My 99 Deville's service stabilization system warning light

Customer Question

My 99 Deville's service stabilization system warning light has come on twice in past month. Not sure i understand what it means or what is does, since light goes off and everything seems normal now.
JA: Just to clarify, what are the exact lights you're talking about?
Customer: the system information section
JA: Are you fixing your DeVille yourself? What have you tried so far?
Customer: I haven't tried anything yet. I'm elderly, disabled and don't even drive the car much anymore.
JA: Anything else you want the mechanic to know before I connect you?
Customer: no I dont think so

Is an icp, pcm, mmm code what I'm looking for?
Expert:  Dan replied 9 months ago.

Select check all codes but RSM would be what we are mainly looking for.

Customer: replied 9 months ago.
There were others that came up but all had "no" except PCM had 2 on it. Now says PCM? RCM had no codes shown
Expert:  Dan replied 9 months ago.

Next time warning comes on check codes and let me know what they are, code is probably out of memory by now.

Customer: replied 9 months ago.
Its only happened twice in a month and I don't drive car more than 40-50 miles per month if that. If it comes on again I'll worry about it then. Thank you for your time.

Sounds good, I'll talk to you then. Have a good evening.
