I bought my edge used off my brother in law last weekend, got it home hooked up on level 2 all was well. Today I detailed my truck and had all four cab doors open for about and hour, I get in the truck tonight and start it up and the edge screen is illuminated, but shows nothing. I shut the truck down and it is still lit up, it won't shut off. I then unhooked the battery for about 30 seconds and reconnected, and the edge came on without the key on and prompted me to turn it on. When I did this it acted fine, but wouldn't let me set my tire size or shift firmness or any custom settings. It gave me an error F1. Any insight would be appreciated. Thanks!

 

update, i just came in from the truck and everything is up and running again, i think i answered my own question when i left the doors open today. i think that may have put just enough strain on the battery to give the edge trouble. it loaded up fine and is working normally now.

 

Yes, the Edge needs a fully charged battery. It will often give you a warning that your battery is getting weak.
