The vehicle remote diagnostics (VRD) system is a set of devices for remote electronic diagnostics of vehicles: trucks, cars and specialized vehicles (hereinafter collectively referred to as vehicles). The VRD system includes VRD-Server, VRD-Client mobile device and VRD Control software. For diagnostics, a diagnostic tool (communication interface, hereinafter referred to as the VCI, and dedicated software compatible with the diagnosed vehicle) is additionally used.

The system transfers diagnostic data between VRD-Client connected to the vehicle and VRD-Server connected to VCI. Data is transferred via Wi-Fi or mobile networks (through Internet). This allows a vehicle to be diagnosed remotely: the diagnostic technician and the diagnosed vehicle may stand at a distance from each other.

The VRD system is used to check errors that have occurred, correct faults or adjust parameters of the vehicle.

The VRD system is configured and controlled using VDR Control software.

VRD-Server supports data reading and transmission via main OBD interfaces:

  • Two CAN-buses that support CAN 2.0B (125, 250, 500, 1000 Kb/S)
  • Eight K-lines (ISO 14230, ISO 9141)
  • J1708 interface
  • Transmits vehicle ignition status (if such a functionality is supported by the vehicle)

VRD- Server is fed from power supply unit (12 or 24 V) and transmits power to VCI. Input voltage range: 12 to 36 V, power consumption abt. 0.1 A.
