LAUNCH X431

 This article will describe how to use the LAUNCH X431 PAD V ELITE to perform the PDF parameter reset function (on a 2013 MAN TGM truck after replacing the PDF). Background description : The DPF (Diesel Particulate Filter) in a diesel engine is responsible for capturing carbon particulate matter in the exhaust and preventing it from being released into the atmosphere. Over time, the DPF can become clogged. Normally, performing DPF regeneration can clear the clogged particles, but if the blockage is severe, cleaning or replacement may be necessary. Even after replacing the DPF, the old carbon load data (i.e., the total amount of particulate matter accumulated in the DPF) stored in the vehicle’s ECU (Electronic Control Unit) still exists. If it is not reset, the ECU will mistakenly believe that the new filter is severely clogged, thus continuously triggering regeneration commands, limiting torque and speed, and even illuminating the malfunction indicator lamp, affectin...
