The supply for the fan N11 arrives directly from the battery via relay R6 housed in the engine compartment junction unit B01 from the line entering at pin 1 connector A of the actual unit.This supply line is protected by fuse F6 housed in the junction unit B01 .The relay R6 is enerigzed by an earth signal coming from the engine management control unit M10 . The engine temperature sensor K45 measures the temperature of the engine coolant and, if the values for this parameter are high, the control unit M10 sends an earth signal from pin 53 to the relay to energize the coil. The relay sends the supply to the fan N11 from pin C connector C of the junction unit B01 .
