Understanding basic TPMS device function

Before we go on, it is important to set a basis for what we consider basic TPMS function and build from there. First off, if you’re new to TPMS tools and TPMS in general, TPMS stands for Tire Pressure Monitoring System. It is an electronic system designed to monitor tire pressure on each wheel. Essentially, this system helps monitor the state of your tires and ensure safe driving conditions.

There are two types of monitoring systems: Direct and indirect. ITPMS use the brake system and speed of the tires to determine the tire pressure status. DTPMS deliver real-time pressure readings from the sensors inside the tires.

What you should expect from a basic TPMS device

The tool should indicate the location of the sensors. It should then activate any inactive sensors and receive sensor information. This collected information should help you detect any malfunctions within the system. A basic tool should be equipped to program sensors and help you clear fault codes from the system. Some of the functions a TPMS tool helps carry out in a workshop include

  • Activating new sensors
  • Reprogramming or performing relearns on the vehicles’ ECU when there is work done on tires
  • Receive or send sensor information to the ECU after activation of sensors


The MAXITPMS TS 408 is a newer model designed to activate all TPMS sensors and perform a variety of functions including the following: Read the sensor ID, pressure, battery condition and temperature. This tool is equipped to program Autel MX sensors in addition to providing an on tool relearn procedure. Once you choose the vehicle make, model and year, this device will proceed to activate all sensors and read the necessary information. Let’s review some of the specifications that confer such functionality to this TPMS device.

Display wise, the Autel MAXITPSM TS 408 has a reasonably sized color screen that allows the user to conveniently view the data displayed on the screen. Running on a Lithium ion battery, this device promises years of service without failure. However, you will need to keep an eye on the tool to ensure the health of the battery.

The device can program Autel MX sensor wit 3 options. These include Copy by activation, Copy by Manual input and Auto-create 1-16.

How these features work

  • Copy by activation works by coping already existent sensor details to newly installed sensor.
  • Copy by Manual input whereby the user must input the id into the sensor manually after which you can find the ID printed on the original sensor.
  • Auto create 1-16 requires you to input the make, year and model of your vehicle. Once done correctly, the device will display further instruction to help the user program the sensor.

In summary, the TPSM TS408 might be simple, but it gets the job done. It has features that will assist beginner or professional fulfill their TPMS related needs.

Operation modes

Unlike the TS408, the TS508 can operate on two different modes: Quick and advanced modes. You can perform basic TPMS functions to check sensors and program MX-Sensors on the TPMS quick mode. The advanced mode on the other hand allows for complete TPMS functions diagnosis, sensor programming and position relearn.

Additionally, the 508 weighs slightly more than the 408 which some users might find inconveniencing especially for a hand held tool where ergonomic design is considered a big deal.

Factors to consider when purchasing a TPMS device

Once you decide to purchase one of these devices, for business or personal use, there are several things you must consider. Here is a quick guide to purchasing a good TPMS diagnostic service tool.

Ease of use

Because of the range of users for whom the Autel MAXITPMS TS 408 and MAXITPMS TS 508 are designed, they have easy to use interfaces. This is an important aspect of TPMS diagnostic tools. None of those great features or high level functionality will make sense if you can’t actually operate the device. Make sure to select a tool you can access and navigate without going back to the manual or scouring the internet for navigation tip.

Versatility and functionality

Depending on why you need to purchase a TPMS diagnostic tool, you may need a tool with considerable coverage to cater to many vehicles or just the scope within which your vehicle lies. A versatile TPMS tool has considerable vehicle coverage to help cater not only to domestic vehicles but also Asian and European models.

In addition to wide vehicle coverage, you want a tool that is capable of performing TPMS functions properly. It goes without saying, but a TPMS tool without exceptional basic TPMS functions might not be a good idea. Check for additional features that make your choice a better option than others and how you can utilize those features.


Disposition fees

Before you make any major purchase, the price is often an influential factor. The cost of a tool may vary depending on the model, capabilities, the manufacturer and a bunch of other factors. Don’t get confused by all the options available.

TIP: If you intend on purchasing this tool for personal use, then going for the most expensive model isn’t usually advisable. There are cheaper models available for personal use that won’t break the bank.

Ratings and customer support

Again, like with other purchases, look at the rating on the TPMS models you’re interested in. Check out what people have to say about the tool you’re interested in and how well it has served them. Apart from ratings, is would serve you well to purchase a device with good customer support. This way you can connect with the manufacturers when you need help or have an issue with your tool.

Sensors in TPMS

You’ve probably seen us mention sensors a hundred times across this article. They are an important aspect of this system. If you intend to use the device for professional use, the best option is one that reads all types of sensors. Limiting yourself to a tool that only functions with say indirect TPMS might be a poor choice especially if you need the tool for professional use. A universal TPMS tool as it is known will trigger or activate all known sensors, saving you trouble of worrying about what kind of sensors are on a vehicle.

Final word

TPMS plays an important role in driver’s safety. It is important to find an effective tool to help maintain this system.  Autel MAXITPMS TS 408 vs MAXITPMS TS 508 offers a prime example of how different tools considered ‘basic function’ TPMS diagnosis tools can be. Before you commit to one device, ensure you thoroughly research the device and ensure it is the best fit for your needs.
