Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Wear safety glasses and gloves.

2. Tire Inspection

Remove the valve stem caps from each tire.
Use a tire pressure gauge to check the pressure of each tire.
Inspect tires visually for any signs of wear, damage, or embedded objects.
Inflate tires to the recommended PSI as per the label inside the driver's door.

3. Sensor Inspection

Jack up the vehicle and remove the tires one by one.
Locate the TPMS sensor inside the tire mounted on the rim.
Inspect the sensor for physical damage or corrosion.
Ensure that the sensor's battery is functional; consider replacing the sensor if it's damaged or if the battery is dead.

4. Receiver Module Check

Locate the TPMS receiver module (usually found near the spare tire or under the dashboard).
Inspect wiring for cuts, frays, or corrosion.
Clean any corrosion found on connectors with electrical contact cleaner.

5. Reset TPMS

Turn the ignition to the "ON" position without starting the engine.
Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
Start the vehicle and allow it to run for a few minutes to complete the reset process.
