HEADLAMP WASHER - FUNCTIONAL DESCRIPTION
FUNCTIONAL DESCRIPTION
The relay T17 in the engine compartment junction unit B1 receives a power supply from the line for fuse F9, from the engine compartment junction unit B1, whilst the energizing takes place through the ignition-operated line (INT/A) from fuse F31 of the junction unit under the dashboard B2.
The relay operates the headlamp washer pump N25 directly when an earth signal arrives from the Body Computer M1; this signal - from pin 14 of connector A - is sent on the basis of the positive windscreen washer request signal coming from the steering column switch unit H5 - pin 5 of connector A and in the presence of the dipped headlamps on enablement (pin 2 of connector I and pin 28 of connector G of M1).
