726-41-02 not there

I changed my battery recently and as a result, several things quit working. Remote start, Lock flash confirmation, etc. I looked at the list in BCM, and I don't see the code. The list I have has 726-41-02 as the code for that and it's not there. Now what do I do? I reset the batter monitoring system, but that didn't do anything.

Thanks,
Steve

Don’t hate me, this might sound trivial….have you tried disconnecting the battery and draining the capacitors by jumping the positive and negative leads for a few minutes or leaving it disconnected overnight?

I know…I know….the old “well did you restart your computer?”….but I gotta ask.

I don't hate you... It's a good suggestion that is often overlooked. Unfortunately, I already tried that. It didn't work. I've used various AI models looking for suggestions and they all say that this model year had the settings for flash on lock in various places, not the standard ones. I've tried all suggested, but none work. I'm beginning to think it's a problem with the module itself.
