Interference Suppression Measures
All standard and optional electrical consumers in the vehicle are shielded.
Interference suppression includes all sensors, actuators and all electrical motors in the vehicle, as well as controllers in control modules that could
cause high-frequency interference.
For interference suppression, electrical parts capacitors, coils and diodes are installed directly in the electrical components.
Interference suppression components are also built into the connection housings of electrical consumers.
The grounding cables that used to be employed for shielding purposes are no longer used because interference suppression is now done as near as
possible to the source of the interference.
