MODE DOOR CONTROL SYSTEM
Description
INFOID:0000000000954638
SYSTEM DESCRIPTION
Component Parts
Mode door control system components are:
• Auto amp.
• Mode door motor (LCU)
• A/C LAN system (PBR built-in mode door motor, high-level ventilator door motor, air mix door motor and
intake door motor)
• In-vehicle sensor
• OAT sensor
• Sunload sensor
• Intake sensor
System Operation
• The auto amp. receives data from each of the sensors.
• The auto amp. sends air mix door, mode door, high-level ventilator door and intake door opening angle data
to the air mix door motor LCUs, mode door motor LCU, high-level ventilator door motor LCU and intake door
motor LCU.
• The air mix door motors, mode door motor, high-level ventilator door motor and intake door motor read their
respective signals according to the address signal. Opening angle indication signals received from the 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.
• Subsequently, HOT/COLD, DEF/VENT, OPEN/SHUT and FRE/REC operation is selected. The new selec-
tion data are returned to the auto amp.
