Automotive Scan Tool – Automobile Diagnosis Made Easier

Remember the days when diagnosing a problem in your car used to be a pain? You had to take it to a mechanic and pay money just to find out what was wrong with it. Ever since the advent of the automotive scan tool, it is no longer the case. You can check your car yourself and determine what is wrong with it in no time. Such a tool is indispensable for any car owner, especially in a vast country like Australia, where car is the primary mode of transportation.

What Is It?

An automotive scan tool is designed to diagnose the problem in an automobile. It does so by interacting with the OBD (On-Board Diagnostics) system, which is also known as the onboard computer.

The Way It Works

Whenever there is a problem with your brake, engine, or any other component for that matter, your car’s OBD warns you by flashing a warning light. When it does, you can use a scan tool to find out what the problem is. The tool interacts with the OBD, reads the data, and lets you know what exactly the problem is. It usually indicates the problem in the form of a trouble code, which you can interpret using the manual that comes with the tool.

The Many Functionalities of an Automotive Scan Tool

There are many different types of scan tools available on the market today. They differ from each other in terms of built-in features and functionality.

The basic code reader type tools can interact with the OBD and list the trouble codes. You can interpret the codes and find out if the problem requires immediate attention or can be dealt with later.

Bi-directional scan tools, as the name indicates, can not only interact with the OBD and list the trouble codes, but also communicate back with the onboard computer and perform certain functions. Using these tools, you can switch on the headlights, activate the trunk release function, or disengage and deactivate some of the systems in the car.

Apart from listing trouble codes and communicating back and forth with the onboard computer, advanced scan tools can do so much more. For instance, in many cars, whenever you do a physical repair, you are also required to reprogram the onboard computer and command it to relearn the limits of the newly repaired or replaced component. Otherwise, even if the issue has been resolved, the onboard system might refuse to acknowledge it and not function properly. You can easily avoid this problem with the help of a scan tool that is capable of doing programming and calibration procedures.

A high end automotive scan tool can also capture, store, and play back live data. This is a crucial feature that can help you immensely. For example, if you want to test drive a car and find out how a particular system performs, you can use this tool to capture the specific sensor output readings you want.

Yet another important feature of high end scan tools is that they have a knowledge base. These tools not only list out the trouble codes, but also give you suggestions and tips as to what you can do to fix the issue. Such information is vitally important, particularly when you are dealing with a problem that you have never encountered before. At such a time, troubleshooting instructions could help you resolve the issue faster and save you a lot of time.

Many high-end tools also allow you to attach an external device like a gas exhaust analyzer or a lab scope. It not only extends the functionality of the tool, but also gives it a lot of additional value.

Choosing an Automotive Scan Tool

You need to choose a tool depending on your needs and budget. Low-end tools are budget friendly and can list out trouble codes, using which you can diagnose the problem. High-end tools are generally expensive, but they are well worth spending your money on as they can make diagnosing and fixing your car’s problems ridiculously easy. They can read and list out trouble codes and tell you what the codes mean and what the problem could be. From capturing and playing back data to performing re-learn functions, they can pretty much do it all.
