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.
