Wireless Diagnostic Interface WDI-2

Our WDI-2 is the successor of the known WDI (Wireless Diagnostic Interface), a universally applicable, mobile diagnostic interface used in development, production and workshops. The compact device establishes the communication between the ECUs of a vehicle and an external, PC-based diagnostic application. For that purpose, the WDI-2 is plugged to the vehicle’s OBD connector and contacts the test computer alternatively via WLAN or tethered. If requested, the WDI-2 is also available with Bluetooth.

Software and hardware of the WDI-2 support all current vehicle buses and diagnostic protocols as well as the D-PDU-API standard/PRODIS.PDU (ISO 22900-2):

  • UDS on CAN
  • OBD on CAN und K line
  • KWP2000 on ISO-TP, TP2.0, TP1.6 and K line
  • KW1281 on TP1.6 and K line
  • SAE J1939
  • DoIP


Vehicle-specific OBD head

The OBD plug of the WDI-2 can be designed customer-specifically and therefore enables the adaptation to the requirements of the electronic vehicle architecture.


  • Compact design (84 x 59 x 22 mm without OBD head)
  • Light weight (80g)
  • Robust housing, designed for industrial use; protected against splash water according to IP54
  • Ease of use

  • MVCI-compatible
  • Interactive configuration of the device using the DSA VCI Manager
  • Parallel diagnostic processes with arbitrary combination of protocols and bus systems
  • Full integration into our PRODIS tool suite
