Ok... I have a genuine GM Tech-1 and assorted modules for my '94 S10 blazer .. but I still can't talk to the ABS controller (4WAL)
from what I've read, apparently the abs controller uses OBD-2 bus topology? CanBus maybe? so I was hoping someone might explain exactly what hardware i need to communicate with it. I have air bubbles in my ABS motor from my own fault.. I'd really like to be able to actuate the controller while bleeding it..
