Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, air compressor (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check Tire Pressure

Use the tire pressure gauge to measure the pressure of each tire.
Compare the readings to the recommended pressure values found in the owner's manual or on the driver's side door jamb.
If any tire is below the recommended pressure, inflate it using an air compressor.

3. Inspect Tires

Visually inspect each tire for damage, including punctures, cuts, or bulges.
If damage is found, consider replacing the affected tire or having it repaired by a professional.

4. Reset TPMS

Start the vehicle and allow it to run.
Access the TPMS reset option through the vehicle's infotainment system or dashboard menu.
Follow the prompts to reset the TPMS, which will recalibrate the system for the new tire pressures.

5. Final Checks

After resetting, monitor the tire pressure warning light for any re-illuminations.
Drive the vehicle for a short distance to ensure the TPMS updates.
