Most enthusiasts will agree that their car is part of the family. We all love our cars and the relationships we can build with them, but modification is what we do.

As technology has hit its stride in recent years with a variety of traditional options in the market, one such professional yet unique device is an OBD2 adapter that pairs wirelessly with your Android or iOS smartphone and has made possible for everyone to get access to information regarding fuel efficiency, diagnose check engine lights, and gather a ton of other useful data making your driving experience more connected and enjoyable.

What is an OBD2 adapter?

  • An OBD2 adapter is also known as a vehicle interface adapter is an electronic device that allows a computer to access the vehicle network. It is similar in operation to a computer modem or a gateway, in that it translates messages from one protocol to another.
  • The adapter plugs into the car’s OBD2 port and enables various functions such as performing diagnostics, resetting fault, reading live engine sensor data, or even customizing the car’s configuration.
  • Apps that usually connect to an OBD2 adapter in one of three ways:
  • Bluetooth to Android.
  • Bluetooth Low Energy (LE) to iOS and Android.
  • Wi-Fi to iOS and Android.

The most common type of OBD2 adapter is an ELM327 adapter. This can work with most of the apps on Android and iOS smartphones.

ELM327 is a communication standard that defines how an app can communicate with an OBD2 adapter with the vehicle.

How to choose an OBD2 adapter?

While choosing an adapter, you must consider the following things like:

  1. The platform you plan to use such as iOS, Android, or Windows.
  1. The type of adapters such as Bluetooth or Wi-Fi.
  2. The features supported by the adapter such as MS-CAN, size, and upgradeability.

The adapter type depends on the platform you are using. For example, if you are using an iPhone or iPad then you will be limited to Wi-Fi or Bluetooth LE adapters.

In general, we recommend Bluetooth LE for iOS, Bluetooth for Android, and USB for Windows.

However, you will need to consider your specific requirements before you make a decision.

How to use an OBD2 adapter?

  1. Once you have decided which type of adapter you want to use, then you will need to plug it into your car.
  1. The port may be in different places depending on your car’s model, but it’s legally within two feet of the steering wheel. Usually, it’s just underneath the wheel, or near the fuse panel. Once you find it, plug the adapter in that port.
  1. Next, open up your phone. Pair up your phone with an adapter via Bluetooth.
  2. Find the OBD-II adapter in the list of devices and then tap on it.
  1. Enter 4 digit pin in your phone that is labeled on your adapter. Once you have entered the pin tap on ok and check your adapter in the list of devices.
  1. Once the pairing is complete, allow the phone to connect to your vehicle’s Electronic Control Unit (ECU). Click on read fault codes. If your check engine light is on, you will get a diagnostic trouble code and a description of what it means. You can also monitor the readiness status to see if your vehicle is ready to pass the emission or smog test.
