What is an OBD2 Bluetooth Scanner and how can it help you?

OBD2 stands for “On Board Diagnostics” and the “2” refers to the second or updated version installed on the majority of newer vehicles. Most vehicles after 1996 are installed with OBD2 computer resources that can now be accessed via an interface port underneath the dashboard that enables anybody with the right equipment to diagnose vehicle problems. Normally, this interface was exclusively for the use of dealerships and mechanics with sophisticated monitoring equipment costing thousands of dollars.

With the advance of electronic miniaturization, the power of automotive diagnostic scanners, as well as the associated cost, has allowed the vehicle owner to purchase a code scanner and diagnose their own vehicle to determine both the cause of the problem and a list of suggested fixes. Over the years, these auto code scanners have become more and more powerful in their diagnosis and repair options. Most of these units have the software needed to analyze the problem already loaded onto the device, so you just plug in the device, turn it on, fire up your car and start monitoring the results.

How does a Bluetooth Scan Tool work?

The vast array of sensors that are installed on today’s modern vehicles can give you a complete checkup of all the major functions that keep your vehicle operating at peak performance. These diagnostic scanners do a lot more than just turn off that annoying “Check Engine” light. ODB2 Bluetooth scanners are designed to communicate, via Bluetooth, with your Android Smartphone or iPhone. Additional software is required to run on your Smartphone and is sometimes provided with the Bluetooth adaptor. (Check with each manufacturer for availability). Some of these OBD2 scanners only work with Android Smartphones, some only work with the iPhone, and some work with both.

You should make sure that any model that you buy works with your Smartphone or Computer. With a OBD2 Bluetooth Adaptor, all the sensor information from your vehicle will be transmitted to your Smartphone (via Bluetooth technology), the software or App that is running on your Smartphone will interpret this information and display the results in a graphical format that you can easily understand. A recent flood of OBD2 Bluetooth scanners have entered the market, making it easier to access this hidden info.

The products vary in sophistication, some with very little in the way of analysis, while others are designed to give you a real time analysis of everything that’s happening on your vehicle. Depending upon the level of diagnostic scanning required by the vehicle owner, there are various Bluetooth scanners available that will meet your needs.
