MAGNET CLUTCH
DescriptionINFOID:0000000012430746
SYSTEM DESCRIPTION
When the blower speed dial is in one of the fan speed pos itions, the front air control outputs a fan ON signal to
the BCM. When the A/C switch is pressed, the A/C switch LED illuminat es and the front air control outputs a
compressor ON signal to the BCM. Any mode control button can be selected. As long as the BCM receives a
compressor ON signal and a fan ON signal from the front air control, the conditions required for the BCM to
transmit a compressor ON request to the ECM have been met.
The BCM sends a compressor ON signal to ECM, via CAN communication line.
The ECM judges whether the compressor can be turned ON, based on each sensor status (refrigerant pres-
sure sensor signal, throttle angle sensor, etc.). If it judges the compressor can be turned ON, it sends a com-
pressor ON signal to IPDM E/R, via CAN communication line.
Upon receipt of a compressor ON signal from ECM, IPDM E/R turns the A/C relay ON to operate the compres-
sor.
Component Function CheckINFOID:0000000012430747
1.CHECK MAGNET CLUTCH OPERATION
Perform auto active test of IPDM E/R. Refer to PCS-10, "
CONSULT Function (IPDM E/R)".
Is the inspection result normal?
YES >> Inspection End.
NO >> Refer to HAC-45, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000012430748
Regarding Wiring Diagram information, refer to HAC-22, "Wiring Diagram".
1.CHECK FUSE
Check 10A fuse (No. 42, located in IPDM E/R).
NOTE:
Refer to PG-60, "
IPDM E/R Terminal Arrangement".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace the blown fuse after repairing the affected circuit.
2.CHECK MAGNET CLUTCH
1. Turn ignition switch OFF.
2. Disconnect compressor connector.
3. Directly apply battery voltage to the magnet clut ch. Check for operation visually and by sound.
Does it operate normally?
YES >> GO TO 3.
NO >> Replace magnet clutch. Refer to HA-26, "
Removal and Installation".
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.
