Solution

1. Preparation

Ensure the vehicle is in a safe and static position.
Gather necessary tools: OBD-II scanner, microfiber cloth, and a soft-bristle brush for cleaning sensors.

2. Software Update

Connect the vehicle to Wi-Fi and check for available software updates through the touchscreen.
If an update is available, initiate the download and installation process, following on-screen prompts.

3. Clean Sensors and Cameras

Use a microfiber cloth to clean the front and rear cameras, as well as ultrasonic sensors.
For stubborn dirt, utilize a soft-bristle brush to gently remove debris without scratching the surface.

4. Battery Inspection

Access the battery management system via the touchscreen.
Check the state of charge and ensure that it is above the minimum threshold for Autopilot functionality.
If the battery is low, charge the vehicle to the appropriate level.

5. Environmental Adjustments

Test Autopilot in varied conditions, ensuring that road markings are clear and weather does not impair sensor performance.
If issues persist in specific conditions, note them for further evaluation by Tesla service.
