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)".

INSUFFICIENT COOLING
INSUFFICIENT COOLING
DescriptionINFOID:0000000012430750
Symptom
• Insufficient cooling
• No cool air comes out. (Air flow volume is normal.)
Diagnosis ProcedureINFOID:0000000012430751
NOTE:
Perform self-diagnosis with CONSULT before performing
symptom diagnosis. If any malfunction result or DTC
is detected, perform the corresponding diagnosis.
1.CHECK MAGNET CLUTCH OPERATION
1. Turn ignition switch ON.
2. Turn fan control dial ON.
3. Press A/C switch.
4. Check that A/C indicator turns ON. Check visually and by sound that compressor operates.
5. Press A/C switch again.
6. Check that A/C indicator turns OFF. Check that compressor stops.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Check compressor operation. Refer to HAC-50, "
Diagnosis Procedure".
2.CHECK DRIVE BELT
Check tension of drive belt. Refer to EM-17, "
Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Adjust or replace drive belt depending on the inspection results.
