Claim 13:
14. The electrical control device detection method according to claim 13, wherein, the obtaining an electrical signal at a third end of a first detection module and an electrical signal at a second end of a second detection module, and determining, based on the electrical signal at the third end of the first detection module and 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:
closing a first switch module when a low-side switch unit is in a disabled state;
obtaining a first electrical signal at the second end of the second detection module; and
closing a second switch module when it is determined that a level of the first electrical signal is not a preset first level, and obtaining a second electrical signal at the third end of the first detection module; and
determining a fault type of the drive circuit of the electrical control device based on the second electrical signal.
