Yamaha YZF-R125 Service Manual: Self-diagnostic function table
Access to diagnostics.
- Turn off the ignition, leave the stop / start button in the OFF position
- Press the RESET and SELECT buttons on the dashboard
- Turn on the ignition without releasing the button, wait about eight seconds until DIAG appears on the dashboard. Release the buttons
At this stage, you can switch between testing and setting CO by holding the SELECT button for a couple of seconds.
- Next, in DIAG mode, hold down the RESET and SELECT buttons for a couple of seconds and voila! test before you
Attention! do not switch between tests when the start stop button is ON. This button in testing is responsible for starting the test, and should only be turned ON if you want to run a test.
Testing:
The RESET and SELECT buttons can be used to switch between tests. The general meaning of the test is the same for all equipment, but some of the nuances of the test, namely the value of the sensor readings (for example, the percentage of the throttle position angle) - may vary - check the data in the service manuals of your equipment
To run the test you want, move the engine start switch to the ON position
