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.

What he’s referring to is instructions Arnott now provides instructing owners to splice into 4 wires on the OBD harness and secure them with a T-tap connector.

Arnott, this is going to come back and bite you guys.

For anyone else in this situation, I binned the Arnott module and soldered a 25w 3.9ohm resistor on each of the suspension strut connectors.

Not sure why arnott wouldn’t take this simple and effective approach too as it works.

Monitor the area modified for excessive heat in such a critical area. It’s a big ask to have that measly wiring doing the work for a 25w resistor.
