323000065 - E2010 SIDE LIGHTS/NUMBER PLATE LIGHT - DESCRIPTION

DESCRIPTION

The side lights come on when the ring nut on the steering column switch unit left lever is turned to the first position.The switching on of the side lights is managed by the Body Computer.The side light control function takes place with the key set to ON or with the key to OFF or removed or for parking lights and follow-me-home function.The number plate light and numerous other interior lights for lighting the passenger compartment, instruments and controls are activated together with the side lights (these are described and explained in the wiring diagrams for the relevant components).    See E2535 CONTROL LIGHTSThe activation/deactivation information is sent to the instrument panel by the Body Computer via the CAN: in this way the side lights warning light in the instrument panel is lit and serigraphy night time illumination is activated.The parking lights function makes it possible to switch on the side lights and the number plate lights to signal the presence of the vehicle whilst it is parked. Activation can only take place with the key to OFF or removed, by operating the lighting control wheel on the steering wheel interface.The function is deactivated by moving the steering wheel interface lighting control wheel to the OFF position or the ignition key to the ON position. This last operation resets the function and the Body Computer controls the lights depending on the command selected using the steering column switch unit ring nut.The follow me home function allows the dipped headlights and the side lights to remain on even after the engine has been switched off (key in STOP position) for a period of 30 seconds or multiples thereof. The lights being kept on is signalled by the side lights warning light in the instrument panel coming on together with the message in the display for as long as the function remains activated. It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the key being switched to OFF or removed: each time the lever is operated, the period for which the lights are on is increased by 30 seconds to a maximum of 210 seconds. The function is deactivated if the key is switched to ON or if the flasher lever is operated for more than 2 seconds.The correct operation of the lights is checked by the side lights and no. plate lights check function: the following is checked for each of the circuits:- circuit open or bulb missing- short-circuit to earth (bulb s.c. or wiring s.c. to earth)- short circuit to battery voltage (wiring short circuited to Vbatt)When one of the situations described above is ascertained, the Body Computer makes the failure status available to the CAN: a special "lights failure" warning light comes on in the instrument panel and, at the same time, the information is shown in the display.The engagement of the side lights enables the switching on of the fog lights using the special control in the left panel.    See E2030 FOG LIGHTS
