An error detecting method of the solenoid valve is provided that the risk of operator is prevented since the malfunction of the solenoid valve is detected before the car control system operates. An error detecting method of the solenoid valve comprises following steps: a step(100) that determines whether the relay connected to the solenoid valve was switched with the battery power or not; a step(110) that whether is the situation which compulsorily operates the solenoid valve or not determines; a step(120) for performing the fault detection of the solenoid valve; a step(130) that the solenoid valve is on-operated the constant for hour force and determining as the failed state if the short occurs in the solenoid coil; a step(140) that the solenoid valve is run the forcing off and determining as the failed state if the solenoid valve is opened; a step(190) that the warning lamp is lit if the solenoid valve is determined as the failed state and informs operator. |
