REARSCREEN WASH/WIPE - DESCRIPTION

DESCRIPTION

The rearscreen wiper is activated by turning the wheel on the lever on the right of the steering wheel.

The operation of the rearscreen wiper motor is controlled intermittently by the electronic device that also manages the windscreen wash/wipe function. the activation of the rearscreen wiper is synchronized with that of the windscreen wiper, but the frequency is half that of the windscreen wiper

Pushing the lever gently towards the steering wheel activates the rearscreen washer function, via the windscreen washer (two way) pump, which rotates in the opposite direction and sends the detergent fluid towards the back following the same control logic: the rearscreen wiper is activated and then, when the rearscreen washer command ends, an additional stroke is carried out.

With the windscreen wipers working, if reverse gear is engaged, the rearscreen wiper is automatically activated: this function is managed by the steering column switch unit electronic device which receives this information from the reversing lights switch

See E2022 REVERSING LIGHTS

The rearscreen wiper and rearscreen washer may be operated by a supply that is ignition-operated except during start-up (INT/A).

The windscreen wash/wipe circuit is protected by two dedicated fuses (one also protects the rearscreen wash/wipe circuit) and controlled by the ignition-operated exclusion relay located in the junction unit.
