Hoping someone can help me.....

I am trying to read the ABS codes (light is on) on my 2003 GrandPrix GTP. I just purchased a innova 3160b scan tool and it will not read them. It was dicey whether it would read them in the 1st place (some people reported it would work even though the documentation says only 04 models and up) - so it is going to be returned.


I have seen some tool recommendations in another ABS thread but I am looking to find something that will definitely work with my 03 GTP.


Suggestions?
