⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety glasses when working with tires and compressors.
•Ensure the vehicle is securely parked and turned off before beginning any inspection or repair work.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Inaccurate tire pressure readings displayed on the touchscreen
•Fluctuating tire pressure readings
•Handling issues, such as pulling to one side or unstable ride
•Vehicle alerts indicating low tire pressure

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect each tire visually for any signs of damage, such as punctures or sidewall bulges.
3
Verify if the TPMS is functioning by cycling through the vehicle settings to check for error messages.
4
Use an OBD-II scanner to check for any error codes related to the TPMS system.
5
Confirm the tire pressures against the manufacturer's specifications, typically found on the driver’s door jamb.

Solution

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, OBD-II scanner.
Ensure the vehicle is parked on a level surface and is turned off before starting any work.

2. Inflate Tires

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Using the tire pressure gauge, measure the tire pressure.
3. If any tire is below the recommended pressure (specified on the door jamb), use an air compressor to inflate it to the correct PSI.
4. Replace the valve stem caps after inflating each tire.

3. Reset TPMS

Sub-steps:
1. Access the vehicle’s settings on the touchscreen.
2. Navigate to “Service” and then select "Reset Tire Pressure Monitoring System."
3. Follow the prompts to confirm the reset.
4. Allow the vehicle to recalibrate the TPMS system, which may take a short drive.

4. Inspect and Replace Faulty Components (if necessary)

Sub-steps:
1. If the warning persists, check the TPMS sensors on each wheel for proper operation.
2. If a sensor is found to be malfunctioning, remove the tire from the wheel.
3. Replace the TPMS sensor with a new one, ensuring it is compatible with the Model S Plaid.
4. Reinstall the tire and balance it as necessary.

5. Final Checks

Sub-steps:
1. Re-check tire pressures after repairs and adjustments.
2. Go for a short test drive to ensure the warning light remains off and the TPMS is functioning correctly.
