The cord from the reader, will plug in to your diagnostic port as shown below. many times the plug has a cap on it, that will need to be removed first. The plug is normally around the battery and ecu area. Refer to your owners manual for location, if needed
The lights need to be lit up on the reader, for it to be able to connect to your phone. You may need to have the bike running for this
To link to the reader with your phone, you will first need to download the ELM 327 app. It looks like this and says " car scanner" on it. Any other app won't work
After the app is downloaded and on your phone, and the bike has the reader powered up ( lights are on ), you'll make the connection. Go into settings on your phone and the into WI FI. If your phone is connected to to your home WI FI, you will probably have to disconnect from it. Then you can connect to the OBD 11 and you should get a check mark.
Now just open the app and click connect. The phone should pick up the signals and connect within 30 seconds.
You can click on " all sensors" or "live data" and get real time numbers, like running rpm. you can adjust your rpm or see your water temp and other things
You can also go to " diagnostic codes" to read codes and erase them. There are also the other functions you can check as well. You can upgrade the app, to even get more functions
