Tech Tip: How to clean DPF with manual regeneration mode on scan tools
June 4, 2013
As part of a periodic maintenance for DPF equipped diesel vehicles a manual or automatic regeneration is needed.
The Autel all-in-one MaxiCheck Pro performs all of the functions of the other MaxiCheck tools combined.
Many diesel vehicles today come equipped with a Diesel Particulate Filter (DPF). These filters are mandated by federal emission regulations to reduce particulate matter built up by diesel engine exhaust gas. Therefore, it is very important to inform your customers on the importance of periodic cleaning of the DPF. As part of a periodic maintenance for the DPF-equipped diesel vehicles, a manual or automatic regeneration is needed. This is very important because if left alone, it can cause not only a filter replacement which is costly to repair, but also a "check engine" light to illuminate with a reduced engine power message or other message relating to the DPF.
To clean a DPF using manual regeneration mode, you can use a specific service tool like the MaxiCheck Pro from Autel or other service tools for diesel engines. Just attach the tool to the DLC and access the module's function to clean the DPF. Some tools will have a built-in step-by-step process, or just a simple "yes" or "no" function. However you handle it, make sure to always look up the information about the DPF regeneration mode in the vehicle's service manual before you start.
