Solution

1. Preparation

Ensure all tools and equipment are gathered.
Park the vehicle on a level surface and turn off the engine.
Gather necessary tools: tire pressure gauge, OBD-II scanner, and possibly a TPMS reset tool.

2. Tire Pressure Check

Sub-step 1: Remove valve caps from each tire's valve stem.
Sub-step 2: Attach the tire pressure gauge firmly to the valve stem and take a reading.
Sub-step 3: Record the pressure and compare it to the recommended pressure.

3. Tire Inspection

Sub-step 1: Visually inspect each tire for signs of damage (cracks, bulges, punctures).
Sub-step 2: Check the tread depth to ensure adequate grip and safety.
Sub-step 3: Ensure the valve stems are not leaking by applying soapy water to the area and looking for bubbles.

4. TPMS Reset

Sub-step 1: If the tires are properly inflated, follow the manufacturer's instructions to reset the TPMS, which may involve turning the ignition to the "On" position without starting the engine.
Sub-step 2: Locate the TPMS reset button, often found under the steering wheel or in the glove box.
Sub-step 3: Press and hold the reset button until the TPMS light blinks three times and then release it.
