How to troubleshoot Dormakaba Quantum II RFID ECU Rfid Systems reader with no LEDs?
- K
  Kristen DoyleAug 3, 2025
  If the Dormakaba Rfid Systems reader has no LEDs lit, it could be due to several reasons. First, check the reader ribbon and power lead connections to ensure they are properly seated and plugged in. Next, verify that there is power at the two white power leads and that the green power pilot LED is on. Also, inspect the fuse. If none of these steps work, the reader or ECU PCB might be faulty and need replacement.
