Tools Required: None specifically, but a soft cloth for cleaning may be helpful.
Ensure the vehicle is parked safely and powered down.

Open each door and locate the door switch (usually located in the door frame).

Manually press the switch to ensure it is functioning correctly.

3. Reset the Vehicle

With the vehicle in park, press and hold both scroll wheels on the steering wheel until the screen turns off and the Tesla logo appears.
Wait for the system to reboot, approximately 30 seconds.

4. Test Each Door

Open and close each door, ensuring the door latch engages properly.
Monitor the interior lights to see if they respond accordingly.
If the lights remain on after closing, proceed to check for sensor malfunctions.

5. Check Settings

Access the car settings through the touchscreen.
Navigate to the "Lighting" or "Interior" settings.
Ensure that the interior light delay is set to the desired time and that no override settings are activated.
