Hmmm.....11 year old car.
The module is under the carpet under the driver seat. The easiest way is to remove the rear bolts and get access to the module.
Uhhh.....you can check the codes...and maybe do some light debugging. But besides that...if the car is riding ok. I would pass on throwing any money into it.
The current fix for the '93 Deville with a SSS lamp that is driving ok. IS either remove the bulb or cut the wire to the bulb.
Its a Cadillac...but its maybe worth $3000-4000 tops...its not worth new struts to fix this.
