HAC-34 < COMPONENT DIAGNOSIS > [AUTOMATIC AIR CONDITIONER] AIR MIX DOOR MOTOR AIR MIX DOOR MOTOR Description INFOID:0000000004498205 SYSTEM DESCRIPTION Component Parts Air mix door control system components are: • Front air control • Air mix door motors (LCU) • In-vehicle sensor • Ambient sensor • Sunload sensor • Intake sensor System Operation The front air control receives data from each of the sensors. The front air control sends air mix door, mode door and intake door motor opening angle data to the air mix door motors LCU, mode door motor LCU and intake door motor LCU. The air mix door motor, mode door motor and intake door motor read their respective signals according to the address signal. Opening angle indication signals received from the front air control and each of the motor posi- tion sensors are compared by the LCUs in each motor with the existing decision and opening angles. Subse- quently, HOT/COLD or DEFROST/VENT or FRESH/RECIRCULATION operation is selected. The new selection data is returned to the front air control.
