Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, socket set, jack, jack stands, wrench.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle's battery to avoid any electrical issues.

2. Check Tire Pressure

Remove the valve cap from each tire.
Use a manual tire pressure gauge to measure the pressure.
Inflate or deflate the tires to the manufacturer-recommended pressure.

3. Inspect and Replace Tire Pressure Sensors

Tools Required: Torque wrench, replacement tire pressure sensors (if faulty).
Lift the vehicle using a jack and secure it with jack stands.
Remove the tire from the wheel using a socket set.
Detach the old tire pressure sensor from the valve stem and connect the new sensor.
Reattach the tire to the wheel, ensuring it is properly seated.
Torque the lug nuts to the manufacturer's specifications.

4. Reprogram the Tire Pressure Sensors

Reconnect the vehicle's battery.
Use the OBD-II scanner to reset the TPMS and reprogram the new sensors.
Follow the on-screen prompts to ensure proper pairing of sensors with the vehicle.

5. Test Drive and Calibration

Test drive the vehicle for at least 10 minutes to allow the system to calibrate.
Monitor the dashboard for any error messages regarding tire pressure.
