The BCM also sends a request, via the CAN communication lines, to the combination meter to flash the left
turn signal indicator. The unified meter control unit in the combination meter supplies ground to the left turn
signal indicator lamp and activates the audible turn signal indicator.
With power, ground and input supplied, the BCM controls the flashing of the turn signal lamps.
RH Turn Signal Lamp When turn signal switch is moved to the right turn position, the BCM receives an input signal requesting right
turn signals to flash. The BCM then supplies power

Inspection INFOID:0000000004784337
ENGINE OIL LEVEL NOTE:
Park vehicle on a level surface, wait 10 minutes and check the engine oil level.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within the range (A) shown.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE • Check engine oil for white milky or excessive contamination.
• If engine oil becomes white, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
ENGINE OIL LEAKAGE Check for engine oil leakage around the following areas:
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Intake valve timing control solenoid valve
• Front cover
• Mating surface between cylinder head and camshaft bracket
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seals (front and rear)
• Oil filter (for intake valve timing control)
OIL PRESSURE CHECK WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• For engine oil pressure check the transaxle should be in “ Park position” (A/T models) or “Neutral
position” (M/T models), and apply the parking brake securely.
1. Check engine oil level.
2. Disconnect harness connector at oil pressure switch (2), and remove oil pressure switch (2) from the cylinder block (1) using
suitable tool.
CAUTION:
Never drop or shock oil pressure switch. PBIC3817E

Engine Oil Pressure " .
If difference is extreme, check oil passage and oil pump for oil leaks.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification. Use Genuine Silicone RTV Sealant or equivalent. Refer to GI-42, " Recommended Chemical Product
and Sealant " .
c. Check engine oil level.
d. After warming up engine, make sure there are no leaks of engine oil with running engine.
Draining INFOID:0000000004784338
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause ski n cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible.
1. Warm up the engine, park vehicle on a level surface and check for engine oil leakage from engine compo- nents. Refer to LU-7, " Inspection " .
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove drain plug and then drain engine oil.
Refilling INFOID:0000000004784339
1. Install drain plug with new washer. Refer to EM-39, " Exploded View " .
CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil. Engine oil specification and viscosity: Refer to MA-14, " Fluids and Lubricants " .
CAUTION:
• The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
• Always use oil level gauge to determine the pr oper amount of engine oil in the engine.
3. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop engine and wait for 10 minutes.
5. Check the engine oil level. Refer to LU-7, " Inspection " .

SERVICE INFORMATION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004784384
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty 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 w hether 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 Man-
ual.
WARNING:
• To avoid rendering the SRS inoper ative, 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.
• Improper maintenance, including in correct removal and installation of the SRS can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000004673030
NOTE:
• This Procedure is applied only to models with Inte lligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecti ng 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 mech-
anism 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 pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE 1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.

6. Check oil pressure with engine running under no-load. Refer to LU-22, " Standard and Limit " .
If difference is extreme, check oi l passage and oil pump for oil leaks.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification. Use Genuine Silicone RT V Sealant or equivalent. Refer to GI-42, " Recommended Chemical Product
