Look on your fuse box and there should be one called ECU. On my Civic is just E.... My one is on the top left hand....

Check your alarm back up battery that might need replacing....

Because your battery is flat the alarm has no power and is going off, it seems your siren backup battery is flat too so that's the only reason it's not screaming. Get a new battery and everything should be fine
