Battery and electrical safety. Lithium-ion batteries can catch fire if they're damaged or charged wrong. Never open a battery pack, and stop using any battery that's swollen, hot, wet or smells burnt. Every edit to this page is checked by a second person before it goes live.

This page covers the Segway Ninebot eKickScooter E2 Pro (model 051405U). When it finds a fault the dashboard lights its error icon, and the Segway Mobility app shows the code and likely causes (E2 Pro product manual). Segway's self-test manual also gives a beep pattern for each code, a number of long beeps followed by short ones (E2 Pro self-test manual). The codes below follow that self-test manual.

A code that points at the motor, controller, wiring or battery is an electrical fault. Do only the plug checks on this page, with the scooter off, and leave opening the motor, controller or battery, soldering or rewiring to a pro or the maker's support. See battery won't charge and when to call a pro.

Codes

  • Error 10 (1 long beep): dashboard communication abnormal. With the scooter off, check the dashboard harness and reseat its terminals.
  • Errors 11, 12 and 13 (1 long, 1 to 3 short): controller malfunction. Contact Segway after-sales.
  • Error 14 (1 long, 4 short): finger throttle hall abnormal. What to check
  • Error 15 (1 long, 5 short): brake lever hall signal abnormal. What to check
  • Error 18 (1 long, 8 short): motor hall sensor abnormal. Segway's first check is the motor to controller connection inside the deck, with the scooter off, which is best left to a shop.
  • Error 21 (2 long, 1 short): battery communication error. The battery to controller cable is the first check.
  • Error 23 (2 long, 3 short): abnormal battery condition. Check battery condition in the app under vehicle details.
  • Error 35: controller malfunction. Contact Segway after-sales.
  • Error 39 (3 long, 9 short): abnormal battery temperature. What to check
  • Errors 40 and 45: controller malfunction. Contact Segway after-sales or an authorized service provider.
  • Error 42 (4 long, 2 short): motor not calibrated. What to check
  • Error 50 (5 long): motor abnormality. The motor harness connection is the first check.
  • Error 51 (5 long, 1 short): controller overvoltage, which Segway links mainly to chargers not made for the scooter. What to check
  • Error 52 (5 long, 2 short): motor can't rotate. Segway tests with a known good motor before replacing it, a service job.
  • Errors 53 and 54 (5 long, 3 or 4 short): controller overcurrent. Power off, let it rest, and keep the load within the limit in your manual.

Before you call a shop

  • Connect the Segway Mobility app to read the exact code, and update the firmware to the latest version (E2 Pro product manual).
  • Power off and restart once. Check that the throttle and both brake levers spring all the way back.
  • Charge only with the Segway charger made for the E2 Pro.
  • In heat or cold, let the scooter stand in a room within the manual's temperature range before powering on again.
  • For anything inside the deck, contact Segway after-sales or an authorized service provider.
