U0184 on Lincoln
Lost Communication With Radio
U0184 on Lincoln vehicles indicates lost communication with radio. Au7o has documented this code across 2 Lincoln models — most commonly on Aviator, Nautilus. This network code means a module stopped receiving expected communication messages from the radio/audio module over the vehicle's data bus. When the radio module goes offline or its bus connection fails, this code is logged. On some vehicles the audio module also acts as a network gateway, so its loss can trigger several related communication codes. Symptoms are typically a dead or unresponsive radio/infotainment system; it does not affect drivability.
Common Causes of U0184
- •Loss of power or ground to the radio/audio module
- •Blown radio fuse
- •Wiring or connector fault on the communication bus
- •Faulty radio/audio control module
- •Corroded or loose module connector
- •Network/bus wiring short affecting multiple modules
U0184 on Lincoln by Model
Lincoln Aviator(1 issue)
- Lack of Audio with Rear-Liftgate or Spare-Tire Water Leak - TSB 23-21812020-2023
Some 2020-2023 Aviators may exhibit lack of audio after rainfall or a car wash together with water in the rear-liftgate area or spare-tire area. Ford TSB 23-2181 directs Aviator-specific inspection of the power-liftgate grommet, margin seal and pushpins, electrical-wiring grommet, rear washer hose, body-hole plugs, BLIS-module seating, and BLIS harness grommets. The bulletin calls for ACM replacement when right-side water is present; it does not establish water damage as the cause of every audio outage.
Lincoln Nautilus(1 issue)
- SYNC 3 / APIM infotainment freezes, black-screens, and reboots2019-2023
First-generation Nautilus owners widely report the SYNC 3 center touchscreen freezing, going completely black, or spontaneously rebooting while driving — sometimes leaving only the backup camera working. Symptoms point to memory corruption in the APIM (Accessory Protocol Interface Module / SYNC module) software rather than the display panel itself, so a black or frozen screen usually traces to the APIM. Distinct from the 2024+ panoramic/center-display reboot recall (25V337), which is the newer multimedia module on the redesigned model.
