2427900 - E2010 SIDE LIGHTS / NO. PLATE LIGHTS - Description

Description

The side lights are switched 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 function of controlling the side lights is activated by the ignition key in ON position (INT) go ahead signals and the command from the steering column switch unit: the side lights are supplied two at a time, on the left side and the right side.Turning on the side lights also turns on the number plate lights and numerous other interior lights for passenger compartment lighting and instrument & control lighting (these lines are described and illustrated in the diagrams for the components to which they refer).The activation and/or deactivation information is sent via the ACN: in this way the 'Side Lights' warning light in the instrument panel is also switched on.The instrument panel also activates the serigraphy night lighting.The side lights are activated automatically, if the AUTO function on the steering column switch unit is set, via the dusk sensor.

The 'park' function for the side lights is switched on when the PARK button in the switch panel is pressed:

• if the direction indicators are not activated, the parking lights come on on both sides of the vehicle, like the no. plate lights and the side lights warning light;
• if the direction indicator on one side is on, the parking lights only come on on that side, whilst the no. plate lights and the side lights warning light do not come on.

The 'Follow me home' function is designed to keep the dipped headlamps and the side lights on after the engine has been switched off (key in OFF position) for a time of 30 seconds or multiples thereof.Keeping the dipped headlamps on is signalled by the side lights warning light in the instrument panel remaining on.The funciton is switched on by operating the flasher lever within 2 minutes: each time the lever is operated the time the lights remain on increases by 30 seconds up to a maximum of 210 secs.Operating the flasher lever for longer than 2 seconds switches the function off; the function is also switched off if the ignition key is turned to the ON position.

The correct operation of the lights is controlled by the side lights and no. plate lights 'check' function: the following is controlled for each of the two circuits (right branch and left branch):

• open circuit or bulb missing
• short circuit to earth (bulb short circuit or wiring short circuit to earth)
• short circuit to Vbatt (wiring short circuit to Vbatt)

The system also detects any problems with the dusk sensor.If one of the situations described above is detected, the Body Computer notifies the CAN of the failure state: a special 'failure' warning light comes on in the instrument panel and, at the same time, the information is shown on the display.
