Problem with my F6 dp-tuner switch. Truck wont start now
 

So i got new programes a few months ago and just today decided to reset my switch.

I started the process which takes 5 times to do, and after the 2nd time the switch went blank and now shows nothing. When i turn on the ignition it shows the period and then is blank. The truck turns over but does not start.

What did i do wrong. I gotta have this truck.

Did you ever figure this out? Mine is blank suddenly tonight too, no start..

It is likely in No-Start. Turn the key to the On position then press and hold the left (-) button for 3 seconds. It should cycle back to 1.
