FAQ

Diesel Diagnostics questions.

Can you read my fault codes on-site?

Yes. We bring the diagnostic equipment to you, pull the codes, and test the circuits to find the real cause - not just the symptom.

My truck went into derate - can you fix it?

Often, yes. Derate is usually an emissions or sensor fault. We diagnose the cause - DEF, DPF, SCR or a sensor - and repair it so you are back to full power.

Do you diagnose electrical problems?

We do. No-starts, charging faults, parasitic draws and wiring gremlins are some of our most common diagnostic jobs.

What does diagnosis cost?

Call (678) 372-2667 and we will explain how we charge before we start. You get an upfront price and a straight answer on what is wrong.
