Chevy Service Tire Monitor System Warning: Explanation & Reset Process

What Is the Chevy Service Tire Monitor System?

The Chevy Service Tire Monitor System, sometimes referred to by mechanics as the Tire Pressure Monitoring System or TPMS, is a crucial component of your Chevrolet vehicle's internal programming. A TPMS system keeps tabs on the air pressure inside each of your vehicle's tires.

If one or more tires are over- or under-inflated, or if the system itself is malfunctioning, the TPMS system activates your Chevy Service Tire Monitor System light. To give you the most information possible with your Service Tire Pressure Monitor System, Chevrolet engineers designed three types of tire pressure alerts. Let's take a look at all three lights and what they're trying to tell you:

• TPMS Light: The monitoring sensors in your tires are malfunctioning and need repair.
• Service Tire Monitor System Warning: The tire pressure within one or more of your vehicle's tires is too high or too low and needs to be checked.
• Specific Pressure Readouts: Newer Chevrolet models may display a specific tire pressure reading for each of your tires so you can see which one needs service.

You might see one, two, or all three of these alerts lighting up your dashboard, depending on your vehicle's needs. Just like any other automaker's Service Tire Monitor System, Chevy models are designed to alert you any time your tires aren't performing at optimal levels.

If a Chevy TPMS alert has recently lit up the dashboard of your Chevy car, truck, or SUV, don't worry. By using the simple steps outlined in this guide, you can troubleshoot and resolve your issues quickly. Let's get started!

What Activates the Chevy Service Tire Monitor System?

The most common reason for your Chevy Service Tire Monitor System to activate is tire pressure that is too high or too low. Subpar tire pressure levels can lead to difficult steering and handling, reduced fuel economy, compromised payload capacity, a higher risk of blowouts or flats, or dangerous accidents, so any TPMS warning lights should be taken seriously.

Another reason your Chevy Service Tire Monitor System might light up is faulty sensors. Tire Pressure Monitoring sensors are located just inside or next to your vehicle's tires. These sensors are exposed to the force of any bumps in the road or potholes you might hit, as well as weather conditions, such as icy roads while traveling. Over time, these TPMS sensors can wear out or malfunction, which can cause your dashboard service lights to activate.

How Do You Perform a Chevy Tire Monitor System Reset?

Many drivers prefer to try a Chevy Service Tire Monitor System reset at home before visiting a service center, so if you'd like to troubleshoot the issue yourself, here are the steps to take:

• Gather the necessary tools, including a tire pressure gauge, compressor, and vehicle owner's manual. If you do not own an air compressor, you can typically pay to use an air pump at a nearby gas or service station.
• Remove the valve cap from your tire, place the tire gauge on the valve stem, and press down until you hear a hissing sound. The gauge should provide an air pressure reading. Refer to your owner's manual for optimal levels.
• If your tire is under-inflated, use the compressor to add the appropriate amount of air. If your tire is overinflated, release a small amount of air at a time.
• Recheck your tire's pressure levels with your gauge until you reach the level indicated in your owner's manual. Then, replace the valve cap.
• Check your new tire pressure by driving your vehicle a short distance, then parking, turning off the engine, and turning it back on again. If you've added or released the correct amount of air, your TPMS lights should not illuminate again.

If these steps do not resolve your issue and your Chevy Tire Monitor System light is still illuminated, we recommend bringing your vehicle in for professional diagnostics. You may have an unidentified hole in your tire that needs to be plugged, or we might need to service TPMS system sensors on the vehicle to make sure they're in top working order.
