Bulletin Summary
Some 2025-2026 Nautilus vehicles with heated-only front seats (minor feature code BY1AC) (not heated and cooled) may set diagnostic trouble codes (DTCs) B103A:15, B1034:13, B1036:13, and B1038:15 in the heating, ventilation, and air conditioning (HVAC) module when a diagnostic self-test is performed. These DTCs have no effect on functionality and should be ignored if no other DTCs are present in the HVAC module and no symptoms are present. Continue with diagnosing any other HVAC DTCs first. No further service action is required.<br /><br /> To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner in the Professional Technician System (PTS).
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
