Function requirements, general 

Exterior lights (ABL), general 

The exterior lights control all the safety and comfort-relevant functions of the front, side and rear lights of the vehicle.

The exterior lights comprise the following subfunctions:

Further subfunctions are described in separate information:

Function sequence, on-board network increase 

When the on-board electrical system voltage is decreased by the on-board electrical system management below the minimum voltage of a light function during normal driving operation, the front SAM control unit can suppress shutoff of the corresponding light function with the aid of the on-board electrical system increase. To do so, the front SAM control unit requests the minimum voltage required for the corresponding light function. The light functions for which the on-board electrical system increase is activated can be defined at the end of the production line.

The following functions can be coded:

Function sequence for switching off the exterior lights 

Switching off the exterior lights prevents the on-board electrical system battery (G1) from being discharged by the active low beam and standing light actuation.

The low beams may be switched on due to the auto on/off headlamps, the daytime running lights or manually via the exterior lights switch. A prerequisite for this is that the status of circuit 15 is On.

If circuit 15 is Off, the low beams are switched off.

The standing lights may be on due to the low beams having been manually switched on, due to the auto on/off headlamps or the daytime running lights, or they can be switched on manually via the exterior lights switch. If the standing lights have been activated because of the manually activated low beams, auto on/off headlamps or the daytime running lights, and if the driver door is opened at circuit 15C ON, the standing lights are switched off.

If the standing lights were manually switched on, and the exterior lights switch set to the standing lights position, then on vehicles up to 31.5.11, they are not switched off.

In vehicles as of 1.6.11 the standing lights are switched off when the on-board electrical system management determines that the engine's starting capability is impaired through the discharged on-board electrical system battery.

IMPORTANT If the Ambient illumination function is activated via the instrument cluster, it automatically switches itself on when the engine is turned off. The standing lights remain switched on for a fixed time interval of t = 60 s.

The Ambient illumination function is described in the separate information "Headlamp switch-off delay (SWA), function".
