Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner (if applicable), and a tire inflator.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Inflate Tires

Sub-steps:
1. If any tire pressure is below the recommended level (usually found on the driver's door jamb), inflate the tire(s) to the specified pressure using a tire inflator.
2. Recheck the pressure with the tire pressure gauge after inflating.
Tools Required: Tire inflator, tire pressure gauge.

3. Reset TPMS

Sub-steps:
1. After ensuring all tires are properly inflated, access the vehicle's settings through the infotainment system.
2. Navigate to the TPMS reset option in the menu.
3. Select the reset option and follow the prompts to complete the process.
Tools Required: None.

4. Replace TPMS Sensors (if necessary)

Sub-steps:
1. If the TPMS error codes indicate a faulty sensor, remove the tire from the wheel rim using a tire removal tool.
2. Replace the defective TPMS sensor with a new one, ensuring it is properly seated.
3. Reinstall the tire and balance it as necessary.
Tools Required: Tire removal tool, torque wrench (for reinstallation).
