Reversing camera (RFK), function - GF54.65-P-0005LEJ (2 Of 2)
MODEL 221.0/1, 216.3
with CODE (218) Backup camera
with CODE (498) Japan version
as of model year 2009
/YoM 08
Function requirements, general
- Reversing camera system activated over the instrument cluster (A1)
- Trunk lid closed
- Circuit 15 ON
The status of circuit 15 is sent by the EIS [EZS] control unit (N73) to the interior CAN (CAN B).
The status of the trunk lid is detected by the trunk lid rotary tumbler microswitch (M14/7s3) which is read in by the rear SAM control unit with fuse and relay module (N10/2).
The rear SAM control unit makes the information available on the interior CAN.
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.
If the trunk lid is open, the message "Trunk lid open" appears in the COMMAND display (A40/8).
Reversing camera function sequence
The reversing camera system enables the driver to select between two parking modes:
- Right angle parking (reverse parking)
- Lengthwise parking (parallel parking)
The reversing camera system is activated by engaging gear range "R".
The "reverse gear engaged" signal is sent by the EGS control unit (N15/3) (with transmission 722.6) or by the fully integrated transmission control unit (VGS) (Y3/8n4) (with transmission 722.9) via the drive train CAN (CAN C) to the ME-SFI [ME] control unit (N3/10). The ME-SFI [ME] control unit forwards the signal via the chassis CAN (CAN E) to the central gateway control unit (N93) which forwards the signal via the interior CAN (CAN B) to the reversing camera control unit (N66/2). The rear SAM control unit with fuse and relay module (N10/2) passes on the status of the trunk lid via the interior CAN.
The reversing camera control unit then supplies power to the reversing camera. The camera images captured by the reversing camera are read in and evaluated by the reversing camera control unit.
Additionally, guide lines are calculated by the reversing camera control unit using the steering angle and stored vehicle parameters, and displayed in the recorded images.
The rotation angle is recorded by the steering angle sensor (N49). The steering column tube module (N80) reads in the signals of the steering angle sensor and sends them via the chassis CAN to the central gateway control unit (N93). The front central gateway control unit forwards the information via the interior CAN to the reversing camera control unit.
The signals from the following sensors are also evaluated:
- Left front rpm sensor (L6/1)
- Right front rpm sensor (L6/2)
- Left rear rpm sensor (L6/3)
- Right rear rpm sensor (L6/4)
The ESP control unit (N47-5) (except model 221.095/195) or the regenerative braking system control unit (N30/6) (model 221.095/195) reads in the rpm sensors directly and passes the information on to the central gateway control unit via the chassis CAN. The front central gateway control unit forwards the information via the interior CAN to the reversing camera control unit.
The processed images are transmitted to the COMMAND controller unit (A40/3). The COMMAND controller unit then activates the COMMAND display via the telematics CAN (CAN A). The image data is transmitted directly by the COMMAND controller unit via the LVDS interface (Low-Voltage Differential Signaling) to the COMMAND display where it is displayed.
The operating instructions for the parking procedure can be found in the document "Reversing camera (RFK) operating instructions".
A voice output can also be selected in this national version. The voice output takes place in the Japanese or English and is activated or deactivated in the instrument cluster.
Similarly, the warning messages in the COMMAND display can also be given in Japanese or English.
