Description

The magnet clutch is the device that drives the compressor with the signal from IPDM E/R.


Component Function Check


1. CHECK OPERATION

1.Turn the fan control dial ON.
2.Press the A/C switch.
3.Check that the indicator of the A/C switch turns ON. Check visually and by sound that the compressor operates.
4.Press the A/C switch again.
5.Check that the indicator of the A/C switch turns OFF. Check visually and by sound that the compressor stops.
Does it operate normally?
YES- INSPECTION END
NO- Go to diagnosis procedure. .


Diagnosis Procedure


1. CHECK CHARGED REFRIGERANT

Connect the recovery/recycling recharging equipment to the vehicle and perform the pressure inspection with the gauge. Performance Test.
Is there refrigerant?
YES- GO TO 2.
NO- Check for refrigerant leakages detecting fluorescent leak detector. Leak Test.

2. CHECK MAGNET CLUTCH OPERATION

Perform auto active test of IPDM E/R. Diagnosis Description.
Does it operate normally?
YES- GO TO 6.
NO- GO TO 3.

3. 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 4.
NO- Replace magnet clutch. Service and Repair.

4. CHECK MAGNET CLUTCH CIRCUIT CONTINUITY

1.Turn the ignition switch OFF.
2.Disconnect IPDM E/R connector.
3.Check continuity between the magnet clutch harness connector and IPDM E/R harness connector.





4.Check for continuity between IPDM E/R harness connector and ground.





Is the inspection result normal?
YES- GO TO 5.
NO- Repair the harnesses and connectors.

5. CHECK FUSE

Check 10A fuse (No. 49, located in the IPDM E/R).
NOTE:
IPDM E/R.
Is the inspection result normal?

2.Check A/C ON signal and blower fan ON switch signal.





Is the inspection result normal?
YES- GO TO 8.
NO- Replace A/C auto amp.

8. CHECK REFRIGERANT PRESSURE SENSOR

Check the refrigerant pressure sensor. Refrigerant Pressure Sensor.
Is the inspection result normal?
YES- INSPECTION END
NO- Repair or replace the malfunctioning parts.
