Troubleshooting

If you encounter issues with your NEXPEAK NX501 scanner, refer to the following common troubleshooting tips:

• No communication with vehicle: Verify that your vehicle is OBDII compliant (model year 1996 or newer for US vehicles). Check the vehicle's OBDII port for any damage or loose connections. Ensure the ignition is in the ON position (engine off or running, depending on the test).
• Software update issues: The UPLINK software is for Windows computers only. Ensure your operating system is supported (Windows XP-10). If issues persist, refer to the official website for updated drivers or contact NEXPEAK after-sale service.
• Incorrect readings or errors: Ensure the vehicle's battery voltage is stable (monitored by the scanner). If the issue persists, try clearing codes and re-running the diagnostic.

For any persistent issues, please refer to the comprehensive user manual included in the package or contact NEXPEAK customer support.
