DTC B200FFA: Internal malfunction (symptom 282648 or 282649).

Replacing the driver assist systems control unit -J1121- (address word 00A5) because of DTC B200FFA
– Internal malfunction (symptom 282648 or 282649) will NOT fix the customer complaint.

Technical Background 1
Deviation in the diagnostic capability of the driver assist systems control unit -J1121-.

Production Solution
Not applicable.

Service
Scenario 1:
An individual overhead view camera is fogged up or the image from it is cloudy or blurry.
Because of deviations in the diagnostic capability of the driver assist systems control unit -J1121-, an individual
overhead view camera (e.g., faulty overhead view camera, short 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 above DTCs are
logged.

Technical Service Bulletin
If necessary, replace the fogged/blurry overhead view camera alongside the adapter wiring harness and take
clear pictures of the complaint.

Please note that during the following checks, the vehicle must enter bus sleep after each step so that
the overhead view camera system is reinitialized.

Replacing the driver assist systems control unit -J1121- without clear findings will NOT resolve the
issue.

Scenario 2:
Several DTCs about various cameras are stored:
Because of deviations in the diagnostic capability of the driver assist systems control unit -J1121-, an individual
overhead view camera (e.g., faulty overhead view camera, short 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 above DTCs are
logged.
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 operate 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.
This should point to the affected camera harness(es) branch(es) 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.
If no cause can be located, the following measures must be performed to narrow down the cause:
•

Swap an individual overhead view camera with another one (e.g., -R244- with -R245-) to rule out a faulty
overhead view camera.

•

Swap the video cable connection on the driver assist systems control unit -J1121- with another one (e.g.,
video cable of -R244- with video cable of -R245-) to rule out a faulty video cable. The connector housing on
the video cable must be removed to do this.

•

If it is not possible to locate the harness causing the issue using the procedure described in section 2, please
refer to TSB 2076264.

Technical Service Bulletin
Please note that during the following checks, the vehicle must enter bus sleep after each step so that
the overhead view camera system is reinitialized.

Replacing driver assist systems control unit -J1121- without clear findings will NOT resolve the issue.
Scenario 3:
A single DTC is logged for one individual overhead view camera (there are no other DTCs)
Perform a bus sleep cycle to reinitialize the control module for driver assist systems -J1121-.
Activate the overhead view camera system, then operate 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 (otherwise, continue with Scenario 2), 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.
If no cause can be located, the following measures must be performed to narrow down the cause:
•

Swap an individual overhead view camera with another one (e.g., -R244- with -R245-) to rule out a faulty
overhead view camera.

•

Swap the video cable connection on the driver assist systems control unit -J1121- with another one (e.g.,
video cable of -R244- with video cable of -R245-) to rule out a faulty video cable. The connector housing on
the video cable must be removed to do this.

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.

Please note that during the following checks, the vehicle must enter bus sleep after each step so that
the overhead view camera system is reinitialized.
