U0184 on RAM
Lost Communication With Radio
U0184 on RAM vehicles indicates lost communication with radio. Au7o has documented this code across 1 RAM model — most commonly on 1500. 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

- Uconnect Center Touchscreen Freezing, Random Rebooting, and Blank/Ghost-Touch Display2019-2024
The center-stack Uconnect infotainment touchscreen (8.4-inch and 12-inch units) randomly goes blank, freezes on the boot logo, reboots on its own while driving, or exhibits 'ghost touching' where it registers phantom presses. Because Uconnect also controls the HVAC temperature, backup camera, radio, phone/Bluetooth, and navigation on these trucks, a locked or dead screen can leave the driver unable to adjust climate or view the reversing camera. The root cause is generally a software/firmware fault in the head unit or telematics box (a Feb 2018 OTA update notably caused thousands of units to reboot roughly every 45 seconds), occasionally aggravated by a half-installed update or a loose/corroded harness connection. This is the center infotainment display and is distinct from the digital gauge/instrument cluster blank-out recall.
- Uconnect 8.4 infotainment freezes/reboots and backup-camera glitches2019-2023
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.

What does U0184 mean on 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 specifically, this code is documented across 1 model.
What causes U0184 on RAM vehicles?▼
Common causes on RAM: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix U0184 on a RAM?▼
Repair costs vary widely depending on the root cause and specific RAM model.
