Manufacturer summary

Original wording in English

Some 2024-2026 Nautilus vehicles may experience an "Advance Front Lighting Features Temporarily Unavailable" message with diagnostic trouble codes (DTC) B155A and/or B1559 stored in the headlamp control module (HCM). It is no longer recommended to replace the HCM to correct this condition. Workshop Manual (WSM), Section 417-01 > Diagnosis and Testing > Pinpoint Test (PPT) W: "Headlamp Internal Failures - Multiple HCM DTC" has been updated to improve diagnostics for this condition.

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.
