"some" ABS systems say to NOT use dot 5 fluid because it does something to the accumulator in those systems. at least up until the 2002 MY, dot 3 was the only fluid to use in minivan ABS systems according to the FSM.
besides, DoT 5 is tOo ExPeNsIvE for the ol' DoC....................... TiTeWaD that he is............
From what I understand DOT5 will foam and when the ABS pump runs, it will foam up and fail as if there was air in the system.
