Activation and setpoint values
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
Vehicle voltage is supplied to the engine control. The engine control contains a DC/DC converter that steps up the voltage required for activation of the injector. The injector is activated by the engine control on the ground side.
