Service function guideDPF Forced Regeneration

This guide delivers a complete, professional procedure for performing a forced regeneration of a diesel particulate filter (DPF) using a scan tool or OEM software, written for working mechanics and experienced DIYers who already understand diesel aftertreatment fundamentals. It explains how the DPF captures soot and how regeneration burns it off, then walks through when a forced regeneration is justified, how to prepare the vehicle and workshop, and the full step-by-step execution from connecting a battery maintainer to confirming a successful burn. Readers will learn to interpret differential pressure and soot mass readings, adapt the procedure across light, medium, and heavy-duty platforms, avoid the mistakes that destroy filters or overheat exhaust systems, and troubleshoot failed regenerations with a logical diagnostic sequence. After finishing, a technician will be able to run a controlled forced regeneration safely, verify its result with measurable data, and apply correct aftercare so the filter and engine return to normal service.
