i am sorry for the long wait

if you do NOT have a scan tool take the truck outside and carefully drive it slow on gravel or dirt and get the ABS to activate

do that a few times then manually bleed it again it might take a few times of doing this but that should get the trapped out of the ABS into the lines to manually bleed out any air still trapped in the ABS unit

can i power the abs motor with 12 volts for a couple seconds will that do the same thing
Chevy Mechanic: Gary, Chevy Technician replied 1 year ago

you can but that will only run the pump you need the pump to run and the internal valve to move to push out any air without a scan tool and by activating the ABS slow when driving will run the pump and cycle the internal valves
