Have an 01 caravan that has unwanted abs engagement....around 10 mph or so if you lightly apply brakes the abs kicks in....looking at wheel sensors on scanner they all read same mph and none drop out...no codes set...there is a reference voltage tha bounces from 4.1 to 9.9 volts

hi ngk has a good study on something like this it turned out to be high resistance in abs sensor circuit so module was acting up causing low rpm engagement

High 5 v reference usually is the result of a bad pcm ground and low 5 v reference , the result of bad pcm power.

hi sir because of the fluctuating voltage I am suspecting a bad ground at g100 or possible the g200 spot which is the traction control module the speed sensor have two wires which are powered and grounded thru brake control module im still trying to master this stuff so please forgive if I lead you down the wrong path but I guess as SD would say eliminate all the variables
