Standing/parking lights, general 

The standing lights/parking lights actuation is used to mark the parked vehicle in poor visibility.

The Standing/parking lights actuation is deactivated depending on the energy status with circuit 15R Off.

A differentiation is made between the following versions of the left front lamp unit (E1) and the right front lamp unit (E2) in accordance with the vehicle equipment:

• Halogen headlamps 

  (Except CODE 631 (Static left-hand traffic LED headlamp) and except CODE 632 (Static right-hand traffic LED headlamp) and except CODE 640 (High Performance LED) and except CODE 641 (DYNAMIC LEFT-HAND TRAFFIC LED HEADLAMP) and except CODE 642 (DYNAMIC RIGHT-HAND TRAFFIC LED HEADLAMP))

• LED headlamp (static) 

  (With CODE 631 (Static left-hand traffic LED headlamp) or CODE 632 (Static right-hand traffic LED headlamp))

• LED headlamp (dynamic) 

  (With CODE 640 (High Performance LED) or CODE 641 (DYNAMIC LEFT-HAND TRAFFIC LED HEADLAMP) or CODE 642 (DYNAMIC RIGHT-HAND TRAFFIC LED HEADLAMP))

The standing/parking lights actuation is comprised of the following partial functions:

• Standing lamp actuation function sequence 
• Function sequence for standing light warning 
• Parking lights actuation function sequence 
• Function sequence for driving lights warning (except code 460 (Canada version)) 

Standing lamp actuation function sequence 

Turning the exterior lights switch (S1) to the standing lights position requests actuation of the standing lights.

The front SAM control unit (N10/6) directly reads in the status of the exterior lights switch and transmits the request "Standing lights ON" via the interior CAN (CAN B) to the rear SAM control unit (N10/8) and in addition for vehicles with LED headlamps via the interior CAN, electronic ignition lock control unit (N73) and peripherals CAN (CAN PER) to the left headlamp control unit (E1n9) and to the right headlamp control unit (E2n9).

In vehicles with CODE 550 (Trailer hitch), the front SAM control unit transmits the "Standing lights ON" request via the interior CAN to the trailer recognition control unit (N28/1).

Furthermore, the front SAM control unit transmits the "Switch on standing lights indicator lamp" request via the interior CAN, the electronic ignition lock control unit and the user interface CAN (CAN HMI) to the instrument cluster (A1), which then switches on the standing lights indicator lamp (A1e38). The symbols of the indicator lamps are accordingly shown in the digital full display (with code 464 (Digital instrument cluster full display)).

The standing lights indicator lamp is deactivated after a defined time in spite of an active function for circuit 15 OFF and an externally locked vehicle.

The tail light also has the function of a side marker light.

On vehicles with CODE 550 (Trailer hitch), the trailer recognition control unit actuates the following components of the exterior lights on the trailer via the trailer socket (X58):

• Taillights and parking lights
• License plate lights

Additional function requirements for standing lights warning 

• Standing lights ON
• Driver door OPEN
• Circuit 15C OFF

Function sequence for standing light warning 

The logic for requesting the standing lights warning function is stored in the front SAM control unit.

The left front door control unit (N69/1) sends the status of the driver door (open or closed) and the electronic ignition lock control unit sends the status of circuit 15 via interior CAN to the front SAM control unit. The front SAM control unit receives this information, uses it to generate the request to issue the standing lights warning function, and transmits the "Warning tone ON" and "Instrument cluster message ON" requests via the interior CAN, the electronic ignition lock control unit and the user interface CAN to the instrument cluster.

The instrument cluster then actuates the instrument cluster speaker (H4/61) directly. The message "Switch off lights" is shown on the instrument cluster.

Additional function requirements for parking lights actuation 

• Circuit 15R OFF

The electronic ignition lock control unit sends the status of circuit 15 to the front SAM control unit via the interior CAN.

Parking lights actuation function sequence 

By turning the exterior lights switch to the left parking lights position or the right parking lights position, the parking lights actuation is requested for the corresponding side of vehicle.

The front SAM control unit reads in the status of the exterior lights switch directly and transmits the "Parking lights ON" request to the rear SAM control unit via the interior CAN.

In vehicles with LED headlamps, the front SAM control unit transmits the request "Parking lights ON" via the interior CAN, electronic ignition lock control unit and peripherals CAN to the respective headlamp control unit.

On vehicles with CODE 550 (Trailer hitch), the front SAM control unit also sends the "Parking lights ON" request via interior CAN to the trailer recognition control unit.

The right tail light also has the function of a side marker light.

The trailer recognition control unit (with CODE 550 (Trailer hitch)) actuates the right taillight on the trailer via the trailer socket.

If the interior CAN is in "bus idle", the parking lights actuation is stored in all the control units involved until deactivation is requested by the front SAM control unit.

Additional function requirements for driving lights warning (except code 460 (Canada version)) 

• Exterior lights switch in standing lights position or parking lights position
• Rain/light sensor with additional functions (B38/2) detects darkness
• Vehicle speed v > 15 km/h

Function sequence for driving lights warning (except code 460 (Canada version)) 

The logic for requesting the driving lights warning function is stored in the front SAM control unit.

The front SAM control unit reads in the status of the exterior lights switch directly.

The light sensor (B38/2b2) in the rain/light sensor with additional functions detects the ambient brightness. The rain/light sensor with additional functions reads in the signals of the light sensor directly, evaluates them and transmits the "Low beams ON" request via the rain/light sensor LIN (LIN B16) to the front SAM control unit when it is dark.

The Electronic Stability Program control unit (N30/4) transmits the vehicle speed via the chassis FlexRay (flex E), the electronic ignition lock control unit and the interior CAN to the front SAM control unit. The front SAM control unit receives this information, uses it to generate the request to issue the driving lights warning function, and it transmits the "Warning tone ON" and "Instrument cluster message ON" requests via the interior CAN, the electronic ignition lock control unit and the user interface CAN to the instrument cluster.

The instrument cluster then actuates the instrument cluster speaker directly. "Switch on driving lights" message appears on the instrument cluster.
