You'll also need to provide vehicle registration and proof of ownership, and the vehicle must be present at the dealership.

⚠️ Common Issues and Troubleshooting

Issue: "PIN Not Accepted in DTS Monaco"

Possible Causes:

• Incorrect serial number entered during PIN retrieval
• NTG4 unit was replaced (original PIN won't work with new unit)
• DTS Monaco software version incompatibility
• Communication error between diagnostic equipment and NTG4 unit

Solution: Verify serial number, ensure correct DTS software version, check diagnostic connection, and contact our support if issues persist.

Issue: "DTS Monaco Cannot Connect to NTG4"

This usually indicates a connection problem. Check diagnostic interface connection, OBD port connection, vehicle ignition status, and DTS Monaco software configuration. Ensure you're using a compatible diagnostic interface.

Issue: "System Still Locked After PIN Entry"

If the system remains locked after entering the PIN via DTS Monaco, verify that the PIN was entered correctly, check for any error messages in DTS, and ensure the NTG4 unit is the original unit (not replaced). If the unit was replaced, you'll need the serial number of the new unit.
