Aircraft
Taxiing to the active Runway 21 in ABQ; we accomplished the throttle burst and Before Takeoff Checklist before taking the runway. We set takeoff power and began the takeoff roll; the 80 knot call was made and all indications were normal as we proceeded with the takeoff. Reaching 108 knots the Takeoff Warning horn sounded and the Takeoff Configuration Warning light illuminated on the forward panel. A reject was initiated at 110 knots. As we were coming to a stop abeam F1; I cleared the runway at F1 intersection and stopped. Tower was notified during the reject and a passenger announcement was made after the aircraft came to a stop. Brake cooling information was loaded into the OPC and it was determined that we had a 75 minute wait period; 30 minutes of which had to be away from the gate area. An inspection of the fuse plugs was also required by a mechanic. We contacted Ground with this information; and they had us hold on Taxiway J between E and C taxiways for our 30 minute wait period. Passengers were informed of our time and we proceeded to Taxiway J.Company was notified of our situation; and we requested a gate be available once our 30 minute period was complete. Dispatch and Maintenance Control were contacted at this point to coordinate Contract Maintenance. Once at the gate; a Contract Mechanic arrived to inspect the brakes. Since we had an additional 45 minutes of brake cooling to comply with; I asked Maintenance Control if they could have the Mechanic try to determine the cause of the warning. There was no prior history on this aircraft. Required logbook entries were made with the pertinent information; and since the brake energy was over 18.5 million FT/LBS; a logbook entry was made for that too. The trim setting was 4.7; flaps 1; speedbrake handle was down. After the systems check and tire inspections were complete; and logbook signed; we continued with no further issues.I felt there was resistance from Maintenance Control to have Contract Maintenance perform a check to determine cause. Granted; an 'Info Only' entry could have been sufficient; but to have the warning come on at that speed; I felt it needed to be addressed further.
B737 Captain reported a rejected takeoff in ABQ at 110 KTS in response to a takeoff configuration warning light for an unknown reason.
