Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, OBD-II scanner (if needed), and a jack with jack stands.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve cap from each tire.
2. Use the tire pressure gauge to measure the current pressure.
3. Refer to the manufacturer’s recommended tire pressure (found on the driver’s door jamb).
4. If pressure is low, use an air compressor to inflate the tire to the correct psi.
5. If over-inflated, release air until the correct pressure is achieved.
6. Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the TPMS sensor.
3. Check the sensor for physical damage or corrosion.
4. If damaged, replace the TPMS sensor with a compatible one.
5. Reinstall the wheel and lower the vehicle.

4. Reset TPMS

Sub-steps:
1. Turn on the vehicle and access the touchscreen.
2. Navigate to 'Service' > 'Tire Pressure Monitoring System.'
3. Follow the prompts to reset the TPMS settings.
4. Drive the vehicle for a short distance to ensure the system recalibrates.
