Maintenance

To ensure the longevity and optimal performance of your THINKCAR Thinkdiag Mini, follow these maintenance guidelines:

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Software Updates: Regularly check for and install software updates via the THINKDIAG app to ensure compatibility with new vehicle models and access to the latest features. Updates are typically free.
• Connection Care: Always plug and unplug the device carefully from the OBDII port to avoid damaging the connector pins.

Troubleshooting

If you encounter issues while using your Thinkdiag Mini, refer to the following common troubleshooting tips:

• Device Not Powering On: Ensure the Thinkdiag Mini is securely plugged into the vehicle's OBDII port. Check the vehicle's ignition status; some vehicles require the ignition to be on for the OBDII port to be active.
• Bluetooth Connection Issues:
  • Ensure Bluetooth is enabled on your smartphone.
  • Restart the THINKDIAG app.
  • Forget the device in your phone's Bluetooth settings and re-pair.
  • Ensure the Thinkdiag Mini is within Bluetooth range of your phone.
• No Communication with Vehicle:
  • Verify the device is correctly plugged into the OBDII port.
  • Confirm your vehicle is OBDII compliant (most vehicles from 1996 onwards in the US).
  • Check if the vehicle's ignition is on.
  • Ensure the correct vehicle software has been downloaded and selected in the app.
• Fault Code Persists After Clearing:

  If you clear a fault code without addressing the underlying issue, the code will reappear. The scanner clears the code from the vehicle's memory, but it cannot fix mechanical or electrical problems. It is crucial to repair the car first based on the diagnostic information, and then clear the fault code.

• App Freezing or Crashing:
  • Close and restart the app.
  • Ensure your smartphone's operating system is up to date.
  • Clear the app's cache (Android) or reinstall the app.
