INSPECTION
1. INSPECT COMPRESSOR AND MAGNETIC CLUTCH (A/C LOCK SENSOR)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
If the resistance is not as specified, replace the compressor and magnetic clutch.
2. INSPECT COMPRESSOR AND MAGNETIC CLUTCH (A/C COMPRESSOR SOLENOID)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
If the resistance is not as specified, replace the compressor and magnetic clutch.
3. INSPECT COMPRESSOR AND MAGNETIC CLUTCH
(a) Disconnect the connector from the compressor and magnetic clutch.
(b) Disconnect the connector from the magnetic clutch.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
If the resistance is not as specified, replace the compressor and magnetic clutch.
4. INSPECT MAGNETIC CLUTCH
(a) Measure the resistance according to the value(s) in the table below.
