Modern heavy-duty diesel trucks are rolling computers. Today's semi trucks are equipped with sophisticated engine management systems, emissions controls, transmission electronics, ABS, and a web of sensors and modules that all communicate constantly to keep the truck running at peak performance. When something goes wrong, guesswork isn't good enough, you need precise diagnostics from technicians who know diesel. At Rolling Smoke Diesel Repair, we offer comprehensive diagnostic services built specifically for heavy-duty commercial trucks, so we can find the problem fast and get you back on the road.
Our Diagnostic Services
- Check Engine and Warning Light Diagnosis: A check engine light, emissions fault, or any other warning indicator on your dash can point to dozens of potential issues. Our diagnostic equipment interfaces directly with your truck's ECM to pull fault codes and live data, identifying the root cause rather than just clearing the light and hoping for the best.
- Engine Performance Diagnostics: If your truck is down on power, running rough, smoking excessively, struggling to maintain speed under load, or burning more fuel than it should, our diagnostics can isolate the cause, whether it's an injector issue, turbo problem, EGR fault, or something deeper in the fuel or air system.
- Emissions System Diagnostics: DEF systems, DPF regeneration issues, EGR faults, and SCR malfunctions are among the most common reasons a modern diesel truck gets derated or throws a fault. We have the tools and experience to diagnose and repair emissions-related issues without unnecessary parts replacement.
- Electrical System Diagnostics: From faulty wiring harnesses and bad grounds to malfunctioning sensors and module communication failures, electrical gremlins on a heavy-duty truck can be difficult to track down without the right equipment. Our technicians know how to navigate the complexity of modern truck electrical systems and find the actual source of the problem.
- Brake System Diagnostics: ABS faults, air system issues, brake imbalance, and electronic brake controller problems all require proper diagnostic equipment to identify accurately. We'll pull the fault data and physically inspect the system to give you a complete picture.
- Transmission Diagnostics: Whether you're dealing with an automated manual transmission throwing fault codes, slipping gears, hard shifts, or a manual trans with unexplained noise or behavior, our diagnostics help isolate the issue before any teardown begins, saving time and money.

Schedule Your Diagnostic Service
When your truck is throwing codes, displaying warning lights, or just not performing the way it should, don't ignore it and don't guess. A small fault can cascade into a major breakdown, or worse, a roadside DEF derate that leaves you sitting at 5 mph on the interstate with a full load.
Bring it to Rolling Smoke Diesel Repair. Our team is ready to dig in, find the problem, and give you a clear path to getting it resolved. Contact us to schedule your diagnostic service today.
