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.
Below we will list all the functionalities that a OBD2 scanner can let you access! In the case of the Carly OBD2 scanner, you can get all of them.
Diagnostics for Ford Focus
The diagnostics functionalities allows you read out and clear fault codes that are present in your Ford Focus.
OBD diagnostics are generic faults related to the engine only (i.e. check engine light). Whereas, manufacturer-level diagnostics are fault codes related to all of the other vehicle systems, such as the airbag, transmissions, brake, ABS codes, etc.
Having access to the diagnostics features lets you access an overview of your car’s health and find out potential issues that can become critical. Some OBD2 scanner such as Carly can even let you access both generic and manufacturer-specific trouble codes.
Live data for Ford Focus
Having access to a live data feature lets you see the real-time parameters of your vehicle! Here you can monitor data such as the fuel consumption in l/100km.
Similar to diagnostics, some OBD2 scanner let you access only OBD live data and others also let you access manufacturer-level live data.
OBD live data refers to engine-related data only. While manufacturer-level live data refers to real-time parameters about other systems than the engine.
Used car check for Ford Focus
The used car check is one of the most useful features if you plan to sell your Ford Focus or purchase a used car. With this feature, you can detect car scams by uncovering:
- Mileage fraud

Cost of OBD2 scanner

Many OBD2 scanner can only check certain systems, and give you basic engine-level obd2 faults. However, the more advanced OBD2 scanner can give you insights into other systems of your Ford Focus. Usually, professional software that offers this level of in-depth data can cost up to $3,000.
However, with Carly, you can get your OBD2 scannerand app with advanced features for approximately $130.
Are cheap OBD2 scanners any good?
It is possible that you run into budget scanners while searching for one. However, we highly advice you to be careful about purchasing a cheap diagnostic tool.
In many cases, they are not reliable or require extremely expensive control software. And additionally, software updates or additional functions are only available for a fee. So in the end, you end up spending a lot of money.
What should I look for in an OBD2 scanner?
In essence, what you should look for in a OBD2 scanner depends on what you want and need.
For example, if you are only looking to read and clear engine trouble codes (such as the check engine light) then a simple code reader will do! And, if you are looking for other features such as coding and live parameters, a complete OBD2 scanner such as the Carly scanner works best.
Nevertheless, regardless of what you are looking for, we have a checklist of suggestions that you should look for before buying your scanner.
