U0184 to U0198: radio, audio, entertainment and telematics modules
A module stopped hearing from the radio, the antenna module, the amplifier, a disc player, a digital audio module, a satellite radio receiver, the rear seat entertainment, the phone module or the telematics unit.
SeverityLowLittle risk to the car, but the fault stays until it is repaired.
Can you keep driving?Safe to drive, book a checkWhat does U0184 mean?
Infotainment modules share the network with the rest of the car because they play warning chimes, show settings, connect phone calls and, through the telematics unit, may call for help after a crash. When one goes silent, its feature stops and other modules store a code. A radio or telematics module that misbehaves can also stay awake longer than it should, which can drain the battery overnight.
What causes U0184?
- A radio or amplifier unplugged or loose after an aftermarket install
- A blown fuse for the audio system
- A failing telematics unit or its backup battery
- A module that does not go to sleep, keeping the network awake and flattening the battery
- Corrosion at an amplifier mounted in the trunk or under a seat
What to check first for U0184
- Ask whether any audio, phone or dash camera equipment was fitted recently
- Check the fuses for the audio and telematics modules
- If the battery goes flat overnight, have the parasitic drain measured
- Check whether the emergency call still works, on cars that have one
Can you drive with U0184?
You can drive safely. If the telematics module is the silent one, automatic emergency calling after a crash may not work, so have it checked, and get a battery that goes flat overnight looked at before it leaves you stranded.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.

These are the generic meanings every manufacturer shares. Each brand adds its own detail, so your car's handbook, its service information and a qualified mechanic have the last word. OdoKeep has no connection with any manufacturer, and the app does not read codes from the car.
