Function requirements, general 

• No undervoltage or overvoltage

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 15 Off.

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) 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) and in vehicles with the full LED version of the lamp units also 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).

At the same time, the front SAM control unit transmits the "Switch on standing light 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 light indicator.

The standing lights indicator is switched off after a defined period if circuit 15 is OFF and the vehicle has been locked from the outside, despite the function being active.

Vehicles with halogen version of lamp units: 

The front SAM control unit actuates the following components directly:

• Left position light and daytime running light (E1e27)
• Right position light and daytime running light (E2e27)

Vehicles with full LED version of lamp units: 

The headlamp control units actuate the following components directly:

• Left front lamp unit:
  • Inner left position light and daytime running light (E1e28)
  • Outer left position light and daytime running light (E1e29)
  • Left front side marker light (E1e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
• Right front headlamp unit:
  • Inner right position light and daytime running light (E2e28)
  • Outer right position light and daytime running light (E2e29)
  • Right front side marker light (E2e6) (with CODE 460 (Canada version) or CODE 494 (USA version))

The rear SAM control unit actuates the following components directly: 

• Left rear lamp unit (E3):
  • Left taillight and parking lamp (E3e2)
• Right rear lamp unit (E4):
  • Right taillight and parking lamp (E4e2)
• Inner left rear lamp unit (E3/1):
  • Inner left taillight (E3/1e2),
• Inner right rear lamp unit (E4/1):
  • 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):

• Parking and taillights
• License plate lights

Additional function requirements for standing lights warning 

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

Function sequence for standing lights 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 light ON" request via the interior CAN to the rear SAM control unit and also in vehicles with the full LED version of the lamp units via the interior CAN, the electronic ignition lock control unit and the periphery 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.

Left parking light: 

Vehicles with halogen version of lamp units: 

The front SAM control unit actuates the following components directly:

• Left position light and daytime running light

Vehicles with full LED version of lamp units: 

The left headlamp control unit actuates the following components directly:

• Inner left position light and daytime running light
• Outer left position light and daytime running light
• Left front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))

The rear SAM control unit actuates the following components directly: 

• Left taillamp and parking lamp
• Left inside taillight

In vehicles with code 550 (Trailer hitch), the trailer recognition control unit actuates the left taillight via the trailer socket.

Right parking light: 

Vehicles with halogen version of lamp units: 

The front SAM control unit actuates the following components directly:

• Right position light and daytime running light

Vehicles with full LED version of lamp units: 

The right headlamp control unit actuates the following components directly:

• Inner right position light and daytime running light
• Outer right position light and daytime running light
• Right front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))

The rear SAM control unit actuates the following components directly: 

• Right taillamp and parking lamp
• Right inside taillight

In vehicles with code 550 (Trailer hitch), the trailer recognition control unit actuates the right taillight 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.
