The ECU sends a signal to the damping force control actuator to drive the rotary valve of the shock absorber changing the shock absorber damping force.

The actuator is driven electromagnetically by a step motor so that it can accurately follow the driving conditions that change frequently.

The suspension control ECU receives signals from the yaw rate sensor via CAN communication.

This circuit is used for sending the data to detect the fluid temperature of the pump. The abnormality of the fluid is judged by the ECU.

The suspension control ECU receives signals from the steering control ECU via CAN communication.

This circuit is used for sending the data to detect the pressure output from the pump. The abnormality of the fluid pressure is judged by the ECU.

The steering sensor signal is sent to the suspension control ECU through the CAN communication system. When there is a communication malfunction, it will be detected by the diagnosis function.

The speed sensors monitor the speed of the wheels, and send appropriate speed signals to the suspension control ECU through the skid control ECU. If trouble occurs in either the front speed sensor or rear speed sensor, DTC (C1783) is output.

Connect the intelligent tester to the DLC3.

Clear the DTCs ().

In case that the height control has not finished in spite of performing the raise control for a certain period of time, the ECU interrupts the height control.
