REARSCREEN WASH/WIPE DESCRIPTION

The rearscreen wiper is activated by turning the ring nut on the end of 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 rear wiper comes on:

- in synchrony with the windscreen wiper but at half the rate of the windscreen wiper under all windscreen wiper operating conditions (intermittent/continuous).

- continuous mode with rate of 45 beats per minute.

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 Body Computer which sends the steering column switch unit electronic device this information coming from the reversing lights function control logic

the rearscreen wash/wipe may be activated only with the ignition device ON (INT/A).

The windscreen wash/wipe circuit is protected by a specific fuse and controlled by the ignition-operated exclusion relay located in the junction unit under the dashboard.
