General
The electronic ignition lock control unit is connected to the network architecture of the vehicle and forms an interface for the communication of different systems and their control units. In addition, the electronic ignition lock control unit transmits information for the variant coding, e.g. model series, major assembly version, and national version, via the network architecture of the vehicle to all control units. They then perform part of their self-configuration.
Function
The electronic ignition lock control unit actuates the following functions:
- Central locking
- Drive authorization system
- KEYLESS-GO Start (except model 293)
- KEYLESS-GO (vehicles with KEYLESS-GO, except model 293)
- Steering lock (vehicles with manual transmission)
- Emergency path actuation for engaging transmission position P in the case of undervoltage (vehicles with automatic transmission)
In order to implement the functions, the electronic ignition lock control unit processes the following information:
- Signals from the transmitter key or the "Digital Vehicle Key on the Smartphone" (vehicles with vehicle access and drive authorization via mobile phone)
- Signals from the KEYLESS-GO antennae
- Signals from the sensors in the door handles (vehicles with KEYLESS-GO)
- Status of left front door (open/closed)
- Status of start/stop button
The electronic ignition lock control unit processes this information and transmits the following information and requests via the network architecture:
- Circuit status
- Central locking status
- Request to lock/unlock central locking system
- Request for the access authorization code for the drive authorization system
- Steering lock requirement (vehicles with manual transmission)
- Request to engage drive range P (vehicles with automatic transmission)
