How To Reprogram Your Tire Sensors?

In car driving, abnormal tire pressure, abnormal temperature, and inconsistent wear of the four wheels may cause tire blowout and wheel slippage during the driving process of the car, which will affect the safety of the driver.

When we found abnormalities in car tires, our first reaction was to replace our tires.

Why change tires?

Getting new tires, or tire rotations, is one of the easiest ways to keep your car, truck or SUV in top running condition.

Regular replacement of tires can enhance the performance of the car, reduce the wear of the car tires, balance the wear of the car tires, and prolong the service life of the tires.

Why does the ECU fault light come on after changing the tires?

Modern cars typically employ a direct tire pressure monitoring system (TPMS), which includes sensors mounted on each tire. These sensors monitor the air pressure and temperature of the tires and transmit the information to the vehicle's electronic control unit (ECU).

When tires are changed, if the tire sensors are not reprogrammed or calibrated, the vehicle's TPMS system may not properly recognize the newly installed tires and sensors. Because each sensor has a unique identification number (ID), the ECU needs to know the location and ID of each sensor in order to accurately read and process the data from the tire sensors.

A Step-by-Step Guide to Resetting the Tire Pressure Light

When the TPMS scanner has reprogrammed the tire sensors, the tire pressure light will go off automatically. If not, here are a few different things you can try:

• Drive at 50 mph or more for 10 minutes to reset the sensor. This will cause your sensors to reset the next time you start your car.
• With the vehicle off, turn the key to the "On" position, but do not start the car. Press and hold the TPMS reset button until the tire pressure light flashes 3 times, then release. Start the car and wait about 20 minutes for the sensors to refresh. You'll find a tire pressure monitor reset button under the steering wheel. If you can't find it, refer to your vehicle's owner's manual.
• Inflate all tires (including the spare) to 3 PSI over the recommended value, then deflate completely. After all the air has been deflated, re-inflate to the recommended tire pressure.
• With the vehicle off, use a wrench to disconnect the positive battery cable. Start the car and honk the horn for about three seconds. This will release any charge still stored in the vehicle. Then reconnect the battery.
