Computer Diagnostics & Forced DPF Regeneration USA & Canada | 24/7 Roadside Support
It starts with a single amber light on the dashboard — the dreaded DPF icon. Then comes the warning: Exhaust Filter Full. Service Required. If you are lucky, you have time to find a place to pull over. If not, your truck’s ECM makes the decision for you, cutting horsepower and initiating a derate.
In the modern era of Tier 4 emissions and complex aftertreatment systems, a software glitch or clogged filter can ground your truck just like a broken axle. At MTS Truck Repair, we specialize in mobile computer diagnostics and forced DPF regeneration across the United States and Canada.
We bring diagnostic power and emissions troubleshooting directly to your location, whether you are on the shoulder of a U.S. interstate, at a truck stop, or on a Canadian freight route.
Are you currently in derate? Is your Stop Engine light flashing? Call MTS Truck Repair right now at 1-844-888-7587.
24/7 Emergency Computer Diagnostics & Emissions Support
Emissions systems are sensitive to idle time, fuel quality, temperature, sensor failures, and exhaust restrictions. A NOx sensor can fail in freezing weather. A DEF pump can fail in summer heat. A clogged DPF can turn a normal delivery into a shutdown event.
MTS Truck Repair operates 24 hours a day, 7 days a week, 365 days a year. When you call, we ask for your symptoms, warning lights, engine make, and available SPN/FMI fault codes so the right diagnostic support can be dispatched.
The 5-MPH derate is a ticking clock. Call 1-844-888-7587 now for emergency assistance.
What We Fix: Diagnostics & Aftertreatment Solutions
We do more than read codes. A basic scanner may tell you a fault exists, but proper diagnostics identify why the fault exists. Our technicians troubleshoot the aftertreatment system, emissions sensors, DEF system, ECM data, and related engine conditions.

Why Choose MTS Truck Repair for Diagnostics?
Avoid the Dealer Trap
Dealer diagnostic delays can cost days of downtime. Mobile diagnostics help identify the problem where the truck sits, often saving towing, hotels, missed loads, and wasted waiting time.
Professional Diagnostic Tools
Modern trucks require proper diagnostic software and interfaces. We support major engine platforms including Cummins, Detroit, PACCAR, Volvo, Mack, and Allison-related systems.
Technician vs. Parts Changer
A derate does not always mean the DPF must be replaced. Sometimes the real issue is a sensor, wire, DEF problem, doser valve, or airflow issue. We focus on root-cause troubleshooting.
