Narrative:

During the takeoff roll; at about 20 KTS; a bleed 2 valve failure EICAS message appeared on the EICAS. We aborted the takeoff and while clearing the runway; the message disappeared on its own without any crew action. After coming to a stop; we ran the QRH and after landing checklists. I then called dispatch and maintenance control and; after discussing the situation with them; dispatch and I agreed; with the concurrence of maintenance control; that another takeoff attempt was reasonable. We then ran the after start; taxi; and lineup checklists again. We initiated a second takeoff attempt and the same message reappeared at the same time as it had on the previous attempt. We again aborted and after clearing the runway; returned to the gate. The message also disappeared again without any crew action. Callback conversation with reporter revealed the following information: this airplane had a history and several components were replaced. A logic card was replaced and a high stage engine bleed valve was replaced previously. Reporter had no idea what the actual fix was.

Narrative: DURING THE TKOF ROLL; AT ABOUT 20 KTS; A BLEED 2 VALVE FAILURE EICAS MESSAGE APPEARED ON THE EICAS. WE ABORTED THE TKOF AND WHILE CLEARING THE RWY; THE MESSAGE DISAPPEARED ON ITS OWN WITHOUT ANY CREW ACTION. AFTER COMING TO A STOP; WE RAN THE QRH AND AFTER LNDG CHKLISTS. I THEN CALLED DISPATCH AND MAINT CTL AND; AFTER DISCUSSING THE SIT WITH THEM; DISPATCH AND I AGREED; WITH THE CONCURRENCE OF MAINT CTL; THAT ANOTHER TKOF ATTEMPT WAS REASONABLE. WE THEN RAN THE AFTER START; TAXI; AND LINEUP CHKLISTS AGAIN. WE INITIATED A SECOND TKOF ATTEMPT AND THE SAME MESSAGE REAPPEARED AT THE SAME TIME AS IT HAD ON THE PREVIOUS ATTEMPT. WE AGAIN ABORTED AND AFTER CLRING THE RWY; RETURNED TO THE GATE. THE MESSAGE ALSO DISAPPEARED AGAIN WITHOUT ANY CREW ACTION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THIS AIRPLANE HAD A HISTORY AND SEVERAL COMPONENTS WERE REPLACED. A LOGIC CARD WAS REPLACED AND A HIGH STAGE ENG BLEED VALVE WAS REPLACED PREVIOUSLY. RPTR HAD NO IDEA WHAT THE ACTUAL FIX WAS.
