Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, jack, jack stands, and tire repair kit.
Ensure the vehicle is on a level surface and safely parked, with the engine off.

2. Check and Adjust Tire Pressure

Use the tire pressure gauge to measure the pressure in each tire, including the spare.
Inflate or deflate tires as necessary to match the manufacturer's recommended pressure (usually found on a sticker inside the driver's door).
Recheck all tire pressures after adjustment.

3. Inspect Tires for Damage

Visually inspect each tire for cuts, punctures, or bulges.
If any damage is found, repair or replace the affected tire as necessary.

4. Reset the TPMS

After ensuring proper tire pressure, use the OBD-II scanner to reset the TPMS if the warning light remains illuminated.
Follow the scanner's prompts to clear any TPMS-related error codes.

5. Test Drive

Take the vehicle for a short test drive to ensure the tire pressure warning light turns off.
Monitor the performance of the vehicle during the drive for any handling issues.
