 When recharging refrigerant, check for leaks.
Checking of Refrigerant LeaksINFOID:0000000001328231
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 ma y 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, c onfirm 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 electric al 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 Fluore scent Leak DetectorINFOID:0000000001328232
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 co mponents, 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. Low-pressure pipe 1 bracket mounting bolt

4. Perform a system performance check and verify the l eak 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 InjectionINFOID:0000000001328233
(This procedure is only necessary when recharging t he 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 refr igerant 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 inje ctor 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 componen t, pour the dye directly into the open system
connection and proceed wi th 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.
Electrical Leak DetectorINFOID:0000000001328234
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C electrical leak
detector (SST) or equivalent. Ensure that the instrument is calibrated
and set properly per the operating instructions.
The leak detector is a delicate device. In order to use the leak detec-
tor properly, read the operating instructions and perform any speci-
fied maintenance.
1. Position probe approximately 5 mm (3/16 in) away from point to
be checked.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612918
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 “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipmen t 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.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001612920
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for Brake SystemINFOID:0000000001327604
 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-9, "
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 connec- tors for ABS actuator and electric unit (control unit) or battery neg-
ative 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-23, "
Brake Burnishing Procedure" (Front disc brake),
BR-29, "
Brake Burnishing Procedure" (Rear disc brake).
WARNING:
 Clean brake pads and shoes with a waste cl oth, then clean with a dust collector.
