Description - WINDSCREEN WASH/WIPE - Fiat DUCATO 2.8 JTD 8V fino a 02/05


The system is operated with the key ON.The windscreen wiper system is operated by the stalk switch located to the right of the steering wheel.This stalk may be moved to five different positions that correspond to the following functions:windscreen wiper off (stationary);intermittent operation (up to four types of intermittent setting are present);continuous fast operation (first speed);continuous fast operation (second speed);temporary operation (unstable stalk position), stalk retursn to neutral position when released and automatically deactivates the windscreen wiper.The windscreen wiper function can be deactivated by pulling the stalk slightly toward the steering wheel: the windscreen washer pump is then operated. The wiper comes on too if the stalk remains pulled back (continuous operation). The wiper continues to work for a few sweeps when the stalk is released.Windscreen wiper operation is governed by an electronic device built into the stalk unit. This generates the intermittent function and controls operation of the wiper motor.The windscreen wash/wipe circuit is protected by a fuse and controlled by a relay in the engine bay junction unit and specific fuses housed in the junction unit under the instrument facia.

Operational Description - WINDSCREEN WASH/WIPE - Fiat DUCATO 2.8 JTD 8V fino a 02/05


The enginebay junction unit is supplied directly by battery control unit B099, at connector F, pin 1.This power supply flows through internal fuse F08 and reaches relay T08. Relay coil T08 is earthed - from pin 26 connector C - and supplied with key on - from pin 11 connector C. The ignition-operated supply comes from under-facia junction unit B002 - pin 1 connector A -, protected by fuse F31, located in the control unit. When relay T08 is excited, power goes to wiper motor N015 - pin 3 - and stalk unit H005 - pin 2 connector -. Power reaches the stalk unit from underfacia junction unit B002, protected by fuse F43, housed in the control unit.According to the function selected, stalk unit H005 - connector A - sends the following control signals to the electronic device inside wiper motor N015:from pin 5 for operation at first speed;from pin 4 for operation at second speed;from pin 2 for zeroing.Stalk unit H005 takes earth signal C015 from connector C pin 5 and supplies washer motor N020 from pin 1 of connector A.
