Adaptive Damper System Description
Overview
The adaptive damper system provides optimal damping force for all driving conditions by adjusting the damping force of each damper independently, improving the driving performance.The system is controlled by the adaptive damper control unit.With the adaptive damper system, roll-, pitch-, and yaw- motion of the vehicle can be controlled resulting in different driving characteristics.The adaptive damper control unit controls each damper solenoid with vehicle motion signals from other control units.
Control
The adaptive damper adjusts the damping force as in the following graph, depending on the change of the amount of electric current output from the adaptive damper control unit.

Integrated Dynamics System
The damping force control is changed by the integrated dynamics system mode shown below. When the integrated dynamics system is in the INDIVIDUAL mode, the adaptive damper system can be customized separately by the INDIVIDUAL settings (Adaptive damper system is included in Suspension setting).
| Adaptive Damper System | Integrated Dynamics System Mode | |||
|---|---|---|---|---|
| COMFORT | NORMAL | SPORT | SPORT+* | |
| Damping Force | Soft | Medium | Firm | |

Fail Safe Mode
Depending on the severity of the error, the adaptive damper system will switch to one of four possible fail safe modes. In case of each fail safe mode a DTC is stored in the adaptive damper control unit.
| Fail Safe Mode | Failure State | Action | Failure Indication |
|---|---|---|---|
| A |
|
The current for all dampers are switched off. | ON |
| B |
|
A fixed current (0 A or 0.4 A) is set for all dampers. | ON |
| C |
|
A fixed current (0 A or 0.4 A) is set for all dampers. | OFF |
| D |
|
The control mode is fixed in the mode when the failure occurred. | OFF |
