GMC Service Tire Monitor System [Meaning & Reset]

The Service Tire Monitor System is a factory-installed feature that alerts you when one or more of your tires is significantly underinflated.

The system uses sensors mounted in each wheel well to monitor the pressure in each tire.

In this article, I will share what a “service tire monitor system” means, the causes, and how to reset the Service Tire Monitor System on your GMC vehicle.

What is the GMC Tire Monitoring System and How Does it Work?

The GMC Tire Monitoring System is a system that can help you keep your tires in good shape.

The system uses sensors to detect when tire pressure drops below 25% of the recommended amount. These Sensors have batteries that will last anywhere from 3-10 years. After that time, the batteries need to be replaced or the sensors will stop working.

This can help prevent flat tires and potentially save you money on gas by increasing fuel efficiency.

What Does a Service Tire Monitor System Mean on a GMC?

This message means the tire pressure sensors are out of tolerance. The service tire monitor system uses a set of sensors mounted in each wheel well to monitor the pressure in each tire.

If any one of the sensors fails, this message will appear on your instrument cluster, and an indicator light will illuminate your dashboard.

The tire pressure sensors do go out over time due to the fact that they have batteries that die after a period of time. You can have your vehicle checked at any GMC dealer or repair shop to see if they are bad and need replacing.

From my 20 years of experience as an Auto Tech, this is a common fault on GMC vehicles.

Causes of Service Tire Monitor System on a GMC?

The main cause for the “Service Tire Monitor” message to appear on your vehicle’s instrument cluster is due to one or more of the tire pressure sensors being bad.

This can happen over time as they tend to wear out, the battery inside them going out but it can also be caused by hitting something like a curb that damages them and causes them to stop working correctly.

How Do You Reset the GMC Service tire monitor system?

Now, that you know what it means and what causes it, you’re probably wondering how do you reset the GMC Service tire monitor system? Well, the answer is pretty straightforward.

In order to fix and reset the fault message you will need to replace one or more tire pressure sensors (or just one if you’re lucky). Once you replace the tire pressure sensor(s), your system will reset and you’ll be good to go.

Fortunately, GMC Tire pressure sensors are relatively inexpensive and you should get a set of 4 for anywhere between $50-120 depending on where you get them.

Obviously, if you get them at the dealer they will be the most expensive. If you get them at an auto parts store or online, they will be much cheaper.

Then you can replace them yourself but if you’re not comfortable doing that, you can take it to a mechanic or dealership. This should be an easy job and shouldn’t take more than 30 minutes to complete.

How often do GMC TPMS sensors need to be replaced?

This will vary based on different factors including where you drive your vehicle, how often you drive your vehicle, and how many miles you put on your tires.

The good news is that GMC TPMS sensors have a long life span of 3 to 7 years they can fail earlier than you expect and when that happens, your GMC will give you a Sevice Tire monitor message and you’ll need to replace the sensor.
