ON±VEHICLE INSPECTION
1. INSPECT COMPRESSOR FOR METALLIC SOUND
(a) Start engine.
(b) Check if there is a metallic sound from the compressor
when the A/C switch is on.
If metallic sound is heard, replace the compressor assembly.
2. INSPECT REFRIGERANT PRESSURE
See ºON±VEHICLE INSPECTIONº of AIR CONDITIONING
SYSTEM on page AC±3.
3. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure resistance between terminals 1 and 2.
Standard resistance: 65 ± 125 W at 20 °C (68 °F)
If resistance is not as specified, replace the compressor assem-
bly.
4. 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.
5. CHECK FOR LEAKAGE OF GREASE FROM CLUTCH
BEARING
6. CHECK FOR SIGNS OF OIL ON PRESSURE PLATE OR
ROTOR
7. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start engine.
(b) Check for abnormal noise from near the compressor
when the A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
8. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to terminal
4 and the negative (±) lead to the body ground.
(c) Check that the magnetic clutch is energized.
If operation is not as specified, replace the magnetic clutch.

REASSEMBLY
Reassembly is in the reverse order of disassembly
(See page AC±43).
AFTER REASSEMBLY, CHECK MAGNETIC CLUTCH
CLEARANCE
(a) Set the dial indicator to the pressure plate of the magnetic
clutch.
(b) Connect the magnetic clutch lead wire to the positive (+)
terminal of the battery.
(c) Check the clearance between the pressure plate and ro-
tor when connecting the negative (±) terminal to the bat-
tery.
Standard clearance:
0.5 ± 0.15 mm (0.020 ± 0.0059 in.)
If the clearance is not within the standard clearance, adjust the
clearance using shims to obtain the standard clearance.
Shim thickness:
0.1 mm (0.004 in.)
0.3 mm (0.012 in.)
0.5 mm (0.020 in.)
