MAGNET CLUTCH

Description

INFOID:0000000009951004

• The magnet clutch is the device that drives the compressor with the signal from IPDM E/R. 
• Compressor is driven by the magnet clutch which is charged magnetic force by electrified.
• IPDM E/R controls magnet clutch by turning the built in A/C relay to ON 

⇔

 OFF according to ECM request.

Component Function Check

INFOID:0000000009951005

1.

CHECK MAGNET CLUTCH OPERATION

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

PCS-10, "Diagnosis Description"

 (WITH I-KEY) or 

PCS-41,

"Diagnosis Description"

 (WITHOUT I-KEY). 

Does it operate normally?

YES

>> INSPECTION END

NO

>> Go to diagnosis procedure. Refer to 

HAC-59, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009951006

1.

CHECK MAGNET CLUTCH

1.

Turn the ignition switch OFF.

2.

Disconnect the magnet clutch connector. 

3.

Directly apply the battery voltage to the magnet clutch. Check for operation visually and by sound. 

Does it operate normally?

YES

>> GO TO 2.

NO

>> Replace magnet clutch. Refer to 

HA-33, "MAGNET CLUTCH : Removal and Installation"

.

2.

CHECK MAGNET CLUTCH CIRCUIT CONTINUITY

1.

Turn the ignition switch OFF.

2.

Disconnect the IPDM E/R connector.

3.

Check continuity between magnet clutch harness connector and IPDM E/R harness connector. 

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the harnesses and connectors. 

3.

CHECK FUSE

Check 10A fuse (No. 49, located in the IPDM E/R). 
NOTE:
Refer to 

PG-79, "Fuse, Connector and Terminal Arrangement"

. 

Is the inspection result normal?

YES

>> Replace the IPDM E/R. 

NO

>> Replace the fuse after repairing the applicable circuit.

.

Diagnosis Procedure

INFOID:0000000009951008

1.

CHECK A/C SWITCH SIGNAL

1.

Turn the ignition switch ON.

2.

Check output waveform between A/C auto amp. harness connector and the ground with using oscillo-
scope.

Is inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the A/C auto amp.

2.

CHECK CONTINUITY BETWEEN A/C AUTO AMP. AND BCM

1.

Turn the ignition switch OFF.

2.

Disconnect the A/C auto amp. connector.

3.

Disconnect the BCM connector.

4.

Check continuity between A/C auto amp. harness connector and BCM harness connector.

Is inspection result normal?

YES

>> GO TO 3.

NO

>> Repair the harnesses or connectors.
