Engine cooling fan N011 is supplied by an ignition-operated line (15/54) protected by fuse F16 of engine bay junction unit B001, and a battery-controlled line (+30) protected by fuse F6 of B001.The engine management control unit M010 receives a signal from engine coolant temperature sensor/sender unit K036 at pins 41 and 58 of connector B and signal from linear sensor K120 at pin 13 of connector A.The control unit M010 enables the engagement of the fan N011 from pin 90 of connector A.It also transmits the signal for the engine coolant temperature, from pins 61 and 62 of connector A, via the C-CAN, to the Body Computer M001 (pins 32 and 33 of connector B).Climate control unit M070 is supplied by ignition-operated lines(INT) protected by fuse F49 (pin 1 of connector A) and battery-controlled line F39 (pin 16 of connector D), both contained in underfacia junction unit B002.Infotelematic control unit M065 receives a signal from engine coolant level sensor K026 at pin 22 of connector D and sends it (from pins A1 and A3 of connector B), via the B-CAN network, to Body Computer M001 (pins 5 and 7 of connector H), which, in turn, sends it to instrument panel E050 (pins 3 and 4 of connector A) from pins 5 and 6 of connector E via the B-CAN network.
