Mileage correction tools are well-known devices that change the distance on the instrument cluster. The main question remains: are mileage blockers traceable? The shortest answer would be “NO”, however, there are several important aspects that you need to take into consideration.
There are different types of correction tools on the market that adjust the mileage of a car. Some of them can roll back the numbers, delete already existing data or extract the showing. If wanted, a person can erase as many miles or kilometers from the dashboard as he or she wants. Even though such gadgets might seem attractive, they also have several significant flaws. First of all, the system stores information about the distance in its control/storage units. Hence, erasing the data only from the dashboard is not enough and mechanics can trace and detect whether the odometer was rolled back or not. Moreover, any type of interference with the odometer that makes it show the wrong distance is illegal.
On the other hand, there is a special tool known as Mileage Blocker that does not delete or change any existing information from the system. Blockers from Super Kilometer Filter only halt the distance recording process while a vehicle is in motion. It stops counting up additional miles and its working does not affect the previous data. Furthermore, it blocks the system from saving the information in its units, consequently, the real mileage is untraceable. Plus, using mileage blockers is not illegal if you use them only for testing and tuning purposes.
Therefore, many types of tools are available on the market nowadays that change the mileage. All of them have different functions but they are illegal. However, if anyone needs such a device for testing, there is a Mileage Blocker, which stops the recording process and is also available online.
What is a car diagnostic tool?

If you wondered how can mileage blocker be detected, first you need to understand how vehicle diagnostic tools work.

Modern diagnostic testers make it easier for you by detecting and notifying exactly what problem you are dealing with.
New cars are equipped with numerous sensors and control panels that detect an issue right away. As soon as the system finds a flaw, it lets you know by lightening specific signs on the dashboard. Even though the system always tries to alert you, simple warning icons are not enough and diagnostic scanners come in. The scanner uses the data from the storage units to determine what is the exact problem. It will show everything from minor (less important) errors to complicated cases.
If you got such a tool connect it to an on-board diagnostic (ODB) port and turn it on. Based on a manufacturer the port might have a different location, so check it online to know where to plug the tool in. As soon as it’s done, it will show you the codes. Based on the car model it may show the entire information or just the codes that you should check online to understand the meaning of it. These diagnostic scanners are really helpful in detecting mileage corrections such as rollback and reset, however it is vulnerable to mileage blockers. They are untraceable and not even a professional tester can see any sign of the mileage blocker.
