Yamaha WaveRunner Diagnostics via App

Want to know what is going on with your Yamaha WaveRunner without driving to a workshop? With M-JET DIAGNOSTIC you plug the dongle into the diagnostic connector, pair your phone via Bluetooth and see what the control unit reports. You do not need a laptop.

What the diagnostics can do

• Read fault codes in plain text and clear them after the repair
• View live data such as engine speed, temperatures, intake pressure and battery voltage
• Activate ignition coils, injectors and the fuel pump one by one
• Teach idle, throttle valve and SCU
• Reset the oil change and maintenance warning, check operating hours

For 37 models from 2002

The diagnostics cover the FX, VX, GP, EX and FZ series as well as SuperJet and JetBlaster. The app recognizes what your model can do by itself: it only shows the functions your WaveRunner actually offers.
