5 Best Bluetooth OBD2 Scanners to Diagnose Any Error Code

With modern cars slowly turning into computers on wheels, reading DTC codes and analyzing live engine data is essential for most serious troubleshooting tasks. And for that, you’ll need an OBD2 scan tool. Unfortunately, professional scan tools are often quite expensive and usually come equipped with extensive features that you don’t really need if you only want to know why your check engine light just popped up in your dashboard.

Luckily, Bluetooth OBD2 scanners are usually much cheaper and frequently offer more than enough features for most people. However, with the high number of models out there, it’s easy to get a bit lost and end up buying a cheap Chinese knock-off that will only leave you disappointed.

To help you find the right one and save some money on car repair bills, we’ve come up with a list of the best Bluetooth OBD2 scanner currently on the market. Keep in mind that some of them are better suited for beginners and weekend DIYers, while others, usually the more expensive ones, are only worth it if you work in the field.

In all cases, make sure to evaluate your budget and needs before you start shopping around. After all, the only thing worse than buying a tool that doesn’t do what you expect him to is paying too much for something you will never use anyway.

Why Do You Need a Bluetooth OBD2 Scanner?

All modern cars have various onboard computers monitoring a wide range of parameters and ensuring optimum performance and safety at all times. If some of these parameters go out of a specific threshold, the system warns the driver with the appropriate warning light.

When that happens, a specific code that can help pinpoint the problem will be stored in the vehicle’s memory. On-Board Diagnosis, or OBD in short, is a unified protocol that stores these codes in a specific format. As a result, every code will have the same meaning in any car, regardless of make or model.

However, access to these codes is only possible using a special device called an OBD2 scan tool that connects to the vehicle through a dedicated port. Dealers and professional workshops use various diagnostic tools for this purpose, but these tend to be quite expensive. Still, Bluetooth OBD2 scanners are much more affordable options, making them suitable for non-professionals.

Frequestly Asked Questions (FAQ)

What is OBD2?

OBD stands for onboard diagnosis, which is a common language that makes the communication almost identical on all cars. Despite their differences, all modern cars have an electronic infrastructure that operates on similar principles. On one side, there is a range of sensors that measure an incredibly wide range of data.

The onboard computer uses these values to determine how different systems are running and decide on appropriate actions. If any of these values are out of the predetermined range, the system will store a specific 4-digit error code within its memory, making it easier for mechanics to identify the culprit and fix it.

Which cars use OBD2?

The usage of the OBD2 standard began in 1996 to improve fuel economy and reduce emissions but also to make fixing cars that were becoming increasingly complicated a lot easier. Still, there are variations between makes and models, as manufacturers implemented this technology at different times. This is why there is no simple and definitive answer to which cars use OBD standards. However, gasoline cars made after 1996 and those with diesel engines made after 2000 are all OBD2-compliant.

What can Bluetooth OBD2 scanners do?

Despite their simplicity and affordable price, Bluetooth OBD2 scanners are a reliable way of getting an insight into vehicles’ running parameters. Although there are different models available on the market, all of them work on the same principle. Connecting them to the vehicle will give users access to stored error codes and live data. While basic models are limited to drivetrain modules and their parameters, more advanced ones can also communicate with other systems.

Where do these scanners connect to?

All modern cars have something called an OBD2 port, a standard socket for connecting a diagnostic tool. In most cases, this port will be easy to find somewhere under the dash, usually on the left side, sometimes on the right, sometimes near the fuse box—it depends. However, some manufacturers choose a different location, which can make things a bit more difficult. The OBD2 port may be hiding in places like the glove box or behind the ashtray in those vehicles. That being said, if your car was produced after 1996, there’s one somewhere.

If you can’t find it, consulting the user manual or performing a quick Google search should reveal the exact location in a jiffy.

What is the difference between scanners and diagnostic tools?

Most modern OBD2 scanners are capable devices that can do more than just reading error codes. Still, even the best among them have their limitations. Although being more expensive and complex, diagnostic tools are far more powerful machines. Besides standard functions that are similar to scanners, they can run test procedures and perform various adjustments. But unless you are a professional auto mechanic working 40-hours a week in the shop and do extensive fuel injection tuning, for example, you don’t really need a full-fledged diagnostic tool.

Verdict

As we have shown in this article, there is a wide range of scanners with different features available on the market. Capable devices like the BlueDriver Bluetooth Scan Tool will access all vehicle systems and stored codes. Although other scanners may have specific limitations, they are usually cheaper and can still be more than enough for most users. On the flip side, certain devices like the Autel AP200M will provide original equipment-level features, such as the ability to run a comprehensive all systems scan along with other commonly-used functions.

In all cases, make sure to correctly evaluate your budget and needs first. But as a general rule, if you aren’t so sure which one you should buy, get your hands on the BlueDriver or FIXD models—they won’t disappoint!
