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 lights on reminder warning 
• Parking lights actuation function sequence 

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) reads in the status of the exterior lights switch directly and transmits the "Standing lights ON" request via the interior CAN (CAN B) to the rear SAM control unit (N10/8).

In vehicles with LED headlamps, the front SAM control unit transmits the "Standing lights ON" request via the interior CAN, the electronic ignition lock control unit (N73) and the periphery CAN (CAN PER) to the left headlamp control unit (E1n9) and 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 standing lights indicator lamp is switched off after a defined time with circuit 15R Off and the vehicle locked from the outside, in spite of the function being active.

The front SAM control unit actuates the following components directly:

• Left front lamp unit
  • Left front side marker lamp (E1e6) (with CODE 460 (Canada version) or CODE 494 (USA version) (Halogen headlamp or LED headlamp (static)))
  • Left parking light, standing light and daytime running light (E1e13) (halogen headlamp)
• Right front lamp unit
  • Right front side marker light (E2e6) (with CODE 460 (Canada version) or CODE 494 (USA version) (Halogen headlamp or LED headlamp (static)))
  • Right parking light, standing light and daytime running light (E2e13) (halogen headlamp)

The left headlamp control unit (LED headlamp) actuates the following components in the left front lamp unit directly:

• Left front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version) (LED headlamp (dynamic)))
• Left parking light, standing light and daytime running light (model 205)
• Left position light, daytime running light and turn signal light (E1e25) (model 253 with LED headlamps (static) or model 253 with LED headlamps (dynamic) except ECE vehicles)
• Left position light, daytime running light, turn signal light and ambient light (E1e26) (model 253 with LED headlamps (dynamic), ECE vehicles)

The right headlamp control unit (LED headlamp) actuates the following components in the right front lamp unit directly:

• Right front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version) (LED headlamp (dynamic)))
• Right parking light, standing light and daytime running light (model 205)
• Right position light, daytime running light and turn signal light (E2e25) (model 253 with LED headlamps (static) or model 253 with LED headlamps (dynamic) except ECE vehicles)
• Right position light, daytime running light, turn signal light and ambient light (E2e26) (model 253 with LED headlamps (dynamic), ECE vehicles)

The rear SAM control unit actuates the following components directly:

• Left rear lamp unit (E3):
  • Left side marker light (E3e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Outer left brake light and taillight (E3e11) (model 205.3/4)
  • Outer left taillight (E3e16) (model 205.3/4, 253.3)
  • Left taillight (E3e18) (model 205.0/1/2, 253.9)
• Inner left rear lamp unit (E3/1) (model 205.2/3/4, 253):
  • Inner left taillight (E3/1e2),
• Right rear lamp unit (E4):
  • Right side marker light (E4e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Outer right brake light and taillight (E4e11) (model 205.3/4)
  • Outer right taillight (E4e16) (model 205.3/4, 253.3)
  • Right taillight (E4e18) (model 205.0/1/2, 253.9)
• Inner right rear lamp unit (E4/1) (model 205.2/3/4, 253):
  • Inner right taillight (E4/1e2)
• Left license plate lamp (E19/1)
• Right license plate lamp (E19/2)

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):

• Tail amps and parking lamps
• License plate lights

Additional function requirements for lights on reminder 

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

Function sequence for lights on reminder warning 

The logic for requesting the lights on reminder 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 light warning function, and it sends the "Warning tone ON" and "Instrument cluster message ON" requests via interior CAN, electronic ignition lock control unit and user interface CAN to the instrument cluster.

The instrument cluster then actuates the instrument cluster speaker (H4/61) directly. The "Switch off light" message appears in the multifunction display (A1p13) of the instrument cluster.

Additional function requirements for parking lights actuation 

• Circuit 15C 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 "Parking lights ON" request via the interior CAN, the electronic ignition lock control unit and the periphery CAN to the left headlamp control unit and the right 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.

Left parking light: 

The front SAM control unit actuates the following components in the left front lamp unit directly:

• Left front side marker lamp (with CODE 460 (Canada version) or CODE 494 (USA version) (Halogen headlamps or in LED headlamps (static)))
• Left parking light, standing light and daytime running light (halogen headlamp)

The left headlamp control unit (LED headlamp) actuates the following components in the left front lamp unit directly:

• Left position light, daytime running light and turn signal light (model 253 with LED headlamps (static) or model 253 with LED headlamps (dynamic) except ECE vehicles)
• Left position light, daytime running light, turn signal light and ambient light (model 253 with LED headlamps (dynamic), ECE vehicles)

The rear SAM control unit actuates the following components directly:
