What Does Service Tire Monitor System Mean?

Have you ever been driving down the road and seen a warning light on your dashboard that says “Service Tire Monitor System”? It can be a bit confusing, especially if you’re not familiar with what it means or how to address it. In this article, we’ll delve into the details of the Service Tire Monitor System (STMS) and provide you with all the information you need to know.

What is the Service Tire Monitor System?

The Service Tire Monitor System is a feature in modern vehicles that helps drivers keep track of the air pressure in their tires. It uses sensors located on each tire to monitor the pressure and provides warnings if any tire is underinflated. The primary purpose of the STMS is to enhance safety by ensuring that your tires are properly inflated, reducing the risk of tire blowouts and other tire-related accidents.

How Does the Service Tire Monitor System Work?

To understand how the Service Tire Monitor System works, let’s break it down into three main components: the sensors, the control module, and the driver information system.


The sensors, typically located in the valve stem of each tire, measure the air pressure within the tire. These sensors constantly monitor the pressure and send the information to the control module.

Control Module:

The control module is the brain of the STMS. It receives the data from the sensors and compares the tire pressure readings to a predetermined safe range. If any tire falls outside of this range, the control module triggers a warning light on the dashboard.

Driver Information System:

The driver information system is the interface between the control module and the driver. It displays the warning messages on the dashboard and may also provide additional information such as the specific tire that requires attention and the current tire pressures.

What Should You Do When You See the Service Tire Monitor System Warning?

When the Service Tire Monitor System warning light illuminates on your dashboard, it’s essential not to ignore it. Here are the steps you should take:

1. Check the Tire Pressure:

The first thing you should do is check the tire pressure manually using a tire pressure gauge. Refer to your vehicle’s owner’s manual for the recommended tire pressure levels. If any of the tires are underinflated, you’ll need to add air to bring them back to the specified level.

2. Inspect the Tires:

While checking the tire pressure, take a moment to visually inspect the tires for any signs of damage, such as cuts, bulges, or punctures. If you notice any issues, it’s crucial to have them inspected and repaired by a professional.

3. Reset the System:

Once you’ve addressed any tire pressure issues and inspected the tires, you’ll need to reset the system. This step varies depending on your vehicle’s make and model, so refer to the owner’s manual for instructions on how to reset the STMS.

4. Monitor the Tires:

After resetting the system, continue to monitor the tire pressure regularly to ensure they remain properly inflated. Maintaining the correct tire pressure is not only important for the STMS but also for your overall safety and vehicle performance.

Frequently Asked Questions
