## Discrepancy

CREW REPORTED THAT ON APPROACH INTO ORD, RECEIVED A LAV SMOKE INDICATION ON EICAS.  THE FLIGHT ATTENDANT CHECKED THE LAVATORY AND FOUND NO SIGNS OF SMOKE OR ODOR.  THE QRH WAS FOLLOWED AND THE CIRCUIT BREAKER WAS PULLED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE LAVATORY SMOKE DETECTOR.
