Illustrated on model 221.0 

Location 

The TLC control unit is located in the trunk at the right rear.

Task 

The TLC control unit has the following tasks:

• Reading in of sensors and signals 
• Evaluation of input factors 
• Actuation of components 

Reading in of sensors and signals 

The input factors are read in with the following connections:

• Direct line 
• Interior CAN 

Direct line 

The signals from the following components are read via a direct line:

• Trunk lid position sensor (B24/16)
• TLC [HDS] button (S62/26)

Interior CAN 

The following information is read in via the interior CAN:

• by the left door control unit (N69/1) (model 216) or left front door control unit (N69/1) (model 221):
  • Status trunk lid open/close switch (S20/1s6)
• by the rear SAM control unit with fuse and relay module (N10/2):
  • Trunk lid CL motor status (M14/7)
  • Status of trunk lid emergency opening switch (S88/10) (with code (494) USA version)
  • Rear window antenna amplifier module (A2/12)
• by the instrument cluster (A1):
  • Vehicle speed
• by the COMAND control unit (A40/3) via the central gateway control unit (N93):
  • Garage position status

Evaluation of input factors 

The input factors that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.

Actuation of components 

The following components are actuated with a direct line:

• TLC hydraulic pump (M51)
