GF83.40-P-0004-02Q Comfort Automatic Air Conditioning (C-AAC) Notes On AC Bus
- with CODE (581b) Convenience automatic air conditioning







The fresh air flaps and recirculated air flaps actuator motor (M2/5), the left blending air flap actuator motor (M2/6), the right blending air flap actuator motor (M2/7), the left defroster vent flap actuator motor (M2/8), the right defroster vent flap actuator motor (M2/9), the left footwell flap actuator motor (M2/10), the right footwell flap actuator motor (M2/11), the left vent flap actuator motor (M2/19), the right vent flap actuator motor (M2/20) and the activated charcoal filter flap adjustment motor (A32m2) for the air distribution are controlled by the AC bus and the blower motor (A32m1) is controlled via the blower regulator (A32n1) for air volume by the comfort AAC [KLA] control and operating module (N22/7).

Furthermore, via the AC bus signals from the C-AAC sun sensor 4 in total) (B32/2) and from the C-AAC [K-KLA] multifunction sensor (B31) are read in for regulation of the comfort automatic air conditioning and passed on to the CAN class B via the front SAM control unit with fuse and relay module.
The comfort AAC control and operating module (N22/7) is networked with the entire vehicle electronics via CAN class B. So it is possible to incorporate additional influences relevant to climate in order to improve the control quality and to lower the energy consumption. All the control modules which fulfill a task in the control of the automatic air conditioning are connected to each other via the CAN class B.
