Just wanted to send sometjhing back to the forum for helping me out in my jams with the car.

FYI, for later model Caddy's If you have ONSTAR they will scan for codes while you wait. The initial response is limited but if you request added information they will transfer you to a specialist who will give you current code reference number as well as any retained error codes with their meaning.

My most grateful thanks to the original contributor of this info. I've just used this method to access my 2001 Deville's codes and, although the actual read-outs meant nothing to me, after a couple of attempts, I was able to extinguish a "Service Engine Soon" light that had refused to stay off - even after my local independent mechanic had replaced the apparently faulty Evac Purge Valve (in the emissions system) that his hand-held diagnostic tool suggested was the cause of the light coming on in the first place.

Before accessing the codes myself, I'd previously been told by two separate service managers - one at a Pontiac/Buick etc. dealership and another one at a dedicated Cadillac dealership - that in order to sort this service light thing out, I'd need to have the car connected to their super-duper diagnostic computer, the immediate cost of which (without any actual work being done on the car) being a simply outrageous $130. Naturally, I declined the offer and I can tell you I got a huge kick when I'd finished seeing that infernal service light finally go out - and stay out! It's communities like this that make the internet so great.

While we're on the subject of codes, however, does anyone know of a reference source that explains what all those arcane codes the car throws out actually mean?
