Ride control problem

[KRJ]

Hi everyone , I want to start to thank you for all the info on the site and forum that has helped me a lot in fixing problems with my Z

I now have a problem with the ride control system that I can not figure out. I had no previous problems with the system and it was working perfectly until one day the "service ride control" light came on and when I pulled the codes I got all the codes that where listed in the service manual Now I don’t believe that all these problems could come up at the same time so I am thinking that maybe this could be a loose connection or the SRC Module.

Any advice on this is greatly appreciated so I can bring this beast back to tip top condition.
