there's nothing to 'read' data-stream-wise on the fx3 shocks. Even the factory scanner just ground the appropriate pin for the shock controller which will spit out the codes via the flashing light in the dash. There are only a handful of codes for the shock controller anyhow. It is useful to find out which corner you have the problem on more than anything else.

you can just do the paperclip shorting method for now without having to buy anything. I forget which terminal, but it should be well documented online somewhere (or if you have the FSM).
