So... got ahead of myself and went down and fooled with the truck for a few minutes:

(1) turn ignition to ACC
(2) loud, continuous alarm + all traction, ABS lights comes on immediately
(3) tap the ABS motor (?) a few times with pliers, motor comes on (loud, kinda buzzy sounding) and runs for about 60 seconds
(4) loud, continuous alarm stops
(5) brake pedal has some pressure back in it
(6) depress brake pedal twice, motor comes on for about 3-5 seconds, repeat as often as you like

So, leaning towards burnt out motor, although I've heard some say that the accumulator can lead to a burnt out motor, so I might need to do both.

am getting a little confused about the exact or product number for the brake booster motor, could you confirm the correct part number for the motor or compatibile motors as well.

see the part nos of the motor according to toyodiy website : 47960-60090
hwever these other part numbers pop up while searching, and they appear similar as well

47960 -60010
47960-30030
47210-60110
