Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, TPMS tool, and a jack if tire removal is necessary.
Park the vehicle on a level surface and turn off the engine.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in all tires.
- Sub-steps:
  - Remove the valve cap from each tire.
  - Press the gauge onto the valve stem firmly until a reading is obtained.
  - Record the pressure readings.
Inflate or deflate tires to match the recommended pressure as indicated on the door jamb sticker.

3. Inspect Tires

Visually inspect each tire for damage.
- Sub-steps:
  - Look for cuts, bulges, or embedded objects (nails, glass).
  - Check tread depth using a tread depth gauge or penny test.
  - If any issues are found, consider replacing the tire or repairing it as necessary.

4. Reset TPMS

Access the TPMS reset option via the vehicle’s infotainment system or dashboard controls.
- Sub-steps:
  - Navigate to the settings menu, find the TPMS or Tire section.
  - Follow the prompts to reset the system.
  - Drive the vehicle for a few minutes to allow the system to recalibrate.

5. Inspect TPMS Sensors

If the warning persists, inspect the TPMS sensors.
- Sub-steps:
  - If the vehicle is equipped with direct TPMS, remove the tire to access the sensor.
  - Check for any visible damage or corrosion on the sensor.
  - Use a TPMS tool to check the sensor's battery status and functionality.
  - Replace any faulty sensors as needed.
