1990 C4 Module 7 err

Good morning,
I recently purchased a 1990 C4 that needs a bunch of work. I have been looking on line for an error code that I pulled up on my digital dash that reads (7 err) and I cant find anything on line about module 7, nor am able to clear it. Any ideas?

Thanks

SAL

What issues do you see when driving? any other codes or indications of something causing issues?

I doubt Sal will respond but I believe the Module 7 'Err' should be of no concern. I believe that Module 7 was intentioned for 'Active Suspension' builds and there were none so documentation in the FSM etc. isn't there. I believe I've seen this mentioned other places also. Now I believe that maybe '96 if it had F45 (Real Time Dampening) would have information in Module 7.
