Solution

1. Preparation

Gather tools: OBD-II scanner, tire pressure gauge, TPMS reset tool, and jack.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Reset the TPMS

Locate the TPMS reset button (usually found under the steering column or in the glove box).
With the ignition turned to the "On" position (but the engine not running), press and hold the TPMS reset button until the TPMS light blinks three times.
Release the button and start the engine. The light should turn off after a few minutes if the system resets successfully.

3. Replace TPMS Sensors (if needed)

Remove Tire:
- Loosen the lug nuts using a socket set and remove the wheel.
Remove TPMS Sensor:
- Deflate the tire, then unmount it using a tire machine if necessary.
- Remove the valve nut and carefully take out the TPMS sensor from the tire.
Install New Sensor:
- Insert the new TPMS sensor into the valve stem and secure it with the valve nut.
Reinstall Tire:
- Remount the tire on the wheel and inflate to the correct pressure.
- Reattach the wheel to the vehicle and torque the lug nuts to the manufacturer's specified values (typically around 80-100 ft-lbs).
