If you own a GMC vehicle, you have noticed the “Service Tire Monitor System” light illuminating on your dashboard. This warning light is concerning, but it is important to understand its meaning and how to reset it.
The “Service Tire Monitor System” light on GMC is a warning indicator that alerts you when there is an issue with your tire pressure or TPMS (Tire Pressure Monitoring System) system.
This article will explore the meaning of the Service Tire Monitor System Light on GMC, the common causes of its activation, and most importantly, how to reset it. Whether you plan to manually reset it or use a TPMS tool, we’ll provide you with step-by-step instructions and common issues to look out for. By the end of this article, you will have a better understanding of your GMC’s TPMS and be better equipped to maintain your vehicle’s safety.
What Is The GMC Tire Monitoring System And How Does It Work?
The GMC Tire Monitoring System (TMS) is a safety feature that constantly monitors the air pressure in your vehicle’s tires. The TMS alerts you when your tire pressure is too low, potentially preventing accidents and tire damage. The system uses sensors, usually located in the tire valve stem, to measure the air pressure in each tire. These sensors send the information to the vehicle’s onboard computer, which then analyzes the data and displays it on the dashboard. If the tire pressure drops below a predetermined level, the TMS will illuminate the “Service Tire Monitor System” light on the dashboard.
In some GMC models, the TMS also provides additional information, such as individual tire pressure readings for each tire, which helps determine which tire is low on pressure. The TMS also alerts you if the tire pressure is too high, which is just as dangerous as low pressure.
What Does The “Service Tire Monitor System” Warning Mean On GMC?
If you see the “Service Tire Monitor System” warning on your GMC, it means that the Tire Pressure Monitoring System (TPMS) has detected a problem with your tires. This warning light indicates that the system has detected low tire pressure, a fault in the TPMS sensors or module, or a malfunction in the system itself.
It is important to note that the “Service Tire Monitor System” warning light is not the same as the “Low Tire Pressure” warning light, which typically looks like an exclamation mark inside a tire-shaped icon. The “Low Tire Pressure” warning light illuminates when the system detects that one or more of your tires has low pressure. On the other hand, the “Service Tire Monitor System” warning light indicates that there is an issue with the TPMS system and requires further investigation.
If you see the “Service Tire Monitor System” warning on your GMC, it is important to address the issue promptly. Low tire pressure leads to tire failure, poor fuel economy, and decreased handling, which results in accidents. It is recommended that you check your tire pressure regularly, and if you are unsure about the cause of the warning light, consult your GMC owner’s manual or take your vehicle to a qualified mechanic for further inspection.
How Do You Reset The GMC Service Tire Monitor System?

The TPMS is an essential safety feature that monitors your tire pressure and alerts you when there is an issue. If the light is on, it means that there is a problem with the system that could lead to low tire pressure, which results in tire damage, decreased handling, and potentially causing an accident.
Ignoring the “Service Tire Monitor System” warning light could also result in further damage to your tires and the TPMS system, leading to more costly repairs in the future. It is important to address any issues with the TPMS system promptly and reset the system once the issue has been resolved.
If you are unsure of the cause of the “Service Tire Monitor System” warning light or do not feel comfortable driving with it on, it is recommended to consult your GMC owner’s manual or take your vehicle to a qualified mechanic for inspection.
How Often Do GMC TPMS Sensors Need To Be Replaced?
The lifespan of GMC TPMS sensors varies depending on several factors, such as driving conditions, tire wear and tear, and exposure to harsh environmental elements. Generally, TPMS sensors are designed to last for about 5-7 years or approximately 100,000 miles before they need to be replaced. However, some sensors may last longer or require replacement earlier than this timeframe.
If you notice that your TPMS system is not functioning correctly, such as displaying inaccurate tire pressure readings or illuminating the “Service Tire Monitor System” warning light, it could indicate a problem with the sensors. In this case, it is recommended to have your GMC inspected by a qualified mechanic to determine if the sensors need to be replaced or if there is another underlying issue with the TPMS system.
It is important to note that TPMS sensors are costly to replace, and the cost varies depending on your location, the type of sensors required for your GMC model, and the mechanic’s labor charges. It is recommended to include the cost of TPMS sensor replacement in your vehicle’s maintenance budget to avoid any unexpected expenses.
The “Service Tire Monitor System” warning light on your GMC is an important safety feature that alerts you when there is an issue with your tire pressure or TPMS system. Ignoring this warning could lead to low tire pressure, tire damage, and decreased handling, potentially causing an accident. To reset the system, you can use the manual reset method, a TPMS tool, or take your GMC to a dealership or mechanic.
It is also essential to address any underlying issues with the TPMS system promptly to ensure your safety on the road. TPMS sensors typically last for about 5-7 years or approximately 100,000 miles, but their lifespan may vary depending on several factors.
