Checking for Refrigerant LeaksNJS000FE
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electrical leak detector or fluorescent dye leak
detector (SST: J-42220).
If dye is observed, confirm the leak with an electrical leak detector. It is possible a prior leak was repaired and
not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electrical leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electrical leak detector probe slower and closer to the suspected leak area will improve the
chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorNJS000FF
1. Check A/C system for leaks using the UV lamp and safety goggles (SST: J-42220) in a low sunlight area (area without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a
bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (SST: J-43872) to prevent future misdiagnosis.
4. Perform a system performance check and verify the leak repair with an approved electrical leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.
Dye InjectionNJS000FG
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.52 kg/cm
2 , 50 psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (SST: J-41459).
3. Connect the injector tool to the A/C low-pressure side service valve.
4. Start the engine and switch A/C ON.
5. When the A/C operating (compressor running), inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye through the low-pressure service valve using dye injector tool (SST: J-41459) (refer to the manufacture’s
operating instructions).
6. With the engine still running, disconnect the injector tool from the service valve. CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system
connection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the leak size, operating conditions and location of the leak, it may take from minutes to days for the dye to
penetrate a leak and become visible.
8. Attach a blue label as necessary.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NFS000LN
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 for Procedures without Cowl Top CoverNFS000LO
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Brake SystemNFS000TE

Clean dust on front brake and rear brake with a vacuum dust collector. Do not blow with compressed air.

Recommended fluid is brake fluid “DOT 3”. MA-12, "Fluids and Lubricants" .

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas.

To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use new brake fluid.

Do not use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use a flare nut crowfoot and torque wrench when installing
brake tube.

When installing brake piping, be sure to check torque.

Before working, turn ignition switch OFF and disconnect con-
nectors for ABS actuator and electric unit (control unit) or battery
negative terminal.

Burnish the brake contact surfaces after refinishing or replacing
drums or rotors, after replacing pads or linings, or if a soft pedal
occurs at very low mileage.
Refer to BR-24, "
Brake Burnishing Procedure" (Front disc
brake), BR-30, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:

Clean brake pads and shoes with a waste cloth, then clean with a dust collector.

Precautions for Brake SystemNFS000MX

Recommended fluid is brake fluid “DOT 3”. Refer to MA-12, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .

Do not reuse drained brake fluid.

Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut crowfoot and torque wrench, securely tighten
brake tube flare nuts.

Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.

Before working, turn ignition switch OFF and disconnect electri-
cal connectors of ABS actuator and electric unit (control unit) or
battery negative terminal.

When installing brake piping, be sure to check torque.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlNFS000MY

During VDC/TCS/ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This
is normal.

Just after starting vehicle after turning ignition switch ON, brake pedal may vibrate or motor operating
noise may be heard from engine room. This is a normal status of operation check.

Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.

When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting
diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level, and
fluid leaks.

If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
