Solution

1. Preparation

Gather all necessary tools including a tire pressure gauge, OBD-II scanner, and possibly a jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Remove the valve caps from all tires.
2. Use the tire pressure gauge to check each tire's pressure.
3. Inflate or deflate each tire as necessary to match the recommended pressure (typically found on the driver's side door jamb).
4. Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. Remove the tire from the wheel using a jack and jack stands.
2. Dismount the tire from the wheel using a tire machine.
3. Inspect the TPMS sensor for damage or corrosion.
4. If faulty, replace the TPMS sensor with a new one compatible with Tesla Model Y.
5. Remount the tire and balance the wheel before reinstallation.

4. Reset TPMS

Sub-steps:
1. Turn on the vehicle and access the TPMS reset function from the touchscreen.
2. Follow the prompts to reset the TPMS system.
3. Confirm that the TPMS warning light has turned off.
