Dye InjectionEJS006D3
(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 (3.45 bar, 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 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
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.
Electronic Refrigerant Leak DetectorEJS006D4
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.
2. When testing, circle each fitting completely with probe.

3. Move probe along component approximately 25 to 50 mm (1 to
2 in)/sec.
CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set (SST) to the A/C service valves.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm
2,50psi)above16°C. If
less than specification, recover/evacuate and recharge the system with the specified amount of refriger-
ant.
NOTE:
At temperatures below 16°C, leaks may not be detected since the system may not reach 345 kPa (3.45
bar, 3.52 kg/cm
2,50psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet g) to the
low-pressure side (evaporator drain hose h to shaft seal l). Refer toATC-140, "
Components". Perform a
leak check for the following areas carefully. Clean the component to be checked and move the leak
detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low-pressure flexible hoses, relief valve and shaft seal.
Liquid tank
Check the refrigerant pressure sensor.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
7. Start engine.
8. Set the heater A/C control as follows;
a. A/C switch: ON
b. MODE control dial: VENT (Ventilation)
c. Intake door position: Recirculation
d. Max. cold temperature
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.

10. Turn engine off and perform leak check again following steps 4 through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high-pressure side will gradually drop after
refrigerant circulation stops and pressure on the low-pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.
11. Discharge A/C system using approved refrigerant recovery equipment. Repair the leaking fitting or com-
ponent as necessary.
12. Evacuate and recharge A/C system and perform the leak test to confirm no refrigerant leaks.
13. Perform A/C performance test to ensure system works properly.

THE CURRENT POSITION MARK SHOWS A POSITION THAT IS COMPLETELY INCORRECT.
In the following cases, the current location mark may be displayed in a location that is completely incorrect. If
so, perform position/direction correction.
lWhen location correction has not been done
–If GPS satellite reception is poor and the current location mark slips out of place, it may shift to a com-
pletely unexpected location and not return unless location correction is performed. The position will be
corrected if a GPS signal can be received.
lWhen vehicle has traveled by ferry, or when vehicle has been towed.
VehicleUse of tire chains.
The vehicle mark may deviate from
the correct road.Drivethevehicleforawhile.Ifdis-
tance still deviates, adjust it with
the distance adjustment function. (If
tire chains are removed, recover
the original value.)
Use of tires other than the specified
sizeReplace all tires with the specified
size tire.
Malfunctioning air pressure of tireAdjust all tires to the specified air
pressure.
Replace tireDrive the vehicle for a while. If the
distance is still not in the correct
location, it adjusts with the distance
adjustment function.
Driving
mannerJust after the engine is startedIf vehicle is driven off just after the
engine is started when gyroscope
(angular speed sensor) correction is
not completed, the vehicle can can
be shown in the incorrect direction
and may deviate from the correct
location.Wait for a short while before driving
after starting the engine.
Continuous driving without stoppingWhen driving long distances without
stopping, direction errors may accu-
mulate, and the current location
mark may deviate from the correct
road.Stop and adjust orientation.
Abusive drivingSpinning the wheels or engaging in
other kinds of abusive driving may
result in the system being unable
perform correct detection, and may
cause the vehicle mark to deviate
from the correct road.If after traveling about 10 km (6
MPH) the correct location has not
been restored, perform location
correction and, if necessary, direc-
tion correction.
Position cor-
rection
methodPosition correction accuracy
If accuracy of location settings is
poor, accuracy may be reduced
when correct road cannot be found,
particularly in places where there
are many roads.From the roads displayed on the
screen, input a position within an
accuracy of 1mm (0.04 in).
CAUTION:
When correcting, use the most
detailed map possible.
Direction when location is corrected
If accuracy of location settings dur-
ing correction is poor, accuracy may
be reduced afterwards.Perform direction correction. Cause (condition) Driving condition Remarks (correction, etc.)
