Remove it from the truck for 30 minutes and then retry. This usually works

I had one that took me week to get back. I tried it after 24 hours and nothing. Then I forgot about it for week and when I grabbed it off of the shelf a week later it was all good.

I've had the exact same thing happen to me. No communication, won't recover. Let it sit for several days, hook it up on the bench and viola! it recovers.

They were angry female units. They needed a few days to calm down.

Thanks for the reply's. We've checked the fuses and did the master reset, but still no luck. I think my efilive messed up cuz now the scaner won't work. I guess ill be sending it in to see whats wrong with it.
