Keep VCI3 Connected to Update Important Status Information and Complete the Login

If you see this notice when you start a diagnosis (i.e., when VCI3 is about to communicate with the vehicle), make sure you are on a network (Wi-Fi, LTE, or 5G), log out of the diagnostic app, and then log back in while keeping VCI3 connected.

Why do I keep seeing this notice?

If you don’t re-login, the notice will reappear every time you try to enter features that require vehicle communication, including:

• Smart Diagnosis
• S/W Management
• ECU Upgrade
• Any other menu that initiates VCI3 ↔ vehicle communication

Recommended steps (in order)

1. Check your network — connect to a stable Wi-Fi, LTE, or 5G network.
2. Confirm VCI3 power/connection — keep Bluetooth or USB connected.
3. Log out of the diagnostic app (required) to refresh the session/token.
4. Fully close the diagnostic app and reopen it.
5. Log in again while keeping VCI3 connected to update important status information.
