DTC C1723 Damping Force Control Actuator Circuit

CIRCUIT DESCRIPTION
ECU sends a signal to damping force control actuator to drive the rotary valve of the shock absorber changing the shock absorber damping force. A damping force control actuator is fitted to each damping force control actuator.
The actuator is driven electromagnetically by step motor so that it can accurately follow the driving conditions that change frequently.





DETECTING CONDITION

HINT:
- Code C1721/21 corresponds to the front damping force control actuator circuit.
- Code C1723/23 corresponds to the rear damping force control actuator circuit.

Fail safe function:
If trouble occurs in the front or rear wheel damping force control actuator circuit, ECU prohibits the damping force control after the ECU has returned the damping force of the other side wheel to the normal condition.
