GF80.20-P-6082CE Liftgate Control Unit, Component Description
- with CODE (890) EASY-PACK liftgate

Component Identification:

Location
The liftgate control unit is fastened in the area of the upper left D-pillar on the headliner.

Task
The liftgate control unit has the following purposes:
^ Reading in of sensors, pickups and signals
^ Evaluation of input factors
^ Actuation of components

Reading in of sensors, pickups and signals
The input factors are read in with the following connections:
^ Direct line
^ Interior CAN (CAN B)

Direct line
The signals from the following components are read via a direct line:
- Liftgate control Hall sensor (M51/3b1)
- Liftgate control position sensor (M51/3b2)
- Additionally for model 204.9:
- Left tailgate control obstruction sensor strip (B86/1)
- Right tailgate control obstruction sensor strip (B86/2)

Interior CAN
The following signals are read in over the interior CAN:
Left front door control unit (N69/1):
- Status of driver liftgate control button (S15/3)

by the rear SAM control unit with fuse and relay module (N10/2):
- Status of liftgate rotary tumbler switch (M14/7s1)
- Status of liftgate control button (S62/36)
- Status of liftgate external operation switch (S88/8)
- Access authorization code for transmitter key (A8/1) via rear window antenna amplifier 1 (A2/71)

From the instrument cluster (A1):
- Vehicle speed signal

by the electronic ignition switch control unit (N73):
- Terminal status 15

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

Actuation of components
The actuation of the components takes place via the following connections:
- Direct line
- Interior CAN

Direct line
The following components are actuated with a direct line:
- Liftgate control warning buzzer (H4/60)
- Liftgate control electric motor (M51/3m1)
- Liftgate control magnetic clutch (M51/3y1)

Interior CAN
The following component is actuated via the interior CAN: By the rear SAM control unit:
- Liftgate locking element (M14/31)
