Beforeinstallingthe retractor,checkthat the seat belt can be pulledout freely.

2. Make sure that the seat belt does not lockwhen the retractor(A) is leanedslowly up to 15'from the mounted position.The seat belt should lockwhen the retractoris leanedover 40'. Do not attemptto disassemblethe retractor.

After installingthe anchors,checkfor free movementon the anchorbolts.lf necessary, removethe anchorbolts and checkthat the washersand other partsare not damagedor improperlyinstalled. 3. Checkthe seat beltsfor damageor discoloration. Cleanwith a shop towel if necessary.Use only soap and water to clean. NOTE:Dirt build-upin the loops of the upper anchorscan causethe seat beltsto retractslowly. Wipe the insideof the loops with a cleancloth dampenedin isopropylalcohol. 4. Checkthat the seat belt does not lockwhen pulled out slowly. The seatbelt is designedto lock only during a suddenstop or imPact.

Exceptwhenperformingelectricalinspections, alwaysturn the ignition switch OFF,disconnectthe negativecablefrom the battery,and wait at least3 minutes beforebeginningwork. NOTE:The memory is not erasedeven if the ignition swiich is turned OFFor the batterycablesare disconnectedfrom the battery. . Use replacementpartswhich are manufacturedto the same standardsand quality as the original parts.Do not install used SRS partsfrom anothervehicle.Use only new partswhen making SRS repairs.

. Use only a digital multimeterto checkthe system lf it is not a Hondamultimeter,make sure its output is 10 mA {0.01A) or lesswhen switchedto the lowestvalue in the ohmmeter range.A testerwith a higheroutput could causeaccidentaldeploymentand possible injury. . Do not put objectson the passenger'sairbag. . The original radio has a coded theft protectloncircuit. Be sureto get the customer'sradio code and write down the frequenciesfor the radio presetstations beforedisconnectingthe batterycable. . Beforereturningthe vehicleto the customer,enter the customer'sradio code,and radio stationpreset, and set the clock.

Steering-relatedPrecautions CableReelAlignment

. Carefullyinspectany SRSpart beforeyou installit. Do not installany part that shows signsot being droppedor improperlyhandled,such as dents,cracks, or deformation.

. M i s a l i g n m e not f t h e c a b l er e e lc o u l dc a u s ea n o p e ni n the wiring, makingthe SRSsystemand the horn inoperative.Centerthe cable reel wheneverthe following is performed(seestep 6 on page 23-73). -

. Do not dlsassemblethe cable reel. . Do not apply greaseto the cable reel. . lf the cable reel shows any signs of damageor contamination,replaceit with a new one. For example,it does not rotatesmoothly. Beforeremoving any of the SRSparts (including disconnectionof the connectors),alwaysdisconnect the SRSconnector.

Wring Precautions

Precautionsfor ElectricalInspections

Some of the SRSwiring can be identifiedby a special yellow outer covering,and the SRSconnectorscan be identifiedbv their vellow color. Observethe instructionsdescribedin this section.

. When using electricaltest equipment,insertthe Drobeof the tester into the wire side of the connector. Do not insertthe Drobeof the tester into the terminal side of the connector,and do not tamper wlth the connecror.

. Never attemptto modify. splice,or repairSRSwiring. l f t h e r ei s a n o p e no r d a m a g ei n S R Sw i r i n g ,r e p l a c e the harness.

Use a U-shapedprobe.Do not insertthe probe fo rcibly.

Besureto installthe harnesswiresso theydo notget pinched, or interfere with otherpans.

. Make sure all SRSground locationsare clean,and groundsare securelyfastenedfor optimum metal-tometal contact.Poorgroundingcan causeintermittent problemsthat are difficultto diagnose.

sRs Precautionsand Procedures(cont'd) LockConnector Spring-loaded

BackprobingSpring-loadedLockConnectors

Some SRSsystem connectorshave a spring-loaded lock.

When checkingvoltageor resistanceon this type of connectorthe first time, vou must removethe retainer (A)to insertthe tester probe from the wire side.

Disconnecting To releasethe lock,pullthe spring-loadedsleeve(A) toward the stop {B)while holdingthe oppositehalf of the connector.Then pull the connectorhalvesapart. Be sure to Dullon the sleeveand not on the connector.

Connecting 1. To reconnect,hold the pawl-sideconnector,and oresson the backof the sleeve-sideconnectorin the directionshown. As the two connectorhalves are pressedtogether,the sleeve(A) is pushed back by the pawl (C).Do not touch the sleeve.

When the connectorhalvesare completely connected,the pawl is released,and the springloadedsleevelocksthe connector.

NOTE:lt is not necessaryto reinstallthe removed retainer;the terminalswill stay lockedin the connector h o u si n o .

To removethe retainer{A), inserta flat-tip screwdriver(B) betweenthe connectorbody and the retainer,then carefullypry out the retainer.Takecare not to breakthe connector.

To erasethe DTC(S) from the SRSunit, use a Honda PGM Tester(seethe HondaPGM TesterSRSVehicle SystemSupplement)or the following procedure. 1 . M a k es u r et h e i g n i t i o ns w i t c hi s O F F . 2. Connectthe specialtool (A)to the MES 2P connector(B).Do not use a jumper wire.

After checkingthe DTC,troubleshootas follows: "Readingthe DTC"). 1. Readthe DTC(see "Erasingthe DTC 2. Erasethe DTCmemory (see Memory"). 3. With the shift lever in neutral,startthe engine,and letit idle. The SRSindicatorwill come on for about 6 seconds and then go off. Shakethe wire harnessand the connectors,take a test drive (quickacceleration,quick braking, cornering),turn the steeringwheel fully left and right,and hold ittherefor 5to 10 seconds.lf the problem recurs,the SRSindicatorwill come on. lf you can't duplicatethe intermittentfailure,the svstem is oK at this time.

sRs SystemDescription SRSComponents Airbags The SRS is a safetydevicewhich, when usedwith the seat belt, is designedto help protectthe driver and passengerin a frontal impact exceedinga certainset limit. The system consistsofthe SRS unit, includinga safingsensorand an impact sensor(A),the cable reel (B).the driver's airbag (C)and the passenger'sairbag (D). Seat Belt Tensioners The seat belt tensioner1E)is linkedwith the SRSairbagsto further increasethe effectivenessof the seat belt. In a front-endcollision,the tensionerinstantlyretractsthe belt firmly to securethe occupantsin their seats.

SRS Operation The main circuit in the SRSunit sensesand judgesthe force of impact and, if necessary,ignitesthe inflatorcharges.lf batteryvoltage is too low or power is disconnecteddue to impact,the voltageregulatorand the back-uppower circuit respectivelywill keepvoltageat a constantlevel. For the SRS to operate: (1)The impact sensormust activateand send electronicsignalsto the microprocessor. {2)The microprocessormust computethe signalsand send them to the airbag inflators(and seat belttensioners). {3)The inflatorsmust ignite and deploy the airbags(and activatethe tensioners).

Self-diagnosis System A self-diagnosiscircuit is built into the SRS unit; when the ignition switch is turned ON (ll),the SRSindicatorcomes on and goes off after about 6 secondsif the SRSis operatingnormally. lf the indicatordoes not come on, or does not go off after 6 seconds,or if it comes on while driving, it indicatesan a n d r e p a i r e da s s o o na s p o s s i b l e . a b n o r m a l i t yi n t h e S R S .T h e S R Sm u s t b e i n s p e c t e d For betterserviceability,the SRSunit memory storesa DTCthat relalesto the causeof the malfunction,and the unit is connectedto the data link connector(DLC).This informationcan be readwith the Honda PGM Testerwhen it is connectedto the DLC(16P)(seepage 23-11).
