3.1 Scanner Not Powering On

• Problem: The red light on the OBD2 scanner does not illuminate when plugged into the vehicle.
• Solution:
  • Check the OBD Port Fuse: The most common reason for this issue is a blown fuse controlling the OBD port. The OBD port is often on the same circuit as the cigarette lighter or wipers.
  • Test in Another Vehicle: If the scanner does not power on in multiple vehicles, it may indicate a faulty unit. Contact us for warranty support.

3.2 Bluetooth Signal Not Found

• Problem: Your phone or tablet cannot locate the Bluetooth signal from the OBD2 scanner.
• Solution:
  • Ensure Scanner is Powered On: Verify that the red light on the scanner is illuminated, indicating it is powered on.
  • Unpair and Restart: Unpair all Bluetooth devices from your phone, restart the phone, and try again. This can resolve glitches or bugs that may be interfering with the connection.

3.3 Unable to Clear Check Engine Light

• Problem: You are using the OBD2 scanner to clear the check engine light, but the light remains on.
• Solution:
  • Clear with Engine Running: Try clearing the code with the vehicle fully running.
  • Clear in ACC Mode: If that fails, try clearing the code with the vehicle in ACC (Accessory) mode but not running.
  • Address Underlying Issue: Some codes are “instant,” meaning the light will reappear immediately if the underlying problem is not fixed. Ensure the issue causing the code is resolved.

3.4 Scanner Not Reading ABS, SRS, or Other Lights

• Problem: The OBD2 scanner is not reading ABS, SRS, VSC, Oil Change, or Maintenance lights.
• Solution:
  • OBD2 Limitations: Standard OBD2 scanners primarily read and clear check engine lights related to emissions. They cannot assist in reading or clearing lights related to other vehicle systems.
  • Use Specialized Tools: For these lights, you will need to use a different, more specialized tool or take the vehicle to a professional repair shop.

3.5 App Cannot Find Adapter or Connect to Vehicle

• Problem: The OBD2 app states it cannot find the adapter, cannot connect to the vehicle, or you are having Bluetooth connection problems.
• Solution:
