Mm3 tuner making gauges go crazy.

[Odp]

Ive looked around the web and didn't find much related to mm3 tuner issues other than that low battery voltage could and sometime will cause issues with the mm3. My batteries are 2 months old now. My 2016 just started going crazy with mm3 plugged in. Just driving my tps light would come on and start dinging. My gauges would start flashing on and off and several of the illuminated lights for things like tow haul ect would just start comming on and off. The tps light was most annoying since it stayed on and dinged. I previously had new tires installed and used the funtion in the mm3 to reset the tire pressure for my new tires since it was different. Didnt have any problems until now. I pulled over to see if i went back in and changed it agian and updated it if the light would go off. No change. So thats when i unplugged the mm3 from the obd port thinking i would reset it and try agian. Once i unplugged it the light went out. I drove the truck all this week with it unplugged. Have not had any issues. Plugged it back in and it started to glitch up my stuff agian. Has anyone else had any issues like this ? Just started suddenly. Its been a great system up until this. Thanks in advance.

I would reach out to double r diesel and see what he says since your using the mm3.

I can't talk from experience so just offering my advice.
