Solution

1. Preparation

Gather necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: OBD-II scanner, TPMS tool, tire pressure gauge, jack and jack stands.

2. Check and Adjust Tire Pressure

Remove the valve caps from each tire.
Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate the tires to match the manufacturer’s recommended specifications found on the driver’s side door jamb.
Reinstall the valve caps securely after adjustments.

3. Inspect TPMS Sensors

Safely lift the vehicle using a jack and secure it with jack stands.
Remove each tire (if necessary) to access the TPMS sensors mounted on the inner side of the tire.
Visually inspect the sensors for damage, dirt, or corrosion.
If any sensors are damaged, proceed to replace them with new sensors.

4. Reset the TPMS

After ensuring all tires are at the correct pressure and sensors are functioning, reset the TPMS system.
Turn the ignition to the "On" position without starting the engine.
Press the TPMS reset button, usually located under the steering column or in the glove box, until the TPMS light blinks three times.
Start the engine and allow the vehicle to run for a few minutes to complete the reset process.

5. Final Check

Lower the vehicle if it was raised.
Drive the vehicle for a short distance to allow the system to recalibrate.
Monitor the dashboard for any warning lights or error messages.
