Purpose
The magnetic clutch transmits the rotation force from the engine to the shaft in the A/C compressor.
Function
The magnetic clutch engages or disengages the magnetic clutch and the A/C turns on or off by switching the power transmission from the engine.
Construction
The magnetic clutch is installed to the A/C compressor.
The magnetic clutch consists of the following parts:
Pressure plate
A/C compressor pulley
Stator
Snap ring
Shim
Operation
Magnetic clutch disengagement
1. If there is no energization in the magnetic clutch stator from the A/C relay, the pressure plate cannot be engaged with the A/C compressor pulley because the magnetic clutch stator does not operate.
2. The rotation force from the drive belt is only transmitted to the A/C compressor pulley and the pulley spins.
Magnetic clutch engagement
1. If there is energization in the magnetic clutch stator from the A/C relay, the magnetic clutch stator operates and the pressure plate is engaged with the A/C compressor pulley.
2. The rotation force from the drive belt is transmitted to the compressor shaft through the pressure plate from the A/C compressor pulley.
Fail-safe
Function not equipped.
Barometric Pressure (Baro) Sensor Inspection
Voltage Inspection
NOTE:
Because the BARO sensor is integrated in the PCM, replacing the BARO sensor
includes replacement of the PCM.
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine off or on).
3. Verify that the BARO sensor output voltage (PID: BARO) is wi ...
Engine Tune Up
Engine Tune-up Preparation
NOTE:
If the accelerator pedal is depressed continuously for a specified time,
the engine speed may decrease to the idle speed. This is due to the fuel cut
control operation, which prevents overheating, and it does not indicate a malfunction.
