    Remote diagnostics devices

    Description of one of the available methods for performing remote diagnostics

    The Remote Vehicle Interface Module (r-VIM) device is designed to provide access to the diagnostic connectors of the tested vehicle using programs that are installed on a remote computer. r-VIM device is to be accessed over the Internet by either using a local Wi-Fi network (a password needs to be entered or a QSS button pressed on a router) or a built-in 4G modem.

    Supply voltage is brought to the “12V” connector on the front panel of the device either from the AC / DC adapter or from the Power Bank through a DC / DC converter or from the car cigarette lighter. To diagnose OBD-II / EOBD / JOBD systems, the device is connected to the vehicle through the diagnostic connector, known as the OBD-II connector using the Mongoose MFC Drewtech cable or Tactrix OpenPort 2.0 cable, which should be connected to the USB input of the r-VIM device.

    To diagnose and collect data from electronic systems of electric vehicles (Toyota RAV4EV Tesla Electric Propulsion Control System for example) a standard network cable with LAN (RJ45) is used; one end of the cable is plugged in the connector on the rear panel of the r-VIM, the other end should be connected to the diagnostic connector (i.e. DLC3 No. 2 as Toyota calls it).

    When cable and the Internet connections are successfully completed the device communicates with the base server and, after turning on the car ignition, corresponding diagnostic programs are launched on the remote computer. With their help all vital systems are checked and the log files of parameters are created. All the information is analyzed and appropriate recommendations for troubleshooting are developed. “Technical support/ advice” for subsequent repairs is provided.

    Complete set of the device is mailed to the requested location by courier. It’s for temporary use only and has to be returned.
