HEllo I am new to this board and to my car as well. It is a 1995 Z28 6spd. In the dash the ABS INOP light is on. Now when I hook my scanner up to it says there is a communination error. I have tried a Snap-on micro scan and a larger snap-on model that is supposed to read OBDll and OBDl. It has the OBDll style connector. So are there any ideas on what the problem is?

Also I dont know if this would even tell be why the ABS inop light is on anyway.

Any help is greatly appreciated, thanks, will
