## Discrepancy

(CAN) A "LANDING GEAR NO DISPATCH" MESSAGE WAS DISPLAYED.  IT HAD OCCURRED EARLIER THAT DAY BUT WAS RESETTABLE IAW THE FIM 32-00-00-810-801-A.  ANOTHER RESET WAS ATTEMPTED BUT THE CONDITION RETURNED SHORTLY AFTER PUSHBACK.  TROUBLESHOOTING REVEALED A WIRE BROKEN ON THE LT MLG DOWNLOCK SENSOR HARNESS. THIS HARNESS WAS REPLACED IAW AMM 32-00-01-000-801-A AND CHECK SERVICEABLE VIA THE PROXIMITY SENSOR ELECTRONICS MODULE, PSEM. THE ACFT WAS FERRIED AND GEAR SWINGS CARRIED OUT FOR PRECAUTIONARY REASONS.  CHECKED SERVICEABLE AND ACFT WAS RETURNED TO SERVICE.
