Hyundai Genesis (DH): ECS(Electronic Control Suspension) System / Description and Operation

Hyundai Genesis (DH) 2013-2016 Service Manual / Suspension System / ECS(Electronic Control Suspension) System / Description and Operation

Description
Real-time continuous control of the damping force according to vehicle running conditions and the state of road surface will enhance ride comfort and steering safety, including roll/pitch reduction in case of vehicle dynamics control, quick turning, braking, and starting.
Continuously Variable Damper
Damping force variable solenoid valve current will be controlled by ECU. Depending on change in the current amount, , the spool valve will move in the actuator to change flowing route and lead to the damping force variation.
