Solution

1. Preparation

Gather Tools: Obtain an OBD-II scanner, tire pressure gauge, and a jack if tire removal is necessary.
Safety Precautions: Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Check and Adjust Tire Pressures

Sub-step 1: Remove valve caps from all tires.
Sub-step 2: Use the tire pressure gauge to measure the pressure in each tire.
Sub-step 3: Inflate or deflate tires to match the recommended PSI specified on the driver's door jamb sticker.
Sub-step 4: Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-step 1: If a sensor is faulty or damaged, raise the vehicle using a jack and remove the wheel.
Sub-step 2: Unscrew the sensor from the valve stem using a wrench.
Sub-step 3: Install the new TPMS sensor, ensuring it is tightened to the manufacturer's torque specifications (typically around 4-5 ft-lbs).
Sub-step 4: Reinstall the wheel and lower the vehicle.

4. Reset TPMS

Sub-step 1: Start the vehicle and ensure the TPMS light is on.
Sub-step 2: Locate the TPMS reset button (usually found beneath the steering wheel or in the glove compartment).
Sub-step 3: Press and hold the reset button until the TPMS light blinks three times, then release it.
Sub-step 4: Drive the vehicle for a short distance (usually around 10 minutes) to allow the system to recalibrate.
