Manufacturer summary

Original wording in English

Some 2023 F-Super Duty vehicles may set 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 communication error to the IPMA. Replacement or reprogramming of the IPMA will not resolve this condition. 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.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
