Test the outlet or charging station by plugging in another device to ensure it is functioning.
If using a home charging station, check the circuit breaker for any tripped switches.

5. Software Update and Reset

Connect to Wi-Fi and check for any available software updates via the vehicle’s screen.
If updates are available, follow the prompts to install.
After updates, perform a soft reset as described in the diagnostic steps.
