Some 2024 Nautilus vehicles may exhibit diagnostic trouble code (DTC) B1578:89 in the image processing module A (IPMA) when a diagnostic self-test is performed. This may be due to an internal module chip reboot that will recover by itself. B1578:89 has no effect on functionality. Replacement or reprogramming of the IPMA will not resolve this condition. Engineering is currently working on a solution and a software update is expected in Q2 2024. Continue to monitor OASIS for additional information.

B1578:89 should be ignored if: no other DTCs are present in the IPMA, the malfunction indicator lamp (MIL) is not illuminated while the engine is running, and no drivability concerns are present. No further service action is required.
