and/or
• DTC B200FFA (internal malfunction) with symptom code 282648 or 282649.

Technical Background
Because of shortcomings in the diagnostic capability of the driver assist systems control unit -J1121-, a problem
with an individual overhead view camera (e.g., faulty camera, short/open circuit in the video cable, water ingress,
etc., …) can cause a partial or complete failure of the overhead view camera system. All, or some of the DTC
entries above may be logged, even if only one camera is affected. Further, the blanked out camera on the MMI
screen may not be related to the defective camera branch.

Production Solution
Not applicable.

Scenario 1:
An individual overhead view camera is fogged up or the image from it is cloudy or blurry.

Technical Service Bulletin
Replace the fogged/blurry overhead view camera alongside the adapter wiring harness and take clear pictures
of the complaint.
Scenario 2:
Several or all DTCs listed in the table above are entered in the driver assist systems control unit -J1121-.
Due to shortcomings in the diagnostic capability of the driver assist systems control unit -J1121-, all or some of
the DTCs in the table above may be entered in address word 00A5. The entered DTCs or crossed out cameras
on the MMI display may not correspond to the defective camera branch.
In order to locate the fault, disconnect ALL cameras from the driver assist systems control unit -J1121- and then
connect each camera individually to the driver assist systems control unit.
Each time a different camera branch is connected, a bus sleep cycle must be performed in order to
reinitialize the driver assist systems control unit -J1121-.
For each camera, activate the overhead view camera system, then move the doors/hood/trunk (depending on
the position of the camera that is currently checked) and check at the same time that the image displays
correctly and uninterrupted on the MMI screen.
This should point to the affected camera branch in the vehicle.
Once the camera branch is identified, check all the coupling points and coax cables between the driver assist
systems control unit –J1121– and the affected overhead view camera (-R243-, -R244-, -R245-, -R246-) for loose
connectors, loose/pushed back pins, corrosion, or damage (e.g., around pinched/overbent/kinked coax cables
around the mirror feet).

Replacing cameras (-R243-, -R244-, -R245-, -R246-) or the driver assist systems control module (J1121-) will not resolve this customer complaint. Claims for replaced cameras or driver assist systems
control modules may be denied.
Scenario 3:
A single DTC is logged for one individual overhead view camera (without any other DTCs from the table
above)
Perform a bus sleep cycle to reinitialize the control module for driver assist systems -J1121-.
Activate the overhead view camera system, then move the doors/hood/trunk (depending on the position of the
camera that is currently checked) and at the same time, check that the image displays correctly and
uninterrupted on the MMI screen.
If the DTC persists and is identical to the initial DTC, check all the coupling points and coax cables between the
driver assist systems control unit -J1121- and the affected overhead view camera (-R243-, -R244-, -R245-, R246-) for loose connectors, loose/pushed back pins, corrosion, or damage (e.g., around
pinched/overbent/kinked coax cables around the mirror feet)
If no problem with the wiring can be identified, swap the affected overhead camera with another one. If the fault
follows the camera, replace the affected camera.

Technical Service Bulletin
If no problem with the camera can be identified, double check the wiring by removing the connector housing on
the -J1121- side of the coax wire and swapping it with a camera at a different position. If the fault follows the
swapped coax wire, overlay the coax wire to the camera.

Replacing the driver assist systems control module -J1121- will not resolve the customer complaint.
Claims for replaced driver assist systems control module -J1121- may be denied.
