COMPRESSOR AND MAGNETIC
CLUTCH (1CD–FTV)
ON–VEHICLE INSPECTION
1. MAKE THESE VISUAL CHECKS:
(a) Leakage of grease from the clutch bearing
(b) Signs of oil on the pressure plate or rotor
2. INSPECT MAGNETIC CLUTCH BEARING FOR NOISE
(a) Start the engine.
(b) Check for abnormal noise from the compressor when the
A/C switch is OFF.
If abnormal noise is being emitted, replace the magnetic clutch.
3. INSPECT MAGNETIC CLUTCH OPERATION
(a) Disconnect the connector.
(b) Connect the positive (+) lead from the battery to the termi-
nal 3 on the magnetic clutch connector 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.
4. INSPECT COMPRESSOR LOCK SENSOR RESIS-
TANCE
(a) Disconnect the connector.
(b) Measure resistance between terminals 1 and 2.
Standard resistance: 65 – 125 Ω at 20C (68F)

ON–VEHICLE INSPECTION
1. INSPECT CONDENSER FAN OPERATION
Inspect the fan operation, as shown in the chart below.
Test conditions:

Ignition switch ON

Blower speed control dial at ”HI” position

Temperature control dial at ”COOL” position

Set on manifold gauge set

A/C switch ON
ConditionFan operation (Fan speed)
