Why North Dakota customers mail in duramax lb7 / lly ficm repair

North Dakota has roughly 0.9 million registered vehicles, and full-size pickups & 4x4 SUVs make up much of what Fargo-area shops and owners mail us. Domestic work like duramax lb7 / lly ficm repair runs high-volume across North Dakota — we see a steady stream out of Fargo, Bismarck, Grand Forks. Cross-country far-north — about 3 days each way.

What we see from the Midwest

Salted winters plus long agricultural and towing duty cycles are the pattern we see from the Midwest. Modules on these trucks accumulate an unusual number of thermal cycles — cold soak overnight, hot underhood by mid-morning — and that is the loading that eventually opens a marginal solder joint. It is also why an intermittent fault that follows temperature is worth mentioning on your job note.

Do you accept duramax lb7 / lly ficm repair modules from North Dakota?

Is there a duramax lb7 / lly ficm repair shop in Fargo I should use instead?
Most Fargo shops don't keep the bench equipment for duramax lb7 / lly ficm repair — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-country far-north — about 3 days each way.
Does North Dakota vehicle inspection or emissions testing affect this service?
North Dakota has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all North Dakota and federal requirements.
Can a shop send these in on behalf of a customer?
Yes, and a good share of our diesel work comes from shops. Ship it with the shop as the return address, put the job number on the note, and we will text updates to whichever number you give us. The diagnostic notes from a shop are usually better than what we get direct, which makes the bench work faster.
Where does the work actually happen?
At our own bench in Arlington, Texas. Auto Module Lab is a mail-in electronics lab — we do not have branches in other cities and we do not sub the work out. Modules come to Arlington from all fifty states and go back out from here.
