Frequently Asked Questions
What does a truck computer diagnostic include?
We connect professional diagnostic software to your truck's ECM and ECU, read active and stored fault codes, interpret the data, and pinpoint the root cause before any repair begins.
My check-engine light is on. What should I do?
A check-engine or warning light means the system has logged a fault. Bring the truck in or call 717-865-2388 so we can read the codes and tell you whether it is safe to keep driving.
Which truck and engine brands can you scan?
We diagnose Cummins, Caterpillar, Detroit, PACCAR, Volvo, Mack, and International systems, covering engine, transmission, ABS, and aftertreatment modules.
Can you clear fault codes after the repair?
Yes. Once the underlying problem is fixed, we clear the codes and verify the repair so the warning light does not return for the same issue.
Do you diagnose DPF, DEF, and aftertreatment faults?
Yes. We diagnose emissions and aftertreatment codes, perform forced regens, and identify failing DPF, DEF, EGR, and sensor components.
Do you offer mobile diagnostics on the road?
Yes. Our mobile units can scan and diagnose many faults on-site 24/7 along I-81, I-78, I-76, I-83, and nearby routes in Central PA. Call 717-865-2388.
How much does a diagnostic cost?
Diagnostic time is billed at our standard labor rate. Call 717-865-2388 for current pricing and to schedule a diagnostic for your truck.
What payment methods do you accept?
We accept EFS, T-Chek, ComData, WEX, Fleet One, all major credit cards, and cash.
