Diagnostic Steps

1
Check all tire pressures with a reliable tire pressure gauge.
2
Verify that the tire pressures match the recommended specifications found on the driver’s side door jamb.
3
Inspect each tire for visible damage, punctures, or leaks.
4

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner (if needed).
Ensure the vehicle is parked on a level surface and the ignition is in the "OFF" position.

2. Inflate Tires

Locate the recommended tire pressure on the driver’s side door jamb.
If any tire is below the recommended pressure, use an air compressor to inflate to the specified PSI.
Recheck each tire's pressure after inflation.

3. Reset TPMS

Turn the ignition to the "ON" position without starting the engine.
Locate the TPMS reset button under the steering column or in the glove compartment (consult the owner’s manual if necessary).
Press and hold the TPMS reset button until the tire pressure light blinks three times, then release it.
Start the engine and wait for about 20 minutes for the system to recalibrate.

4. Verify Reset

Check if the tire pressure light remains off after the reset procedure.
If the light is still on, use the OBD-II scanner to clear any stored TPMS error codes.
