Shock Absorber Actuators
WARNING: This page is about a different car, the 2016 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
The shock absorber actuators are integrated within the shock absorbers. The electronic suspension control system uses a proportional valve that is located in the external bypass of the displacement module.
Adjustment is performed by current control. The current range is 0-5 A. The actuators respond to commands of the suspension control module within milliseconds.
