The driver SAM control unit actuates the following components:
- Left standing and parking lights (E1e3)
- Right standing and parking lights (E2e3)
- Left front side-marker lamp (United States Of America) (E6/1) and right front side-marker lamp (United States Of America) (E6/2)

Function sequence, lights on reminder warning
The logic for actuation of the lights on reminder warning function is stored in the instrument cluster (A1).
The "standing lights actuation active" status message is sent by the driver SAM control unit, the status of the driver door by the rear SAM control unit and status circuit 15 by the EIS [EZS] control unit (N73) to the interior CAN.

The instrument cluster receives this information, uses it to generate a request to issue the lights on reminder warning function and actuates the warning buzzer (A1h1) for an acoustic output of the lights on reminder warning.
