## Discrepancy

APPROXIMATELY 30 MINUTES AFTER TAKEOFF, CREW RECEIVED INTERMITTENT ECAM WARNINGS FOR CARGO SMOKE, FORWARD AND AFT COMPARTMENTS.  NO ASSOCIATED ODORS OR SENSOR WARNINGS.  CREW ELECTED TO DO A PRECAUTIONARY LANDING AND DIVERTED TO ABQ BUT DECLARED AN EMERGENCY FOR LANDING.  AIRCRAFT ARRIVED WITH MAINTENANCE STATUS MESSAGES FOR CIDS 1 AND SMOKE.  UNABLE TO CLEAR CIDS 1 SO UNIT WAS REMOVED AND REPLACED.  ALSO REPLACED OBRM AND RANG WIRES FOR CONTINUITY AND GROUND BETWEEN CIDS 1 & 2 WITH NO FAULTS FOUND.
