Solution

1. Preparation

Gather tools: Tire pressure gauge, TPMS reset tool (if necessary), and an OBD-II scanner (if needed).
Ensure vehicle is parked on a level surface and turned off before starting.

2. Check and Adjust Tire Pressure

Remove the valve caps from all tires.
Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to match the recommended pressure listed on the driver's door jamb sticker.
Replace the valve caps securely after adjustments.

3. Inspect TPMS Sensors

If the problem persists, remove the tires if necessary to access TPMS sensors.
Inspect each TPMS sensor for damage or misalignment.
Replace any damaged sensors with new ones as needed.

4. Reset TPMS

Turn on the Tesla Model 3 and access the settings menu.
Navigate to the 'Service' section and select 'TPMS Reset' or 'Monitor Tire Pressure'.
Follow the prompts to complete the reset process.

5. Test Drive

Drive the vehicle for at least 10-15 minutes at varying speeds to allow the TPMS to recalibrate.
Monitor the dashboard for any warning lights or alerts.
