Check for vacuum leaks around the intake. This is the most common cause for these codes.

2003 Cadillac Deville stalls while driving

The engine on my 2003 Deville just shuts off while I'm driving. I just bought the car and This has already happened twice. I was driving about 30mph at the time. Could it be fuel related? I have been using regular gas. The manual says 87 octane is ok. What causes this?

Key Fob Auto Learn
This procedure will first erase all known key fobs. The procedure will then program a single or multiple key fobs. Method 3 is a series of three 10-minute key cycles, for a total of 30 minutes. This procedure requires that you have a replacement key fob and the vehicle mechanical key.

Important: All previously programmed key fobs will be erased upon completion of the 30-minute programming procedure. The order in which the key fobs are programmed will determine its numbering position within the RCDLR memory. The first key fob programmed will be key fob #1, and the second key fob programmed will be key fob #2. The number stamped on the key fob case is for reference only: #2 can be programmed as #1.
Do not place any known good key fobs in the vicinity of the vehicle when programming. 

The vehicle must be OFF. 
Place the replacement key fob in the console pocket with the buttons facing forward. 
Insert the vehicle key in the driver door lock cylinder located in the driver door handle and cycle the key 5 times within 5 seconds. 

The DIC will display a message: OFF/ACC TO LEARN. 
Press the OFF/ACC portion of the ignition button. 
The DIC will display a message: WAIT 10 MINUTES, then it will count down from 10 to 0, one minute at a time. 
When the counter reaches 0, DIC will display OFF/ACC TO LEARN. 
Repeat steps 5-7 two more times, for a total of 30 minutes. 
The DIC will display a message: OFF/ACC TO LEARN. 
Press the OFF/ACC portion of the ignition button. 
A beep will occur and the DIC will display: READY FOR FOB 1. At this time all previously known key fobs have been erased. When fob 1 is programmed a beep will be heard and the DIC will display a message: READY FOR FOB 2. 
Additional key fobs can be programmed by taking fob 1 out of the pocket and inserting fob 2. If desired, up to 4 fobs can be programmed. Once 4 fobs have been learned, the DIC will display a message: MAX FOBS LEARNED, and automatically exit the program mode. 
If learning less than 4 key fobs, press the OFF/ACC portion of the ignition button to exit the program mode. 
Operate the active portion of each key fob in order to finalize the programming sequence and verify correct system operation. 

Good luck and hope this help's keep me posted, there are 3 other methods and the 5th method is a tech 2 scan tool that the dealer uses but this should work on your year of cadillac.

Hi, there are two fuse box locations. There is one under the hood and there is also one under the back seat next to the battery on the driver side. To get at the one under the back seat, grab under the front of the seat bottom and give a tug upward. Be careful though, the plug for the rear seat heat is attached to the seat bottom on the passenger side and the wires aren't very long.

I'm guessing you are talking about the cover or fascia and not the enforcement part of the bumper assembly. Below are the instructions for removing the fascia. Also in some other pictures and instructions are for the air deflector which is only the bottom part as well as the extention which basically snaps in but be careful removing it not to mess up the clips. These were the largest pictures I could post on here due to a size limit when posting. If you need larger pictures or you were talking about the entire bumper assembly, feel free to email me at [email protected] with your vehicle information and detailed questions so I'm sure to send the correct stuff to you. No charge or cost to you for it, don't mind helping. Hope this is what you are looking for and hope it helps.....
