Diagnostic Steps

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and possibly a jack and jack stands.
Ensure the vehicle is parked on a level surface.

2. Check Tire Pressure

Remove the valve cap from each tire.
Use the tire pressure gauge to measure the pressure.
If the pressure is below the recommended level, proceed to inflate the tire.

3. Inflate Tires

Connect the air compressor to the valve stem.
Inflate the tire to the recommended pressure as indicated on the driver’s door jamb or in the owner’s manual.
Recheck the pressure with the gauge after inflating.
Replace the valve cap securely.

4. Inspect and Repair

If a tire is damaged (e.g., punctured), remove the tire using a jack and jack stands.
Inspect the inside of the tire and the rim for any signs of damage.
If repairable, use a tire plug kit or take the tire to a professional for patching.
If the tire is not repairable, replace it with a new tire.

5. Reset TPMS (if applicable)

After ensuring all tires are at the correct pressure, reset the TPMS light according to the vehicle's manual. This typically involves turning the ignition on without starting the engine and pressing the TPMS reset button.
