System Diagram

INFOID:0000000003846309

System Description

INFOID:0000000003846310

The mode door is automatically controlled by the temperature setting, ambient temperature, in-vehicle temper-
ature, intake temperature and amount of sunload.

SYSTEM OPERATION

• The A/C auto amp. receives data from each of the sensors.
• The A/C auto amp. sends the air mix door, the mode door and the intake door opening angle data to the air

mix door motor LCUs, the mode door motor LCU and the intake door motor LCU.

• The air mix door motors, the mode door motor and the intake door motor read their respective signals

according to the address signal. Opening angle indication signals received from the A/C auto amp. and each
of the motor position sensors are compared by the LCUs in each door motor with the existing decision and
opening angles.

• Next, HOT/COLD, DEF/VENT, OPEN/SHUT or FRE/REC operations is selected. The newly selected data is

returned to the A/C auto amp.
