## Discrepancy

EICAS MESSAGE 'SPOILERS' DISPLAYED WITH FLAPS SET AT 25 OR 30.  CREW REPORTS "SPOILERS" EICAS MESSAGE DISPLAYED ON TAXI OUT AFTER SECOND ENGINE START, FLAPS AT 5, AT ARRIVAL.  UNABLE TO CLEAR EICAS MESSAGE & OVERHEAD LIGHT.  CYCLED CIRCUIT BREAKERS & DEPOWERED ACFT, NO HELP.   ALL SCMS BITE CHECKED GOOD BUT UNABLE TO DETERMINE CAUSE.  WIGGLED ALL SCMS & NOTED 1L MODULAR WOULD CAUSE FAULTS AS DESCRIBED.  REPLACED IAW MM & ALL CHECKED GOOD. MESSAGE CLEARED & OPERATIONS OK.
