Location
The electric steering lock control unit is located the steering column
Task
The electric steering lock control unit processes information from the EIS control unit (N73) and is connected with it via a bi-directional, serial data line
After the unlocking operation, the power to the locking components is switched off to avoid unintentional locking
Purpose, electronic stage
- Calculation of Hash value
- If the Hash value is incorrect and the unlocking position is not reached or not recognized, an error message is transmitted to the EIS control unit.
- Position monitoring of locking bolt via 2 Hall sensors
- Switching on integrated motor via alternating relay for locking and unlocking locking bolt
Purpose, mechanical stage
- Arresting steering column with locking bolt
Discrete inputs
- Circuit 30
- Tml. 31
- Serial data line to EIS control unit
Discrete outputs
- Serial data line to EIS control unit
