Precaution 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 AIRBAG article and SEAT BELTS article.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

Note. 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 in the "LOCK" position. 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 to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mechanism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation.

Scheme 21

1. Before starting the engine make sure the vehicle is parked on a flat and level surface, then check the oil level. If the engine is already running, turn it off and allow 10 minutes before checking.
2. Check that the oil level is within the low (L) to high (H) range as indicated on the dipstick.
3. If the engine oil level is out of range, add oil as necessary. Refer to " «FOR NORTH AMERICA : FLUIDS AND LUBRICANTS»(ref-382161-S12522039562011011400000) ".

OIL APPEARANCE

1. Check the engine oil for a white milky appearance or excessive contamination.
2. If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken parts.

OIL LEAKAGE

Check for oil leakage around the following areas

1. Oil pan
2. Oil pan drain plug
3. Oil pressure switch
4. Oil filter
5. Oil cooler
6. Intake valve timing control cover
7. Intake valve timing control solenoid valve
8. Front cover
9. Mating surface between cylinder block and cylinder head
10. Mating surface between cylinder head and rocker cover
11. Crankshaft oil seal (front and rear)

OIL PRESSURE CHECK

Scheme 22

Scheme 23

1. Check the engine oil level. Refer to " «INSPECTION»(ref-382188-S37522985312011011400000) ".
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure switch harness connector.
4. Remove the oil pressure switch (A).
5. Install Tools. Tool number : ST25051001 (J-25695-1) : ST25052000 (J-25695-2)
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load. Engine oil pressure [Engine oil temperature at 80°C (175°F)] ENGINE SPEED REFERENCE Unit: kPa (kg/cm 2 , psi) Engine Speed Approximate Discharge Oil Pressure Idle speed More than 98 (1.0, 14) 2,000 RPM More than 294 (3.0, 43) CAUTION: If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure switch as follows: Remove old liquid gasket adhering to oil pressure switch and engine. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Sealant or equivalent. Refer to " «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-382152-S15373783892011011400000) ". Oil pressure switch torque : 14.8 N.m (1.5 kg-m, 11 ft-lb) After warming up engine, make sure there is no leakage of engine oil with engine running.
