michbl1 Posted February 10 Report Share Posted February 10 (edited) Hello, Today I noticed that after locking the car, the dashboard clocks turn on and off on their own, then turn on again for a few seconds and then turn off again... what could be the reason ? remote key is far from the vehicle and the situation is continues Thanks in advance.

5rebel9 Posted February 10 Report Share Posted February 10 Is radio and remote locks all factory original or has the vehicle been "modified"? I had a problem similar that dash lights/ driver info screen and 4.3 infotainment screen would shut off as normal and then turn back on and stay on. It turned out to be a defective radio module. To give a general location Idea , it's where the CD slot is. The center trim and components would need to be removed to gain access to it, but not a hard job.

michbl1 Posted February 10 Author Report Share Posted February 10 One year ago I've changed main radio box from 8.4 Uconnect without navi to 8.4 Uconnect with navi. Till today everything was working properly. Quote Link to comment Share on other sites More sharing options...
5rebel9 Posted February 10 Report Share Posted February 10 Hard to say what caused this to happen then. If it only did this one time, I will STRETCH FAR and GUESS that maybe a front door handle was still sensing by passive entry, or a door or handle was not fully closed. Keep an eye on it when you shut down the car and go to leave the vehicle that it happens again or not. good luck! Quote Link to comment Share on other sites More sharing options...
michbl1 Posted February 10 Author Report Share Posted February 10 It is continues doors are lock dashboard on/off/of/off... after entry to the vehicle the same, after engine start and stop and ignition on OFF position even radio is on... No I've disconnected negative cable from ACU to not to "kill" ACU. Quote Link to comment Share on other sites More sharing options...
michbl1 Posted February 15 Author Report Share Posted February 15 After diagnose via computer, mechanic saw that there was temporary problem between communication with radio hub (the one which I've replaced one year ago). Do I need to update new radio box (Uconnect) in vehicle computer ? After replacement I've only changed HVAC settings for all sections of AC Quote Link to comment Share on other sites More sharing options...
John/Horace Posted February 18 Report Share Posted February 18 There are software updates available for the 8.4. I’ve never been brave enough to try it. https://www.driveuconnect.com/support/software-update.html A year is a long time for something to pop up. May have to swap back original no nav screen temporarily. Lots of issues with driver door harness wires breaking and causing strange issues.

michbl1 Posted February 19 Author Report Share Posted February 19 Some years ago I've updated UC 8.4 via USB with software downloaded from their site, but it was done with old 8.4 without NAV. That time i didn't sam any differences. Quote Link to comment Share on other sites More sharing options...
