How to Enable Service Mode with X431

Scanner Settings: Set the X431 scanner to Bluetooth communication mode. To access the hidden menu for this, click VCI in the “Personal Center” more than 8 times.
Software Selection: In the Tesla software on your device, choose Manual Selection, pick your model, and select the LAN function.
Activation: Follow the on-screen prompts to “Enter Service Mode.” Once successful, a red “Service Mode” notification will appear on the Tesla’s center touchscreen.
