I would always suggest to use a tool such as Cummins Insite or TEXA (you can even rent one from Diesel Laptops). The ECM activates the fault codes based on the measured pressure difference across the DPF. For many years, operators of commercial trucks have been trying to increase uptime and minimize unscheduled and costly roadside repair events. Engine problems: If the engine has malfunctioned, it is possible that excessive soot is created, causing the DPF to get blocked. What function does it perform inside the diesel emissions system?
