About Our Diagnostics for Trucks & Fleets

At Iron Buffalo Truck & Trailer, we specialize in finding solutions for complex, hard-to-diagnose problems. Your vehicle has several systems to alert you to issues, but there are a few warning signs that you should look for, and if found, address immediately:

  • Your engine fails to start.
  • Your battery is damaged, bloated, or dies.
  • Your headlights or brake lights are dull or dim.
  • You notice the smell of burnt plastic or wiring.
  • You see cracked, worn, or discoloured wiring.

Diagnosing and fixing electrical issues can be tricky, but our engine diagnostics experts recognize that it is vital to diagnose and repair electrical problems quickly and efficiently. We are committed to saving you time and money and understand that every day your truck is not available, you are not benefiting from the revenue generated by your vehicle.

Check Engine Light Issues

One of the first signs of an issue with your truck is typically a check engine light. The cause of a check engine light can be something as simple as a loose or faulty gas cap or a more severe issue such as a bad catalytic converter. While the check engine light may come on for various reasons, it is an indication that your vehicle has a problem that needs immediate attention.

Whatever the cause, it's best not to take the chance of causing significant damage. Our technicians have the training, skill, and advanced equipment to determine the problem quickly. Our team has seen, diagnosed, and repaired just about anything that can go wrong with any type of truck engine.

Additionally, we have the necessary software to adjust parameters in all engines. If you have an engine light on, or your truck just doesn't seem to be running the way it should, let us conduct a diagnostic test to determine the problem. Diagnostics can reveal issues in your truck's engine, transmission, exhaust system, brakes, and other major components, and our mechanics can also improve the performance of your truck.

Truck Diagnostics FAQs

What is truck diagnostics?
Truck diagnostics refer to the process of using specialized tools and software to identify, analyze, and troubleshoot issues within the electronic systems of commercial trucks. These systems encompass various components such as the engine, transmission, brakes, fuel system, and emissions controls.

Why are truck diagnostics important for vehicle maintenance?
They play a crucial role in proactive vehicle maintenance by allowing early detection of potential problems before they escalate into costly repairs or breakdowns. Regular diagnostics help ensure optimal performance, reliability, and safety of commercial trucks, minimizing downtime and maximizing efficiency.

What types of issues can truck diagnostics identify?
can identify a wide range of issues, including engine malfunctions, transmission problems, fuel system faults, electrical system failures, emissions-related issues, brake system abnormalities, and sensor or component failures. By pinpointing these issues early, diagnostics facilitate timely repairs and maintenance interventions.

How do truck diagnostics work?
Truck diagnostics involve connecting diagnostic tools or software to the onboard diagnostic (OBD) system of the vehicle. These tools communicate with the vehicle's electronic control units (ECUs) to retrieve diagnostic trouble codes (DTCs) and real-time data. Technicians analyze this information to diagnose issues accurately and efficiently.

I drive hot shot and had a situation where all my clearance lights went out. I called early in the morning and they got me in same day and had the problem fixed next day. It was a completely unreasonable ask as it was an electrical issue that I needed done in a 2 day window, not to mention they were slammed. These guys went above and beyond for me without a fuss and communicated every step of the way.  I HIGHLY recommend them to anyone. Thank you guys for all your help!

Absolutely the best customer service. I went in seeking a hard to find item that I did not want to have to wait for from amazon. To my surprise they had what I needed and made my day that much easier for my trailer repair.

We are so thankful that our motorhome was towed to JE-CO. After a very disappointing breakdown, JE-CO has been so accommodating and helpful. They have easy access, long business hours and have worked well with Ford and Tiffin to try to get our rig repaired . We would highly recommend them.Also, thank you G for keeping us informed on what’s going on.
