Mazda 6 cars are equipped with an air conditioning system with automatic control. The air conditioning system uses a full-flow aluminum heater radiator with linear circulation. The efficiency of heat exchange is increased by using an additional evaporator.
The air conditioner electronic control unit has a self-diagnosis function. A failure in the system is recorded in the diagnostic trouble code memory, while the air conditioner switch indicator operates in a flashing mode.
