Checkapplicablefuses in the appropriatefuse/relay oox. Some connectorshave a clip on their side used to attachthem to a mount bracketon the body or on a n o t h e rc o m p o n e n tT. h i sc l i p h a sa p u l lt y p e l o c k . Some mountedconnectorscannot be disconnected unlessyou first releasethe lock and removethe connectorfrom its mount bracket(A). 2. Checkthe batteryfor damage.stateof charge,and cleanand tight connections. . Do not quick-chargea batteryunlessthe battery ground cable has been disconnected,otherwise you will damagethe alternatordiodes. . Do not attemptto crankthe enginewith the batteryground cable looselyconnectedor you w i l l s e v e r e l yd a m a g et h e w i r i n g . Handling Connectors . Make surethe connectorsare clean and have no l o o s ew i r e t e r m i n a l s . . Make sure multiplecavity connectorsare packedwith dielectricgrease(exceptwatertight connectors). . All connectorshave push-downreleasetype locks(A). Nevertry to disconnectconnectorsby pulling on their wires; pull on the connectorhalvesinstead. Alwavs reinstallDlasticcovers, Beforeconnectingconnectors,make sure the terminals(A) are in placeand not bent. (cont'd) 22-3 BodyElectrical GeneralTroubleshootingInformation(cont'd) Checkfor looseretainer(A)andrubberseals(B). The backsof some connectorsare packedwith dielectricgrease.Add greaseif necessary.lf the greaseis contaminated,replaceit. HandlingWires and Harnesses . Securewires and wire harnessesto lhe frame with their respectivewire ties at the designatedlocations. . Removeclips carefully;don't damagetheir locks(A).

J lnsertthe connectorall the way and make sure it is securelvlocked. Positionwires so that the open end of the cover faces oown. After installingharnessclips, make sure the harness doesn't interferewith any moving pans. Keepwire harnessesaway from exhaustpipes and other hot parts,from sharp edgesof bracketsand holes,and from exposedscrewsand bolts. Seatgrommets in their grooves properly{A).

Verify The Complaint T u r n o n a l l t h e c o m p o n e n t si n t h e p r o b l e mc i r c u i t to verify the customercomplaint.Note the symptoms.Do not begin disassemblyor testing until you have narroweddown the problem area. 2. AnalyzeThe Schematic Look up the schematicfor the problem circuit. Determinehow the circuit is supposedto work by tracingthe currentpathsfrom the power feed through the circuitcomponentsto ground. lf severalcircuitsfail at the same time, the fuse or g r o u n di s a I i k e l yc a u s e . Basedon the symptoms and your understandingof the circuitoperation,identifyone or more possible causesof the problem. 3. lsolateThe ProblemBy TestingThe Circuit Make circuitteststo checkthe diagnosisyou made i n s t e p2 . K e e pi n m i n d t h a t a l o g i c a ls, i m p l e procedureis the key to efficienttroubleshooting. Testfor the most likelycauseof failure first, Try to make tests at pointsthat are easilyaccessible. 4. Fix The Problem Oncethe specificproblem is identified.make the repair.Be sure to use propertools and safe proceoures. 5. Make Sure The CircuitWorks Turn on all componentsin the repairedcircuit in all modes to make sure you've fixed the entire problem.lf the problemwas a blown fuse, be sure to test all of the circuitson the fuse. Make sure no n e w p r o b l e m st u r n u p a n d t h e o r i g i n a p l roblem does not recur. 22-6 Wire Color Codes The following abbreviationsare usedto identifywire colors in the circuitschematics: w H T . . . . . . . . . . . . . . . . . . . . , . , .

There are exclusivecommunicalionlines between the ECM,the gauge assembly,and the under,dash fuse/relaybox. Wake-upand Sleep The multiplexcontrol system has "wake-up" and "sleep" functions to decreaseparasiticdraw on the batterywhen the ignitionswitch is OFF. . ln the sleep mode,the multiplexcontrol unit stops functioning(communicationand CPUcontrol)when it is not necessaryfor the systemto operate. . As soon as any operationis requested(for example,a door is unlocked),the relatedcontrol unit in the sleep mode immediatelywakes up and beginsto function. . When the ignition switch is turned OFF,and the driver'sor front passenger'sdoor is opened,then closed,there is about a 10 seconddelay beforethe control unit goes from the wake-upmode to the sleep mode. . lf any door is open,the sleep mode will not function. . l f a k e y i s i n t h e i g n i t i o ns w i t c h ,t h e s l e e pm o d ew i l l not function. .
