4) Bleeding ABS with Tech 2

I have a tech 2 clone but I have a ’96 and it only has the 3 sensor 4wal. On this there is no countdown or cycling of the ignition, as long as it is on with engine off, after the warnings it establishes communication and then says depress the pedal and it cycles the ABS about 4 times.

BTW this is a good resource for Tech2 paths. It’s all paths though even more than available for your truck but you could probably reduce this down if needed.

Also, if I can get to that screen just scrolling through function sitting at my desk then that means no communication is occurring to this point. So i would go and use the function to pull the VIN or something just to make sure you do have communication from the unit and through the DLC connector to the truck.
