Tip: Please read through all content below before proceeding. In an effort to reduce the complexity of the remote coding session, all points below should be strictly adhered to. Lack of preparation will result in delays and possibly re-scheduling of appointment. 

Pre-requisites: 

• MY 24 vehicle model and control module matches table above.
• Unrestricted internet access to ODIS tester.
• ODIS tester MUST  be at the latest software level to support the remote coding session.
• Microsoft Teams installed on scan tool (Teams icon on desktop).
• Install Vector Remote Access Point onto scan tool.
• Technician can login to email on scan tool.
• Technician has a headset with microphone connected to scan tool.
• Technician availability of approximately 2 hours.
