service stability system...
I have a 2007 chev uplander LT and we replaced the ABS module and the PCM module and the Right rear speed sensor and we are getting this service stability system message on the dash....we have scanned everything..and this message will not go away...we have the appropriate scanners as well...what is the problem?

Are you sure you have the appropriate scanners? Generally need a Tech II scanner, or something else that will read body and ABS codes. What are you scanning with?

Maybe just do a quick basic procedure, disconnect the wheel sensor connection at each hub, put a little dielectric grease on the connection, and reattach. If you are looking at a intermittent problem and already replaced the PCM and the ABS module, may as well consider the course of action of the common issue of a intermittent contact at the connector.

Disconnect the electrical connector at each WSS and check the resistance across the terminals for the wires going to each WSS.
Do a continuity check for each wire from each WSS going back to the EBCM.
Keep in mind the SSS message can be initiated by more than just the ABS system and the WSS'*. I'm not sure on the Uplander, but on my Bonneville a bad steering wheel position sensor and a bad yaw sensor could both trigger the SSS light. The most common failures are a bad WSS, and lack of continuity to the WSS from the EBCM, which is why I suggest the first two steps.

I will try the dielectric grease...
there is no intermittent contact though because there are no codes coming up. Everything scans fine with no codes. In my opinion, when a issue comes up on the dash, and the vehicle is scanned, a code should come up, frustration when it doesn't and all parts have been replaced.
