Reversing camera (RFK), function - GF54.65-P-0005LE

MODEL 216.3, 221.0/1 with CODE (218) Backup camera except CODE (498) Japan version as of model year 2009/YoM 08 

Function requirements, general 

• Circuit 15 ON
• Reversing camera system activated over the instrument cluster (A1)
• Reverse gear engaged

Reversing camera, general 

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

When first put into operation, during work on the reversing camera (B84/3) or work on the trunk lid, the reversing camera must be recalibrated using the diagnostic tester.

Reversing camera function sequence 

The "reverse gear engaged" signal is sent by the EGS control unit (N15/3) (with transmission 722.6) or the fully integrated transmission control unit (VGS) (Y3/8n4) (with transmission 722.9) via the drive train CAN (CAN C) to the CDI control unit (N3/9) (with diesel engine) or to the ME-SFI [ME] control unit (N3/10) (with gasoline engine). The CDI control unit or the ME-SFI [ME] control unit forwards the signal via the chassis CAN (CAN E) to the central gateway control unit (N93) which routes the signal to the interior CAN (CAN B).

The rear SAM control unit with fuse and relay module (N10/2) then activates the reversing camera power supply module (N66/10) which supplies power to the reversing camera. The camera images captured by the reversing camera are transmitted to the COMAND controller unit (A40/3) via the reversing camera power supply module.

The guide lines have the following meaning:

• Blue guide line:

  Extended lateral line of vehicle

• Yellow guide line:

  Distance from vehicle s = 1 m

• Red guide line:

  Distance from vehicle s = 0.25 m

The COMAND controller unit then activates the COMAND display (A40/8) (without code (867) SPLITVIEW) or the SPLITVIEW display (A40/10) (with code (867) SPLITVIEW) via the telematics CAN (CAN A). The image data is transmitted directly by the COMAND controller unit via the CVBS interface to the COMAND display where it is displayed.

If the trunk lid is open, the message "Trunk lid open" appears in the COMAND display or the SPLITVIEW display.
