Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and is in "Park."
Gather necessary tools: Tesla diagnostic tool, tire pressure gauge, and a flashlight for inspections.

2. Update Software

Connect the vehicle to Wi-Fi.
Navigate to "Software" on the touchscreen and check for updates.
If an update is available, follow on-screen prompts to install the update.

3. Tire Inspection and Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to match the recommended PSI listed in the owner's manual or driver’s door jamb.
Inspect tires for uneven wear or damage; replace if necessary.

4. Inspect ABS Sensors

Locate the ABS sensors at each wheel hub.
Visually inspect sensors for dirt, debris, or damage.
Clean the sensors with a soft cloth if dirty, and ensure connectors are secure.

5. Brake System Check

Check brake fluid level in the reservoir; top off with the manufacturer's recommended brake fluid if low.
Inspect brake pads for wear and replace if they are below the minimum thickness.
