Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, jack and jack stands, tire iron, and a torque wrench.
Ensure vehicle is parked on a level surface and the ignition is off.

2. Check and Adjust Tire Pressure

Sub-step 1: Remove valve caps from each tire.
Sub-step 2: Use the tire pressure gauge to check the pressure against manufacturer specifications (found on the driver’s side door jamb).
Sub-step 3: Inflate or deflate tires as necessary to reach the recommended pressure.
Sub-step 4: Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-step 1: Lift the vehicle using a jack and secure it with jack stands.
Sub-step 2: Remove the wheel from the affected tire using a tire iron.
Sub-step 3: Locate the TPMS sensor mounted on the rim inside the tire.
Sub-step 4: If sensor is damaged, remove it by unscrewing the retaining nut and disconnecting the wiring.
Sub-step 5: Install the new TPMS sensor, ensuring it is securely fastened and connected.

4. Reset the TPMS

Sub-step 1: Turn the ignition key to the "ON" position without starting the engine.
Sub-step 2: Locate the TPMS reset button (usually near the steering column).
Sub-step 3: Press and hold the reset button until the TPMS light blinks three times, then release it.
Sub-step 4: Start the engine and allow the vehicle to run for 20 minutes to complete the reset.
