Wow, Electronic Counter Measures built into a 1990 Buick. That's way better than a FuzzBuster.

Sorry I couldn't resist. I know nothing about the re-learn procedure of what I presume is the Electronics Control Module.

Disconnect the battery completely; remove all cables, for at least eight hours to defeat the ECM's internal battery wait another four hours then reconnect. The prompts will automatically reset.

Are you referring to a relearn after the battery has been unhooked? About the only thing that needs to be relearned on a vehicle of this age is the idle strategy. Just start the engine, let it idle for a few minutes, then drive it. If you have any idle or drivability issues after that, those issues need to be properly analyzed

Welcome to the insanity. 3 & 4 have spelled it out pretty well. Good luck.
