What Error 410 Means

Error 410 on Bosch eBike systems indicates that the drive unit has detected a stuck, jammed, or continuously active button signal from the display or remote. The controller monitors button input continuously — if any button registers as permanently pressed for more than a few seconds, the system raises error 410 and disables motor assistance as a safety measure.

Affected displays: Intuvia, Purion, Purion 200/400, Kiox, Kiox 300/500, Nyon (all generations), Smart System Intuvia 100.

Common Causes

  1. Mud or debris under a button cap — Fine grit under the + or - button physically prevents it from returning to resting position after being pressed.
  2. Water ingress — Moisture after heavy rain or washing can cause the button membrane to swell or PCB contacts to bridge.
  3. Worn button membrane — On older displays, the rubber membrane can degrade and lose its spring-back property.
  4. Display cable connector fault — A partially unseated connector can cause signal noise the controller interprets as a stuck button.

Fix Procedure

Step 1: Power Cycle

Remove the battery for 30 seconds, reinstall and power on without touching any buttons. If error 410 does not immediately reappear, the fault was a transient glitch.

Step 2: Clean All Buttons

Using a soft-bristle brush dipped in isopropyl alcohol, scrub around every button gap on the display and remote. Follow with compressed air to clear loosened debris. Allow to dry fully before powering on.

Step 3: Reseat the Display Connector

Disconnect the display cable connector, inspect for corrosion or bent pins, and reconnect firmly. Restart the system.

Step 4: Test Each Button

Press each button individually and hold for one second. If error 410 triggers on a specific button, that button mechanism has failed.

Step 5: Replace the Display

If all buttons test clean and the error persists, the display PCB has an internal fault and must be replaced.
