- except CODE (581b) Convenience automatic air conditioning

Component Identification:

Via the A/C bus (KB) the fresh and recirculated air flap actuator motor (M2/5), the left blending air flap actuator motor (M2/6), the right blending air flap actuator motor (M2/7), the left and right footwell flaps actuator motor (M2/15), the left and right defroster flaps actuator motor (M2/16) and the fresh air flaps actuator motor (M2/21) for the air distribution and the blower motor (A32m1) are regulated via the blower regulator (A32n1) for the air flow by the AAC [KLA] control and operating unit (N22).
Apart from this, data is sent from the air humidity sensor (B31/2) over the AC bus (KB) to the AAC control and operating unit (N22).

The AAC control and operating unit (N22) is networked with all the vehicle electronics via the CAN-B (CAN B). This in turn makes it possible to incorporate additional climate-relevant influences, in order to improve the regulation quality and to lower power consumption. All the control units which fulfill a task in the control of the automatic air conditioning are connected to each other via the CAN-B (CAN B).
