Diagnosis Procedure

INFOID:0000000010500542

1.

CHECK MAGNET CLUTCH

CONSULT

1.

Turn ignition switch OFF

2.

Disconnect compressor connector. 

3.

Select “COMPRESSOR” of IPDM E/R active test item.

4.

With operating the test item, check Check voltage between compressor harness connector and ground.

Does it operate normally?

YES

>> GO TO 4.

NO

>> GO TO 2.

2.

CHECK FUSE

1.

Turn ignition switch OFF

2.

Check 15 A fuse (No. 57, located in IPDM E/R).
NOTE:
Refer to 

PG-109, "Fuse, Connector and Terminal Arrangement"

. 

Is the inspection result normal?

YES

>> GO TO 3.

NO

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

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-68, "Removal and Installation"

.

NO

>> Repair harness or connector. 

4.

CHECK MAGNET CLUTCH GROUND CIRCUIT FOR OPEN

Check continuity between compressor harness connector and ground.
