ServicePrecaution AdhesiveWheelBalanceWeight The wheels of this model are not designedto mount the balanceweight on the outer side of the wheel. Instead,mount the self-adhesivebalanceweight on the inner side of the wheels. Note the following servicetips and installthe weights securely. . Use only self-adhesivewheel balanceweights to balancethe wheels of the car. . The wheels and weight must be 41.F (5"C)or above during installation. . Do not damagethe wheel when removingthe balanceweight, ' After removingthe balanceweighl, removethe adhesiveresiduefrom the wheel using a degreasingcreantngagenr. ' R e m o v e d u s t a n d f o r e i g n m a t e r i af lr o m t h e s u r f a c eo f t h e w h e e la n d d e g r e a s e t h e s u r f a c eb e f o r ea p p l y i n gt h e n e w balanceweight. ' Use the IPA (isopropylalcohol)or brakecleanerasthe degreasingagent,and letthe surlacedrythoroughly after degreasing. ' Peeloff the backingfrom the balanceweight with care,do not touch the adhesivesurface.Placethe balanceweight on the wheel lengthwiseto the wheel. 'Presstheentiresurfaceofthebalanceweightwith5toTkgofforcesothebalanceweight'stapeadherestothe wheel securely. . Rockthe balanceweight lightly and make sure that it is properlysecuredto the wheel. . Do not placeone balanceweight on top of another. ' When you cannot measurethe amount of weight at the adhesionpositionwith the wheel balance machine,ta ke the amount of unbalanceat the outer rim and calculatethe amount of weight usingthe conversionfactor betow. Selectthe balanceweight that is the closestto the calculation. Conversionfactorfor the adhesionposition: Frontwheel:2.9 R e a rw h e e l : 2 . 5 Example: lf the unbalanceat the front rim is 15 grams, it is calculatedas ; 1Sx 2.9 = 43.5gr. Therefore,the unbalanceis 43.5grams.
There must be clearance.

GeneralTroubleshootingInformation lntermittent Failures
'02-03 models:
The term "intermittentfailure" meansa system may have had a failure,but it checksOK now. lf the MalfunctionIndicatorLamp (MlL)on the dash does not come on, checkfor poor connectionsor loosewires at all connectorsrelatedto the circuitthat vou are troubleshooting.
Opensand Shorts "Open"
and "Short" are common electricalterms.An open is a breakin a wire or at a connection,A short is an accidentalconnectionof a wire to ground or to a n o t h e rw i r e .I n s i m p l ee l e c t r o n i c st h, i s u s u a l l ym e a n s somethingwon't work at all.

How to Removethe ECMfor Testing
You can resetthe ECM in eitherof two ways:
NOTE: ' Make sure you have the anti theft code for the radio, then write down the frequenciesfor the radio's preset buttonsbeforeyou disconnectthe negativecable from the battery. . Enterthe anti theft code,then enter the customer's radio stationpresets,and set the clock after you reconnectthe negativecableto the battery.
NOTE:after resettingthe ECM,do the ECM idle learn p r o c e d u r e( s e ep a g e1 1 ' 1 0 0 ) .

Fueland EmissionsSystems System Descriptions ElestronicControl System The functionsof the fuel and emissionscontrol systemsare managedby the enginecontrol module (ECM). Fail-safe Function When an abnormalityoccursin the signalfrom a sensor,the ECM ignoresthe signaland assumesa pre-programmed value for the sensorthat allows the enqineto continueto run. Back-up Function When an abnormalityoccursin the ECM,the injectorsare controlledby a back-upcircuit independentofthe systemto p e r m i tm i n i m a ld r i v i n g . Self-diagnosis When an abnormalityoccursin the signalfrom a sensor,the ECMsuppliesground for the MIL and storesthe DTCin erasablememory. When the ignition is first turned ON (ll),the ECMsuppliesground for the MIL for 2 secondsto check t h e M I L b u l bc o n d i t i o n . Two Driving Cycle Detection Method To preventfalse indications,the "two driving cycle detectionmethod" is used for some self-diagnostic functions. When an abnormalityoccurs,the ECM storesit in its memory. When the same abnormalityrecursafter the ignition switch is turned OFFand ON (ll) again,the ECMturns on the l\411.

When the engine is cold and first started,the air pump pumps fresh air into the exhaustporls.The amount of air enteringthe exhaustis regulatedby an air control valve which is controlledby the ECM.The system does not work for more than 60 secondsat a time. Actual operatingtime will very dependingon the differencebetweenenginecoolant temDeratureand intakeair temDerature. When fresh air reactswith any unburnedexhaustgases,the exhaustgas temperaturesrise.This rise in temperature promotesfasterwarm-up of the catalyticconverter.resultingin cleaneremissionsdu ring cold stan-up. When the air inductionsystem is not operating,the air control solenoidclosesthe air control valve to preventany exhaustgasesfrom flowing back into the sytem.

Precautionsfor TorsenType LimitedSlip Differential(LSD)
TorsenType LimitedSlip Differential(LSDIOperationalCheck
. The Torsendifferentialsare mechanicallimited slip differentialswhich deliverthe availableDowerto the wheels and axleswith the most grip or resistanceas the enginetorque output increases. . Avoid repair proceduresthat requirethe engine runningwith one rearwheel raised;such as an oncar-wheelbalancer. . Do not tow the vehiclewith the rearwheels on the g rouno. . Neverdismantleany part ofthe differentialother than right and left taperedroller bearings. . To optimizethe Torsendifferentials,equip your vehiclewith reartires of the same brand.the same size,and with even wear.
The Torsentype limited slip differential(LSD) distributesoptimum power betweenthe two driving axlesaccordingto the differencein torque demanded by the driving wheels. U nder no circumstancesshould the engine be startedwith eitherwheel raisedoff the ground,such as using an on-car-wheelbalanceror when transportingthe vehiclein the event of accident. 1. Set the parkingbrake,and blockthe rearwheels. 2. Raisethe rear ofthe vehicle,and make sure it is securelysupported. 3. With the engine off. shift the transmissioninto 1st gear,and releasethe parkingbrake. 4. Rotateeither rearwheel by hand,and checkthat the other wheel rotatesin the oDDositedirection. Checkboth wheels. 5. lf the oppositerear wheel does not rotate,or if you c a n n o ts p i nt h e r e a rw h e e l sa t a l l ,t h e l i m i t e ds l i p differentialis faulty and should be replaced.

The Torsentype LSDassemblyconsistsof the two side gears,eight planetarygears,three side washers,tvvocenter washers,a gear casecover and a gear case. . The planetarygear consistsof the short and long planetarygears,and the long planetarygear mesheshorizontally with the side gear.The two planetarygears mesh with the side gearsat both ends. . The planetarygearsare housedin the pocketsof the gear case. . The left and right output shaftsare engagedwith the side gears .

When this takes place,the short and long pinion gears rotate,and walk aroundthe side gears in the directions shown lf, for example,the right shaft is rotatedin a counterclockwised irectionwith the differentjal carrierhetd stationary,the force is transmittedthrough the right side gear, short pinion gearsand long pinion gearsto the left side gear,causingthe left shaftto rotate in a clockwisedirection.This allows the outerwheel to tua ao.".,."a t h a nt h e i n n e rw h e e lw h e n t h e v e h i c l eg o e sa r o u n da t u r n .

When limiting differentialaction The limited slip differentialactsto limit the differentialactionwhen eitherwheel slips on ice or snow or on rurns. This is done by usingthe frictioncreatedbetweeneach gear and differentialcarrier: (1)The pinionsare forcedagainstthe differentialcarrier by the force as they are rotatedand repelledoutward. (2)The ends of the pinion gearsare held firmly againstthe differentialcarrier due to the side thrust from the h e l i c a l l yc u t g e a r s . l2l PINIORGEARS
