Standing/Parking Lights Actuation, Function - GF82.10-P-3060RR

Model 190 

Function requirements, general 

• No overvoltage or undervoltage

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 status circuit 15R OFF.

The standing/parking lights actuation includes the following subfunctions:

• 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 with fuse and relay module (N10/1) reads in the status of the exterior lights switch directly and sends the "Standing lights ON" request via interior CAN (CAN B) to the rear SAM control unit with fuse and relay module (N10/2) and via chassis CAN 2 (CAN E2) to the left headlamp control unit (E1n9) and to the right headlamp control unit (E2n9).

At the same time, the front SAM control unit sends the "Switch on standing lights indicator lamp" request via the interior CAN, AMG gateway control unit (N93/9), and user interface CAN (CAN HMI) to the instrument cluster (A1), which then switches on the standing lights indicator lamp (A1e38).

With status circuit 15R OFF, the standing light indicator lamp is deactivated after a defined period even if the function is active.

The left headlamp control unit directly actuates the following components in the left front lamp unit (E1):

• Left front side marker light (E1e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
• Standing light in left parking light and daytime running light (E1e13)

The right headlamp control unit directly actuates the following components in the right front lamp unit (E2):

• Right front side marker light (E2e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
• Standing light in right parking light and daytime running light (E2e13)

The rear SAM control unit actuates the following components directly:

• Left rear lamp unit (E3):
  • Standing light in left taillight (E3e18)
  • Side marker light in left taillight (with CODE 460 (Canada version) or CODE 494 (USA version))
• Right rear lamp unit (E4):
  • Standing light in right taillight (E4e18)
  • Side marker light in right taillight (with CODE 460 (Canada version) or CODE 494 (USA version))
• Left license plate lamp (E19/1)
• Right license plate lamp (E19/2)

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 lights on reminder 

• Standing lights ON
• Driver door OPEN
• Circuit 1 5C 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 door control unit (N69/1) sends the status of the driver door (open or closed) and the electronic ignition lock control unit (N73) sends the circuit 15 status via 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 light warning function, and sends the "Acoustic warning ON" and "Instrument cluster message ON" requests via the interior CAN, AMG gateway 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 1 5C OFF

The electronic ignition lock control unit sends the status of circuit 15 to the front SAM control unit over 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 rear SAM control unit actuates the following components directly:

• Left rear lamp unit:
• Parking light in left taillight
• Side marker light in left taillight (with CODE 460 (Canada version) or CODE 494 (USA version))

Right parking light:

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

The front SAM control unit reads in the status of the exterior lights switch directly and sends the "Parking lights ON" request via interior CAN to the rear SAM control unit and via chassis CAN 2 to the left headlamp control unit and the right headlamp control unit.

Left parking light: 

The left headlamp control unit 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))
• Parking light in left parking light and daytime running light

• Right front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))
• Parking light in right parking light and daytime running light

The rear SAM control unit actuates the following components directly:

• Right rear lamp unit:
  • Parking light in right taillight
  • Side marker light in right taillight (with CODE 460 (Canada version) or CODE 494 (USA version))

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.
