Component description for the electronic ignition switch control unit - GF80.57-P-6001RQ
MODEL 197
Shown on model 197.3
Location
The electronic ignition lock control unit is located in the rear section of the center console.
Task
The electronic ignition lock control unit has the following tasks:
- Reading in of signals
- Evaluation of input factors
- Output of signals
- Power supply for transmitter key (A8/1)
Reading in of signals
The input factors are read in with the following connections:
- Direct line
- Interior CAN (CAN B)
- Chassis CAN (CAN E)
Direct line
The following signal is read in via a direct line:
- Status of left door lock (A85)
Interior CAN
The signals are read in by the electronic ignition lock control unit via the interior CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Chassis CAN
The signals are read in by the electronic ignition lock control unit via the chassis 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.
Output of signals
Components are actuated with the following lines:
- Interior CAN
- Chassis CAN
Interior CAN
The signals are transmitted to the electronic ignition lock control unit via the interior CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Chassis CAN
The signals are transmitted to the electronic ignition lock control unit via the chassis CAN.
The functions resulting therefrom are described in the corresponding function descriptions (see block diagram or function schematic).
Power supply for transmitter key
When the transmitter key is inserted into the electronic ignition lock control unit, it switches on the inductive power transmission for power supply to the transmitter key.
