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.

2. ELECTRONIC CONTROL SYSTEM
The electronic control system for controlling the shift timing and the operation of the lock±up clutch is
composed of the following 3 parts:
(a) Sensors: These sense the vehicle speed and throttle position and send this data to the ECM in the form
of electronic signals.
(b) ECM: This determines the shift and lock±up timing based upon the signals from the sensors.
(c) Actuators: Solenoid valves divert hydraulic pressure from one circuit of the hydraulic control unit to
another, thus controlling shifting and lock±up timing.
