U0184 on Jaguar
Lost Communication With Radio
U0184 on Jaguar vehicles indicates lost communication with radio. Au7o has documented this code across 1 Jaguar model — most commonly on XJ. 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 Jaguar by Model
Jaguar XJ(1 issue)
- InControl Touch Pro Infotainment Freezing, Black Screen and Spontaneous Reboots (2016-2019 X351 Facelift)2016-2019
The 2016 facelift replaced the original X351 head unit with InControl Touch Pro (10.2-inch screen). Owners report the screen going black or freezing, the unit rebooting mid-journey, loss of navigation, phone and audio, and the on-screen climate/seat controls becoming unresponsive. JLR issued a string of software updates (Jaguar technical bulletin JTB00593 series for 'InControl Touch Pro features not functioning as expected') and a US class action was filed over Touch Pro/Touch Pro Duo behaviour in 2018-2020 models; owner threads document repeated dealer updates that only partially fixed the problem. The earlier 2010-2015 cars use a different (Bosch) head unit with its own freezing complaints, so the two should not be merged.
