• Changing tire pressure monitoring sensors.
• Adding factory towbar wiring modules.

Common pitfalls & troubleshooting

• Interface driver mismatches causing connection failures — reinstall drivers and confirm OS compatibility.
• Antivirus/OS security blocking communications — add exceptions or use a clean diagnostic PC image.
