After a recent dealership visit for brake service and a 3G OTA update on a 2019 Honda Odyssey Elite, multiple error messages appeared, including Collision Mitigation, LKA, Adaptive Cruise Control, Lane Departure Mitigation, and Auto High Beam malfunctions. Additionally, the proximity key detection and navigation system’s home address were lost. The dealership initially attributed the DVD player malfunction to needing replacement and suggested a full system reset, which involved disconnecting and reconnecting the battery. Following this reset and a subsequent Honda Sensing OTA update, the camera sensor seemingly failed.
The dealership now claims the camera sensor requires replacement due to an “internal failure” indicated by error code U3000-49. The timing of the camera sensor failure, immediately following the dealership visit and system reset, raises concerns about a potential correlation between the service and the subsequent malfunctions. It’s suspected that the Honda Sensing OTA update, triggered after the battery reconnection, may have caused the camera to lose communication with the system.
What are the potential causes of a U3000-49 error code in a Honda vehicle, specifically after a system reset and OTA update? Could the OTA update itself have corrupted the camera sensor’s firmware or caused compatibility issues?
Are there any known service bulletins or technical documentation related to U3000-49 or similar camera sensor issues in 2019 Honda Odyssey models? Where can these resources be accessed?
What diagnostic steps can be taken to confirm the U3000-49 diagnosis and rule out other potential causes, such as loose connections, wiring harnesses, or fuse issues related to the camera system?
If the camera sensor replacement is indeed necessary, is there any recourse to hold the dealership accountable for potential damage caused during the initial service or subsequent updates? A case has been opened with Honda USA to investigate the matter further.
