What it means: An input fault tied to the throttle, battery, or display — often something as simple as an unexpected button combination.
How to fix it:
- Release any pressed buttons. Pressing multiple display buttons at once (or a stuck button) can trigger Error 22 with nothing actually wrong. Let go of all buttons and see if it clears.
- Unplug the throttle. If you weren't mashing buttons, disconnect the throttle. If the error clears, the throttle is the culprit and should be replaced.
- Look at the battery and display. If unplugging the throttle doesn't help, the issue points to the battery or the display — contact support to isolate which one.
