Hello, gentlemen. Because of this in my autku is dpf filter I wanted to ask if any of the forum users know if there is any hidden filter firing indication in Honda ?? There is a DPF control on the board but it lights up when the filter is already dirty. Being in the workshop when firing the filter in the service mode, I heard that some cars have a hidden firing signal, eg by turning on the mirror heating (regardless of weather conditions). Some magicians supposedly do signaling on the diode and it is known when the firing procedure follows, because without this it is a lottery. Can anyone cope with anything?
