Solution

1. Preparation

Gather necessary tools: OBD-II scanner (optional), tire pressure gauge, and vehicle owner's manual.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Inflate Tires

Use a tire pressure gauge to measure the pressure in each tire.
Inflate tires to the recommended PSI as specified in the vehicle’s owner manual or on the tire placard.

3. Reset the TPMS

Turn the ignition to the "ON" position without starting the engine.
Press the accelerator pedal three times, then turn the ignition to "OFF".
Wait for a few seconds, then turn the ignition back to "ON".
The TPMS light should blink and then turn off, indicating the reset is successful.

4. Drive the Vehicle

Drive the vehicle for about 10 minutes at speeds of over 20 mph to allow the TPMS to recalibrate.
