Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Tools Required: Tire pressure gauge, OBD-II scanner, TPMS reset tool (if needed).
Safety Warnings: Ensure the vehicle is in park and the engine is off before working on tires.

2. Check and Adjust Tire Pressures

Remove valve stem caps from each tire.
Use the tire pressure gauge to measure the pressure of each tire.
Inflate or deflate each tire to the manufacturer's recommended pressure, which can typically be found on a sticker inside the driver’s door jamb.
Reinstall valve stem caps securely.

3. Inspect and Replace TPMS Sensors (if necessary)

Remove the wheel from the vehicle using a socket set.
Detach the tire from the wheel rim using a tire machine or manual tire tools.
Locate the TPMS sensor mounted inside the tire.
If the sensor is damaged or the battery is dead, replace it with a new TPMS sensor.
Reinstall the tire to the rim and mount the wheel back onto the vehicle.

4. Reset the TPMS

Turn on the ignition without starting the engine.
Navigate to the settings on the vehicle's infotainment system.
Select the option for resetting the TPMS and follow the prompts.
Alternatively, use the TPMS reset button (if equipped) according to the owner's manual.

5. Final Check

Re-scan the vehicle's OBD-II system to ensure no TPMS-related error codes are present.
Drive the vehicle for a short distance to allow the TPMS to recalibrate and monitor the light status.
