GF80.61-P-4204FL Keyless-Go Control Unit, Component Description
- with CODE (889) Keyless Go

Component Identification:

Location
The KEYLESS-GO control unit is located behind the right paneling in the trunk.

Task
The Keyless-Go control unit has the following purposes:
^ Reading in of sensors
^ Evaluation of input factors
^ Actuation of components

Reading in of sensors
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:
- Left front KEYLESS GO door handle (A17/1)
- Right front KEYLESS GO door handle (A17/2)
- Left rear KEYLESS GO door handle (A17/3)
- Right rear KEYLESS GO door handle (A17/4)
- FM 1, AM, CL and KEYLESS-GO antenna amplifier (A2/18)

Interior CAN
The signals are read in by the KEYLESS-GO control unit via the interior CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).

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.
