CEL Code - Can The MM3 Tuner Pull The Code?

[Keron2233]

Hello, fellow Rammers; I got a check engine light, but the truck seems to be running fine.

I’m running an MM3 tuner, and I can’t remember how to pull up the CEL code on the MM3 tuner.

Can someone steer me in the right direction regarding how to do this?

Touch the MM3 screen while on the gauge screen and select the “Main Menu” icon, then select “ECM,” then select “DTCs.”

If you need help with the code, please let us know.

Keron2233 Any of you guys/girls have any suggestions; I’m gonna check the wiring plug and make sure it’s still snug.
