The top end of the technology ladder is held by a scan tool. This car diagnostic tool plugs into the OBD-II port (“OBD” is an acronym for on-board diagnostics, and the “II” designates the second generation of these ports, in use since 1996) and delivers a wide range of information gathered from your car’s computer.
You may notice a wide range of prices on these tools. Much of the price is determined by the depth of the information in its database and the way it delivers that information to you. Scan tools may be wired or Bluetooth, and often connect to your Wi-Fi network in order to access an up-to-date online database of information. In fact, newer models often have they ability connect to your smart phone, literally putting the power of computerized diagnostics in the palm of your hand.
