Engine Diagnostics

Guesswork is expensive. We use dealer-level diagnostic equipment to pinpoint the true cause of check-engine lights, derates, and performance issues — the first time.

Electrical Diagnostics

Electrical faults are the hardest to chase — and where experience matters most. We specialize in tracing intermittent electrical problems, CAN bus faults and wiring issues to their source.

DPF / DEF / SCR Repair

Aftertreatment faults trigger derates that can strand your truck. We diagnose and repair DPF, DEF, SCR and EGR systems to clear faults and restore full power.

A dead battery or failed alternator can strand you anywhere. We diagnose and repair batteries, alternators and starters to eliminate no-starts and charging faults.

Air System Repairs

Your air system powers your brakes and suspension — a leak is a safety issue. We locate and repair air leaks, compressors, dryers and valves quickly.

Engine Programming

Modern diesels are as much software as hardware. We handle engine programming, calibration and parameter updates to keep your truck running as the manufacturer intended.

ECU Programming

Replacing or reflashing a control unit requires precision. We program and configure ECUs so new or updated modules communicate correctly with the rest of the vehicle.

ECM Diagnostics

The ECM is the brain of your engine. We read, interpret and act on ECM data to diagnose complex faults that basic code readers can't uncover.
