5 Best Bidirectional Scan Tools For Your Car

Are you looking for a bidirectional scan tool? Don’t need to worry now! You just have come to the right place. In this article, here will be discussing the best bidirectional scan tools available in the market. We have jotted down some of the best options available for you. Here we will explain how they can create a strong impact on your work. Before going further, let’s discuss some fundamentals that are needed for you to understand.

What is a Bi-directional Scan Tool?

A bidirectional scan tool is a powerful tool in the world of vehicle repairing. It is a diagnostic mechanism that allows sending commandments. This factor makes it quite different from traditional scanning devices.

One key difference is that the bi-directional scan tool can issue commands from the service center’s computer to the car’s engine control unit (ECU) or Electronic Control Unit.

Moreover, it can also make a request from the ECU to bring information from the car itself. In contrast, typical OBD2 scan tools only have the ability to read data from vehicle diagnostic link connectors and send them back to a personal computer. And they do not have the ability to read data from a vehicle’s ECU or Electronic Control Unit.

The main purpose of a bi-directional scan tool is the same as other types, which is to collect all kinds of information from cars and trucks. In addition, it can also perform functions such as activation of electronic control units within the car. And it is able to streamline the diagnostic process.

Main Functions

  • Running different system sets simultaneously
  • Accessing the engine control module
  • ECU Coding facility

Differences between Bi-directional vs. Normal scan Tools

We will discuss the bi-directional scan tools in detail later. Let’s discuss the highlighting and limiting features of it.

Bidirectional Scan Tool Normal Scan Tool
User friendly but a little tough for mere beginners. User friendly. The best option for beginners.
Advanced features such as Programming, ABS, SRS, Key fob, etc Basic features such as Real-time data, extracting time-freeze information, etc.
Pricier. Affordable.
Information transmission functionality is present. A normal scanner has only the ‘Read-Only’ option. It can’t transfer information.

How does Bi-directional Control Work?

  • Bi-directional functionality works best for multifunctional properties. It uses one of the best hardware mechanisms that expertly handle the two-way flow of information.
  • For example, one can easily perform tests on their vehicles without even getting in. It is easy to check how the car responds to different command sets. Thus identification of errors becomes easy.
  • A bi-directional experiment device works with the aid of utilizing specialized hardware. Because of this, the individual using the device can without a doubt command the car to carry out numerous capabilities. It includes beginning the throttle or powering the ignition.
  • It leads to mechanics performing without difficulty, running assessments on their motors without getting inside the driver’s seat. They can stroll around the auto simultaneously. It helps the bi-directional experiment device to peer precisely how the car structures respond.
  • As a result, a technician can pinpoint issues and troubles within a car while not applying a tedious trial-and-blunders approach.

What to look at before buying a Bidirectional Scan Tools For Your Car In 2022

Now you know what a bi-directional scan tool in detail is. What’s in trend, comparative analysis, and everything related to it is in your check. Sometimes, we get confused while choosing what we want. Moreover, the programming & scanning in a scan tool goes hand in hand. And when there are several options available in the market, it gets difficult sometimes to select the best option for yourself. So, we have jotted down some useful points to help you make the right decision.

  • Firstly always check the compatibility of your desired scan tool. It is one of the desirable standard systems that help the external systems in line with the computer system. Mainly for compatibility, you have to check amongst the two scanners only, i.e., OBD I and OBD II. These days only OBD II is in trend, and the former one is quite outdated.
  • The second thing to check is the average response time of the machine. You may check how much your diagnostic tool lags or not. If your system has a longer duration of response time, so the entire diagnostic process would get delayed. It would lead to back-to-back faults. You will always need a fast and prompt-response giving scanner.
  • The third thing to check is to maximize the user’s safety level. You should check how efficient the anti-lock braking system is. Moreover, how it works in all situations. Moreover, how the full safety restraint system responds to different situations. It should have some safeguarding techniques to deal with accidents. Most importantly, how the verification options should be prompt too. In a good scanner, multifunctional options should work smoothly.
  • One of the last things to consider is Coding. It comprises a large and broader part of the control engine module. It alters the vehicle’s settings. A module’s overall performance can be tweaked, remapped, coded, or programmed as per its designated specifications. Likewise, coding and programming provide an in-depth perception of the vehicle system. It helps the technicians troubleshoot and resolve complex care issues.
