Refrigerant Leak Check
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
5. Refrigerant Leak Check
A: INSPECTION
1) At engine speed below 1500rpm, operate the A/
C system for approx. 10 minutes, and confirm that
the high-side pressure shows at least 690 kPa
(7.03 kg/cm2, 100 psi). Then stop the engine to
start the leak test.
2) Starting from the connection between high-pres-
sure pipe and evaporator, check the system for
leaks along the high-pressure side through the
compressor. The following items must be checked
thoroughly.
3) Check the joint and seam between pressure
switch (dual switch) and high-pressure pipe.
4) Check the connections between condenser and
pipes, and welded joints on the condenser.
The leak tester may detect the oil on the condenser
fins as a leak.
5) Check the joint between compressor and hoses.
6) Check the machined area of the compressor and
other joints on the compressor.
7) Check the compressor shaft seal at the area
near the center of compressor clutch pulley.
Some shaft seals show a slight amount of leakage,
about 3 g (0.1 oz) per year. This is not a problem.
8) Starting from the connection between low-pres-
sure pipe and evaporator, check the system for
leakage along the low-pressure side through the
compressor. The following items must be checked
thoroughly.
•Connection between 2 parts
•Connection between pipe and plate
•Connection between pipes
9) Visually check the rubber area of the flexible
hose for cracks.
Check the entire length of the flexible hose, espe-
cially the connection with the metal hose end.
CAUTION:
Carefully check the external surface of hoses
and tubes at approx. 25 mm (0.98 in) per sec-
ond.
10) Disconnect the drain hose from the heater
case, and check the hose end for at least 10 sec-
onds.
After the test is finished, reconnect the drain hose.
11) Turn the ignition key to the ON position, and
run the blower at high speed for approx. 1 minute.
Stop the blower to check the ventilation grill on the
instrument panel. While moving the tester closer to
the grill, run the blower for 1 or 2 seconds, then stop
it. Check the grill at that point for at least 10 sec-
onds.
12) Check the valve in the service port.
13) Visually check the rubber seal in the service
port cap.

A: CAUTION
CAUTION:
•The airbag system wiring harnesses and con-
nectors are yellow. Do not use electrical test
equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness.
•While diagnostic items are being checked, do
not operate radios, portable telephones, etc.
which emit electromagnetic waves near or in-
side the vehicle.
•When turning the ignition switch to ON or
OFF while diagnostic items are being checked,
do not allow keys with different ID codes close
to the ignition switch. If the ignition key is in a
key holder, remove it from the holder before
carrying out diagnosis.
•When repeatedly turning the ignition switch
to ON or OFF while diagnostic items are being
checked, it should be switched in cycles of
“ON” for at least 5 seconds → “O F F ” fo r a t le a s t
8 seconds.
•If the engine fails to start with a registered ig-
nition key, detach the ignition key from ignition
switch and wait for approx. 1 second until secu-
rity indicator light begins to flash. And then
start the engine again.
•Before checking the diagnostic items, obtain
all keys for the vehicle to be checked pos-
sessed by owner.
•Do not install or register a body integrated
unit of another registered vehicle to diagnose
failures or inspect functions.
