Update
Added a new photo to the album!
Accessing the Service Mode (hold finger on Software screen, put foot on brake pedal, type in "service") allowed me to access the Driver Assist diagnostics screen and reset the DAS. Doing this several times in a row, each time observing that the backup camera started working for a few seconds to a few minutes after each reset, led me to wonder if I might be able to start a drive while the camera was online and that might unlock a normal drive. I tested this theory and indeed the following features recovered for the brief period when the backup camera was online:
- Car agents and features
- TAAC and NoA
As soon as the camera crashes again, these features stop working. Seems like a software bug, especially since "Reset DAS" consistently brings it back online. Maybe the data bus is getting overloaded with too much traffic?
