Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, TPMS reset tool (if necessary)
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressures

Sub-steps:
1. Use the tire pressure gauge to measure the pressure of each tire.
2. Compare the readings with the recommended pressure found on the driver’s side door jamb.
3. Inflate or deflate tires to match the recommended pressure.

3. Inspect TPMS Sensors

Sub-steps:
1. Remove the tires if necessary to access the TPMS sensors.
2. Visually inspect each sensor for damage, ensuring they are properly seated and functional.
3. Replace any damaged sensors with new TPMS sensors compatible with the vehicle.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Locate the TPMS reset button (if equipped) usually found beneath the steering wheel or in the glove compartment.
3. Press and hold the button until the TPMS light blinks three times, then release it.
4. Start the vehicle and allow a few minutes for the system to recalibrate.
