you need to use a scanner to clear the codes, go to pep boys or auto zone, they will do it for you usually free of charge but if after they are cleared by the scanner and still come up you may have a serious engine or tranny problem. good luck

The security, antitheft or lock picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well. http://vatspasslockpasskeysecurityhelp.yolasite.com/

say again, what device.use the correct name, there are vast safety devices on all newer cars.is it in cab, under hood, where?

You have to have a shop plug in a computer and read the on board diagnostic code in your cars computer. On those caddys it is usualy suspension needs replacing, or worn brakes. Most shops will do it for free. Or you could try unhooking your battery for 5 min to clear the code and hope it stays off.

I would see if you can find an electrical diagram for the vehicle. Maybe online or for example my library has a ton of repair manuals. It may be that the ground connection is broken on that side, if that is an option. If you haven't switched out the bulbs from side to side I would do that as well. Sometimes bulbs can look ok but still have an internal fault.

You may need a repair shop. Code 440 means the computer has found a leak in the venting system for the gas tank. The problem could be the gas cap, a rubber hose, or a valve between the tank and the vapor canister.

Drivers door switches likely bad.

Need more info. does it crank?

just try to make sure the earth strap is tight ,should still be good but if faulty THE FUEL PUMP IS LOCATED IN THE GAS TANK ACCESSIBLE VIA REMOVING THE BACK BENCH SEATCadillac Eldorado Fuel Pump - Free Shipping - Replacement, Delphi, Airtex

Those vehicles have a chip key. It has like a little chip in the key that the car picks up and will allow it to start. But if you dont have the key your not going to start it
