DRD SD Code Issue

[Pogo0430]

Hello,

I am running the M3M DRD tuner and I am wondering if there is a way to check emissions codes with it first off and second I keep having an SD card error 20002 when I try to go to the program button on the screen.

I’m not sure if this SD card is bad or just needs updates?

I am the second hand owner of this truck with this tuner.

The original owner was Andrew Larson.

Not sure if that would help.

20002 is a generic SD card fault.

You need to format and reload everything on the card.

There are several guides on the forum for how to do this correctly.

Or refer to MM3 website.
