97 GMC truck ABS module

I have a 1997 GMC Truck that im pretty sure at this point has gotten air in the abs and  was curious to what is exactly needed to bleed the abs module

a high dollar scan tool can do it , or if you look there is a bleeder on abs module, its takes a while to get all the air out , and after you do you need to bleed all the brakes again

It needs some pressure to even activate the ABS. Gravity bleed then pressure bleed then redneck bleed. AKA go on some dirt or gravel at 20 mph and slam the brake pedal. Do this 3 times. This will bleed the ABS motor, then pressure bleed again. Autel makes nice scanners that have an auto ABS bleed application which is incredible. Just used it yesterday on my 02 z71 all you do is hold the brake pedal and the scanner pulsates the motor a few times. Peace be the journey!
