Component Function Check

INFOID:0000000012200072

1.

CHECK MAGNET CLUTCH OPERATION

Perform auto active test of IPDM E/R. Refer to 

PCS-12, "Diagnosis Description"

Does it operate normally?

YES

>> INSPECTION END

NO

>> Refer to 

HAC-85, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000012200073

1.

CHECK FUSE

1. Turn ignition switch OFF.

2. Check 10A fuse (No. 49, located in IPDM E/R). 

NOTE:

Refer to 

PG-82, "Fuse, Connector and Terminal Arrangement"

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the blown fuse after repairing the affected circuit if a fuse is blown. 

2.

CHECK MAGNET CLUTCH

1. Disconnect compressor connector. 

2. Directly apply battery voltage to the magnet clutch. Check for operation visually and by sound. 
Does it operate normally?

YES

>> GO TO 3.

NO

>> Replace magnet clutch. Refer to 

HA-30, "MAGNET CLUTCH : Removal and Installation of Com-

pressor Clutch"

.

3.

CHECK MAGNET CLUTCH POWER SUPPLY CIRCUIT FOR OPEN

1. Disconnect IPDM E/R connector.

2. Check continuity between IPDM E/R harness connector and compressor harness connector. 

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-37, "Removal and Installation"

.
