How to reset tire pressure light: 6 must know steps to ensure safety

Tire pressure should be maintained for safe and optimal car performance that will lead to the life span of your car tires. If the tires of your car are inflated or not in proper use, then you may reset it. If you don’t know how to reset tire pressure light then read ahead; 

For this, modern vehicles come up with a cutting-edge Tire pressure monitoring system (TPMS) that alarm you automatically when the tire pressure starts getting lower than the recommended pressure.

This Tire Pressure Monitoring System should be activated for safety even when you inflated your car tires in a correct pressure. So whenever you have some upcoming danger, the TPMS light will automatically turns on and alarm you about the danger.

In this detail, we will tell you all about the tyre pressure lights along the ways to reset them. So, if you found it beneficial, then go ahead and read this article till the end.

Let’s get start to discuss;

Understanding the Tire Pressure Monitoring System (TPMS)

A Tire Pressure Monitoring System (TPMS) is a safety feature now available in most cars to ensure safety. This safety feature monitors the tyre air pressure and alerts the driver to fix it when the pressure is too low.

 Majorly there are two types of Tire Pressure Monitoring Systems (TPMS) that are;

• Direct Tire Pressure Monitoring System (TPMS): This tyre of TPMS comes with a sensor inside every tire and measure the pressure directly. When the tire pressure getting below the recommended line then system will automatically sends signal to car computer that a driver can see on the dashboard in the form of tire pressure light.

• Indirect Tire Pressure Monitoring System (TPMS): These types of TPMS have Anti-Lock Braking System (ABS) that monitors the rotational speed of the tires. As the tire with low pressure have small diameter and rotates at fast rate. That is how the system detects the pressure level of tire and triggers the tire pressure light.

Why Does the Tyre Pressure Light Stay On?

Tire Pressure Light is normally turns on when it indicates that the battery needs to be replaced. It also means that the battery you already have is suffering from some sort of errors or the sensor is damaged that should be changed.

After solving all these issues and inflating your tires in the correct position, you may expect that the tire pressure light should turn off automatically. There are many reasons that the light stays on, which are discussed here;  

• Incorrect Tire Pressure: Double check is an important thing. Sometimes you do everything by yourself and fill the tyres accurately, but still, the tyre pressure is not within the recommended pressure range. So, you should cross-check with any professional.

• Tire Pressure Monitoring System (TPMS) Sensor Issue: The light sensor of the tire pressure Monitoring System (TPMS) can be damaged, which may cause the full-time light even after having a desired tire pressure.

• Temperature Fluctuation: Tire Pressure can be change with the variation of temperature variation. This will also affect the light sensor and make it on. For example, if the weather is colder than the previous tire pressure check and now drop slightly, it will also trigger the light.

• System Reset Required: If everything is still perfect, then it only demands a manual reset. Normally, some TPMS require a manual reset after inflating the tyres.

Steps to Reset the Tire Pressure Light

If the light is still on after inflation and balancing the tire pressure then you only need to do a tire pressure light reset. There are various different ways of resetting that will depend on different model and vehicle type.

Here, we are going to tell you about some general steps that will work with most vehicles, and you can easily go ahead with these;

• Check Tire Pressure;

Before going ahead with any other step, make sure that all your tyres have the desired temperature range. If you don’t know about the recommended pressure for your car tyres, then you may check the notes or call the manufacturer.

It can also be found on the driver’s side door jamb. Furthermore, there are some digital tyre pressure gauge tools that can help you in this regard.

• Drive at a Steady Speed

When you drive the car at a steady speed for about 20 to 30 minutes, the TPMS light can mostly reset automatically during or after the drive. This will allow the system to find and know the correct tyre pressure.

So, drive at 50 mph while maintaining a steady pace for 20 to 30 minutes and then see the results.

• Use the Reset Button

Many vehicles have a TPMS reset button that is usually located under the steering wheel or around the dashboard. If you don’t find the button then contact with the manufacturer for exact location.

After that press and hold the button until the light blinks three times and then release. Turn on your vehicle car and let it run for about 15 minutes so that the system will reset the light itself. That is how to reset tire pressure light. 

• Disconnect and Reconnect the Battery

If the reset button not work the open the hood after turning off the vehicle. Then use a wrench and disconnect the negative cable battery. Let it rest for about 15 minutes and reconnect it. Turn the vehicle on and check if the light turns off or not.  

• Check the spare tyre.

Some vehicles come up with an extra tyre that is included in TPMS. So make sure that the spare tyre is properly inflated; otherwise, the light can still turn on.

• Professional Assistance

If you have tried all the methods and nothing worked then it is the time to check it by professional. The professional have knowledge about some special tools and have some tricks that we don’t know.

The Bottom Line

Knowing how to reset the TPMS light is good, but it is also good for preventing the light from coming to its first place again. In this regard, we suggest you check the tyre pressure and rotate the tyres timely with seasonal adjustments.

By following these steps and above-described detail, you will not only learn how to reset tire pressure light but also get a safe drive with optimal performance but also increase the life span of the tires.
