Re: engine code access
Yes, or go to autozone and let them read the codes for you for free (other parts stores may do for free also).
Your's is an OBD 1 (not OBD II) I think, check with the parts store for sure, should be < $40 or so for a simple model.

Get a code reader hook it up and pull the fault codes up and see what is shutting it down. If you don't have access to a reader most parts stores will use there readers to pull codes for you and help you figure out what the problem is and sell you the parts. Auto Zone is good about this and don't charge you to pull the codes up.
You'll need someone to check the body computer for trouble codes to know what to do next. You may find an auto parts store with the right code reader to access the body computer, but most readers only access the engine computer.
Once you have the codes a mechanic can check those codes to find the problem.
you need a code reader plugged into the port, often under the dash, some shops will read the code for free or charge a small amount to be credited toward repair, You can buy a reader from about $75 and up at an auto parts store or onine, you may need computer access depending on device
To begin with, MANY codes cannot be accessed with a generic code reader. The code readers can only access the continuous memory codes. They cannot read manufacturer specific or one trip codes. So just because yoiur generic code reader is not reading any codes, this DOES NOT mean that there are no codes to be read. If the light is on, there are codes. Period! (unless there is a control module fault that must be corrected).
If you want to find out what is going on with your vehicle, the FIRST thing you need to do is to STOP CLEARING THE LIGHT! You are not only turning the light off, but you are also erasing important data that will be needed to properly diagnose the problem.
Get it checked by a trained technician with the proper equipment to access the engine data.
If you had the car scanned with a generic OBDII code reader (Which is what they use at all the parts stores) this is probably why it is not showing any codes. You have "Vehicle Specific" codes. This means that the problem with your Check Engine light is not a problem that will generate a "generic" OBD code. A generic OBD code reader will not read codes from your Antilock Brake System or your Traction Control System at all... You need to have it scanned professionally by someone who has the proper equipment and software to access the Controller Area Network (CAN) in your vehicle.
Unfortunately not. This vehicle has a very sophisticated CPU and the old age tricks will not work on this particular design. You will need to gain access and allow a professional GM tech to pull the Cadillac codes. An ordinary code reader may miss the exclusive Cadillac codes that may be stored at any given time.
A certified GM/Cadillac code reader will be your best bet..
