Description - ENGINE COOLING - Fiat ULYSSE 2.2 16V JTD fino a 04/03
The cooling system for the engine radiator and air conditioning condenser consists of two fans operated at different speeds by means of a connection between them either in series or parallel.
Operational Description - ENGINE COOLING - Fiat ULYSSE 2.2 16V JTD fino a 04/03
Engine control unit M010 controls the operation of the engine cooling fan according to data supplied by linear sensor K120 and engine coolant sensor K036. Both sensors are connected directly to the engine control unit; K036 to pins E1, D1 connector B, while K120 is connected to pins H4, H2 and F2 of connector A.Control unit M010 operates fans N011 and N012 on the basis of data supplied by both sensors.Operation at first speed: fans in series:The engine management control unit energizes relay J030, pin 2 from pin D4 connector A; the relay coil is supplied by the engine compartment junction unit B001, from pin 14 connector C, by the line protected by fuse F08 and operated by a specific relay.When the relay is energized, it supplies the fans N012 and N011, connected in series, through the line coming from junction unit B001, pin 6 connector G protected by fuse MF6 (relay J031 is not energized and connects the two fans in this way).Operation at second speed: fans in parallel:The engine management control unit energizes relays J030 and J032, pin 2 from pin B2 connector A; the relay coil is supplied by the engine compartment junction unit B001, from pin 10 connector C, by the line protected by fuse F01.When the relay J032 is energized, it supplies the fans N012 and N011, connected in parallel, through the line coming from junction unit B001, pin 1 connector G protected by fuse MF1 (relay J031 is energized and connects the two fans in this way).
