Solution

1. Preparation

Ensure all tires are inflated to the correct pressure (typically found on the driver’s side door jamb).
Have the vehicle parked on a level surface, and turn the ignition to the "ON" position without starting the engine.

2. Reset the TPMS

Locate the TPMS reset button, usually found beneath the steering column or in the glove compartment.
Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
Start the engine and let it run for a few minutes to allow the system to recalibrate.
Turn off the engine and then restart it to ensure the TPMS light remains off.

3. Check for Remaining Issues

If the TPMS light remains on after resetting, recheck tire pressures and inspect for any malfunctioning sensors or damaged tires.
If necessary, use a TPMS scanner to diagnose any fault codes related to the TPMS.
