Mazda CX-5 Service & Repair Manual: Airflow Mode Control [Full Auto Air Conditioner]
Purpose
-
The airflow mode control changes the airflow mode according to the vehicle environment.
Function
-
The airflow mode control drives the airflow mode actuator according to the mode switch, defroster switch, and the vehicle environment and switches the position of the airflow mode door.
-
The airflow mode control has automatic and manual controls.
-
The airflow mode automatic control performs the following correction:
-
Engine coolant temperature correction (warm-up correction)
Airflow mode automatic control
-
The climate control unit determines the airflow mode based on the current air mix actuator opening angle and solar radiation amount.
-
Determined value used for the airflow mode is changed according to the signal from the solar radiation sensor.
Airflow mode manual control
-
The climate control unit switches the airflow mode based on the MODE switch operation.

Correction
-
Engine coolant temperature correction (warm-up correction)
-
The engine coolant temperature correction (warm-up correction) prevents cold air from coming out of the lower vents after engine start in winter.
-
The engine coolant temperature correction (warm-up correction) switches the airflow mode according to the increase in the engine coolant temperature.
