(g) Push the 2WD/4HI switch and check that the 4WD indica-
tor light goes off after it is blinking.
(h) Check the A.D.D. actuator operation by sound.
(i) Disconnect the actuator connector.
(j) Check the continuity between each terminal, as shown in
the chart.

5. REMOVE A.D.D. ACTUATOR (See page SA±43)
6. INSPECT CLUTCH HUB AND CLUTCH SLEEVE
(a) Check the clutch hub and clutch sleeve for wear and dam-
age.
If necessary, replace them.
(b) Check that clutch sleeve slides smoothly on the clutch
hub.
7. MEASURE SLEEVE FORK AND CLUTCH SLEEVE
CLEARANCE
Using a feeler gauge, measure the clearance between the
sleeve fork and clutch sleeve.
Maximum clearance: 0.35 mm (0.0138 in.)
If the clearance exceeds the maximum, replace the fork or
sleeve.

3. INSPECT IDLE±UP SPEED
(a) Warm up the engine.
(b) Inspect idle±up speed when the following conditions are
established.

Warm up engine

Blower speed control switch at ºHIº position

A/C switch ON

Temperature control dial at ºCOOLº position
Magnetic clutch conditionIdle±up speed
Magnetic clutch not engaged700 ± 50 rpm
Magnetic clutch engaged780 ± 50 rpm
If idle speed is not as specified, check the Idle control system.
4. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Perform under the following conditions:

Stop the engine.

Secure good ventilation (If not, the gas leak detec-
tor may react to volatile gases witch are not refriger-
ant, such as evaporated gasoline and exhaust gas.)

Repeat the test 2 or 3 times.

Make sure that there is some refrigerant remaining
in the refrigeration system.
When the compressor is OFF: approx. 392 to 588
kPa (4 to 6 kgf/ cm
2, 57 to 85 psi)
(b) Bring the gas leak detector close to the drain hose before
performing the test.
HINT:

After the blower motor stopped, leave the cooling unit for
more than 15 minutes.

Bring the gas leak detector sensor under the drain hose.

When bringing the gas leak detector close to the drain
hose, make sure that the gas leak detector does not react
to the volatile gases.
If such reaction is unavoidable, the vehicle must be lifted up.
(c) If gas leak is not detected on the drain hose, remove the
blower motor linear controller from the cooling unit. Then
insert the gas leak detector sensor into the unit and per-
form the test.
(d) Disconnect the connector and leave the pressure switch
for approx. 20 minutes. Then bring the gas leak detector
close to the pressure switch and perform the test.
(e) Bring the gas leak detector close to the refrigerant lines
and perform the test.

2. START ENGINE
3. INSPECT COMPRESSOR FOR METALLIC SOUND
Check if a metallic sound can be heard from the compressor
when the A/C switch is on.
If a metallic sound cannot be heard, replace the compressor as-
sembly.
4. INSPECT REFRIGERANT PRESSURE
(See page AC±3)
5. STOP ENGINE
6. INSPECT VISUALLY FOR LEAKAGE OF REFRIGER-
ANT FROM SAFETY SEAL
Using a gas leak detector, check for leakage of refrigerant.
If there is any leakage, replace the compressor assembly.
7. REMOVE MANIFOLD GAUGE SET
(See page AC±19)
8. CHECK FOR LEAKAGE OF GREASE FROM CLUTCH
BEARING
9. CHECK FOR SIGNS OF OIL ON PRESSURE PLATE
If necessary, repair or replace.
10. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start the engine.
(b) Check if abnormal noise is heard from near the compres-
sor when the A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
11. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
3 and the negative (±) lead to body ground.
(c) Check that the magnetic clutch is energized.
If operation is not as specified, replace the magnetic clutch.
12. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure the resistance between terminals 1 and 2.
Standard resistance:
165 to 205 W at 20°C (68°F)
If resistance is not as specified, replace the compressor.
