ok, i've been doing some research.. since my tech-1 by itself can't communicate with my ABS in my '94 s10 blazer.. apparently, I need some additional hardware as the ABS uses OBD-II communication protocols.. (I want to call it Class-2? but I might be wrong there) either way.. I need additional hardware.. and I really could use being able to work on the ABS system.. I disconnected the wrong line and believe I got air in the ABS motor.. i've bled and bled the brakes and they still soft.. i need to get access to the computer to make it cycle and bleed the air out.. I've heard tell of ways to do it w/o the scan tool.. but I don't understand that process.. something about attaching a tool to the motor to open the valves?

so back to my original question... does anyone have this additional hardware they'd be willing to part with?

 

ok.. I've just ordered another piece of the puzzle...

just bought this..
