CAUTION:
Moving the electronic 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 DetectorEJS000VK
1. Check A/C system for leaks using the UV lamp and safety glasses (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 opening indi-
cates an evaporator core assembly (tubes, core or TXV) 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 (J-43872) to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
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 InjectionEJS000VL
(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 (50 psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (J-41459).
3. Connect the injector tool to the A/C LOW PRESSURE side service fitting.
4. Start 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 J-41459 (refer to the manufacture's operat-
ing instructions).
6. With the engine still running, disconnect the injector tool from the service fitting.
CAUTION:
Be careful the A/C system or replacing a component, pour the dye directly into the open system con-
nection 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.
Electronic Refrigerant Leak DetectorEJS000VM
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C leak detector
or equivalent. Ensure that the instrument is calibrated and set prop-
erly 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.

3. Confirm secondary latch is securely engaged with secondary
striker by releasing it from a height of approximately 200 mm
(7.87 in) or by pressing it lightly approx.3kg (29 N).
NOTE:
Do not release hood from a height of 300 mm (11.81 in) or
higher.
4. Move hood lock up and down until striker smoothly engages the
lock when the hood is closed.
5. After adjustment, tighten lock mount bolts to the specified
torque.
Removal and Installation of Hood AssemblyEIS000KG
1. Disconnect washer hose at the connection.
2. Remove hinge mount nuts on the hood and then the hood assembly.

ABS FUNCTION
lDuring ABS operation, brake pedal lightly vibrates and its mechanical noise may be heard. This is a nor-
mal condition.
lWhen starting engine, or just after starting vehicle, brake pedal may vibrate. Also motor operating noise
may be heard from engine compartment. This is a normal status of operation check.
lWhen vehicle drives on rough, gravel, or snowy (fresh deep snow) road, the following conditions occur.
Stopping distance may be longer than that of vehicles without ABS.
4WD FUNCTION
lElectronically controlled 4WD is controlled by the same control module as that for ABS (4WD/ABS control
unit). 4WD/ABS control unit controls both electronically-controlled 4WD and ABS, based on input signals
from several sensors.
lIf electrical system-related malfunction occurred in 4WD/ABS system, control unit illuminates the following
lamps: 4WD warning lamp and/or ABS warning lamp on meter control unit assembly. This notifies driver of
malfunction. At the same time, control unit indicates malfunctioning part detected by self-diagnosis with
flashing pattern of LED. Indication on electronic system diagnosis tester (CONSULT) corresponds to this
flashing pattern as shown below.
