CRJ200 Captain receives two status messages during taxi out indicating 'IB GRD Spoilers Fault' and Flt Spoilers Fault.' The crew determines that the aircraft is good to go without maintenance action. During takeoff the configuration warning sounds and the crew rejects.

Narrative

On taxi out; the flight crew noticed that we had two status messages; indicating 'IB GRD Spoilers Fault' and 'Flt Spoilers Fault.' The First Officer reviewed the QRH; which said that all systems were operating normally. Per the company's operating manual; the flight could be continued without communicating with the Dispatcher if it is determined that the flight could be operated safely in accordance with the provisions of the MEL. We determined that the flight could be operated safely in this manner; so we continued with the takeoff. We also were receiving the green 'Takeoff Config OK' advisory message; further confirming the safety of the takeoff. At about 40-50 KTS on the takeoff roll; we received an EICAS warning message and aural warning of 'Config Spoilers.' We discontinued the takeoff safely; and taxied off the runway. We returned to the gate; received corrective maintenance; and continued the flight without incident. The undesired state was that the airplane's configuration warning system alerted the crew to a possible unsafe situation during takeoff. After this experience; I will treat all spoiler-related status messages as a threat to an incident-free takeoff. In this case; I would consult with my Dispatcher and Maintenance Control to address the status messages before attempting a takeoff.
