PRECAUTIONS PRECAUTIONS PFP:00001 Precautions for Supplemental Restraint System (SRS) AIR BAG and SEAT BELT PRE-TENSIONER
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 for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS 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 are belted or unbelted. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual. WARNING: G To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. G Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section. G Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

EGS0010H
Before disassembly, thoroughly clean the outside of the unit. Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter. For easier and proper assembly, place disassembled parts in order on a parts rack. Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might interfere with their operation. Before inspection or reassembly, carefully clean all parts with a general purpose, non-flammable solvent. Before assembly, apply a coat of recommended Genuine NISSAN PSF or equivalent to hydraulic parts. Petroleum jelly may be applied to O-rings and seals. Do not use any grease. Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during installation. Perform functional tests whenever designated.

Check the lines for improper attachment and for leaks, cracks, damage, loose connections, chafing and deterioration. 1. Run engine between idle speed and 1,000 rpm. Make sure temperature of fluid in oil tank rises to 60 80C (140 176F). 2. Turn steering wheel right-to-left several times. 3. Hold steering wheel at each lock position for five seconds and carefully check for fluid leakage. CAUTION: Do not hold the steering wheel in a locked position for more SGIA0506E than 15 seconds. 4. If fluid leakage at connectors is noticed, loosen flare nut and then retighten. Do not overtighten connector as this can damage O-ring, washer and connector. 5. If fluid leakage from power steering oil pump is noticed, check the power steering oil pump. Refer to PS21, "On-Vehicle Service" . 6. Check steering gear boots for accumulation of power steering fluid, indicating a steering gear leak.

Start the engine then repeat step 2 above. Incomplete air bleeding will cause the following symptoms: G Air bubbles in reservoir tank G Clicking noise in oil pump G Excessive buzzing in oil pump If this happens, bleed out the air repeating step 2 above. Fluid noise may occur in the valve or oil pump. This is common when the vehicle is stationary or while turning the steering wheel slowly. This does not affect the performance or durability of the system.
