The best part is that you can save thousands of dollars on maintenance costs! A OBD2 scanner scanner with advanced functionailities can even let you access hidden data that only a professional OBD2 scanner provides.
So let’s go back to the start and discover what exactly is a OBD2 scanner? How does it work? And what can do with it?
What is an OBD2 scanner?
OBD stands for “onboard diagnostics” and OBD2 is the most advanced version of the “OBD” technology. This technology lets you access your car’s information and in some cases even control back your car through coding.
There are many different types of OBD2 scanner that let you access your car’s OBD systems.
There are mainly 2 different types of OBD2 scanner: with a physical screen and with an app. Both of them can offer similar functions but are meant for different uses.
OBD2 scanner with a screen
Most of these OBD2 scanner, also known as diagnostic devices, offer the basic functionalities that a scan tool does. These are diagnostics and live parameters.
However, they mostly only show the raw data and you then have to interpret it on your own.
The cost for a OBD2 scanner can range from cheap to hundreds of euros, depending on the features offered. Moreover, since the device includes its own screen, they tend to bea bit bulkier. Hence they are not convenient if you are looking for a portable OBD2 scanner.
OBD2 scanner with an app
An OBD2 scanner is a small pocket-sized device that you can plug into your vehicle. They work with mobile applications so that you can view and manage all of your car’s data from your smartphone.
They can be slightly more costly because it includes a default Bluetooth connection (to make it wireless) and the mobile application must also be bought separately.
However,a big advantage is that some scanners can provide even more information than a diagnostic device. For example, besides just OBD-level diagnostics and live data, you can also code your car or access in-depth and manufacturer-level diagnostics.
Additionally, OBD2 scanners not just give you data, but also interpret for you what this information means by giving you deeper insights about your Ford Focus. This can be especially important for less modern cars where not all vehicle data can be read out via onboard electronics.
Why choose a Bluetooth OBD2 scanner?
OBD2 scanners are the most convenient tools since they are small, offer advanced functionalities, are affordable, and are wireless scanners!
However, it most be noted that every OBD2 scanner is different since they can differ in:
- Functionalities offered (basic vs. advanced)
- Compatibility with car brands
- Compatibility with smartphones (iPhone & Android)
All the features you can access with a OBD2 scanner
OBD2 scanner can let you access a lot of data about your car. Nevertheless, the available data depends on the OBD2 scanner and app that you select.
The most basic features that OBD2 scanner provide are OBD diagnostics and/or OBD live parameters. And some, only give you this information related to the engine, and not to other systems of your car.
However, there are many more features that an advanced OBD2 scanner can offer. And the best part is that “Advanced” does not mean expensive.
