GF80.20-P-6000LE TLC Control Unit, Component Description
- with CODE (881) Remote trunk closing (RTC [HDFS])

Component Identification:

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 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)
