Hello and welcome to JustAnswer!

It's possible that the problem could be the module that controls the system but it's not that likely.

The warning is coming on because the module has seen a failure in the system and set a fault code. The first step in diagnosing the problem is to use a scan tool or code reader to see what fault codes are setting and then testing can be done from there based on what codes are set.

Do you know what fault codes are setting?

It is a b code that only dealers can view with a tech 2 scanner I am trying to avoid dealer does auto ride have a seperate module from suspension or is there just 1 module for real leveling and auto ride?

The problem doesn't necessarily have to be diagnosed by a dealer but a scan tool capable of communication with the suspension module is necessary. If you aren't able to see any visual problems with suspension components then a scan tool will be necessary to proceed with testing.
