2022-2026 Audi Overhead View Camera Malfunction TSB 2055188/10

Important Warnings for Owners

Audi has issued specific warnings regarding the diagnosis and repair of overhead view camera issues:

• Do not replace the control unit prematurely: "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." Similarly, "Replacing the driver assist systems control unit -J1121- without clear findings will NOT resolve the issue."
• Bus Sleep Cycle Required: "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."

Symptoms of Overhead View Camera Malfunction

Owners of affected 2022-2026 Audi vehicles may notice that their Audi e-tron camera inoperative or other overhead view cameras are not functioning correctly. Common symptoms include:

• "The overhead view camera does not work (sporadically or statically)"
• "One of the overhead view cameras is fogged up."
• The camera "picture is blurry or fogged up" or appears cloudy.

Fault Codes / DTCs

When the overhead view camera system malfunctions, the driver assist systems control unit -J1121- (address word 00A5) may store one or more of the following Diagnostic Trouble Codes (DTCs):

Fault	Description
B200FFA	Internal malfunction (symptom 282648 or 282649)
B127C04	Front overhead view camera
C12AE02	Front overhead view camera video cable signal error
B127C4B	Front overhead view camera excess temperature
B127D04	Rear overhead view camera
C12AF02	Rear overhead view camera video cable signal error
B127D4B	Rear overhead view camera excess temperature
B127E04	Left overhead view camera
C12B002	Left overhead view camera video cable signal error
B127E4B	Left overhead view camera excess temperature
B127F04	Right overhead view camera
C12B102	Right overhead view camera video cable signal error
B127F4B	Right overhead view camera excess temperature

Diagnosis and Trigger Conditions

These issues arise from deviations in the diagnostic capability of the driver assist systems control unit -J1121-. This can lead to a partial or complete failure of the overhead view camera system, even if the individual camera or its wiring is the root cause. The presence of one or more of the listed DTCs indicates a problem with the camera system.

Repair Procedure Summary

Technical Service Bulletin 2055188/10 outlines specific diagnostic and repair steps depending on the symptoms and DTCs present. The process involves three main scenarios:

Scenario 1: Individual Camera Fogged or Blurry

If a single overhead view camera is fogged, cloudy, or blurry, the technician will replace the affected camera along with its adapter wiring harness. Clear pictures of the complaint must be taken before and after the repair.

Scenario 2: Multiple DTCs Stored

When several DTCs related to various cameras are stored, the technician will perform a systematic isolation process:

1. Isolate the fault: All cameras are disconnected from the driver assist systems control unit -J1121-. Each camera is then reconnected individually.
2. Bus sleep cycle: After connecting each camera, the vehicle must enter a bus sleep cycle to reinitialize the -J1121- control unit.
3. Test and verify: For each connected camera, the overhead view camera system is activated, and the doors/hood/trunk are operated (depending on the camera's position). The MMI screen is checked to ensure the image displays correctly and without interruption.
4. Inspect wiring: Once the faulty camera branch is identified, all coupling points and coax cables between the -J1121- control unit and the affected cameras (-R243-, -R244-, -R245-, -R246-) are inspected for loose connectors, pushed-back pins, corrosion, or damage.
5. Component swapping (if no cause found): If no clear cause is located, the technician may swap an individual overhead view camera with another or swap video cable connections on the -J1121- control unit to further narrow down the issue.

Scenario 3: Single DTC for One Camera

If only one DTC is logged for a single overhead view camera, the following steps are performed:

1. Bus sleep cycle: A bus sleep cycle is initiated to reinitialize the -J1121- control module.
2. Test and verify: The overhead view camera system is activated, and the doors/hood/trunk are operated. The MMI screen is checked for correct and uninterrupted image display.
3. Inspect wiring: If the DTC persists and is identical to the initial one, the coupling points and coax cables between the -J1121- control unit and the affected camera are checked for loose connectors, pushed-back pins, corrosion, or damage.
4. Component swapping (if no cause found): If no clear cause is located, the technician may swap the individual overhead view camera or its video cable connection with another to isolate the fault. The connector housing on the video cable must be removed for this step.
5. Wiring overlay (if problem persists): If no problem is identified with the camera, the wiring is double-checked 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, the coax wire to the camera is overlaid.

Required Parts

While specific part numbers are not listed in the TSB, the repair procedure may require:

• Replacement overhead view camera(s)
• Adapter wiring harness(es)
