Description - HEATED SEATS - Fiat DOBLO 1.6 16v da 12/03
The front seat may be optionally fitted with a special heating system (consisting of two heater elements located in the cushion and squab): these heat the seat to ease the discomfort of entering a cold passenger compartment in very cold weather, e.g. when the car is left outside for long periods during winter.The seat heating circuit is operated by a switch on the actual seat and is protected by a special fuse and controlled by a relay which supplies other services controlled by the ignition.
Functional description - HEATED SEATS - Fiat DOBLO 1.6 16v da 12/03
The seat heating circuit is controlled by the relay R13 . It is supplied directly by the battery via a line protected by fuse F2 housed in the engine compartment junction unit B01 .The coil energizing signal consists of an earth signal leaving pin 14 of connector X of the body computer M01 .The output supply signal from the relay R13 passes through fuse F45 and leaves the junction unit under the dashboard B02 from pin 4 connector D. This signal then reaches pin 2 of the heater pad I65 contained in the driver''s seat. When the switch is turned on the supply reaches the heater pad O40 which heats up the seat.The heater pad is earthed via pin 1.The operation of the switch I65 also lights up the LED in the actual switch.
