INSPECTION

1. INSPECT A/C COMPRESSOR






(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:





If the resistance is not as specified, replace the A/C compressor.
2. INSPECT MAGNETIC CLUTCH





(a) Measure the resistance of the connector.
Standard resistance:





If the resistance is not as specified, replace the magnetic clutch.
(b) When connector terminal A1 is connected to the positive (+) battery terminal, check that the following occurs: 1) the magnetic clutch's operating sound can be heard, and 2) the magnetic clutch's hub and rotor lock.
