Buying Guide – Types of Bidirectional Scan Tools


There are two major types of bidirectional scan tools available in the market today. They are mostly responsible for delivering you the accurate scan results. However, the types mainly depend on the year of manufacture and work of the scan tool.

You must pick the right type of model that goes well according to the manufacturing year of your car.

OBD I

The OBD I type of tool is the primary type of scanning tool that was used in early cars. It used to scan up all the related health and technical details of the car as per your requirement.

However, it used to be discontinued from 1996 because of a lack of severe upgrades in the system. If your car was manufactured before 1996, you may need to find OBD I type of scan tool.

OBD II

The OBD II is the latest type of bidirectional scan tool available in the market today. It is now used for most of the cars and vehicles that are running on the road.

It was introduced after 1996 with severe upgrades that can decode the technical faults in your car. By far, it is one of the most advanced types of scanning tools that will help you to find the accurate results.

Factors to Choose Bidirectional Scan Tools

There are several factors that you need to consider before choosing the best bidirectional scan tools. Here are some of them:

Compatible

Before you buy any scan tool, you need to ensure that the device is compatible with the vehicle or not. So you need to go back to the year of manufacture and then try to form the bidirectional tool. You need to figure out which one is compatible with the OBD I or OBD II.

Check Light Engine

Another important factor that you need to consider is the ability to diagnose the engine light. The scan tool must also have the ability to diagnose where the problem lies and where it is going all wrong. If you find that it rectifies the check engine light, you will be able to change the light engine back to normal.

Response Time

If you get a device that performs well with a quick response, it is highly versatile. Try to opt for a product that features a high-performance module in the shortest period. Make sure that it is fast and reliable and it is accurate enough.

Recording

Another important feature that you need to consider is the recording of the data that is being collected. Some models show you the live data transmission through graphs. Having such will help you to gain the timeline data according to the plan that is been set up.

Test Options

Another important factor that you need to consider is the test options available for you. There are multiple test options that you need to figure out like EVAP test, oxygen sensor test as well as the other test options like a smoke test. If you get a device that performs all the tests, there cannot be a better catch.

Frequently Asked Questions


  1. How much does an OBD scanner cost?

    Now this will entirely depend on what your preferences are. You may get even some of the products that will have the least pricing and then other products that will cost you more than $1000. So make a checklist for the requirements and then you can easily sort out the needs.

  2. What is the difference between OBD and obd2?

    The OBD is practically the connected console of the vehicle. It is a specific scanning tool that will help you to easily feature the diagnostic results at the earliest. The OBD 2 is much more advanced than the first generation models that will help you to diagnose with more accurate results.

  3. Is it worth buying an obd2 Scanner?

    Getting stuck in the model of a road is never a good example of how you should run the vehicle. But an OBD 2 scanner and its daily running tests will help you to easily find out the preferable choice. It hardly takes up a few minutes to complete the setup and run the vehicle. So yes, it’s, of course, important to have this product.

  4. Can you drive with OBD plugged in?

    I don’t feel that you will have any problem driving the vehicle while the scanner is being plugged in. However, this will depend on the maker of your model. If there is space left to keep your legs while the device is plugged in, it will never be an issue.

  5. How Do I Know Whether My Car is OBD-II Compliant?

    Now, this is the most important part of using the product for different means. You can easily get to know if your car is OBD II compliant or not if you know the model and the year of the manufacture. Usually, cars above 1996 manufactured in the USA are all compliant to the OBD-II mechanism.
