PEDAL STROKE

When parking brake pedal is operated with a force of 196 N (20.0 kg, 44.1 lb), make sure parking brake
pedal stroke is within the specified number of notches. (Check it by listening and counting the ratchet
clicks.)

Make sure that brake warning lamp comes on when parking brake pedal is depressed with in one notch.
INSPECT COMPONENTS

Make sure the components are installed properly (check for looseness, backlash, etc.).

Check parking brake pedal assembly for bend, damage and cracks, and replace if necessary.

Check cable for wear and damage, and replace if necessary.

Check parking brake warning lamp switch for malfunction, and replace if necessary.
ADJUSTMENT
1. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, return pedal.
2. Remove tyres from vehicle.
3. Using wheel nuts, fix disc rotor to hub and prevent it from tilting.
4. Remove adjusting hole plug installed on disc rotor. Using a flat-
bladed screwdriver, turn adjuster to clockwise in the figure until
disc rotor is locked. After locking, turn adjuster to opposite direc-
tion by 5 or 6 notches.
5. Rotate disc rotor to make sure that there is no drag. Then install
adjusting hole plug.
6. After adjusting the clearance of rear shoes, with no drag on rear
brake, adjuster cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg,
11 0 l b ) .
b. Depress pedal until a deep socket wrench can be inserted.
Insert deep socket, and rotate adjusting nut to adjust pedal stroke.
CAUTION:
Do not reuse adjusting nut after removing it.
c. When parking brake pedal is operated with a force of 196 N (20.0 kg, 44.1 lb), make sure the stroke is
within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
d. With parking brake pedal completely returned, make sure there is no drag on rear brake.Pedal stroke : 3 − 4 notches

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BGS0004B
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 DisconnectBGS0004C
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-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 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 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

Precautions for Steering SystemBGS0003L

In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.

Observe the following precautions when disassembling.
–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.
–Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.

POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelBGS0003P

Check fluid level with the engine stopped.

Make sure that fluid level is between MIN and MAX.

Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:

The fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.

Do not reuse drained power steering fluid.
Checking Fluid LeakageBGS0003Q
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80°C
(122 to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
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
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-29, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid, indicating from steering gear.
Air Bleeding Hydraulic SystemBGS0003R
If air bleeding is not complete, the following symptoms can be observed.

Bubbles are created in reservoir tank.

Clicking noise can be heard from oil pump.

Excessive buzzing in oil pump.
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of
the system.
1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Filling reservoir tank with fluid so as not to lower fluid level below the MIN line while steering
wheel turning.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and white contamination.
5. Stop engine if bubbles and white contamination do not drain out. Perform steps 2 to 3 above after waiting
until bubbles and white contamination drain out.HOT : Fluid temperature 50 – 80°C (122 – 176°F)
COLD : Fluid temperature 0 – 30°C (32 – 86°F)
