Solution

1. Preparation

Gather tools: OBD-II scanner, TPMS tool, tire pressure gauge.
Ensure the vehicle is on a flat surface and the tires are cool.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate the tires to the manufacturer-recommended pressures (found on the driver’s door jamb).

3. Inspect TPMS Sensors

Remove the wheel if necessary: Use a jack to lift the vehicle, and secure it with jack stands.
Inspect each sensor: Carefully remove the valve stem cap and check for any visible damage or corrosion.
Replace batteries if needed: If using a TPMS tool indicates low battery, replace the sensor battery according to the manufacturer’s instructions.

4. Reset the TPMS

Turn the ignition to the “ON” position without starting the engine.
Locate the TPMS reset button (often found beneath the steering wheel).
Press and hold the reset button until the TPMS light blinks three times, then release it.
Start the engine and allow it to run for a few minutes to ensure the system resets.

5. Recheck System Functionality

After resetting, drive the vehicle for about 10-15 minutes to allow the TPMS to recalibrate.
Verify that the TPMS warning light has turned off and that tire pressures are reading correctly.
