating the air bag function using thefault finding tool and removing the passenger air bag module :

• cut the passenger air bag wiring 60 mm fromthe instrument panel wiring tape,

• unsheath the passenger air bag supply wiring by 30 mm ,

• strip the wiring provided in the kit and thepassenger air bag wiring by approximately 10mm ,

• thread 2 cm of heat shrink sleeving (providedin the kit) on each of the vehicle’s wiring lines,

15668R

• refit and secure the passenger air bag module,

• connect the new connector to the passengerair bag module,

• carry out a check using the fault finding tool.

Unlock the computer if everything is correct,otherwise see the " Fault Finding " section.

• solder the vehicle’s wiring to the wiring in thekit (B),

• position the heat shrink sleeving over the sol-dered joins and heat it,







Refitting

IMPORTANT: the safety notes which must be fol-lowed to refit or replace the passenger air bagmodule must be observed .

If these procedures are not correctly observed thesystems may not operate correctly or may be acci-dentally triggered, presenting a danger to the oc-cupants of the vehicle.

Refitting is the opposite of removal

IMPORTANT: a 2nd generation passenger air bagmodule must not be fitted to a vehicle fitted witha 1 st generation computer (see the table onpages 2 and 3).Observe part numbers mentioned in the spareparts catalogue, referring to vehicle equipment.

REMINDER: the computer in these vehicles can wi-thstand several triggerings. Therefore, it does nothave to be replaced after every triggering of theair bag(s) or pretensioners (see "Computer" sec-tion).

IMPORTANT

• No foreign body (bolt,clip...) must be forgottenwhen refitting the air bag module.

• Reconnect the passenger air bag module andsecure it (tightening torque : 0.6 daN.m ).

• Press the connector in firmly on the moduleside (strong clipping system).

• Attach a blue adhesive sticker " after sales sys-tem tamperproof label " sold under part number : 77 01 205 356 on the air bag moduleconnector.

• After refitting everything, carry out a checkusing the fault finding tool.

• Unlock the computer if everything is correct,otherwise see the"Fault Finding" section.

SIDE AIR BAG MODULE

Description

It is fitted into the seatback of the front seats onthe door side.

It comprises :- an inflatable bag,- a pyrotechnic gas generator and ignition

module.

These components cannot be separated.

15132R

In order to work the inflatable bag tears throughthe module cover, the foam and the seat trim.

NOTE: this system is operational after the ignitionhas been switched on.

IMPORTANT: The pyrotechnic systems (pretensioners or air bags) must not be handled when near a heatsource or a flame because there is a risk that thesystem will be triggered.

No measurements may be made on these systemsusing an ohmmeter or any other electrical measu-ring equipment: the system may be triggered dueto the operating current of the measuring equip-ment.







Removal - Refitting

Any operation involving removal and refitting of the seat trim of a seat back fitted with a side air bag, must not be carried out for the time being.

In case of a fault on the air bag cushion or follo-wing its inflation, the whole seat must be repla-ced following the specific Parts Department or-der procedure .

REMINDER: the computer in these vehicles can wi-thstand several triggerings. Therefore, it does nothave to be replaced after every triggering of theair bag(s) or pretensioners (see "Computer" sec-tion).

On the other hand, in the event of a triggering being caused, the side impact sensor must be re-placed (certain components lose their nominalspecifications after the triggering energy has pas-sed through them).

IMPORTANT :

• Before removing a seat, lock the computerusing the fault finding tool.When this operation is activated, all the trig-gering lines are inhibited and the air bag war-ning light on the instrument panel is illumina-ted.

• When refitting, after replacing the seat andreconnecting the connectors, carry out a checkusing the fault finding tool. Unlock thecomputer if everything is correct, otherwisesee the"Fault Finding" section.

IMPORTANT : before scrapping an untriggered air bag module, it MUST be destroyed in accordancewith the method described in the "DestructionProcedure" section

96832R

DESTRUCTION PROCEDURE

To avoid the risk of an accident, the pyrotechnicgas generators must be triggered before scrap-ping a vehicle or a single part.

Tool Elé . 1287 must be used.







• Pretensioners

IMPORTANT: do not trigger pretensioners whichmust be returned under warranty for a stalk pro- blem. This makes analysis of the component im-

possible for the supplier.

Return the component in the packaging of thenew one.

Destruction of the part fitted to the vehicle

Move the vehicle outside the workshop.

Connect the destruction tool to the pretensionerafter removing the seat runner cover.

1AB8651.0

This fault finding section comprises two parts :

- For systems only with front air bags marked "Front".- For systems with front and side air bags marked "Side".

CONDITIONS FOR APPLYING THE CHECKS DEFINED IN THIS FAULT FINDING

In this fault finding, each fault is interpreted for a type of special memory (fault present, fault memorised,fault present or memorised).The checks defined for the processing of each fault are therefore only applied to a vehicle if the fault isinterpreted for the type of fault declared by the fault finding tool.

If a fault is only interpreted in this fault finding if it is declared "present", applying the fault finding whenthe fault is only "memorised" does not enable the origin of memorising this fault to be located. In thiscase, only a check of the wiring and the connections for the part at fault needs to be carried out (it ispossible to test the wiring concerned in fault finding mode in order to try to see the change frommemorised fault to fault present).

If a fault is interpreted when it is declared"memorised", the conditions for confirming the actual presenceof the fault (and the need to apply fault finding) appear in the "Notes" section or at the beginning of thefault interpretation.

Note : the ignition must be switched off before operating the fault finding tool.

TOOLING REQUIRED FOR OPERATIONS ON THE AIR BAG AND SEAT BELT PRETENSIONER SYSTEMS :

- fault finding tool (except XR25).- XRBAG update N ° 4 for front air bags (with the 30 track B40 adaptor with yellow computer base).- XRBAG update N ° 5 for side air bags ( with the new 50 track B50 adapter with orange computer base).

REMINDERS :

When carrying out an operation on the air bag / seat belt pretensioner systems, the computer must belocked using the fault finding tool to prevent any risk of incorrect triggering (all trigger lines will beinhibited).This "locked" mode is indicated by illumination of the warning light on the instrument panel.

If the operati on fol low s an im pact during w hich t he pretensioners and/or air bagsw ere tri ggered, locking w il l only be possible foll ow ing a computer unl ocki ng command.

Foll ow i ng an impact duri ng whi ch the pret ensioners and/or ai r bags w ere t ri ggered, erasing t he memori sed fault s wi ll only be possible follow ing a computer unlocking command.

Never take measurements on the air bag and pretensioner triggering lines with an apparatus other thanthe XRBAG.Before using a dummy ignition module, ensure that its resistance is between 1.8 and 2.5 ohms.During an operation ensure that the computer supply voltage does not fall below 10 volts (#01).
