The present disclosure discloses a fault detection method and device. The method includes: receiving, by a terminal device, a fault detection instruction entered by a user, and determining a service type of a to-be-detected fault according to the fault detection instruction; determining fault detection content according to the service type; starting to detect the fault detection content to obtain a detection result; and presenting the detection result. In this way, whether in a period of deploying or in a period of using the terminal device, the fault detection instruction is directly triggered when there is a need to determine whether the terminal device is faulty, and then the fault detection content corresponding to the service type of the to-be-detected fault is detected, which effectively implements a self-detection capability of the terminal device, increases a fault locating speed, and improves fault detection accuracy. |
