DTC 22

CIRCUIT DESCRIPTION:
Codes 21, 22, 23 and/or 24 will be set if there is an open or short circuit in the suspension control actuator circuit. Inspect the ECU, suspension control actuator ad the harness/connectors between them.
ECU sends a signal to the 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 a step motor so that it can accurately follow the driving conditions that change frequently.
Once the ECU stores DTC 21, 22, 23 or 24 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.

^ Code 21 corresponds to the front RH suspension control actuator circuit.
^ Code 22 corresponds to the front LH suspension control actuator circuit.
^ Code 23 corresponds to the rear RH suspension control actuator circuit.
^ Code 24 corresponds to the rear LH suspension control actuator circuit.

INSPECTION PROCEDURE
^ When DTC 21 is displayed, check the front RH suspension control actuator circuit.
^ When DTC 22 is displayed, check the front LH suspension control actuator circuit.
^ When DTC 23 is displayed, check the rear RH suspension control actuator circuit.
^ When DTC 24 is displayed, check the rear LH suspension control actuator circuit.
^ When DTC 21, 22, 23 or 24 displayed, perform inspection step 2 (in the illustration).
