DESCRIPTION - REAR WINDOW WASH/WIPE - Fiat GRANDE PUNTO 1.4 16v

When the rearscreen wiper ring nut located on the right steering column switch unit lever is moved to the ON position, the rearscreen wiper is activated in one of the following modes:- intermittent: with a pause of 2.7 secs. between one stroke and the next- subject to the windscreen wiper (if there is a simultaneous windscreen/rearscreen wiper request): synchronous operation at half the frequency of the windscreen wiper- continuous: if reverse gear is engaged.767With the windscreen wipers working, if reverse gear is engaged, the rearscreen wiper is automatically activated: this function is managed by the Body Computer, which receives information from the engine control unit via the CAN networkPushing the right steering column switch unit lever activates the rear washing. Keeping the lever pushed for more than 0.5 secs automatically activates the rearscreen wiper at the continuous speed.When the control is released there are a further 3 strokes to clean the rearscreen plus another one 6 seconds later (to remove any drips).If the rearscreen wiper was already activated before the washing command using the lever, the washing logic is only effective for activating intermittent operation.The rearscreen washer circuit is protected by a special fuse located on the Body Computer. The rearscreen wiper and rearscreen washer may be operated by a supply that is ignition-operated except during start-up(INT/A).

FUNCTIONAL DESCRIPTION - REAR WINDOW WASH/WIPE - Fiat GRANDE PUNTO 1.4 16v

A single signal (earth) is sent from stalk unit H5 to Body Computer M1, which manages all the rearscreen wiper commands: from pin 4 of H5 to pin 29 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.Body Computer M1 sends a control signal to the rear wiper motor N16 from pin 15 of connector E:Pin 24 of connector A on the other hand, receives the earth signal coming from the motor end of travel cam which stops operation. The rearscreen wiper motor N16 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.
