Question about 2001 GMC Yukon
Brake pulsation is caused by warped brake rotors, not sure the ABS light and the pulsation are related, The ABS warning light requires a scanner to be connected and to read the fault code that is stored when the ABS warning light is turned on.

SOURCE: anti lock brake system
If the light is not on it may not be the ABS that is pulsating on slow braking but it may be that your have warped brake rotors, even if the rotors were replaced with the pads the new ones may be warped already, we always check new rotors on a brake lathe before installing them because we have seen this happen many times

SOURCE: ABS light stays on
that has four wheel anti lock so your gonna need to either take all them off and clean ends it may correct the problem but more than likely your gonna have to take to a large shop that has abs computer to find which sensor is bad then correct the problem

If the new rotors were not allow to seat after replacement they will warp extremely easily. Easy to check. Remove wheel and check for trueness of rotor, a dead give away is if you see a blueish tint on the rotor.

try unbolting the front abs sensors and cleaning rust off from where they bolt to.these vehicles build up rust under the sensor and create a bigger gap
