Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, TPMS tool, multimeter, jack and jack stands.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the negative battery terminal to avoid electrical issues.

2. Inflate Tires

Using an air compressor, inflate the tires to the recommended pressure specified on the driver's side door jamb.
After inflating, wait a few minutes before proceeding to the next step.

3. Reset TPMS

Reconnect the negative battery terminal.
Turn the ignition to the "On" position without starting the engine.
Follow the specific TPMS reset procedure outlined in the owner's manual, which may involve holding down a reset button or navigating through the vehicle settings.

4. Replace Faulty Sensors (if necessary)

Tools Required: Tire iron, TPMS tool, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel where the sensor has been diagnosed as faulty.
Use a tire iron to remove the tire from the rim, then access the TPMS sensor.
Replace the faulty sensor with a new one, ensuring it is correctly seated.
Reinstall the tire, tightening the lug nuts to the manufacturer's specified torque.

5. Verify Functionality

Lower the vehicle back to the ground.
Start the engine and check if the TPMS warning light is off.
Verify that all tire pressures are correctly displayed on the dashboard.
