Claim 17:
18. The electrical control device detection method according to claim 13, wherein the “obtaining an electrical signal at a second end of a second detection module, and determining, based on the electrical signal at the second end of the second detection module, whether a fault occurs in a drive circuit of the electrical control device” specifically comprises:
enabling a low-side switch unit when a first switch module is in a closed state;
obtaining a fourth electrical signal at the second end of the second detection module; and
determining whether a level of the fourth electrical signal is a preset second level;
determining, if a determining result is that the level of the fourth electrical signal is the preset second level, that the low-side switch unit is enabled normally; or
determining, if a determining result is that the level of the fourth electrical signal is not the preset second level, that the low-side switch unit is enabled abnormally.
