Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, jack, jack stands, lug wrench, and a TPMS reset tool if necessary.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the tire pressure gauge to measure the pressure of each tire.
3. Inflate or deflate the tires to match the recommended pressure (found on the driver’s door jamb sticker).
4. Reinstall the valve stem caps securely.

3. Inspect Tires

Sub-steps:
1. Visually inspect each tire for cuts, punctures, or bulges.
2. Check the tread depth using a tread depth gauge.
3. If any tire shows damage or excessive wear, replace it with a suitable tire.

4. Check TPMS Sensors

Sub-steps:
1. Remove the tires if needed to access the TPMS sensors.
2. Inspect each sensor for corrosion or physical damage.
3. Replace any damaged sensors with new ones.

5. Reset TPMS

Sub-steps:
1. Follow the vehicle manual to locate the TPMS reset button (usually found under the steering wheel).
2. With the ignition in the “ON” position (engine off), press and hold the TPMS reset button until the warning light blinks three times.
3. Drive the vehicle at speeds of 30-60 mph for about 10 minutes to allow the system to recalibrate.
