Solution

1. Preparation

Gather necessary tools: OBD-II scanner, tire pressure gauge, socket set, and a multimeter.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery before working on electrical systems for safety.

2. Check and Adjust Tire Pressures

Using a tire pressure gauge, check the pressure of all four tires.
Inflate or deflate tires to match the recommended pressure found on the driver’s side door jamb label.
After adjustments, drive the vehicle for a short distance to see if the TPMS light resets.

3. Replace TPMS Sensors (if necessary)

If sensors are found to be faulty:
1. Remove the wheel from the vehicle using a socket set.
2. Deflate the tire and remove it from the rim using a tire bead breaker.
3. Unscrew the old TPMS sensor from the valve stem and replace it with a new sensor.
4. Reinstall the tire onto the rim and inflate to the correct pressure.
5. Reinstall the wheel back onto the vehicle and torque the lug nuts to the manufacturer’s specifications.

4. Reprogram TPMS Sensors

If new sensors were installed, use an OBD-II scanner or TPMS tool to reprogram the sensors according to the vehicle’s manual.
Follow the specific programming instructions for the sensor to ensure proper communication with the vehicle's ECU.
