“Service Tire Pressure System” is a warning message that shows up on your Jeep dashboard along with the tire pressure light.  Jeeps come with this safety feature called tire pressure monitoring system (TPMS). <\/p>\n\n\n\n

This feature lets you know when there is something wrong with the tires of the jeep to take immediate action. So without wasting time, let’s figure out what this system warning means along with the reasons for its appearance.<\/p>\n\n\n\n

What Does the “Service Tire Pressure System” Jeep Warning Mean?<\/h2>\n\n\n\n

The service tire pressure system in your jeep refers to a system in which there are TPS sensors, located in each of the tires.<\/p>\n\n\n\n

There is a TPS module that sends the signals needed for the warning when there is an issue. <\/p>\n\n\n\n

Lastly, the tire pressure indicator light is on the dashboard which illuminates and signals the issue.<\/p>\n\n\n\n

This system is a vehicle\u2019s safety feature that monitors the air amount and pressure inside the tires. <\/p>\n\n\n\n

If the system detects a lack of pressure in the tire, the system sends a warning signal and message to the dashboard. The same happens when the tire is not adequately inflated for safe driving.<\/p>\n\n\n\n

How Does the Tire Pressure Monitor System Work in Jeep?<\/h3>\n\n\n\n

The sensors in the TPMS can measure the required internal pressure in each tire. <\/p>\n\n\n\n

The proper and wrong psi for each tire is already set up inside the sensor so it can recognize both. <\/p>\n\n\n\n

Whenever the pressure drops below the threshold, the service tire pressure light is illuminated. <\/p>\n\n\n\n

Inflating your tires should be the first course of action when you detect the system warning you. <\/p>\n\n\n\n

While driving, the presence of this message means you should pull over to a gas station. Then get the air pumped inside all four of your tires for the best solution.<\/p>\n\n\n\n

5 Possible Causes of Tire Pressure System Warning Light On<\/h2>\n\n\n\n

Now that we know which component triggers this warning message, let\u2019s take a look at the possible issues that show up in a TPMS.<\/p>\n\n\n\n

1. Failure of the Tire Pressure Sensor<\/h3>\n\n\n\n

The most likely cause is the sensors in charge of the system going bad. These sensors usually monitor the pressure of the tire and send signals when the pressure drops. <\/p>\n\n\n\n

Dead batteries or driving too roughly can damage these sensors. <\/p>\n\n\n\n

Most of the time, one or more damaged sensors are the reason for the service tire pressure message popping up. It shows up when the sensor fails to do its job.<\/p>\n\n\n\n

2. Low Tire Pressure<\/h3>\n\n\n\n

When one of the four tires of your jeep has less amount of air than usual, the TPMS alerts you. <\/p>\n\n\n\n

This signals that you need to fill up the tire with air soon to inflate it again. Lack of air also leads to less tire pressure. <\/p>\n\n\n\n

So, measure the tire pressure in the jeep when the warning comes on in order to check if the tire pressure is alright.<\/p>\n\n\n\n

3. Dead Sensor Battery<\/h3>\n\n\n\n

Each of the TPMS sensors need a 3V lithium ion battery constantly. Some of the sensors might also use a 1.250-volt nickel metal hydride battery.. These batteries usually have a lifetime of 5 years. <\/p>\n\n\n\n

So, after constant use, the batteries keep getting drained. A low voltage or dead battery won\u2019t be able to run the sensors.<\/p>\n\n\n\n

As a result, there will be a service tire pressure system alert. Since the sensor batteries are fixed, you\u2019ll need to change the whole TPMS sensor.<\/p>\n\n\n\n

4. Faulty TPMS Module<\/h3>\n\n\n\n

The TPMS module is the heart of the entire system. This module is the receiver of signals sent from the TPS sensor. <\/p>\n\n\n\n

It processes the information and forwards the signal to the car computer. When the TPS module fails, the resulting error message is also Service tire pressure system.<\/p>\n\n\n\n

However, it is very rare for the TPS module of a jeep to fail. But if you have checked the other components and even replaced the sensor, then the module is likely faulty. <\/p>\n\n\n\n

5. Blown Fuse<\/h3>\n\n\n\n

There is a fuse inside the TPS module to protect the electrical system from other current flow. <\/p>\n\n\n\n

When a current more than the maximum tolerance passes through the fuse, it blows. <\/p>\n\n\n\n

So, the TPS module can\u2019t work properly. Therefore, the service TPMS light comes on as a warning.<\/p>\n\n\n\n

How to Reset the \u201cService Tire Pressure System\u201d on a Jeep?<\/h2>\n\n\n\n

Changing your faulty tire or inflating it might be enough in order to reset the service tire pressure system warning on your jeep. <\/p>\n\n\n\n

If it still persists on your dashboard, you can manually reset the message. Check out the jeep\u2019s manual for the proper instructions on how to reset this. You can follow these steps to reset the system:<\/p>\n\n\n\n
