Recently bought an edge CS for my 02 f150. Today it won't turn on, just beeps. I've checked the fuse for the OBD II port and thats ok. I have a tune loaded and I was wondering if updating the firmware on the tuner would affect anything on the truck, or if it would even help?

 

Get your battery load tested. The Edge requires a strong battery and it could be warning you of a failing battery.

battery needs to be checked

 

are you sure the fuse is good.....did you meter it....

 

Everything was good, updated the firmware on the programmer and it's now working.
