Cadillac Repair: 93 deville service SSS, diagnostics test, mechanic

Question
my "service SSS" light came on. SSS stands for "speed sensitive suspension/steering".  my mechanic said he'd have to do a diagnostics test and i want to know if there is anything else i can do. there doesn't seem to be a problem when im driving, but i don't know how big of a problem it is. i just want to know how i can fix this. thank you.

Answer
Lets see what codes your computers have:

1. Ignition ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER buttons until the whole display illuminates and release the buttons.

3. CODES will start to appear and will stop. Write down ALL the codes in the EXACT order in which they display and let me know what they are.

5. Turn ignition OFF.
