If you encounter issues with your FOXWELL diagnostic tool, refer to the following common problems and solutions.

• Device Not Powering On:
  • Ensure the OBD-II cable is securely connected to both the vehicle's port and the tool.
  • Verify the vehicle's ignition is in the 'ON' position (engine off or running).
  • Check the vehicle's fuse for the OBD-II port.
• Communication Error:
  • Confirm the vehicle supports the OBD-II protocol (most vehicles after 1996 do).
  • Try connecting to a different vehicle to rule out a vehicle-specific issue.
  • Ensure the software is up to date.
• Codes Not Clearing:
  • Diagnostic Trouble Codes (DTCs) will not clear if the underlying fault is still present. Address the issue first.
  • Ensure the ignition is on and the engine is off when attempting to clear codes.
• Inaccurate Battery Test Results:
  • Ensure battery terminals are clean and connections are secure.
  • Verify the battery type and CCA rating entered into the tool (if applicable) match the battery being tested.
