Computer Diagnostics & Regens

When the Lights Come On, We Get to Work

Modern diesel engines are smarter than ever—but when things go wrong, they don’t always tell you why. At KC 24 Hour Truck Repair, our computer diagnostics service is designed to get to the root of engine issues fast—before a small problem turns into a big breakdown.

From check engine lights to full-on de-rate conditions, we scan, diagnose, and solve issues using advanced technology and decades of diesel expertise.

🔍 We Diagnose & Fix Issues Like:

We diagnose, repair, and replace:

✔ De-rate mode triggers
✔ Active & inactive codes (check engine, fault lights, etc.)
✔ Diesel particulate filter (DPF) regeneration problems

✔ DEF (Diesel Exhaust Fluid) system faults
✔ DEF quality sensor failures
✔ ECM (Engine Control Module) malfunctions and resets
✔ Sensor and wiring issues
✔ SCR and EGR system diagnostics
✔ Turbo and boost pressure alerts

If your truck won’t regen, is burning excess DEF, or throwing cryptic ECM codes—we’ll find out why and recommend the fastest path to repair.
