U0184 on RAM by model: symptoms, diagnosis and fix
5th-gen (DT) RAM 1500 trucks with the Uconnect 8.4 (and 12-inch) systems are widely reported to randomly reboot, freeze on the RAM logo, lose audio (sound cutting out every couple of seconds), and show backup-camera faults such as a blue screen, blank image, a large yellow square, or significant camera delay. Failures cluster in temperature extremes (below ~15F or above ~90F) and can occur at startup or after the system warms up. Some early trucks also had screen de-lamination/ghost-imaging hardware defects requiring radio replacement. A software update (TSB 08-003-19) was issued to address display freezing/glitches.
Common Symptoms
- Screen randomly reboots or freezes on the RAM logo
- Audio cuts out intermittently every couple of seconds
- Backup camera shows blue/blank screen, yellow square, or long delay
- Worse behavior in very cold or very hot weather
- Screen de-lamination or ghost/burn-in images (early trucks)
How to Fix
Perform a Uconnect soft reset (key to RUN, then hold the volume knob and tuner knob together ~10-20 seconds) to clear a frozen screen. Have the dealer install the latest Uconnect software (per TSB 08-003-19) which addresses many freeze/reboot/camera cases. Persistent hardware faults (de-lamination, ghosting, dead camera image) require radio or camera replacement, ideally under the basic (bumper-to-bumper) warranty.

Frequently asked questions
What does U0184 mean on a RAM?
U0184 stands for "Lost Communication With Radio." 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. On RAM it is documented across 1 model: 1500.
What are the most common causes of U0184?
The most common causes of U0184 are: 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. The specific cause varies by vehicle.
How much does it cost to fix U0184 on a RAM?
Repair costs vary widely with the root cause and RAM model; each issue on this page carries its own estimate where one is published.
