During my debacle of disconnecting my throttle position sensor I found the following info that may be useful


How To Read Service Codes:

Turn on ignition.
Push the upper meter button to display the odometer.
Push the upper meter button and left meter button for more than 2 seconds.
The service code is displayed on the LCD instead of odometer. Multiple codes will be displayed in a sequence with the interval of 2 seconds.
Turn on/turn off the ignition to return the display to the normal operation mode.

How To Erase Service Codes:

Turn on the ignition and start the engine.
Keep the idling more than 30 seconds.
Run the bike for more than 5 minutes at a speed of 25 mph or more.
Stop. Turn the ignition switch off.
Repeat the above procedures 3 times.

@Daniel DC
Welcome to the forums!

Please fill in your profile to include your bike/location info and that
is easier using a PC vs the app. This will help others answer questions you may ask knowing what year and model bike you have.

It's usually pretty easy to find the Kawasaki service manuals (SM) online. I suggest poking around to find one so you have it on hand in the future. All that sort of stuff and more will be in the SM.
