My cars 'siren' (theft/panic alarm) would sometimes go off on its own. I found a fuse that was labeled ECU, which in the manual said it is the 'siren, PCM' (10A). I pulled it, and the siren is dead now.
I drove it for awhile and all seems well. The only thing I'm thinking is the PCM part of the labeling. Is this something to be concerned about?
