DescriptionThe headlamp washer device is responsible for washing the frontwindscreen and the headlamp lens.The headlamp washer function is managedby the Body Computer which automatically operates the headlamp washers- with the dipped headlamps on - when the windscreen washer is operated,via the lever on the right of the steering wheel.The headlamp washer device consists of adetergent delivery pump and a nozzle in the bumpers that spraysa powerful jet onto the headlamp.A timer operates the headlamp washer pumpin a series of half second pulses.The headlamp washer circuit is protectedby a fuse and adjusted by a specific relay, located in the enginecompartment control unit.
Functional description The relay T17 for the engine compartment junction unit B1is supplied by the line for fuse F9 for the engine compartment junctionunit B1 and is energized by the line 'controlled by the ignition'(INT/A) from fuse F31 of the underdashboard junction unit B2. The relay operates the headlamp washer pump N25directly when the command arrives from the Body Computer M1; thiscontrol signal from pin 14 of connector A is sent according to thescreen washer request coming from the steering column switch unit H5 pin 5 of connector A and the dipped headlamps activationenablement (pin 2 of connector I of M1).
