Why Diagnostics First

Fix It Right the First Time

A modern heavy-duty truck is a network of electronic control modules, and a single fault code can park a truck. Our heavy-duty computer diagnostics go beyond reading the code — we pull live data, confirm the root cause and perform the right reset, calibration or component test.

When a truck derates, it's often the aftertreatment or DPF system calling a fault. We handle forced DPF regeneration, parked regen and DEF/SCR/NOx diagnostics on site, clearing the condition without a trip to the dealer.

Whether it's a Freightliner check-engine light or a Volvo aftertreatment derate, get a clear diagnosis and a fix — fast, and where your truck sits.
