u need a new altenater

To check the shocks bounce the truck 3 times and let it go. It should rise past level and come back to level and stop. If it doesn't then the shock on that wheel is bad. Don't be shy when you bounce it, I use my knee on the bumper and drive it down. Do each wheel.
When you have that done, jack up 1 front wheel. Spin it and watch the tread near the ground. It should spin freely with no wobble. If it wobbles sideways at one spot you likely have a broken belt in the tire. Check both front ones for sure. After that grab the wheel top and bottom and move it in and out. There should be no movement. If there is you have a bad ball joint or possibly a wheel bearing. You'll need someone to watch to see what moves to tell the difference. Then grab the wheel at 3 o'clock and 9 o'clock and try to move it in and out. Again there should be no movement, unless the steering wheel turns. If the wheel moves and not the steering wheel, you have bad tie rod ends that need replacing. Then do the other front wheel.
It's also possible that you need a front end alignment. If you have to replace ball joints or tie rod ends, then get it aligned after you repair it.
Hope this helps.

You will need to have the ignition barrel removed and replaced with a new one.

The car is telling you there's a problem. The light isn't there to bug you or anything. It shows that something is wrong and it needs to be fixed. Fix the problem and it will go away. What a concept!

• Well first thing is you have OnStar on that Escalade and if you push the button they can tell you the code right away right there at anytime.

• Here is a list of technical service bulletins for your vehicle.http://www.obd-codes.com/tsb/2002/cadillac/escalade_ext/

• OK so OBDII codes are generic among all vehicle manufacturers. Go to this link http://www.obd-codes.com/trouble_codes/ and scroll down a bit and the codes will appear. This is where your Escalade codes will be as well. These are codes that begin with P0.

• If you have got your vehicle scanned with an actual scanner (not just an OBD II reader) then and you have GM specific error codes then you go here http://myweb.accessus.net/~090/dtcobd2m.html#gmd and scroll down a bit. These are the "DTC" codes as well some others. They are GM specific. There won't be code for just a 2002 Cadillac Escalade.
• Again if the codes begin with P0xxx then they are generic for most vehicles. If GM (Cadillac) specific then the second site is where you should look.

Hope this helps and thank you for using FixYa.

Hello: You need to use a High Tech type scanner or GM Tech 2 to match the radio to the truck with the vehicle VIN number. There is NOT a code.
