Embodiments of the present invention relate to the field of automobile diagnosis technologies, and disclose a remote automobile diagnostic method and apparatus, a mobile terminal, an electronic device and a server. A controlled end of remote automobile diagnosis may automatically generate protocol data and send the protocol data to a controlling end; or the controlling end of the remote automobile diagnosis may parse the protocol data, generate an interface associated with a user interface of the controlled end, then receive an interface operation instruction, and generate action data according to the interface operation instruction and send the action data to the controlled end. In this way, a local diagnosis function is added to the controlling end, so that a remote diagnosis function is implemented accordingly, which has favorable scalability.
