Location of componentsComponents DescriptionThe headlamp washer device is responsible for washing the front windscreen and the headlamp lens. The headlamp washer function is operated automatically, with the dipped beams on, when the windscreen washer is operated by a stalk lever to the right of the steering wheel.The headlamp washer function is operated automatically, with the dipped beams on, when the windscreen washer is operated by a stalk lever to the right of the steering wheel.The headlamp washer device consists of a detergent delivery pump and a nozzle in the bumpers that sprays a powerful jet onto the headlamp.The headlamp circuit is protected by a special fuse and governed by an electronic timing device, both of which are located in the junction unit.The timer operates the headlamp washer pump in a series of half-second pulses.
Functional description The headlamp washer J50 is supplied (pin P) by the direct line from the battery through the headlamp washer fuse B12 and the maxifuse J/B2 of B5 If the windscreen washer switch is operated, the steering column switch unit H5 sends a signal which reaches the headlamp washer timer J50 (pin S): it involves a line controlled by the ignition (INT/A) coming from the steering column switch unit H5 - pin 3 of connector D - supplied by the relay R1, protected by the fuse F14: both are housed in the junction unit B1. The supply for the relay R1 comes from the direct line of the maxifuse J/B1 of B5, whilst the coil is supplied by the line (INT/A) protected by the fuse B26 ( See E3020 WINDSCREEN WASH/WIPE ). With the dipped headlamps switched on, a go ahead signal reaches pin 56 of J50 from the line for fuse F5 which supplies the dipped headlamps. ( 2888832SeeE2011DIPPED HEADLAMPS ). When there are both signals at pins S and 56, the relay, inside the device J50 which supplies the electric headlamp washer pump N25 with impulses of about half a second, is energized for a certain time.
