MODEL 204.3
MODEL 204.9
Shown on model 204.0
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
- Actuating components
- Power supply for transmitter key (A8/1)
- Interface to KEYLESS-GO control unit (N69/5) (with code (889) Keyless-Go)
Reading in of signals
The input factors are read in via the following connections:
- Direct line
- Interior CAN (CAN B)
- Chassis CAN (CAN E)
Direct line
The electronic ignition lock control unit communicates with the electronic ignition lock control unit (N26/5) via a bi-directional serial data line.
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.
Controlling functions
The electronic ignition lock control unit controls the following functions:
- Central locking (CL [ZV])
- Convenience feature (CF)
- Drive authorization system, stage 3 (DAS 3)
- Shiftlock function (with transmission 722)
- Encrypted data exchange according to hash method for key identification
- Rotation-angle dependent activation of individual circuits (circuit 15C, circuit 15R, circuit 15, circuit 15X and circuit 50)
Component actuation
The actuation of the components takes place via the following connections:
- Direct line
- Interior CAN
- Chassis CAN
Direct line
The electronic ignition lock control unit communicates with the electronic ignition lock control unit via a bi-directional serial data line.
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.
Interface to KEYLESS-GO control unit (with code (889) Keyless Go)
- Interface to Keyless-Go control module via interior CAN for Keyless-Go access and Keyless-Go operation
- Mechanical sensing and read-in of KEYLESS-GO start/stop button (S2/3) for the Keyless Go operation
