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