Solution

1. Preparation

Gather necessary tools: Tesla mobile app, OBD-II scanner (if applicable).
Ensure the vehicle is parked in a safe location with sufficient charge to complete the diagnostics.

2. Access Battery Information

Open the Tesla app or vehicle touchscreen.
Navigate to 'Charging' and then 'Battery' settings.
Record the current battery capacity and compare it to the original specifications provided by Tesla.

3. Conduct a Range Test

Fully charge the vehicle to 100% using a home charger or Supercharger.
Reset the trip meter or note the current odometer reading.
Drive normally until the battery reaches a low state of charge (e.g., 10%).
Record the distance traveled during this test.

4. Analyze Results

Compare the distance traveled to the EPA-rated range for your model.
If the distance is significantly lower than expected, consider contacting Tesla service for further evaluation.
