The ECS is the abbreviation for "Electronic Control Suspension". This ECS system automatically controls the height of a vehicle level and the damping force of shock absorbers according to road condition. So it improves riding comfort and steering stability. Among components of the ECS system, the ECS damper is installed at the four-corner of the vehicle and controls the orifice of the shock absorber according to the road condition. That is, the ECS ECU receives various sensors' signals with driving and it estimates the current road condition and then, it controls a damping force of a shock absorber by a damper.
The ECS ECU checks the ECS damper for a normal operation and if it is detected as a open or short circuit, this DTC is set.
