How to Reset Your Chevy Tire Pressure Lights

Every new car has a tire-pressure monitoring system (TPMS) that checks tire pressure.

It warns you if a tire is flat or not inflated enough with a light or message on the dashboard.

Your tires might lose air for different reasons like damage to the wheel, a hole, or a temperature change.

Once you find and fix the problem, like adding air or changing the tire, the TPMS light might go off by itself soon.

But if it doesn’t and you’re sure you fixed the problem, you’ll need to reset the TPMS manually.

For Chevy cars like the 2022 Chevrolet Trailblazer, you’ll need a special tool from General Motors to do this. You can buy it online or from a Chevy service shop near you.

Why is My TPMS Light On?

If you notice your TPMS light staying on after inflating your tires at a gas station, it could mean the system needs resetting.

There are several methods to reset it, including driving at 50 mph or above for 10 minutes, using the TPMS reset button, or inflating and deflating the tires.

However, if the light flashes, it might indicate a battery issue or a faulty sensor.

In either case, scheduling service is essential.

How Do You Reset Your Tire Pressure Lights?

1. Place the vehicle in service mode by holding the start/stop button for five seconds without pressing the brake pedal. On vehicles without a push-button ignition, turn the key to the “on” position without starting the engine.

2. Access the Tire Pressure page in the driver information center (i.e., the screen located in the gauge cluster) by tapping through the various menu pages with the steering-wheel arrow controls. (If you can’t find the Tire Pressure page, you may need to enable it via the Options menu.) If your vehicle doesn’t have these steering-wheel buttons, repeatedly press the trip-odometer-reset stalk until the gauge screen reads “relearn tire positions.”

3. Once there, press and hold the trip-reset stalk or the steering-wheel thumbwheel or checkmark. You should hear the horn chirp twice and see a “tire learning active” message in the information center.

4. Exit the vehicle and grab your TPMS relearn tool. Starting with the front driver’s tire, place the tip of the TPMS relearn tool against the tire sidewall near the wheel’s valve stem. Then Press the button on the tool to activate the sensor. You should also hear the horn sound, indicating that the system has identified and matched this sensor with this tire and wheel position.

5. Repeat this process for the remaining tires in this order: front passenger’s side, rear passenger’s side, and rear driver’s side.

6. Upon finishing the process with the rear driver’s tire, the horn will chirp twice, indicating that the TPMS sensor-matching process is complete. The “tire learning active” message should disappear.

7. Turn off the vehicle.

8. If the tire pressure is still low, fill the tires to the recommended pressures listed on the driver’s door jamb and start the car. That TPMS light or message should be gone.
