Today, most modern vehicles with complicated electronics are what makes cars super fun, these electronics are far more superior to simple car mechanics. But the main point here is OBD - on-board diagnostics. OBD diagnoses every issue with your vehicle - from your engine running low on oil, to a spring being out of place. 

More so, onboard diagnostics provide near-universal code that allows users to know what's wrong with their car, and by understanding the differences in OBD II and OBD, you can virtually address any issue that arises in your car.

What Is OBD?

As stated earlier; OBD stands for Onboard-Diagnostic. It's a system that allows external electronics to exchange data with a car's computer system. Even more, ODB specialists at recommend the installation of OBD on your car, whether it's an old or new make. OBD has become more important as cars have increasingly become computerized and the software seems to fix many problems in a car and thus unlocking performance. 

OBD was created for a purpose: mass adoption of electronics fuel injection by automakers. OBD has existed in various forms, unlike previous mechanical fuel injection systems or carburetors, electronic fuel injection (EFI) needs computer control. EFI tends to regulate the fuel flow in the engine, and it does so by using electronic signs, with this, major computers were needed to be in cars. 


In the 1990s a lot of auto manufacturers introduced computer interfaces into their cars, but this wasn't standardized until 1991. So California Air Resources made it mandatory for all cars sold in California to have some OBD capability, but CARB didn't issue standards for the system till 1994. Then OBD II was introduced in 1996 and is still in use today. 

Nearly every car sold in the USA for the last 20 years follows the OBD II standard, cars with OBD II have ports where devices can plug into and connect to a car's computer. How cool right? 

Why Does a Car Need to Have OBD?

If a car's engine isn't properly diagnosed with a proper diagnostic tool, it will cost a lot of money to fix the problem. With an onboard diagnostic, it's easy to determine a fault in a car's engine. So instead of taking your car to a mechanic to diagnose, you can use ODB to run the car diagnostic, making it important - ODB. Here is more reason why on-board - diagnostic is important; 

It Makes a Car Run Smoothly

To ensure a car runs well, it's computerized in a way that's in charge of things like fuel injection, ignition system, and other systems. So if any problems in the car occur, it informs the owner before the problem becomes serious, so it could be fixed. And with the use of a diagnostic tool, you can identify the source of a particular problem. 

It's Safe

An OBD diagnostic doesn't make you worry about glowing engine light, the scanner scans your car before you take it to the mechanic. The diagnostic tool gives you a problem code that can easily be interpreted, so if the issue is simple, it can be solved later, if it's a serious issue, it can be solved immediately by a mechanic.  

Standard Diagnosis

In previous times, it was hard to use the same scanner for different cars to make, but today things have changed. Anyone can purchase an onboard scanner, and use it for his/her car, and even more for his wife and neighbor’s car. You need not a separate scanner for a different car make.

It's Affordable

Years back car diagnostics scanners were highly specialized and expensive plus they were hard to use and mainly made for special kinds of cars. But today ODB tools are affordable and easy to use. You can easily purchase an onboard scanner as they're affordable. 

It's Easy to Use

The onboard diagnostic tool is easier to use so it's so light that you can easily hold it with your hand. You don't need any skill to operate it. All you have to do is plug your cord into your car's OBD II port, once you turn on your car, the OBD scanner will ask for your car model and engine type. Going forward you can easily follow the instructions on the screen of the ODB.

 As IoT is growing rapidly, the ODB port is still important to vehicle sustainability, health, and safety. Although compatibility and security can vary among devices.
