## Discrepancy

DURING TAXI, AN ICE DETECTOR FAIL WARNING MESSAGE WAS NOTED BY THE CREW.  THE ICE DETECTOR WAS PREVIOUSLY DEFERRED, AND THE WARNING LIGHT SHOULD NOT ILLUMINATE.  THE AIRCRAFT RETURNED TO THE GATE.  MAINTENANCE INSPECTED AND DETERMINED THAT THE DETECTOR WAS FAULTED IN A WAY THAT CAUSED THE WARNING LIGHT TO ILLUMIMATE.  MAINTENANCE REMOVED AND REPLACED THE ICE DETECTOR IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 30-51-00.  OPERATION CHECKS WERE SATISFACTORY AND THE DEFERRAL WAS REMOVED.
