Component |
Description |
|
|
Ambient sensor |
Ambient sensor measures ambient air temperature. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. |
|
|
Display control unit |
Display control unit transmits front A/C control operation signal to A/C auto amp. via CAN communication line. |
|
|
A/C auto amp. |
A/C auto amp. controls front automatic air conditioning system by inputting and calculating signals from each sensor and each switch. A/C auto amp. has self-diagnosis function. Diagnosis of front automatic air conditioning system can be performed quickly. |
|
|
BCM |
BCM transmits key ID signal to A/C auto amp. via CAN communication line. |
|
|
Blower unit |
Front blower motor |
Refer to Component Description .. |
|
Intake door motor |
The LCU (Local Control Unit) is installed to intake door motor so as to perform the multiplex communication control (LIN). Refer to System Description .. |
|
|
Combination meter |
Combination meter transmits vehicle speed signal to A/C auto amp. via CAN communication line. |
|
|
ECM |
ECM controls compressor according to status of engine and refrigerant. ECM transmits engine coolant temperature signal to A/C auto amp. via CAN communication line. |
|
|
Engine coolant temperature sensor |
Engine coolant temperature sensor measures engine coolant temperature. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. |
|
|
Front display |
Front display indicates operation status of front automatic air conditioning system. |
|
|
Front in-vehicle sensor |
Front in-vehicle sensor measures temperature of intake air that flows through aspirator to passenger room. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. |
|
|
Heater & cooling unit assembly |
Aspirator |
Refer to Component Description .. |
|
Front air mix door motor (Driver side) |
The LCU (Local Control Unit) is installed to front air mix door motor (driver side) so as to perform the multiplex communication control (LIN). Refer to System Description .. |
|
|
Front air mix door motor (Passenger side) |
The LCU (Local Control Unit) is installed to front air mix door motor (passenger side) so as to perform the multiplex communication control (LIN). Refer to System Description .. |
|
|
Front mode door motor |
The LCU (Local Control Unit) is installed to front mode door motor so as to perform the multiplex communication control (LIN). Refer to System Description .. |
|
|
Intake sensor |
Intake sensor measures temperature of front evaporator fin temperature. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases. |
|
|
Upper ventilator door motor |
The LCU (Local Control Unit) is installed to upper ventilator door motor so as to perform the multiplex communication control (LIN). Refer to System Description .. |
|
|
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. |
|
|
Magnet clutch |
The 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. IPDM controls magnet clutch by turning the built in A/C relay to ON <=> OFF according to ECM request. |
|
|
Preset switch |
Preset switch is integrated with front A/C control and AV operation switch. Front A/C control operation signal is transmitted from preset switch to display control unit via communication line. |
|
|
Refrigerant pressure sensor |
Refer to Component Description .. |
|
|
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. |
