I cannot perform an auto bleed to my 1998 gm k1500 has anyone had issues with this?  on another note I ordered a maxi check pro . but it does not state that when the screen comes on the maxi check . I know these things are all the same just have different programs. any one else have a maxi check pro if so does it say pro anywhere on it or on the start up screen mine does not and it does not seem to do anything that the description tells me it is supposed to.
