For persistent issues, try these advanced steps: Test with a different laptop to rule out PC-specific software conflicts or hardware issues. Temporarily disable antivirus software or firewalls. Check Windows Device Manager for any conflicting devices or COM port assignments. Use a voltmeter to verify power and ground at the vehicle's diagnostic port pins. Consider performing a clean uninstall and reinstall of Cummins Insite and all associated drivers.
