Introduction To Car Diagnostic Tools : Details & Benefits

Introduction :

The most recent improvements in modern cars have thus far circumvented round the incorporation of a significant amount of technology into the car, like the inclusion of output sockets for powering appliances, front and rear cameras for more accurate parking, dash cams, and other accessories.

However, the most significant improvement comes from a need to easily diagnose and fix the problem with a vehicle , hence , Car diagnostic tools were introduced to solve this problem.

Car Diagnostic tools are also known as On-board-diagnostics (OBD), which is an automotive term that describes the vehicle’s self-diagnostic and reporting capability which give their owners or repair technicians with access to them the status of the various vehicle sub systems.

Features :

For a very long time before the EPA’s mandate in 1996, cars of different brands had different diagnostic processes and this was a real bother for both car owners and repairers. OBD I was in use back then, and it was specific to each vehicle and model. However, since the mandate, all cars have been designed to be compatible with any standard diagnostic tool or vehicle scanner.

With this, a car owner can buy any diagnostic tool and use it on any car of his choosing and still get a standard diagnostic run on the vehicle.

The car diagnostic tool is characterized by providing more information about the state of the car to the driver without having to go to the mechanic, or paying extra fees at the auto shop for inspection and fixing. A more detailed example is how the vehicle informs the driver if the wheels are not aligned by displaying the message on the dashboard in however form the manufacturer sees fit to design it.

This by far is one of the most important additions to the vehicle concept in modern day improvement schemes.

Benefits of having a Diagnostic tool :

Here are the benefits of having one in your tool set :

1). Provision of a comprehensive scan of the vehicle’s electronic systems:



With a car diagnostic tool, there are computers in charge of the systems, monitoring their state and reporting any issues. The sensors placed in different parts such as the ignition system, the fuel injection and the automatic transmission among other parts, such that they gather and transmit data to the main computer module of the car where it is displayed for the user to see.

This allows for a precise monitoring and control of the car’s systems which as an extension conserves energy, maximizes power and increases system efficiency of the vehicle. It uses complex codes to detect the source of a potential issue and alert the driver before it becomes too serious. Since they are designed to report said issues instantaneously, a lot of money and time is conserved, making your investment worth its salt.

2). Peace of Mind and Confidence :

For long distance travels, one of the most impending bothers on the minds of drivers is the probability of having car issues on the way. Car diagnostic tools basically put their minds to rest and give them more assurance about their journey by running a full system diagnostic which informs them whether the vehicle is good to go or not.

In such cases, when powertrain control module of the car receives data from the car’s sensors, the engine light comes on. However, while the PCM may be able to compensate and help your car function normally, you would be aware of the problem at hand and deal with it as soon as you can.

3). Ease of Use :

The diagnostics process involves troubleshooting every accessible part of the vehicle, scanning for problems and informing you about them. Considering how technical this process is, it requires a certain level of technical knowhow and time. The convenience feature that comes with the use of car diagnostic tools is that all of that is done for you without any knowledge or currency requirements from you.

After inputting the vehicle identification number (VIN) as well as other information such as the model, make and engine type among other things, the rest is done for you. After this, you just have to follow instructions that would be displayed on your screen to conduct the scan, the necessary information about the state of your car is displayed in real time.

4). Affordability and cost effectiveness:

Before the OBD II standard was imposed, the diagnostic tools were invented for specific cars and models, and varied in cost according to the rating of their vehicle on the market. Then, diagnostic tools were a major determinant of the vehicle one could afford.

Recently, the scanners and diagnostic softwares are much more affordable and just as effective as the OBD I brand-specific ones. There are multiple language options too, as well as other convenience features that ease its use. If with these options it’s still outside your price range, you could borrow from a relative or friend and run the scan.
