@Bfazona Thanks for the info got my speedometer reprogrammed.

 

In Forscan on the menu down the left side, the button with the wrench icon is about half way down.

 

Glad I could help out. That PCM relearn is a simple step, but required for the 2018+ trucks to avoid the light.

 

I actually didn't do the PCM relearn. When I googled how to relearn the PCM it was much more involved than doing it through forscan. Wanted to make sure I had it set correctly before I did the relearn, but it didn't throw a code.

 

Yeah, googling the PCM relearn will give you methods that do not involve Forscan. The Forscan method is quite easy and you can double check afterwards to see if you have a DTC present following the relearn process.
