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.Engine control unit M010 receives a signal from coolant temperature sensor K045 at pins 84 and 85 of connector B and a signal from linear sensor K120 at pin 75 of connector A.Control unit M010 enables activation of fan N011 from pin 20 of connector A. It also sends an engine coolant signal to Body Computer M001 (pins 32 and 33 of B) via the C-CAN network to pins 9 and 10 of conector A.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 1 and 3 of connector D), 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.
