Description - ENGINE COOLING - Fiat DUCATO 2.0 16V fino a 02/05
The engine control unit consists of a fan operated by the engine management unit in accordance with parameters supplied by the coolant sensor. Both fans operate at low speed, supplied via a resistance load that limits the current, and at high speed, governed by a dedicated relay located in the engine bay junction unit.The entire engine cooling system is protected by dedicated fuses housed in the engine bay junction unit.
Operational Description - ENGINE COOLING - Fiat DUCATO 2.0 16V fino a 02/05
Control unit M010 receives engine coolant data, measured by dedicated sensor K036, via pins E4 and D4 of connector B.On the basis of input data and stored parameters, engine management unit M010 determines whether to activate the high or low speed setting of engine cooling fans N011 and N012.The control unit controls the low speed of both engine fans N011 and N012 from pin K4 of connector A.The unit supplies an earth signal to supply relay coil T06. The power supply reaches the fans via resistance load O010, which reduces the current.Engine management unit M010 controls the low speed of both engine fans N011 and N012 from pin J4 of connector A. It supplies an earth signal to excite the coil of relay T078 and a direct power supply from the battery is supplied to the fans.The high and low speed supply lines are protected respectively by F07 and F06 housed in engine bay junction unit B001.
