Segway scooter communication cable repair and replacement
The data line between display, controller and battery

What it does and when it needs service
The communication cable carries data between the display, the controller and the battery, and part of it runs through the folding stem. Loose or bent pins, water, corrosion or a cable pinched by folding can black out the display, shut the scooter down mid-ride or trigger communication errors. We find the fault by testing each connection in turn.
Symptoms
- The display stays dark or flashes
- The scooter shuts down while riding
- A communication error on the display (e.g. 10 or 21)
- The problem appears or clears when you fold the stem
If you notice one of these, pick it in the service request and your request starts with this part.
