GF80.20-P-2006SX Closing Trunk Lid, Function
- with CODE (881) Remote trunk closing (RTC [HDFS])

Component Identification:

The trunk lid can also be closed by hand. In this case, it is necessary to overcome the resistance of the hydraulic drive.

Function requirements
^ Normalize trunk lid
^ No overvoltage/undervoltage
^ Vehicle stationary

Function
The trunk lid can be closed using the following 2 controls. Actuation differs only up to the time the request is present at the TLC control unit.

1.1 Trunk lid open/close switch
When the trunk lid open/close switch is actuated and held down, the "Open" signal is read in by the corresponding door control unit via front door LIN.

The door control unit relays it to the TLC control unit via interior CAN.
When the trunk open/close switch is released, the closing procedure is stopped.

1.2 TCL button
The TCL button is read in directly by the TLC control unit. Momentary actuation is sufficient.

Vehicles with code (889) Keyless Go:
The TCL button is designed as two-piece version.When the left button is actuated, the trunk lid is closed, when the right button is actuated, the vehicle is locked.
The Keyless Go control unit initiates a check of the transmitter key (A8/1) (N69/5); validity of the transmitter key is checked by the EIS control unit.Locking is only accomplished, if a valid transmitter key is recognized outside of the vehicle.

2 Close trunk lid
The TLC control unit actuates the TLC hydraulic pump as long as the trunk lid rotary tumbler microswitch (M14/7s3) signals "Trunk lid closed" to the SAM control unit.

The closing procedure of the trunk lid is monitored via the trunk lid position sensor by the TLC control unit.
Then the trunk lid is completely closed with power closing via the trunk lid CL motor.
