HVAC System (Heater, Ventilator and A/C)
2) RHD VEHICLE:
! Air outlet control:
In the automatic air-conditioning mode, the air outlets are selected based on the TAO and TW and
the servo motors for actuating the air outlet switching dampers are controlled to achieve the se-
lected air outlet configuration. After the dampers have been moved, the potentiometer of each ser-
vo motor feeds back damper status information to the ECM. If necessary, the ECM actuates the
servo motor so that the actual damper position (SPO) corresponds to the target damper position
(SWO).
! Air outlet control in automatic air-conditioning mode:
The air outlets are selected based on the TAO for the FACE, BI-LEVEL and HEAT positions.
! Air outlet control when HEAT or BI-LEVEL position is automatically selected:
If the air flow calculated based on the TW is at the Lo level, the selected outlets are for the defrost-
ing operation (i.e., the outlet configuration for defrosting is invariably selected when the TW is low).
