Electronic Ignition Lock Control Unit, Component Description - GF80.57-P-6001RR
Model 190
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 of the transmitter key (A8/1) and data exchange with the transmitter key
Reading in of signals
The input factors are read in via the following connections:
- Direct line
- Interior CAN (CAN B)
- Chassis CAN 1 (CAN E1)
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 that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Chassis CAN 1
The signals are read in by the electronic ignition lock control unit via the chassis CAN 1.
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Evaluation of input factors
The input factors read in are evaluated by the integrated microprocessor whereupon the relevant signals are then issued.
Output of signals
The signals are issued over the following connections:
- Interior CAN
- Chassis CAN 1
Interior CAN
The signals are transmitted to the electronic ignition lock control unit via the interior CAN.
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Chassis CAN 1
The signals are transmitted to the electronic ignition lock control unit via the chassis CAN 1.
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Power supply of transmitter key and data exchange with 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. Encrypted data is exchanged via infrared signals between the transmitter key and the electronic ignition lock control unit for identification of the transmitter key.
