DESCRIPTION - WINDSCREEN WASH/WIPE - Fiat GRANDE PUNTO 1.3 Multijet

The windscreen wash/wipe system is activated by the lever located on the right of the steering wheel, with the following functions: there are five possible positions for the stalk lever to which the following functions correspond:- windscreen wiper off (stationary);- intermittent/automatic operation;- continuous slow operation;- continuous fast operation;- "antipanic" temporary fast operation (unstable position, turning the lever downwards).In the intermittent/automatic operation position three different positions can be selected by turning the ring nut:- on the "LOW" version the different intermittent speeds are switched on (from the slowest to the fastest;- on the "HIGH" version with the rain sensor: the different sensor settings are switched on: the activation of the rain sensor involves a windscreen wiper arm stroke as feedback to confirm that it has been switched on.The frequency of the windscreen wiper strokes is automatically adjusted depending on the amount of water on the windscreen detected by the sensor: the frequency varies continuously from nil (no stroke - windscreen dry) to wiping at the second continuous speed (heavy rain).The windscreen washer function can be activated by pulling the lever toward the steering wheel: this activates the windscreen washer pump: keeping the lever pulled also switched on the windscreen wiper in accordance with a specific control logic: the windscreen wiper is activated at the first speed: when the windscreen washer control is no longer present, an additional stroke is carried out.The windscreen washer circuit is protected by a special fuse located on the Body Computer. The windscreen wiper and windscreen washer may be operated by a supply that is ignition-operated except during start-up (INT/A).The correct operation of the rain sensor is controlled by the check function. If the rain sensor is not working properly, the windscreen wiper will operate intermittently whilst the instrument panel display will show the sensor failure.

FUNCTIONAL DESCRIPTION - WINDSCREEN WASH/WIPE - Fiat GRANDE PUNTO 1.3 Multijet

A single signal (earth) is sent from stalk unit H5 to Body Computer M1, which manages all the windscreen wiper commands: from pin 7 of H5 to pin 54 of connector D of M1; the signal is coded via resistance dividers so that multiple information can be sent via a single connection from the stalk unit to the Body Computer. A reference earth reaches pin 10 of H5 from pin 34 of connector D of M1.Similarly, the windscreen washer commands are sent from pin 5 of H5 to pin 55 of connector D of M1.Body Computer M1 - connector G - is supplied directly from the battery from a line protected by maxifuse F2 of engine compartment control unit B1. It is supplied by an ignition-operated supply (INT) at pin 32 of connector D; pin 10 of connector H of M1 provides the Body Computer with a reference earth.According to the function selected, Body Computer M1 sends the following control signals to the wiper motor N15:- from pin 16 of connector E for fast operation;- from pin 32 of connector E for slow and/or intermittent operation,- pin 22 of connector A on the other hand, receives the earth signal coming from the motor end of travel cam which stops operation. The windscreen wiper motor N15 is then earthed.Body Computer M1 sends two signals from pins 3 and 14 of connector E, which operates the pump of windscreen washer N22, which turns to send washer fluid forward to the windscreen wiper. The supply line from the pump is protected by fuse F42 located on Body Computer M1.Rain senor K85 is supplied from the INT line of Body Computer M1 - pin 7 of connector E and sends an automatic operation signal to pin 35 of connector A of M1 via the A-BUS serial line.The Body Computer M1 is connected via the CAN line to the instrument panel E50 to manage the failure signal if there are problems with the rain sensor.
