DescriptionThe rearscreen wiper is operated by turning the ring nut on theend of the lever located on the right of the steering wheel.The operation of the rearscreen wiper motoris controlled intermittently by the electronic device inside thesteering column switch unit which also manages the windscreen wash/wipe:the activation of the rearscreen wiper is synchronized with thewindscreen wiper, but the frequency is half that of the windscreenwiperBy pushing the lever gently towards thesteering wheel the rearscreen washer function is activated; thesame (two-way) pump is used as for the windscreen washer, but itrotates in the opposite direction and sends the detergent fluidto the rear, following the same control logic: the rearscreen wiperis activated the, as the rearscreen washer command is over, an additionalstroke is carried out. When the windscreen wiper is working, engagingreverse gear automatically activates the rearscreen wiper: thisfunction is managed by the Body Computer which forwards this information,coming from the reversing lights function control logic, to theelectronic device in the steering column switch unit 2427919SeeE2022REVERSING LIGHTS . The rearscreen wash/wipe can only be operatedwith the ignition switched ON.The rearscreen wash/wipe circuit is protectedby a specific fuse (which also protects the windscreen wash/wipecircuit) and operated by the ignition-operated relay, located inthe junction unit.The windscreen wash/wipe circuit is protectedby a specific fuse and is operated by the ignition-operated relaylocated in the underdashboard control unit.The rearscreen wash/wipe can be operatedwith the ignition ON (INT/A).
Functional descriptionThe electronic device inside the steering column switch unitH5 and the controls on the right lever are supplied at pin 11 ofconnector A by the line 'controlled by the ignition' (INT/A) ofrelay T12 protected by fuse F43, both housed in the underdashboardcontrol unit B2. The electronic section of the steering columnswitch unit H5 which manages the rearscreen wiper function issupplied at pin 12 of connector C from the same line 'controlledby the ignition' (INT/A) for the relay T12 protected by the fuseF52, housed in the underdashboard junction unit B2. Pin 7 of connector A and pin 9 of connectorC of H5 are earthed. When the rearscreen wiper function is switchedon, the steering column switch unit H5 sends the control signalto the rearscreen wiper motor N16 from pin 1 of connector B; pin 2,on the other hand, receives the earth signal coming from the motorend of travel cam which stops operation. The motor N16 isthen earthed. The windscreen/rearscreen washer switch,when operated, sends two signals from pins 10 and 12 of connectorA which operate the windscreen/rearscreen washer pump N22 directly. Pin 3 of connector A receives the automaticrearscreen wiper activation signal coming from the Body Computer M1 ,pin 1 of connector A 2427919SeeE2022REVERSING LIGHTS .
