Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, jack and jack stands, lug wrench, TPMS reset tool (if applicable).
Safety Warnings: Ensure the vehicle is on a flat surface and turned off before starting. Use jack stands for safety when lifting the vehicle.

2. Check and Adjust Tire Pressures

Sub-steps:
- Remove the valve caps from all tires.
- Use the tire pressure gauge to check the pressure in each tire.
- Inflate or deflate each tire to the recommended pressure specified in the owner’s manual (usually found on the driver’s door jamb).
- Replace the valve caps securely.

3. Reset the TPMS

Sub-steps:
- Turn the ignition key to the ON position without starting the engine.
- Locate the TPMS reset button (often found beneath the steering column or in the glove compartment).
- Press and hold the TPMS reset button until the indicator light blinks three times, then release it.
- Start the engine and drive the vehicle for a short distance (approximately 10-15 minutes) to allow the system to recalibrate.

4. Replace Faulty Sensors (if necessary)

Sub-steps:
- If the tire pressure sensors are found to be faulty, lift the vehicle using a jack and secure it with jack stands.
- Remove the wheel using a lug wrench.
- Detach the old tire pressure sensor from the wheel (this may require tire dismounting).
- Install the new sensor, ensuring it is properly seated.
- Reassemble the wheel and lower the vehicle.
