Model 166 

as of Model year 2016 

Model 292 

Function requirements, general 

• No overvoltage or undervoltage (operating voltage range U ≥ 8 ≤ 17.5 V)

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 a circuit 15R OFF status.

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 SAM control unit directly reads in the status of the exterior lights switch and activates the standing lights actuation.

On vehicles with CODE 550 (Trailer hitch), the SAM control unit also sends the "Standing light ON" request over the interior CAN to the trailer recognition control unit (N28/1).

At the same time, the SAM control unit sends the "Switch on standing lights indicator lamp" request over the interior CAN to the instrument cluster (A1), which then switches on the standing lights indicator lamp (A1e38).

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

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

• On vehicles without CODE 640 (High-performance LED) and without CODE 641 (Dynamic left-hand traffic LED headlamp) and without CODE 642 (Dynamic right-hand traffic LED headlamp) :
  • Left front side marker lamp (E1e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Left parking light, standing light and daytime running light (E1e13)

The SAM control unit uses the chassis CAN 2 (CAN E2) and left headlamp control unit (E1n9) to actuate the following components in the left front lamp unit:

• On vehicles with CODE 640 (High Performance LED) or CODE 641 (DYNAMIC LEFT-HAND TRAFFIC LED HEADLAMP) or CODE 642 (DYNAMIC RIGHT-HAND TRAFFIC LED HEADLAMP) :
  • Left front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Left parking light, standing light and daytime running light

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

• On vehicles without CODE 640 (High-performance LED) and without CODE 641 (Dynamic left-hand traffic LED headlamp) and without CODE 642 (Dynamic right-hand traffic LED headlamp) :
  • Right front side marker lamp (E2e6) (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Right parking light, standing light and daytime running light (E2e13)

The SAM control unit uses the chassis CAN 2 and right headlamp control unit (E2n9) to actuate the following components in the right front lamp unit:

• On vehicles with CODE 640 (High Performance LED) or CODE 641 (DYNAMIC LEFT-HAND TRAFFIC LED HEADLAMP) or CODE 642 (DYNAMIC RIGHT-HAND TRAFFIC LED HEADLAMP) :
  • Right front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Right parking light, standing light and daytime running light

The 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 taillight (E3e16)
• Inner left rear lamp unit (E3/1)
  • 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 taillight (E4e16)
• Inner right rear lamp unit (E4/1)
  • Inner right taillight (E4/1e2)
• Left license plate lamp (E19/1) (Model 292)
• Right license plate lamp (E19/2) (Model 292)
• Left liftgate license plate lamp (E19/3) (Model 166)
• Right liftgate license plate lamp (E19/4) (Model 166)

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) :

• Taillamps and parking lamps
• License plate lights

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 SAM control unit.

Additional function requirements for lights on reminder 

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

Function sequence for lights on reminder warning 

The logic for requesting the lights on reminder function is stored in the 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 (N73) sends the circuit 15 status over the interior CAN to the SAM control unit.

The SAM control unit receives this information, uses it to generate a request to issue the light warning function, and then sends a "Warning tone ON" and an "Instrument cluster message ON" request over the interior 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 over the interior CAN to the SAM control unit.

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 SAM control unit directly reads in the status of the exterior lights switch and activates the parking lights actuation.

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

Left parking light:

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

• On vehicles without CODE 640 (High-performance LED) and without CODE 641 (Dynamic left-hand traffic LED headlamp) and without CODE 642 (Dynamic right-hand traffic LED headlamp) :
  • Left front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))
  • Left parking light, standing light and daytime running light

The SAM control unit uses the chassis CAN 2 and left headlamp control unit to actuate the following components in the left front lamp unit:

• On vehicles with CODE 640 (High Performance LED) or CODE 641 (DYNAMIC LEFT-HAND TRAFFIC LED HEADLAMP) or CODE 642 (DYNAMIC RIGHT-HAND TRAFFIC LED HEADLAMP) :
  • Left front side marker light (with CODE 460 (Canada version) or CODE 494 (USA version))
