The system operates with the ignition key turned ON.The rearscreen wiper is operated by turning
the ring nut at the end of the right steering column switch unit
lever.The operation of the rearscreen wiper motor
is controlled intermittently by the body computer node. The rearscreen
wiper is activated in synchronization with the operation of the
windscreen wiper, but at half the frequency, in all windscreen wiper
operating conditions (intermittent/continuous).The windscreen washer function is operated
by pushing the lever gently towards the dashboard: the rearscreen
washer pump (the same one as for the windscreen washer) is activated
in this way; if the lever is kept in this position, the rearscreen
wiper will also come on; When the lever is released, the windscreen
wipers will continue to operate for several strokes. After about
six seconds, calculated from when the rearscreen wiper park position is
reached at the end of the last stroke cycle, there is an additional
rearscreen wiper stroke (after-wipe function).When the windscreen wiper is working, engaging
reverse gear automatically activates the rearscreen wiper.The rearscreen wash/wipe function is managed
entirely by the body computer node.
