    Default 2007 Silverado 2500HD 6.6L LMM LTZ 4x4 - Display Trouble Codes?

    I have a check engine light and am curious if I can display the actual trouble code on the dash info system? If yes, how please?

    Thanks!

    Now, that's a great idea; however, to the best of my knowledge, GM hasn't thought about it. You need a scanner, plugged into the access port at the bottom of the dash.
