U0184 on Honda
Lost Communication With Radio
U0184 on Honda vehicles indicates lost communication with radio. Au7o has documented this code across 2 Honda models — most commonly on Accord, Odyssey. 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 Honda by Model
Honda Accord(1 issue)
- Display Audio / Apple CarPlay Infotainment Freezing, Rebooting, and Blank Screen2016-2017
2016-2017 Accords with the upper Display Audio screen suffer frequent infotainment faults: the screen freezes, the unit spontaneously reboots, the whole system goes blank, audio drops out, and Apple CarPlay shows distorted/garbled visuals or fails to connect. Honda issued Service Bulletin 16-059 addressing numerous software issues (blank screen, reboots, freezing, no sound, Bluetooth/XM faults) on EX, EX-L and Touring trims. Owners also suspect an underlying head-unit overheating/cooling design flaw that aggravates CarPlay crashes. While not a safety recall, it is one of the most-reported complaints for these model years.
Honda Odyssey(2 issues)
- Infotainment Black Screen / MOST Connector Failure2014-2023
Infotainment system experiences black screens, crashes, freezes, and complete failure due to faulty FAKRA connectors in MOST (Media Oriented Systems Transport) communication network. Improperly designed MOST coaxial cable causes deformed terminals and poor/lost connections. If MOST communication lost for 20+ seconds, rearview camera fails when in reverse.
- Backup Camera / MOST Communication Failure2018-2023
Media Oriented Systems Transport (MOST) coaxial cable connector improperly designed and manufactured, causing deformed terminals and poor/lost connections between audio display unit and vehicle cable connector. When MOST communication lost for 20+ seconds, rearview camera function fails when shifted into reverse, creating serious safety hazard as driver cannot see behind vehicle.
