Dealer claimed they had a fix, without replacing it. Skeptical. I haven't done my first service yet, so I'll give them one chance. The again, maybe it is some weird grounding issue or something like that.

Yup. Mine too on the drivers side... on my Trail Boss about a month after I got it.

Thanks Josef! Very helpful. I have a 10-speed tranny, so it looks like I have DFM. (not sure if that is a blessing or a curse at this point)

No items that require a pulse of power to start, like a circular saw or refrigerator. Seems like Contractors would be the perfect market for this, but alas. Seems like it might only be useful for lights. I see someone mentioned a TV or satellite dish for tailgating.

Sorry to be a dumbass, but where do I find my RPO Codes? I am looking the window sticker and I don't find any mention or credit listed. (Bought it new BTW.)

Just bought a new Trail Boss LT. Yup. All selling over MSRP. Finally found a dealer to get it down to $2500 over. Best I could do. I'm in Southern California.

How can I tell if my Silverado Trail Boss has the DFM/AFM chip/module installed and functioning?
