Ok, so when I turn the truck to the run position the tuner comes on just fine, but when I start it from there it shuts off and won’t come back on until I turn the truck off and unplug and replug it in the OBDII port.
Any ideas?
TIA.

Truck batteries?
Mine does that and/or the tunes won’t load automatically.
Taking my truck Friday to get two new batteries.
One of mine is showing weak even after a full charge on each one.

Maybe?
I’ll have to have them tested.
Mine started to do the same thing.
Batteries are 4 years old.
Time for new, I think.

New batteries last weekend.
It seems to have taken care of the MM3 turning off and staying off. (Turning off and flashing red/green on the side).
Also, a buddy of mine had the same issue on his Chevy, and replacing the batteries took care of it as well.
