Solution

1. Preparation

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

2. Check Tire Pressure

Sub-step 1: Remove valve caps from all tires.
Sub-step 2: Use the tire pressure gauge to check the pressure in each tire.
Sub-step 3: Inflate tires to the manufacturer's recommended pressure as stated in the owner's manual or on the driver’s door jamb.
Sub-step 4: Replace valve caps securely.

3. Inspect Tires

Sub-step 1: Visually inspect each tire for signs of damage or uneven wear.
Sub-step 2: If any damage is found, consider replacing the tire or having it repaired by a professional.
Sub-step 3: Check the tread depth; replace tires if tread is below the legal limit.

4. Check TPMS Sensors

Sub-step 1: Locate the TPMS sensors (usually mounted on the valve stems).
Sub-step 2: Inspect each sensor for signs of corrosion or damage.
Sub-step 3: If damaged, replace the TPMS sensor and ensure it is properly calibrated.

5. Reset TPMS

Sub-step 1: Follow the vehicle’s manual to reset the TPMS. This often involves turning the ignition on and holding the TPMS reset button until the light blinks.
Sub-step 2: Drive the vehicle for a short distance to allow the system to recalibrate.
