Arnott Suspension bypass module not working - CEL U0122

[Jimxms]

I just removed my Z55 suspension and replaced it with an Arnott/Bilstien kit (C-3184). This came with a bypass module that taps into the OBD2 port. I've wired it all correctly and removed fuse #2 from the engine fuse box (as required in the Arnott manual), but I'm getting code U0122 popping up all the time "lost communication with the vehicle dynamics control module". Has anyone else had this happen? I'm tempted to just try using resistors instead.
