NOTE:
A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to
perform operation while checking data with CONSULT-II.
a. Connect CONSULT-II to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Read out the value of “ATF TEMP 1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65 °C (149 °F) using “HOT” range on A/
T fluid level gauge.
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

To check A/T fluid level, insert the A/T fluid level gauge
until the cap contacts the end of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.

If ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-14,
"RADIATOR" (for VQ35DE) or CO-41, "RADIATOR" (for
VK45DE) and AT- 1 5 , "
A/T Fluid Cooler Cleaning" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
10. Tighten level gauge bolt.
Level gauge bolt: : 5.1 N·m (0.52 kg-m, 45 in-lb)

Checking Seat Belt, Buckles, Retractors, Anchors and AdjustersALS000YT
CAUTION:

After any collision, inspect all seat belt assemblies, including retractors and other attached hard-
wares (I.e. anchor bolt, guide rail set). Nissan recommends to replace all seat belt assemblies in
use during a collision, unless not damaged and properly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision, and replace if damaged or improp-
erly operating.
Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal col-
lision where the driver and passenger air bags are deployed.

If any component of seat belt assembly is questionable, do not repair.
Replace as seat belt assembly.

If webbing is cut, frayed, or damaged, replace belt assembly.

Never oil tongue and buckle.

Use a genuine NISSAN seat belt assembly.
For details, refer to Refer to Service Manual in SB section.

Check anchors for loose mounting

Check belts for damage

Check retractor for smooth operation

Check function of buckles and tongues when buckled and released

INSPECTION AFTER REMOVAL
Lining Thickness Inspection

Check thickness of lining.
Drum Inner Diameter Inspection

Check drum inner diameter.
Other Inspections

Check shoe sliding surface for excessive wear and damage.

Check anti-rattle pin for excessive wear and corrosion.

Check return spring for sagging.

Check adjustor for rough operation.

Check either visually or with a vernier caliper to see if there is
any excessive wear, cracks, or damage inside drum.
INSTALLATION
Be careful of the following:

Refer to “Component Parts Location” and apply brake grease to the specified points during assembly.

Assemble adjuster so that threaded part expands when rotating
it in the direction shown by the arrow.

Shorten adjuster by rotating it.

When disassembling adjuster, apply PBC (Poly Butyl Cuprysil)
grease or silicone based grease to the threads.

After replacing brake shoes or disc rotors, or if brakes do not
function well, perform break-in operation as follows.
1. Adjust parking brake pedal stroke to the specified stroke.
2. Perform parking brake break-in (drag run) operation by driving the vehicle under the following conditions:
3. After break-in operation, check lever stroke of parking brake. Readjust if it is no longer at the specified stroke.

To prevent lining from getting too hot, allow a cool off period of approximately 5 minutes after every
break-in operation.

Do not perform excessive break-in operations, because it may cause uneven or early wear of lining. Standard thickness (A) : 3.2 mm (0.126 in)

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AGS000GO
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 Man-
ual.
WARNING:

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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

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.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectAGS000L5
NOTE:

This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).

Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″ LOCK ″ position.

Always use CONSULT-II 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 NVIS/IVIS, 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.
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 all control units using CONSULT-II.
Precautions for Steering SystemAGS000GP

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 becom-
ing contaminated by dirt or other foreign matter.

For easier and proper assembly, place disassembled parts in order on a parts rack.
