I have the EDC Electronic Damping Control malfunction message so I read the codes and it is pointing to the "satellite" that controls and is mounted to the rear left shock. Does anyone know if you can change this without changing the shock?

I have an appointment at the dealer on Wednesday and I just want to know what I'm talking about before I get there and they try and bullshit me.

My Google and forum research is not paying off on this one.
