Refrigerant Recovery Procedure
HVAC SYSTEM (HEATER, VENTILATOR AND A/C)
3. Refrigerant Recovery Proce-
dure
A: PROCEDURE
CAUTION:
•During operation, be sure to wear protective
goggles and protective gloves.
•Connect the refrigerant recovery system with
the manifold gauge set to discharge the refrig-
erant from the A/C system and recycle the gas.
•When recycling the discharged refrigerant,
keep service cans on hand. Because the recov-
ery rate with the recovery system is approx.
90%, service cans are necessary to charge the
refrigerant.
•Follow the detailed operation procedure de-
scribed in the operation manual attached to the
refrigerant recovery system.
1) Perform the compressor oil return operation.
2) Stop the engine.
3) Make sure the valves on low-/high-pressure
sides of manifold gauge set are fully closed.
4) Install the low-/high-pressure hoses to the ser-
vice ports on the low-/high-pressure sides of the
vehicle respectively.
5) Connect the center hose to the refrigerant recov-
ery system.
6) Follow the operation manual to activate the re-
frigerant recovery system.

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.

General Description
LAN SYSTEM (DIAGNOSTICS)
3. General Description
A: CAUTION
1. SRS AIRBAG SYSTEM
Airbag system wiring harness is routed near the
body integrated unit and twisted pair line.
CAUTION:
•All airbag system wiring harness and con-
nectors are colored yellow. Do not use the elec-
trical test equipment on these circuits.
•Be careful not to damage the airbag system
wiring harness when servicing the body inte-
grated unit and LAN system.
•Refer to “Airbag System” when disconnect-
ing the air bag system connector.
2. LAN SYSTEM
•Bus line of LAN system is twisted pair line. Be
careful not to bypass or partly unbind the twisted
pair line.
•Do not make clearance between bus lines (CAN
High, CAN Low).
•Difference of bus line length should be within 10
cm (3.94 in).
•Fray near the connector should be within 8 cm
(3.14 in).
•If the characteristics of the twisted pair line are
changed, it may extremely weaken against noise.
•When repairing the harness, connect the wires
using soldering and protect it with insulating tape
etc.
B: INSPECTION
Before performing diagnostics, check the following
item which might affect body integrated unit mal-
functions.
1) Measure the battery voltage and check electro-
lyte.
Standard voltage: 12 V or more
Specific gravity: Above 1.260
2) Check the fuse condition.
Make sure that ampere of the fuse is setting value,
and it is not blown out.
3) Check the connecting condition of harness and
harness connector.
4) Confirm settings of body integrated unit are cor-
responded to vehicle equipment.
UNIT (EQUIPMENT SETTING), OPERATION,

5) Confirm setting are corresponded to vehicle
equipment by function setting (ECM customizing)
of body integrated unit.

6) Confirm “Factory initial setting” of body integrat-
ed unit registrations is “Market”.
7) Confirm key illumination does not blink with igni-
tion switch turned to ON.
