Truck Diagnostics Services in Charlotte, NC
Diagnostics that find the fault before anyone orders a part — dashboard warnings, electrical faults, emissions and driveability, measured rather than guessed at.
Detail
Diagnostic services
We diagnose across the systems, not just the one with the light on:
- Transmission diagnostics
- ABS brake system diagnostics
- Electrical system troubleshooting
- Diesel particulate filter (DPF) diagnostics
- Suspension diagnostics
- Emission system diagnostics
- Dashboard warning lights
Why bring it here
A diagnostic is worth what its conclusion is worth. Reading a code and replacing the part it names is how a truck comes back twice for the same fault. Our technicians work from the measurement out — voltage under load, pressure at the port, the circuit rather than the component — so the repair that follows is the repair the truck needed, done once.

FAQ
Common questions
What are truck diagnostics, and why are they important?
Truck diagnostics involve using specialized tools to pinpoint issues within a vehicle’s systems, such as the engine, transmission or electrical components. Diagnostics identify the exact problem, so the repair is targeted rather than a sequence of replaced parts.
How often should I get a diagnostic check for my truck?
Schedule a diagnostic check whenever a warning light comes on, or when you notice unusual performance such as reduced fuel efficiency or strange noises. Routine diagnostics during preventive maintenance also catch small issues before they become bigger problems.

In addition to Charlotte, NC, many of our customers come from all over North Carolina, including Shelby, Salisbury, Statesville, Hickory, Concord, Kannapolis, Mooresville and Matthews.

I personally think this is the best most knowledgeable shop great tire guys great mechanics. Very safety conscious! When you leave here all questions are answered and you’ll feel better about your ride. So if your coming through Charlotte stop in and check them out.
Arlen Ledbetter Professional, knowledgeable and reasonable on pricing. I’ve had alignments and balancing done here as well as an oil change. As an owner operator, I find Reed and the staff some of the best around in Charlotte when it comes to maintaining a semi.
Clever Black EagleSpan installed 6 new tires on my RV. They got the tires I wanted quickly, balanced and mounted the tires while I waited. They even installed new valve stems. Friendly people, great prices and speedy service earns them 5 stars. It’s also the only place in the Charlotte area that I know of that does alignments on big rigs.
