You may notice that there are two soot level readings in GDS2. Aug 11, 2017 · Regen can be restricted for many reasons. Yes, OTR Diagnostics will allow you to start a forced DPF regen no matter what the soot level is. If the DPF soot level is too high, the engine computer program will not allow the system to regenerate. Regards - Mike. This screen will also show the status of the DPF Regeneration switch. You will know a regeneration is taking place when the soot levels start to drop and the exhaust gas temp should rise a lot . High soot level means a plugged DPF or regen required. the values are perfect J. The thing is every time I run a scan the soot levels in grams is different, for example. As diesel exhaust passes through the filter, soot particles The Cat® Regeneration System (CRS) periodically introduces a small amount of fuel into the DPF to burn off soot. automatic regenerations of the DPF are halted by the ECU if the soot volume goes beyond a specific limit (which is measured in volume, not grams), regardless of the ash load. kw xy aa jo rt qt py of lb ca
