There are a lot of people who are asking the question, “What is the OBD System?” Well, OBD systems are also known as On-Board Diagnostics systems.

These are what monitor the overall status or health of your car’s engines, as well as its electronic sensors and emission control systems. In 1996, a new set of standardized regulations was implemented, which then gave birth to the OBD-II.

What is the OBD System?

The OBD-II system is an improved system diagnosis regulation of the previous OBD system. This now features a catalytic converter which ensures that all of the processes and functions of your vehicles are kept properly functioning and maintained to the highest standards.

What happens when a problem is detected is that a warning signal is displayed on the dashboard. This malfunction indicator is then lit up to alert and notify the driver of the vehicle. OBD systems are vital to the overall well-being of a vehicle because it detects potential problems.

This, in turn,prevents the car from experiencing more serious problems. Examples of avoidable car issues are poor fuel economy and high emission rates. Thus, OBD systems will not just benefit one’s car, but will also help the driver save money from the expensive repairs.

The Importance of OBD Systems

There is no doubt that four-wheeled vehicles are one of the biggest contributors to the air pollution that the world is currently experiencing. If ever a car emits too much smoke together with all of the different engine noises it makes, there is only one answer to that, and that the car is not anymore that efficient.

Fortunately, OBD-II systems come in the equation, because these are the ones that keep and maintain the optimal strength of the vehicle. It not only makes sure that it runs efficiently, but it also ensures that the vehicle is environment-friendly.

Knowing the actual state of your vehicle is crucial to the driver and passenger’s safety, which is why it is highly recommended for you to have your own OBD-II diagnosis tool. These also ensure that the vehicle maintains its responsiveness, ensuring that the driver experiences the best driving conditions possible.

OBD diagnostic tools also provide you greater control over your car, as this ensures that you know any problems before they become serious issues.

It is the best way to avoid any unnecessary and complicated issues on your car. The main highlights of an OBD-II diagnostic tool are that it features live data gathering from the different parts of the car, as well as enables the driver to reset the airbag if ever it gets used.

You will also quickly know the real status of your vehicle because you will be presented with a detailed graphical presentation of the different issues that you have to face regarding your car. Analysis and maintenance have never been easier.

Knowing the Terminologies

When dealing with OBD-II systems, it is also important to understand the different terminologies that are used with it.

1.  Engine/Electronic Control Unit (ECU)

The ECU is the main part of the car’s electronic systems. It is the one that controls all of the electronic components of the car, making it a very vital part. Because of this, it is usually referred to as the brain of the car. This is the one which monitors and control the different functions of the vehicle.

Most ECUs these days are reprogrammable, which means that new updates can be added to it every now and then. This is very useful if the driver of the car wants to modify some aspects of the car.

2.  Diagnostic Trouble Code (DTC)

The Diagnostic Trouble Code are the ones that notify the driver where the problem of the car is. It is the one that defines the issues that need to be fixed.

However, these codes vary from one car manufacturer to another, which is why it is recommended that the OBD-II diagnosis tool that will be purchased will be capable of reading multiple DTCs from different car models and brands.

3.  Parameter Identification (PID)

The Parameter Identification is the information that one obtains from an OBD-II system. Thisis also called as PID, and these are the ones that give the driver the parameters that they can check out regarding the overall status of their car.

However, it is important to know that there are some PIDs which aren’t supported in other vehicle protocols. This is because each car manufacturer usually has its own unique and custom PID.

4.  Malfunction Indicator Lamp (MIL)

This is the one that can be seen on the car dashboard. It notifies the driver if there are any problems in the car. This is very helpful because it warns the driver ahead of time not to continue driving. Undeniably, the MIL can indeed save a life.

Final Thoughts

It is an undeniable fact that safety and security are two of the most important things that a driver must always remember when driving or maintaining a car. Thankfully, OBD and OBD-II systems and diagnosis tools are here to stay.

These not only ensure that you are safe from all of the possible accidents that may happen due to some minor issue that worsened, but it also helps you save money because it stops you from spending more money on aggravated problems.

Apart from that, OBD-II systems ensure that your vehicle maintains its efficiency and ensuring that all of its functions work properly. It also gives back to the environment as this makes vehicles more environment-friendly.

If you are one of the people who want to have the peace of mind when driving, or if you want to make the most out of your car, then what you need to do is to have your own OBD-II diagnosis tool, for this assures you that your car remains to be
