- Incorrect Readings: Confirm that the vehicle's parameters (e.g., engine size, fuel type) are correctly entered in the ScanGauge settings. Some readings are vehicle-dependent.
- Difficulty Connecting: Ensure your vehicle is OBD2 compliant (1996 or newer). If issues persist, try disconnecting and reconnecting the unit.
- "Check Engine" Light Remains On: After clearing DTCs, if the "Check Engine" light reappears, the underlying issue has likely not been resolved. Further diagnosis and repair may be necessary.
