Description of activations

General

The hydraulic valves and the pump motor can be activated. The valves and the pump motor are activated and deactivated for approximately 4 seconds. The brake systems can be equipped with different functions, for example traction control and stability functions. This means that not all components can necessarily be activated for the control module in question.
