ELECTRICAL INCIDENT.GIMAEMLCECFECLMTATTFPDFARABRSTRSBTHAELIDXSupplemental Restraint System (SRS)AIR BAGThe SupplementalRestraint System AIR BAG, used along with a seat belt, helps to reduce the risk orseverity of injury to the driver and front passenger in a frontal collision. The Supplemental Restraint Systemconsists of air bag modules (located in the center of the steering wheel and in the instrument panel on thepassenger side), a diagnosis sensor unit, a crash zone sensor (4WD models), warning lamp, wiring harness,and spiral cable.The vehicle is equipped with a passenger air bag deactivation switch. Because no rear seat exists where arear-facing child restraint can be placed, the switch is designed to turn off the passenger air bag so that arear-facing child restraint can be used in the front passenger seat. The switch is located in the center of theinstrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag isenabled and could inflate in a frontal collision. When the switch is turned to the OFF position, the passengerair bag is disabled and will not inflate in a frontal collision. A passenger air bag OFF indicator on the instru-ment panel lights up when the passenger air bag is switched OFF. The driver air bag always remains enabledand is not affected by the passenger air bag deactivation switch.Information necessary to service the system safely is included in the RS section of this Service Manual.WARNING:GTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or deathin the event of a collision which would result in air bag inflation, all maintenance should be per-formed by an authorized NISSAN dealer.GImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-sonal injury caused by unintentional activation of the system.GDo not use electrical test equipment on any circuit related to the SRS unless instructed to in thisService Manual. SRS wiring harnesses are covered with yellow insulation either just before theharness connectors or on the complete harness, for easy identification.GThe vehicle is equipped with a passenger air bag deactivation switch which can be operated bythe customer. When the air bag is switched OFF, the passenger air bag is disabled and will notinflate in a frontal collision. When the passenger air bag is switched ON, the passenger air bag isenabled and could inflate in a frontal collision. After SRS maintenance or repair, make sure thepassenger air bag deactivation switch is in the same position (ON or OFF) as when the vehiclearrived for service.PrecautionsGBefore proceeding with disassembly, thoroughlyclean the outside of the transmission. It is impor-tant to prevent the internal parts from becomingcontaminated by dirt or other foreign matter.GDisassemblyshouldbedoneinacleanworkarea.GUselint-freeclothor towelsfor wipingpartsclean. Common shop rags can leave fibers thatcould interfere with the operation of the trans-mission.GPlace disassembled parts in order for easier andproper assembly.GAll parts should be carefully cleaned with a gen-eral purpose, non-flammable solvent beforeinspection or reassembly.GGaskets, seals and O-rings should be replacedanytime the transmission is disassembled.GThevalvebodycontainsprecisionpartsandrequires extreme care when parts are removedand serviced. Place removed parts in order, onapartsrack, sotheycanbeput backinthevalvebodyinthesamepositionsandsequences. Care will also prevent springs andsmall parts from becoming scattered or lost.GProperlyinstalledvalves, sleeves, plugs, etc.will slidealongtheir boresinthevalvebodyunder their own weight.GBefore assembly, apply a coat of recommendedATF to all parts. Apply petroleum jelly to protectO-rings and seals, or hold smallbearings andwashers in place during assembly. Do not usegrease.GExtreme care should be taken to avoid damageto O-rings, seals and gaskets when assembling.GIf A/T fluid contains frictional material (clutches,bands, etc.), replaceradiatorandflushcoolerline using cleaning solvent and compressed airafter repair of A/T. Refer to LC section(Radiator, ENGINE COOLING SYSTEM).GAfter overhaul, refillthe transmission with newATF.GWhen the A/T drain plug is removed, only someof the fluid is drained. Old A/T fluid will remainin torque converter and ATF cooling system.Always follow the procedures under ChangingA/T Fluid in the MA section when changing A/Tfluid.PRECAUTIONS AND PREPARATIONAT-2Service Notice or PrecautionsTORQUE CONVERTER SERVICEThe torque converter should be replaced under any of the following conditions:G External leaks in the hub weld area.G Converter hub is scored or damaged.G Converter pilot is broken, damaged or fits poorly into crankshaft.G Steel particles are found after flushing the cooler and cooler lines.G Pump is damaged or steel particles are found in the converter.G Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoseshave been made. (Converter clutch material may be glazed.)G Converter is contaminated with engine coolant containing antifreeze.G Internal failure of stator roller clutch.G Heavy clutch debris due to overheating (blue converter).G Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit areworn or damaged indicates that lining material came from converter.The torque converter should not be replaced if:G The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.G The threads in one or more of the converter bolt holes are damaged.G Transmission failure did not display evidence of damaged or worn internal parts, steel particles or clutchplate lining material in unit and inside the fluid filter.G Vehicle has been exposed to high mileage (only). The exception may be where the torque converter clutchdampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic, suchas taxi, delivery or police use.ATF COOLER SERVICEIf A/Tfluidcontainsfrictional material (clutches, bands, etc.), replaceradiatorandflushcoolerlineusingcleaning solvent and compressed air after repair of A/T.
