The AHU receives a 12 V fused power supply from the Battery Junction Box (BJB) and the Quiescent Current Control Module (QCCM).
High Speed (HS) Controller Area Network (CAN) comfort system bus connections provide communication with other system control modules. For example inputs from the Parking Assist Control Module (PACM) for sound generation and display on the TS.
The AHU uses Automotive Pixel Link 2 (APIX2) which is a new protocol for video output to the Touch Screen (TS). APIX2 is a high speed digital serial link capable of communicating up to 3 Gigabit/second of digital video data. The serial link can support simultaneous video, audio and data transmission from the AHU and the TS.
