The EDC control unit is the control unit for the Vertical Dynamics Management system. The EDC control unit is connected via the wiring harness and the shock absorber wiring harness to the EDC valves on the shock absorbers and to the vertical acceleration sensors (not M GmbH). The shock absorber wiring harness can be replaced separately (shock absorber wiring harness comprises twin-core sheathed wiring).

The EDC valves are activated by 4 output stages in the EDC control unit.

The Electronic Damper Control is activated under the following conditions:

Ignition on (terminal 15).
Speed greater than approx. 3 km/h
