Function requirements, general 

• Circuit 15 ON
• COMAND operating, display and controller unit (A40/3) switched on
• Reverse gear engaged

Status of circuit 15 is provided by EIS [EZS] control unit (N73) on interior CAN (CAN B).

Reversing camera, general 

The reversing camera system assists the driver when reverse parking and when backing up.

Reversing camera function sequence 

The "Reverse gear engaged" signal" is transmitted from the intelligent servo module for DIRECT SELECT (A80) on the engine compartment CAN (CAN C).

This signal is routed to the interior CAN by the central gateway control unit (N93).

The rear SAM control unit (N10/8) then activates the reversing camera power supply module (N66/10), which supplies power to the reversing camera (B84/3).

The camera pictures recorded by the reversing camera are transited and displayed as Color Video Baseband Signal (FBAS) via the power supply module for reversing camera to the COMAND operating, display and controller unit.

On vehicles up to 30.6.07 with code (863) Digital analog TV-Tuner the recorded camera pictures from the power supply module for the reversing camera are transmitted via the TV combination tuner (analog/digital) (A90/1) to the COMAND operating, display and controller unit.
