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. Components
The adaptive damper system consists of the following primary components:
For locations of each component on vehicle, refer to Component Location Index, and for functions of system warning, refer to How to Troubleshoot the Adaptive Damper System. 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. In the integrated drive-mode system is in SPORT mode, the adaptive damper adjusts the damping force higher than NORMAL mode. Adaptive Damper Characteristic Image
Integrated Drive-Mode System
The adaptive damper system has two control modes which correspond to the integrated drive-mode signal sent from the PCM via F-CAN. When the integrated drive-mode system in NORMAL mode, the adaptive damper system provides a float ride. When the integrated drive-mode system in SPORT mode, the adaptive damper system provides a flat ride. 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.
