| Compressor |
ECV (Electrical Control Valve) |
ECV (electrical control valve) is installed on the compressor and controls it for emitting appropriate amount of refrigerant when necessary. |
| Magnet clutch |
- Magnet clutch is the device that drives the compressor with the signal from IPDM E/R.
- Compressor is driven by the magnet clutch which is magnetized by electric power supply.

| Ambient sensor |
Ambient sensor measures ambient air temperature. This sensor uses thermistor that decreases electrical resistance as temperature increases. |
| AV control unit |
AV control unit transmits A/C switch operation signal to A/C auto amp. via CAN communication line. |
| A/C auto amp. |
A/C auto amp. controls air conditioning system by inputting and calculating signals from each sensor and each switch. A/C auto amp. has self-diagnosis function. Diagnosis of air conditioning system can be performed quickly. |
| BCM |
BCM transmits key ID signal to A/C auto amp. via CAN communication line. |
| Display |
Display indicates operation status of air conditioning system. Display has touch panel function that can be used to control air conditioning system. |
| ECM |
ECM controls compressor according to status of engine and refrigerant. |
| Engine coolant temperature sensor |
Engine coolant temperature sensor measures engine coolant temperature. This sensor uses thermistor that decreases electrical resistance as temperature increases. |
| In-vehicle sensor |
In-vehicle sensor measures temperature of intake air through aspirator to passenger room. This sensor uses thermistor that decreases electrical resistance as temperature increases. |
| IPDM E/R |
A/C relay is integrated in IPDM E/R. IPDM E/R operates A/C relay when A/C compressor request signal is received from ECM via CAN communication line. |
| Multifunction switch |
Multifunction switch integrates A/C controller and AV operation switch. A/C switch operation signal is transmitted from multifunction switch to AV control unit via communication line. |
| Refrigerant pressure sensor |
Refer to
REFRIGERANT PRESSURE SENSOR . |
| Sunload sensor |
Sunload sensor measures sunload amount. This sensor is a dual system so that sunload for driver side and passenger side are measured separately. This sensor converts sunload amount to voltage signal by photodiode and transmits to A/C auto amp. |
