When to bring it in
- Check-engine or aftertreatment lights that return
- Derate, limp mode, or loss of power on grades
- Hard starts, no-starts, or intermittent cutouts
- Warning lights with no clear cause
A truck that loses power, throws a light, or cuts out under load needs more than a code read. We connect to the engine, aftertreatment, transmission, and chassis modules, then verify the complaint on the bay or on a road test when the symptom only shows up rolling.
