      I read this on another forum,

      harness D6095500(IPU to CIS) was partially unplugged from the CIS.

      Good luck, sounds like a tough one.

          Ok, when you replaced the controller, did you also swap the nvram on the controller and the eprom on the BCU? Failure to do these things will give you that sc code.
