Solution

1. Preparation

Gather necessary tools: tire pressure gauge, diagnostic scanner, and possibly a tire inflator.
Ensure the vehicle is parked on a level surface and the tires are cold (not driven recently).

2. Check and Adjust Tire Pressure

Sub-steps:
- Use the tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate the tires to match the recommended pressure found on the driver’s door jamb sticker.
Tools Required: Tire pressure gauge, air compressor or tire inflator.

3. Inspect Tires

Sub-steps:
- Examine each tire for visible damage, such as cuts or punctures.
- Look for signs of uneven wear that may indicate alignment issues.
Tools Required: None specifically, but a flashlight may help with inspection.

4. Reset TPMS

Sub-steps:
- Access the vehicle's settings via the touchscreen.
- Navigate to the service menu, select the TPMS reset option, and follow prompts to reset.
Tools Required: Tesla touchscreen interface.

5. Replace TPMS Sensors (if necessary)

Sub-steps:
- If diagnostic codes indicate sensor failure, remove the tire from the rim.
- Replace the faulty TPMS sensor with a new one, ensuring it is compatible with the Model 3 Highland.
- Reinstall the tire and ensure proper sealing.
Tools Required: Tire iron, tire levers, torque wrench, and possibly a TPMS activation tool.
