Diagnostic Steps

1
Check tire pressure using a reliable tire pressure gauge.
2
Inspect all tires for visible damage, such as cuts, punctures, or sidewall bulges.
3
Verify if the tires are cold (check pressure before driving or at least three hours after driving).
4

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and tire repair kit (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve cap from the tire you are checking.
2. Press the tire pressure gauge onto the valve stem to get a reading.
3. Compare the reading to the recommended tire pressure (usually found on a sticker inside the driver's door).
4. If the pressure is low, use an air compressor to inflate the tire to the recommended PSI.
5. Recheck the pressure after inflating to ensure it is correct.
6. Replace the valve cap securely.

3. Inspect for Damage

Sub-steps:
1. Visually inspect each tire for signs of damage or foreign objects.
2. If you find a puncture, use a tire repair kit to seal it or consider replacing the tire if damage is severe.
3. Check the valve stems for any cracks or leaks and replace if necessary.

4. Reset Tire Pressure Monitoring System (TPMS)

Sub-steps:
1. After correcting tire pressure, navigate to the settings on the Tesla touchscreen.
2. Select 'Service' and then 'Tire Pressure' to reset the TPMS.
3. Ensure that the warning light has turned off after resetting.
