2399169 - 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) and the command from the steering column switch unit: the four side lights are supplied in this way.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, via the dusk sensor, if the AUTO function is set on the steering column switch unit.The dusk sensor is an infrared device that operates at different levels of sensitivity. When the dusk sensor is activated, a message appears on the control panel display that indicates a preset sensitivity level (from 1 to 3). This intensity may be adjusted using the 'Mode +' and 'Mode -' keys. The parking lights function is switched on, with the ignition OFF, by pressing the button in the control panel to the left of the steering wheel: a roger beep signals that they have been switched on.If the left steering column switch unit lever is turned (as for activating the direction indicators) it is possible to select whether to switch on the side lights on both sides of the vehicle (lever in centre position) or on one side only (lever downwards to select the left side and lever upwards to select the right side).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 lights on is signalled by the side lights warning light in the instrument panel remaining on.The function is switched on by operating the flasher lever within 2 minutes of the ignition being switched OFF: each time the lever is operated the time the lights remain on increases by 30 seconds up to a maximum of 210 secs.Turning the ignition ON or keeping the flasher lever pulled for more than 2 seconds switches the function off.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 circuits:
- 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)
