MODEL 204.0/2 with CODE (889) KEYLESS-GO as of model year 2009/YoM 08
MODEL 204.3 with CODE (889) KEYLESS-GO.
MODEL 204.9 with CODE (889) KEYLESS-GO.
Shown on model 204.0
Location
On model 204.0/2/3 the KEYLESS-GO control unit is located behind the right paneling in the trunk. On model 204.9, the KEYLESS-GO control unit is located on the base carrier in the trunk.
Task
The KEYLESS-GO control unit has the following purposes:
- Reading in of sensors, pickups and signals
- Evaluation of input factors
- Actuating components
Reading in of sensors, pickups and signals
The input factors are read in via 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 door KEYLESS GO door handle (A17/3) (on model 204.0/2/9)
- Right rear KEYLESS GO door handle (A17/4) (on model 204.0/2/9)
- TV 2 and KEYLESS-GO antenna amplifier (A94/2) (model 204.0/3/9)
- KEYLESS GO antenna amplifier (A94/4) (model 204.2)
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.
Component actuation
Components are actuated with the following lines:
- Direct line
- Interior CAN
Direct line
The following components are actuated via a direct line:
- trunk KEYLESS-GO antenna (A2/35)
- Left door KEYLESS-GO antenna (A2/38) (model 204.3)
- Left rear door KEYLESS GO antenna (A2/39) (model 204.0/2/9)
- Right door KEYLESS-GO antenna (A2/40) (model 204.3)
- Right rear door KEYLESS GO antenna (A2/41) (model 204.0/2/9)
- interior KEYLESS-GO antenna (A2/61)
- Additional on vehicles up to 2.12.09:
- Left front door opening assist motor (A85m2)
- Right front door opening assist motor (A85/1m2)
- Left rear door opening assist motor (A85/3m2)
- Right rear door opening assist motor (A85/4m2)
Interior CAN
The signals are transmitted 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).
