Bulletin Summary
Some 2020-2024 Aviator vehicles equipped with auto air refresh option (minor feature code G1DAG) may exhibit a buzzing/clicking/humming/ticking sound from the OHC and/or diagnostic trouble code (DTC) P24AE in the heating ventilation and air conditioning (HVAC) module. To confirm if 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). If diagnostics lead to the in-vehicle temperature and humidity sensor as the causal part, a new lower level part is available. It is not necessary to replace the OHC assembly if only the sensor is suspect. Use part number L1MZ-19F666-A to resolve the concern.
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.
