Claim 16:
17. The electrical control device detection method according to claim 16, wherein a method for determining whether a shorted-to-power-supply fault occurs in the drive circuit of the electrical control device is:
obtaining a third electrical signal at the second end of the second detection module when both the first switch module and the second switch module are in an off state;
determining whether a level of the third electrical signal is the first level;
determining, if a determining result is that the level of the third electrical signal is the first level, that a shorted-to-power-supply fault occurs in the drive circuit of the electrical control device; or
determining, if a determining result is that the level of the third electrical signal is not the first level, that no shorted-to-power-supply fault occurs in the drive circuit of the electrical control device.
