DESCRIPTION - CONTROL LIGHTS - Alfa Romeo 159 1.9 JTD 8V Da 01/06
The car is equipped with numerous light sources for optimal lighting of interior instruments and controls.Some of these are lit with the ignition ON (INT), others with the side lights on, others are dimmable in accordance with a rheostat-controlled adjustment strategy managed by the Body Computer.The Body Computer manages the lighting - with the side lights on - of:- cigar lighter and rear current socket;- controls on the front courtesy light- radio display (aftermarket version only)- radio phone preparationThe Body Computer manages (directly and via the door control units) the dimmed lighting of:- instrument panel and display;- auxiliary instrument- switches in the doors;- climate control system controls.All the other controls are lit up when the ignition is on (INT), i.e. with the TEG inserted.A brightness sensor for the automatic adjustment (day/night) of the brightness of the instrument panel is built-in; it has the task of measuring the ambient light conditions and sending this information (daytime or nightime) to the Body Computer which, on comparing this information with the state of the side lights, selects the appropriate lighting configuration for the vehicle interior (daytime or nightime mode).With this information available, the behaviour of the instrument is as follows:- In "daytime" mode the display can be adjusted to 8 settings, the graphics are switched off, the index lighting is 100% and cannot be adjusted.- In "nightime" mode the display, the graphics and the indexes can be adjusted to 8 settings and the level set will be transmitted to the components that regulate the brightness (climate control display, radio display).This adjustment is made using the "MODE", "MODE +" and "MODE -" buttons located on the steering column switch unit; there are 8 different possible settings. (fom 30% to 100% of the maximum intensity). The level set by pressing the buttons is shown on the instrument panel display; the setting is also memorized and used later on.
FUNCTIONAL DESCRIPTION - CONTROL LIGHTS - Alfa Romeo 159 1.9 JTD 8V Da 01/06
The "MODE" "+" and "-" controls, located on the left steering column switch unit lever +15, send an analogue signal to the instrument panel E50 at pin 5 of connector A.The dimmed power supply for the auxiliary instruments E20 leaves pin 5 of connector C of E50 (pin 2 of connector C provides the reference earth).The Body Computer M1 is connected via the CAN line to the instrument panel E50 from which it receives the "brightness adjustment" signal which is transmitted to the radio node and to the climate control system control unitThe power supply with the side lights switched on is provided by the Body Computer M1 - pin 40 of connector E for the cigar lighter light P50 and the rear current socket P51, in addition to the controls on the front courtesy light G10; the same lighting is sent, - pin 18 of connector H of M1 - to the controls for the radio P20 and to the preparation for the radio telephone D75.The lighting for the front door controls H44 and H50 is managed by the door control units M66 - at pin 11 of of connector D by the line protected by fuse F32 of the junction unit under the dashboard B2 , and connected via the CAN line to the Body Computer M1 .The ignition-controlled power supply line (INT), protected by fuse F35 of the junction unit under the dashboard B2, provides the lighting for the switch unit on the tunnel H35.The ignition-operated power supply line (INT), protected by fuse F49 of the junction unit under the dashboard B2, provides the lighting for the hazard warning lights control H20, the control panel to the left of the dashboard H90, the controls on the rear courtesy light G20, those on the seats I65 and I66 and the passenger side front door electric window switch H50.
