I noticed this morning that the headlights and tail lights no longer flash when I arm the alarm (factory unit).

I remember that you can program the alarm by removing the mallpgm fuse and listening for a sequence of chimes, which I did on my previous GTP.

I didn't do anything like that, it seems spontaneous, could it be that I hit buttons on the remote accidentally like a butt dial kind of thing?

It's odd and out of the blue, TIA for any help
