INSTALLATION
NOTICE:

Never use seat belt pretensioner from another ve-
hicle. When replacing parts, replace them with new
parts.

Make sure that the front seat outer belt is installed to
the specified torque.

If the front seat outer belt has been dropped, or there
are cracks, dents or other defects in the case or con-
nector, replace the front seat outer belt with a new
one.

When installing the front seat outer belt, take care that
the wiring does not interfere with other parts and is
not pinched between other parts.
1. Other front seat outer belts:
INSTALL RETRACTOR OF FRONT SEAT OUTER BELT
(a) Install the retractor of front seat outer belt with the 2 bolts.
Torque: 42 N´m (430 kgf´cm, 31 ft´lbf)
(b) Connect the pretensioner connector as shown in the il-
lustration.
2. INSTALL LOWER CENTER PILLAR GARNISH
(a) Install the lower center pillar garnish.
(b) Install the front seat outer belt floor anchor.
Torque: 42 N´m (430 kgf´cm, 31 ft´lbf)
3. INSTALL REAR DOOR OPENING TRIM WEATH-
ERSTRIP
4. INSTALL REAR DOOR SCUFF PLATE
5. INSTALL FRONT DOOR OPENING TRIM WEATH-
ERSTRIP
6. INSTALL FRONT DOOR SCUFF PLATE
7. CONNECT CABLE TO NEGATIVE BATTERY TERMI-
NAL
8. PERFORM INITIALIZATION (See page IN±20)
Some systems need initialization when disconnecting the cable
from the negative battery terminal.

ON±VEHICLE INSPECTION
1. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Remove the console box assembly.
(b) Remove the glove compartment door.
(c) Remove the lower No. 2 finish panel.
(d) Remove the heater to register duct No. 4.
(e) Remove the lower LH finish panel.
(f) Remove the lower cover (See page BO±89).
(g) Remove the blower controller.
(1) Disconnect the connector.
(2) Remove the 2 screws and blower motor linear con-
troller.
(h) Using a gas leak detector, check for leakage.
If there is leakage, check the tightening torque at the joints or
check the evaporator.
(i) Install the blower motor linear controller with the 2 screws.
(j) Install the lower cover.
(k) Install the lower LH finish panel.
(l) Install the lower No.2 finish panel.
(m) Install the glove compartment door (See page BO±97).
2. INSPECT EXPANSION VALVE
(a) Set the manifold gauge set.
(b) Run the engine.
(c) Check quantity of gas with the sight glass in refrigeration
cycle.
(1) Run the engine at 1,500 rpm for at least 5 minutes.
(2) Then check that the high pressure reading is 1.37
to 1.57 Mpa (14 to 16 kgm/cm
2, 199 to 228 psi).
(d) Check the expansion valve.
If the expansion valve is faulty, the low pressure reading will
drop to 0 kPa (0 kgf/cm
2, 0 psi).
HINT:
When the low pressure reading drops to 0 kPa (0 kgf/cm
2, 0
psi), there is no difference in temperature between the IN and
OUT sides of the receiver.
3. INSPECT THERMISTOR RESISTANCE
(a) Disconnect the connector.
(b) Measure the resistance between terminals.
Standard resistance: 1,500 W at 25°C (77°F)
If resistance is not as specified, replace the thermistor.
