The solenoid valve is not activated even after ASC-ECU has turned on the valve relay (Open circuit is present in the solenoid valve circuit in ASC-ECU, or the valve relay has failed). 3). After ASC-ECU has turned off the driving transistor, the solenoid valve still remains energized (short in the solenoid valve circuit). 4). When a solenoid valve failure is detected.
