Folks on Turbo Diesel Register forum have tried to help with this, but no experience with it so far.
2018 Ram 3500 Cummins Aisin with 8.4 inch UConnect. For a few months have had intermittent, simultaneous failure of both the radio screen and the central digital EVIC screen between speedo and tach. The analog-looking gauges like those, temp, oil pressure, etc remain normal while central EVIC and radio are blacked out, blank. Function will return while still driving. Have not observed how the screen resumes for either, so far, just notice they are both “back” at the same time.
Our dealer, ****’s CDJR in Wilsonville OR has been conscientious and helpful, the service manager and his shop foreman working together the past week trying to replicate this, but without success so far.
They asked me to leave the Edge Insight disconnected so the OBD port has nothing connected to it, because sometimes having any device connected to the OBD port causes some kind of communication problem within the truck’s electronics. They want to eliminate that as a possible factor while we are trying to diagnose this.
Update after taking home:
Our dealer kept truck two weeks, driving it, and problem did not occur. They asked me to leave the Edge Insight disconnected from the diagnostic port, saying sometimes having anything connected there interfered with communication among components (on the CAN bus, or ???). I drove an hour home today and it did not occur (no Edge Insight connected).
This raises a new question, has anyone had or heard of the experience of having their Edge Insight or other Edge product produce radio and/or EVIC "blackouts"?
I'll drive w/o Edge for some time; if it does not have the problem, I'll reconnect the Edge and see what happens. I'm vidoetaping the dash now with my iPhone on a mount attached to a passenger seat headrest post while driving, hoping to catch it as it happens and when it comes back on video.
Hoping those on this electronics subforum will have some experience that bears on this puzzle.
Thanks
