N26/5 ELV control unit

Location
The ELV control module is located on the steering column.

Task
- Input of signals from the EIS [EZS] control unit (N73) via a discrete line
- Acknowledgement and fault message feedback to EIS [EZS] control unit.
- Control of locking motor with catch bolt.

Before it can be used properly it is necessary to learn in the ELV control unit on the EIS [EZS] control unit with the aid of Xentry diagnostics

Lock
Function requirements:
- Status "Circuit 15C OFF" is recognized.
- Vehicle stops.

The ELV control unit reads in the "Lock ELV" signal from the EIS [EZS] control unit. The electronic control circuitry integrated in to the ELV control unit evaluates this signal and actuates the locking motor with catch bolt, locking the steering column.
Simultaneously an acknowledgement or fault message is returned to the EIS [EZS] control unit.

Release
Function requirements:
- "Circuit 15C ON" is recognized
- The transmitter key (A8/1) is recognized by the EIS [EZS] control unit.

The ELV control unit reads in the "Unlock ELV" signal from the EIS [EZS] control unit. The electronic control circuitry integrated in to the ELV control unit evaluates this signal and actuates the locking motor with catch bolt, unlocking the steering column. Simultaneously an acknowledgement or fault message is returned to the EIS [EZS] control unit.

Operating safety
The steering column is prevented from locking while driving by interrupting the power supply to the ELV control unit.

Design
The ELV control unit comprises the following components:
- Electronic control
- Locking motor with catch bolt
