Side Lights And License Plate Lights

DESCRIPTION 

With the key in the ON position and the ring nut in position "O" the daytime lights come on automatically; the other lights and the interior lighting remain off.

The side lights / front daytime lights are built into the headlamp and consist of LED circuits.

The rear side lights are located in the rear side light clusters and also have LED circuits.

With the ignition in the ON position, when the ring nut is turned forwards the dipped beam headlights are activated, the daytime lights switch off and the side lights, dipped beam headlights and number plate lights are switched on.

The side lights warning light in the instrument panel lights up.

The parking lights function (PARKING) makes it possible to switch on the side lights and the number plate lights with the ignition on STOP, to signal the presence of the vehicle whilst it is parked.

With the ignition key in the OFF position or extracted, all the side lights and number plate lights come on when the ring nut is turned forwards. The side lights warning light in the instrument panel switches on.

The function is deactivated by moving the steering column stalk lights ring nut to the OFF position or at Key ON. This last operation resets the function and the Body Computer controls the lights depending on the command selected using the steering column stalk ring nut.

The "Follow me home" function allows the dipped beam headlights and the side lights to remain on even after the engine has been switched off (key in STOP position or 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 engaged using the lever in the same way as for activating the flasher within 2 minutes of the ignition being turned to STOP: 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 excluded if the ignition is turned to KEY or if the flasher lever is operated for more than 2 seconds.

The switching on of the side lights is managed by the Body Computer.

The number plate light and numerous other interior lights for lighting the passenger compartment, instruments and controls are activated together with the side lights.

Activation and/or deactivation information is sent via the CAN: in this way, the side lights warning light in the instrument panel is also activated. The instrument panel also activates the night lighting for the icons.

The correct operation of the lights is checked by the daytime lights, side lights and number plate lights "check" function: the following is checked for each of the circuits:

• open circuit or missing bulb
• short circuit to ground (bulb s.c. or wiring s.c. to ground)
• short circuit to battery voltage (wiring short circuited to Vbatt)

When one of the situations described above is verified, 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.

FUNCTIONAL DESCRIPTION 

- There is a single (ground) signal sent by the steering column stalk H005 to the Body Computer M001 that manages both the side lights and the dipped headlights: from pin 3 of H005 to pin 38 of connector F of M001; the signal sent is coded by means of resistive dividers so that multiple information can be sent by the steering column stalk to the Body Computer via a single connection.

• The reference ground reaches pin 10 of H005 from pin 34 of connector F of M001.
• The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment control unit B001.
• The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E: this signal is used, amongst other things, to "wake up the network".
• The ground reference reaches pins 9, 10 of connector E of Body Computer M001.
• The Body Computer M001 controls the power supply for the daytime running lights and the side lights in the headlamps F069 (left) and F070 (right) from pins 13, 28, 29, 30 of connector B.
• The Body Computer M001 controls the power supply for the fixed rear side lights F030 (left) and F031 (right) from pin 59 of connector C.
• The feedback signals for the management of the electronic device are sent to pins 35, 36 of connector C of M001.
• It also controls the number plate lights F050 and F051 from pin 15 of connector C of M001.
• Body Computer M001 is connected through the CAN line to the instrument panel E050, to manage "the side lights on" warning light and, if a fault is detected in the circuit or bulbs, the "lights failure" warning light.
