| OBD type | Launch time | Main features |
|---|---|---|
| OBD-I | 1980s | Manufacturer-specific, no unified standard |
| OBD-II | 1996 (USA) | Standardized interface supports universal diagnostics |
2. How to use OBD?
Using OBD requires the following steps:
1.Positioning interface: Usually located under the steering wheel, the common shape is a 16-pin trapezoid.
2.Select device: Choose a basic scanner or smart OBD device according to your needs.
3.Connect devices: Insert the OBD device into the interface. Some devices require Bluetooth/WiFi pairing.
4.Read data: View vehicle information through the supporting APP or software.
| OBD function | Applicable scenarios | Typical data |
|---|---|---|
| Troubleshooting | Maintenance inspection | DTC |
| Real-time monitoring | daily driving | Speed, fuel consumption, water temperature |
| Performance analysis | Modification optimization | Air-fuel ratio, turbine pressure |
