Shocks Inoperative

Looking for advise.
I have a 2003 50th Anniversary Convertible. The shocks are inoperable. The first place I took the car discovered that I had a bent rim. I replaced the rim but that did not solve the problem. The second place I took the car for repair cleaned a ground cable and checked the PCM module for loose or corroded connections. They thought they fixed the problem, but on the way home the messages and poor handling came back. The codes that came up from the short trip home were:

PCM - Powertrain Control Module
P1652 Powertrain Induced Chassis Pitch Output Circuit

SDM - ?
U1096 Loss of Communications with IPC - Instrument Panel Cluster

IPC - Instrument Panel Cluster
U1056 Loss of Communications with RTD - Real Time Damping

RFA - Remote Function Actuation
U1096 Loss of Communications with IPC - Instrument Panel Cluster

Any thoughts?

I don't have my service manual handy, but I believe everything listed goes through the BCM.

Could I remove the BCM from my 2004 and try it in the 2003? The 2004 does not have the Ride control option.

I wouldn't swap the bcm Did you hit something is there another bent part? I'd get it in the air and see what is going on underneath.

If you hit something hard enough to bend a wheel, the first thing I would check is the shock sensor, linkage and harness on that corner. The sensor is plastic and could be cracked and its not repairable. I seem to remember a post about one being replaced and it ran @ $100. I bought the whole F55 set-up from a C6 for parts just in case something like this happened to my Anny. The F55 has its own control module in the left rear trunk compartment and there are a lot of connectors to check before replacing $$$ parts. Good luck !

Today I checked the wiring on the MRC Module in the trunk, wiggled all the connectors. Then raised the car one side at a time and wiggled all the connections on the shocks and wheel sensors. Then I cleared all the codes and took it for a test drive. It's working!! Thanks for the Help!!
