DTC 22
ECU sends a signal to suspension control actuator to drive the rotary valve of the shock absorber changing the shock absorber damping force. A suspension control actuator is fitted to each pneumatic cylinder.
The actuator is driven electromagnetically by step motor so that it can accurately follow the driving conditions that change frequently.
Code 22 corresponds to the front LH suspension control actuator circuit.
Once the ECU stores diagnostic trouble code 22 in memory, damping force is not carried out until a normal signal is input to the ECU from the suspension control actuator. However, control is resumed if the ignition switch is turned off, then on again.
