Every diesel truck has a story—and it’s written deep inside its control systems, from how your turbo’s behaving under pressure to what your DPF sensors are seeing mile after mile; that data matters. Diesel Highway INC. makes sense of it all with Truck Computer Diagnostic Services in Detroit MI, designed to keep you running strong and avoid those costly shutdowns.
Your truck’s brain, better known as the ECM, is always working. With the right tools and a sharp understanding of its language, we dig into the small warning signs that most folks miss. If you’re hauling freight around Detroit, there’s no time for guessing games. You need straight answers and fast fixes.
We use dealer-grade diagnostic tools to run full checks on:
When you’re moving heavy loads through Michigan’s roads, even the smallest glitch can throw off your whole route. Our diagnostics don’t just chase fault codes—they reveal what’s really going wrong behind the scenes. Whether it’s an uneven fuel-air mix or a sensor throwing off readings, we pinpoint the real issue and cut the delay short.
The biggest benefits of trusting our process:
We also take the time to explain everything clearly. Whether it’s an EGR valve failure or an issue with NOx sensors, we break it down so you fully understand what’s happening—and why it matters for your next haul.
Running loads through Detroit’s tight turns and long miles is no small job. You need gear that holds up and support that actually helps. That’s where Diesel Highway INC. stands out—with its truck computer diagnostic services in Detroit MI, that are all about keeping working rigs like yours road-ready and rolling strong.
We don’t throw jargon or scare tactics. We read the codes, spot the issue, and guide you on what’s next without wasting your time. Because when your truck speaks, we know how to listen—and we know what to do with the info. With each scan, we help you stay ahead of trouble and closer to the road where you belong.
Starting problems don’t always come from the truck’s starter. Our diagnostics go into cold crank data, fuel system feedback, and ECM history to trace the real cause of delayed starts—saving you time and cold morning stress.
Too many forced regens slow your day down. We scan your after-treatment data closely to spot faulty regen commands, blocked sensors, or damaged DPFs that trigger unnecessary cycles—and help get your emissions system back on track.
Some problems come and go without warning. Our deep-dive diagnostic tools record live sensor behavior, helping us spot intermittent issues that others often miss. No more driving around with a mystery problem that won’t stay still.
Yes. Low voltage can give false codes or stop the computer from responding. We check power first to avoid that.
Every 3–6 months is smart. It can catch small problems early—before lights come on or things get worse.
Some problems don’t set off codes. We check live data and sensors to track down those hidden issues.
