Bulletin Summary
Some 2020-2024 Explorer/Aviator vehicles may exhibit poor speaker sound quality and/or tick-tock noise while activating turn signals and streaming audio over Bluetooth. Customers may describe static heard during a Bluetooth phone call or a door speaker buzz or tick noise with the pulse of the turn signal. This may be due to concerns with the 14401/14A005 wiring harnesses or connector damage. Prior to the replacement of the affected speaker, inspect for incorrect pin fit/crimp, bent pins, broken wire strands, or other damage at inline connectors C202, C2383A, and/or C4240B. These circuits join the accessory protocol interface module (APIM) and audio front control module (ACM) components. If wiring/connector concerns are found, repair per Wiring Diagram Cell 5.
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.
