The OBDSTAR N004 is a connector adapter that converts a 3-pin OBD connection into a 16-pin OBD2 (J1962) port. On the vehicle side, the adapter connects directly to the proprietary 3-pin diagnostic connector found on scooters and motorcycles.

Different two-wheeler manufacturers use their own 3-pin diagnostic connector. The adapter routes the relevant signal pins to the correct positions on the OBD2 port, allowing your diagnostic scanner to establish a K-line- or CAN-bus-connection with the vehicle. The compact housing enables direct mounting on the vehicle connector without additional wiring.

The adapter provides access to the two-wheeler's engine control unit and nothing beyond. Compatibility varies by model year and available diagnostic port; what functions you can perform depends on your OBDSTAR device's software.

KEY BENEFITS

✔No loose cables — the adapter connects the 3-pin vehicle connector directly to the OBD2 port.
✔Seven brands — compatible with two-wheelers from Aprilia, Ducati, Honda, KTM, Piaggio, Vespa, and Yamaha equipped with this connector type.
✔Compact design — the adapter sits flush on the diagnostic port and takes up minimal space in your vehicle.
✔K-line and CAN-bus — both vehicle communication protocols are passed through to your diagnostic tool.

IMPORTANT NOTES

✕Not all models within a brand — compatibility depends on model year and the diagnostic port present; a brand being listed is not a guarantee for every model.
✕Two-wheelers only — cars and commercial vehicles are outside the scope of this adapter.
✕OBDSTAR devices only — the adapter is not compatible with diagnostic systems from other manufacturers.
✕No additional coverage — available systems and functions are determined by your OBDSTAR device's software.

Applications and Features

Access your scooter or motorcycle's control unit through the 3-pin connector.

Control units you can reach

  • Electronic control unit: the engine control module of your scooter or motorcycle behind the 3-pin diagnostic connector.
  • Other modules: whether additional systems are accessible varies by brand, model, and device.

What you can do

  • Read fault codes: retrieve stored diagnostic trouble codes (DTCs) from your two-wheeler's electronic control unit.
  • Clear fault codes: erase fault status and trouble codes from the system after diagnosis and repair.
  • Request live data: read real-time sensor values and engine parameters via K-line or CAN connection.
  • Convert connection: the 3-pin vehicle interface is mechanically and electrically adapted to the 16-pin OBD2 J1962 connector.
  • Important: not every model within a supported brand is guaranteed to be accessible; this depends on year of manufacture, diagnostic port type, and device.
