MAGNET CLUTCH


Diagnosis Procedure

1.CHECK CHARGED REFRIGERANT
Connect the recovery/recycling recharging equipment to the vehicle and perform the pressure inspection with the gauge. Refer to Performance Test.
Is there refrigerant?
YES - GO TO 2.
NO - Check for refrigerant leakages detecting fluorescent leak detector. Refer to Leak Test.
2.CHECK MAGNET CLUTCH OPERATION
Perform auto active test of IPDM E/R. Refer to 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 the compressor.
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:
Refer to IPDM E/R (Intelligent Power Distribution Module Engine Room)
Is the inspection result normal?
YES - Replace IPDM E/R.
NO - Replace the fuse after repairing the applicable circuit.
6.CHECK SELF-DIAGNOSIS RESULT CHECK
With CONSULT-III
1. Perform the "SELF-DIAGNOSIS".
2. Check if any DTC is detected in the self-diagnostic results.

NOTE:
If DTC is displayed along with DTC "U1000" or "U1010", first diagnose the DTC "U1000" or "U1010". Refer to With 7 Inch Display or With 7 Inch Display.
Is any DTC displayed?
YES - Perform the diagnosis that is applicable to the sensor and actuator. Refer to With 7 Inch Display.
NO - GO TO 7.
7.CHECK A/C AUTO AMP. OUTPUT SIGNAL
With CONSULT-III
1. Perform the "DATA MONITOR" of HVAC. Refer to Testing and Inspection.
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. Refer to Diagnosis Procedure.
Is the inspection result normal?
YES - INSPECTION END
NO - Repair or replace the malfunctioning parts.
