U0001 Hi Speed CAN Bus

[Mtinsman]

Heu guys,

I have a 2013 ram 3500 SRW with 92000 miles on it. Its fully deleted and running the Raceme Ultra. I keep getting a code U0001 High Speed CAN Bus lost connection. I have cleared that code at least a hundred times. This last time it popped up the dash lights went crazy. Im at a lose. I am debating on taking it to the dealer ship but being fully deleted Im sure they will complain about that and give me a run around.

Any help is greatly appreciated.

Thanks.

Who tuned the truck bud? Might be something with the tune. Sometimes they can be finicky as low voltage on your batteries LOL.

LOL!! It was a box tune I got from Rudys Performance. I put it in a little ovet a year ago. Im gonna try changing the batteries out. I replaced them last year but I got them from Battery Mart. They are a wholesale battery shop Im sure I got junk batteries.
