Has anyone had this problem?The sensor bell goes off but nothing shows up as wrong. Than all the dash board warning images start flashing, the screen goes black for a second than comes back on and only the check engine light stays on. It doesn’t effect the performance of the truck? We’ve had it at Chrystefer Doged for almost a week now and they don’t seem to know what’s wrong? The codes it pulls is lost communication. Sooo fustrated.

I suspect the TIPM, just on principle. [https://www.knowyourparts.com/technical-resources/electrical/late-model-chrysler-tipm-diagnostics/](https://www.knowyourparts.com/technical-resources/electrical/late-model-chrysler-tipm-diagnostics/)

Either that, or the alternator is failing.

I think the answer to this issue is with one of the previous posters ideas. All are good potential areas to cause the trouble. I would check the alternator for excessive AC ripple voltage and verify the power path to the dash panel to make sure that proper power is getting to it. You didn’t state how often the trouble happens. Tapping on suspected areas with a screwdriver may help show up the trouble area.
