OBD-II
Vehicle diagnostic standard present in all modern cars since 1996.
OBD-II (On-Board Diagnostics II) is a vehicle diagnostic standard mandatory in all cars sold in the United States since 1996 and globally adopted. It defines a standard connector and communication protocols for accessing vehicle data.
OBD-II Port
The OBD-II connector is a 16-pin port usually located under the driver's dashboard. Through this port, Rinho devices can read ECU data without modifications or cable cutting.
Data accessible via OBD-II
- Engine RPM
- Vehicle speed
- Fuel level
- Coolant temperature
- Throttle position
- Error codes (DTC)
- Engine status (on/off)
- VIN (vehicle identification number)
OBD-II in Rinho devices
Spider IoT and Smart IoT devices connect to the OBD-II port natively to read this data. The connection is plug-and-play: no vehicle-specific programming is required in most cases. OBD-II is one of the protocols supported by Rinho's built-in CAN Bus reading.
