Manual Description
FUEL LEVEL SENSOR UNIT, FUEL FILTER, (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" 2, precaution Necessary for Steering Wheel Rotation After Battery Disconnect 2, precaution for Supplemental Restraint System (SRS) "AIR BAG" "SEAT BELT.
The Supplemental Restraint System such as AIR BAG” and SEAT BELT PRE-TENSIONER”, used along, with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger certain, system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front, air bag, depending on the severity of a collision and whether the front occupants belted unbelted.
Information necessary to service the system safely is included in the SRS and SB section Service Manual, to avoid rendering the SRS inoperative, which could increase the risk of personal injury death, the event of a collision which would result in air bag inflation, all maintenance must be performed by, improper maintenance, including incorrect removal and installation of the SRS can lead personal.
Injury caused by unintentional activation of the system, pRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS, when working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near sensor(s) with, when using air or electric power tools or hammers, always switch the Ignition OFF, disconnect.
Battery, and wait at least 3 minutes before performing any service, precaution Necessary for Steering Wheel Rotation After Battery Disconnect, this Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYSTEM), remove and install all control units after disconnecting both battery cables with the ignition knob.
Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work, if DTC is detected, perform trouble diagnosis according self-diagnostic results, for models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mechanism is adopted key cylinder, for this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock.
Steering wheel rotation will become impossible, if steering wheel rotation is required when battery power is interrupted, follow procedure below before, supply power using jumper cables battery discharged, the actual shapes of the Kent-Moore tools may differ from those of the special tools illustrated here.
Removing and installing fuel tank lock ring, inspect fuel lines, fuel filler cap and fuel tank for improper attachment, leaks, cracks, damage, loose connections, chafing deterioration, if necessary, repair replace damaged parts, when replacing fuel line parts, be sure observe following.
Put a CAUTION: FLAMMABLE” sign work area, be sure to work in a well ventilated area and have CO2 fire extinguisher, do not smoke while working on the fuel system, put drained fuel in an explosion-proof container and put the lid on securely.
Use gasoline required by the regulations for octane number, (Unleaded Regular Gasoline Recommended) MR20DE and QR25DE Except SE-R Spec-V" GI-5, "Precaution for Fuel (Unleaded Premium Gasoline Required) QR25DE SE-R Spec-V Only", before removing fuel line parts, perform following procedures.
- Release fuel pressure from the fuel lines, "System Description" MR20DE (except California), or EC-1195, "Fuel Pressure Check", - Disconnect battery ground cable, always replace O-rings and clamps with new ones.
Do not tighten hose clamps excessively avoid damaging hoses, after connecting fuel tube quick connectors, make sure quick connectors secure, ensure that connector and resin tube do not contact any adjacent parts, after installing tubes, make sure there is no fuel leakage at connections following steps.
- Apply fuel pressure to fuel lines by turning ignition switch ON (without starting engine), check for fuel leaks at fuel tube connections, - Start engine and rev it up and check for fuel leaks connections, use only a genuine NISSAN fuel filler cap as a replacement.
For servicing Evaporative Emission System” parts, refer to EC-52, "System Description" MR20DE, (California), "Description" MR20DE (except California), EC-1138, "Description" QR25DE, for servicing "On Board Refueling Vapor Recovery (ORVR)" parts, refer to Refer EC-52, "System.
