The idle should relearn by itself within a minute or so if there are no other problems. Was the battery changed/disconnected? Why do you think you need an idle relearn?

How to removed and install The ECM

Your better off taking it to the dealer , after replacing it needs to be programmed or it will not run . Information from the old has to be up loaded to GM Tech 2 scan tool to load on new one ! Then you would need to pay for a subscription to GM'S service programming system to get software to program new ECM .
Program the ECM. Refer to Service Programming System (SPS) in Programming. If you encounter an ECM programming error, with a display message of "Starting Disabled, Remove Key" on the driver information center, with a diagnostic test code (DTC) of P1631, perform the "10-Minute Relearn Procedure" found in Programming Theft Deterrent System Components.

Where is the idle control sensor for 2004 Cts Cadillac

There is none.Idle is controlled by your computer. If you have problems, check these. Vacuum lines behind throttle body. You may have to replace your air flow sensor. You can also try this:
Engine cold.
Turn your key to on position for a full minute. Don't start the car.
Turn key off for 10 seconds
Turn key on for 10 seconds. (Don't start)
Turn key off for 10 seconds. Then start the car. Might work but in all probability your main airflow sensor (MAP) is the problem.

Replace the fuel filter. Hope the fuel pump isn't on the way out, cause it is expensive.

What does if mean when battery saver is activated on 2004 Cadillac cts

Generally it means you are drawing more power than the alternator is putting out, or if the engine is off the stereo or some other accessory is drawing power. The battery saver is warning you that you have just enough power left to start the engine. Could also mean you have a bad battery connection or your alternator is not putting out over 13 volts. If the engine is idling with air conditioning and stereo on for any length of time it could also trigger this warning as the alternator at idle speed may be unable to keep the battery at full.
