Flight Crew Rejected Takeoff; General Maintenance Action
Aircraft
During our takeoff roll at approximately 80-90 KTS we received the Aural CAWS Alert along with the Red Level 3 (FLAPS) indication on the EAD. I aborted the takeoff and then returned to the gate. The tug driver witnessed our slats-extended and flaps 5 setting just prior to taxiing out to the runway. Contract Maintenance also verified with much troubleshooting upon our gate return that upon extending our slats and flaps 5--this is exactly what correctly occurred outside and it's exactly what we saw on both of our PFD's (flaps 5)--which is exactly what we had programmed into both of our FMS/MCDU's (flaps 5 for takeoff). For the takeoff roll our EAD showed a hollow green box--however; Maintenance Control verified that either the flap transmitter indication was improperly indicating a different flap setting than everything else; [which] equals a flap split indication.
B717 Captain experiences a takeoff warning for flaps at 80-90 KTS and rejects. The flap setting appears to be correct and the flight returns to the gate for maintenance.
