[We] aborted takeoff between 40 and 50 KTS for a Bleed 2 Fail EICAS Message. First Officer called out the EICAS message; I aborted the takeoff and safely exited the runway. We pulled off onto the taxiway; ran the Aborted Takeoff Checklist; and then ran the Bleed 2 Fail Checklist. (I asked for the Bleed 2 Failure Checklist first but the First Officer politely asked if I wanted the aborted takeoff first: First Officer; thanks for the help) the message cleared and we prepared for takeoff again and upon resetting the aircraft for takeoff we got a Pack 1 Failure message. We ran the checklist; the message did not go away so we called Maintenance Control and after talking with them for several minutes the best course of action was to return to the gate and allow Maintenance to look at the aircraft. Upon inspection the mechanics decided the aircraft needed more work so we received an aircraft swap. Aborted takeoff; to be honest everything ran smoothly and like clock work. Thanks to the First Officer for catching my checklist call out; he pulled the Abort Takeoff Checklist as I set the parking brake and asked if I wanted to do it first before the Bleed 2 Failure Checklist. The night prior had been a very short overnight with an almost 2 hour delay at 5:00 am in the morning due to the Flight Attendant showing up late and the First Officer never showing up for the flight at all. The flight was a totally different crew than the morning flight.
The crew of a EMB-145 responded to a 'Bleed 2 Fail' EICAS message by aborting the takeoff between 40 and 50 KTS and exiting the runway. The Captain called for the 'Bleed 2 Fail' checklist; the First Officer offered that the 'Aborted TakeOff' checklist was perhaps sequentially preferable; and the checklists were accomplished in the appropriate order.
