The engine management control unit M10 controls and manages the DPF system with the help of 3 special sensors:- downstream particle filter temperature sensor K190;- upstream particle filter temperature sensor K189;- DPF differential pressure sensor K187.Sensor K190 receives an earth signal from the engine management control unit M10 - pin 33 of connector A - and sends the temperature signal to pin 32 of connector A of M10.Sensor K189 receives an earth signal from the engine management control unit M10 - pin 35 of connector A - and sends the temperature signal to pin 34 of connector A of M10.Sensor K187 receives a power supply and an earth signal from the engine management control unit M10 - pin 44 and 37 of connector A - and sends the pressure signal to pin 36 of connector A of M10.The control unit M10 sends, via the C-CAN - pins 83 and 84 of connector A, the signals useful for the display of the warnings lights and messages in the instrument panel E50. The latter, via the C-CAN/B-CAN communication gateway management by the Body Computer M01, communicates with the system - pins 8 and 9 of connector A - managing the signalling for the management of the filter regeneration process ("particle filter blocked") or by signalling the impossibility of the filter regeneration ("EOBD failure").
