Solution

1. Preparation

Ensure all tires are inflated to the correct pressure.
Gather necessary tools: OBD-II scanner (optional), tire pressure gauge.

2. Access the TPMS Reset Procedure

Start the vehicle and allow it to run for a few minutes to initialize the systems.
Locate the TPMS reset button, typically found under the dashboard on the driver's side or in the glove compartment.

3. Reset the TPMS

Press and hold the TPMS reset button until the tire pressure light blinks three times, then release the button.
Drive the vehicle at speeds above 30 mph for at least 10 minutes to allow the system to calibrate and reset.

4. Confirm Reset

After driving, check if the tire pressure light has turned off.
If the light remains on, repeat the reset process or use an OBD-II scanner to check for any remaining error codes.
