Motoscan Adapter Turns Your Smartphone Into a Diagnostic Tool for Harleys

A new plug-and-play adapter has hit the market that can turn a smartphone into an on-board diagnostics device for Harley-Davidson motorcycles.

Claiming to be the first of its kind, the Motorscan adapter connects to the diagnostic ports found on 2001 and newer Harleys. The adapter sends information to a app, relaying trouble codes, and other diagnostic information to a Bluetooth-enabled Android or Apple device. Trouble code reports can saved or shared via email, so owners can have their own copy or send it to a mechanic.

“We created the Motorscan OBD adapter so that Harley-Davidson owners can easily diagnose their bikes themselves and see what is wrong if the check engine light comes on,” says Alex Leonov, Managing Partner at Smart Vehicle Diagnostics LLC. “You can save time and money on unnecessary shop visits, but you will also know when you actually must visit your mechanic.”

The Motorscan adapter is small enough that Leonov says it can be left plugged in to a bike.

“A lot of diagnostic tools are bulky, but we wanted to make a tool that can be left in a bike and used every day,” says Leonov. “We ended up reinventing the OBD adapter when we created the world’s smallest diagnostic device for powersports with a patent-pending design that is guaranteed to fit snugly into a bike’s diagnostic port. To ensure software compatibility with a wide range of Harley-Davidson models, we partnered with EOS Srl, makers of professional motorcycle diagnostics equipment. The end result is an easy-to-use tool to monitor your bike’s health daily.”

The adapter is available in two versions, a four-pin adapter for older models with Delphi engine control units and J-1850 OBD connectors or a six-pin adapter that works with the CAN-Bus connectors found on newer Harleys.

The Motorscan adapter is available online at, for $299. The app is free to download on iTunes and the Google Play store.
