DESCRIPTION - SIDE LIGHTS / NO. PLATE LIGHTS - Alfa Romeo 159 2.2 JTS Fino a 12/05
The side lights are switched on at the first turn of the ring nut on the left steering column switch unit lever. The turning on of the side lights is managed by the Body Computer.The side lights control function is activated through the TEG on enablement signals (INT) and the command from the steering column switch unit: the four side lights are supplied in this way.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).Activation/deactivation information is sent via the CAN network: in this way, the side lights warning light in the instrument panel is also activated. The instrument panel also activates the nightime lighting.The side lights can be activated automatically by means of 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 sensitivity settings: when the dusk sensor is activated a message is shown on the instrument panel display indicating the sensitivity setting (from 1 to 3): this setting can be adjusted using the "Mode +" and "Mode -" buttons.The "parking lights" function is turned on - only with the TEG extracted - by pressing the button in the panel to the left of the steering wheel: a roger beep signals engagement. If the steering column switch unit left lever is turned (in the same way as for activating the direction indicators) it is possible to choose whether to turn on the side lights on both sides of the vehicle (lever in middle position) or only those on one side (lever downwards to select the left side, lever upwards to select the right side).The "Follow me home" function allows the dipped headlamps and the side lights to remain on even after the engine has been switched off (TEG extracted) for a period of 30 seconds or multiples thereof. The side lights warning light in the instrument panel signals that the lights have remained on. It is turned on using the lever in the same way as for activating the flasher within 2 minutes of the TEG being extracted: each time the lever is operated the time the lights remain on is increased by 30 seconds up to a maximum of 210 seconds. If the TEG is inserted or the flasher lever is pulled for more than 2 seconds, the function is excluded.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.For safe driving, if there is a fault with one of the rear bulbs, with the side lights on the brake light bulb on the corresponding side comes on dimly to simulate the brightness of the side light. The system also detects any faults in the dusk sensor: if a fault is detected, the "general failure" warning light is turned on and the information is shown simultaneously on the display.
FUNCTIONAL DESCRIPTION - SIDE LIGHTS / NO. PLATE LIGHTS - Alfa Romeo 159 2.2 JTS Fino a 12/05
Two signals (earth) are sent from the steering wheel stalk unit H5 to the Body Computer M1 that manages both side lights and low beams in manual or AUTO mode (automatic dusk sensor activation).The "Light 1" signal - is sent to pin 28 of connector G of the Body Computer M1 from the steering column switch unit H5, pin 7 of connector C. The "Light 2" signal - is sent to pin 2 of connector I of the Body Computer M1 from the steering column switch unig H5, pin 8 of connector C. The side lights are turned on manually when the "Light 1" signal is missing and the "Light 2" signal is present.The side lights are activated in AUTO mode when the Light 1 signal is not present and the Light 2 signal is not present. If both signals are present, the lights are permanently off.The side lights are automatically activated by the dusk sensor housed in the mirror P65 (signal via the A-BUS line to pin 7 of connector D of M1); the dusk sensor in P65 receives a supply from the INT line protected by fuse F49 of junction unit B2.The lights are also activated by the parking lights button located in the left switch unit H90 which sends an earth signal to pin 17 of connector H of M1.The Body Computer M1 controls the supply for the front side lights F10 (left) and F11 (right) from pins 40 and 30 of connector B, for the rear side lights F30 and F35 (left), F31 and F36 (right) and the number plate lights F50 and F51 from pins 5, 6, 9 of connector D and 38 of connector E.Via the CAN line, the Body Computer M1 is connected to instrument panel E50 to manage the side lights on warning light and, if faults are detected in the circuit or in the bulbs, the lights failure warning light; in the vent of a fault with the dusk sensor there is a specific signal.
