Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.
Tools Required: OBD-II scanner, tire pressure gauge, jack and jack stands, tire iron.

2. Check and Adjust Tire Pressures

Remove the valve caps from each tire.
Use a tire pressure gauge to check the pressure of all four tires, including the spare tire if applicable.
Inflate or deflate each tire to the recommended pressure found on the driver’s side door jamb.
Reinstall the valve caps securely.

3. Inspect and Replace TPMS Sensors (if necessary)

If any TPMS sensors are damaged or malfunctioning, remove the tire from the wheel using a tire iron and jack.
Detach the TPMS sensor from the valve stem.
- Tools Required: Tire machine or manual tools for tire removal (may require professional assistance).
Install the new TPMS sensor onto the valve stem.
Reinstall the tire onto the wheel and balance it if necessary.

4. Reset the TPMS

Turn the ignition to the "ON" position without starting the engine.
Locate the TPMS reset button (usually under the steering column or in the glove compartment).
Press and hold the reset button until the TPMS light blinks three times, then release it.
Start the engine and let it run for a few minutes to allow the system to recalibrate.
