12" screen upgrade on 2020 3500 Tradesman diesel, now all sorts of warning lights & service messages - any ideas?

[johninman]

I just installed a 12" UConnect screen in my 2020 3500 Tradesman Diesel to replace the dinky 5". The screen, sound, climate works great and its a very nice upgrade. However, once installed - I am now getting ABS warning light, brake warning light and traction control warning lights on dash. In addition to the lights, also seeing service messages to service ABS, service Trailer control & service stability control. My new screen does have the traction control button next to hazard switch at the top - made sure it had it before I purchased. Not sure what's going on but am about to take it to the dealer. Clearing the ABS codes via OBDII code scanner & they just come back. Checked all fuses. Any pointers appreciated.
