ノイドの診断装置。 A device for diagnosing the quality of a solenoid in a solenoid control device in which a current control device superimposes a direct current control current and a dither current that reverses at a predetermined period and supplies the same to the solenoid to drive the solenoid, and detects the driving voltage of the solenoid. A solenoid drive voltage detected a predetermined time after the dither current rises when a voltage detection means is provided and the solenoid is driven by setting the solenoid drive power supply voltage and DC control current to reference values. What is claimed is: 1. A solenoid diagnostic device comprising a determining means for determining whether a solenoid is good or bad based on the above.
