Component description for the electronic ignition lock control unit - GF80.57-P-6001FQ
MODEL 218
Location
The electronic ignition lock control unit is located on the right, next to the steering column.
Task
The electronic ignition lock control unit has the following tasks:
- Reading in of signals
- Evaluation of input factors
- Controlling functions
- Output of signals
- Power supply for transmitter key (A8/1)
Reading in of signals
The input factors are read in via the following connections:
- Direct line
- Interior CAN (CAN B)
- Chassis CAN (CAN E) (up to 28.02.2013)
- Chassis CAN 1 (CAN E1) (as of 01.03.2013)
Direct line
The electronic ignition lock control unit reads in the status of the left front door rotary tumbler switch (A85s1) in the left front door lock (A85) via a direct line.
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 (up to 28.02.2013)
The signals are read in by the electronic ignition lock control unit via the chassis CAN.
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Chassis CAN 1 (as of 01.03.2013)
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 that have been read in are evaluated by the integrated microprocessor and the relevant components are then actuated.
Controlling functions
The electronic ignition lock control unit actuates the following functions:
- Central locking (ZV)
- Convenience feature (CF)
- Drive authorization system stage 3 (DAS 3) (up to 31.08.2014)
- Drive authorization system stage 4 (DAS 4) (as of 01.09.2014)
Output of signals
The actuation of the components takes place via the following connections:
- Interior CAN
- Chassis CAN (up to 28.02.2013)
- Chassis CAN 1 (as of 01.03.2013)
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 (up to 28.02.2013)
The signals are transmitted to the electronic ignition lock control unit via the chassis CAN.
The functions that use these signals are described in the individual function descriptions (see block diagram or function schematic).
Chassis CAN 1 (as of 01.03.2013)
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 for transmitter key
When the transmitter key is inserted into the electronic ignition lock control unit, the electronic ignition lock control unit 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.
