## Discrepancy

ECAM SMOKE LAV+CRG DEFAULT.  REPEAT WRITE-UP.  REPLACED FWD LDCC 1WH, TESTS GOOD.  LOG 2...CFDS SHOWS SAME FAULT AS PREV.  UNABLE TO TEST SYSTEM UNTIL RESET OF BOTH CHANNELS OF THE SDCU. THEN TEST OK.  AFTER THIS RESET FAULT RETURNED WITHIN 5 MINS.  REF MM TRBLSTG TASK 26-17-00-810-803.  REPLACED SMOKE DETECTOR 1WH IN FWD LDCC, TESTS GOOD.
