Vehicle diagnostics system and method therein for enabling synchronous remote vehicle diagnostics for a plurality of vehicles
A method performed by a vehicle diagnostics system for enabling synchronous remote vehicle diagnostics for a plurality of vehicles is provided. The vehicle diagnostics system obtains information indicating that an application in the vehicle diagnostics system is requesting to perform synchronous remote vehicle diagnostics on a selected vehicle among the plurality of vehicles. The vehicle diagnostics system also determines, by using an Application Programming Interface, API, available in the vehicle diagnostics system, a logical network location of an on-board connectivity device, OCD, integrated in an on-board network of the selected vehicle. Further, the vehicle diagnostics system establishes, using the API, a logical network connection between the determined logical network location of the OCD and the logical network location of the vehicle diagnostics system over a wireless communications network.
