A vehicle diagnostics technology is provided. Further, a vehicle fault diagnostic method, an on-board diagnostic apparatus, and a related system that are used for advanced intelligent driving are provided. Fault diagnosis is separately performed at nodes at a plurality of levels. An upper-level node is configured to converge and control a lower-level node. At the upper-level node, fault information at a level at which the upper-level node is located is diagnosed, and fault information of the lower-level node is diagnosed. The lower-level node not only sends the fault information to the upper-level node, but also can communicate with a master computer through a communication interface. Different faults can be isolated through hierarchical diagnosis. In addition, an upper-level node handles a problem of a lower-level node to perform targeted repair. This significantly improves a fault diagnostic capability of a complex system in a vehicle.
