I would think if the alarm is in valet mode, no sensors would trip the alarm. The alarm goes off even if the doors are unlocked, and locked in valet mode. I looked all over the hood, and didn't find a hood sensor. I'll look again this weekend. The hatch in back turns on a light when opened. I suspect that the alarm is tied into that, same as the front doors. If the speaker is disconnected, there should be little battery drain even if the alarm goes off --just the timer circuit. The OEM/ODM for the system is Code Alarm, now owned by Audiovox.

No chirps, so no sensors set it off. I suspect a weak solenoid that gets triggered by vibration. A replacement module will be tough to find/ I cut the wire to the alarm speaker.

The alarm will go off occasionally when not set on. Vibrations sometimes will do it --like on a ferry. Other times its sitting in my driveway at night. I replaced my car battery, as it was getting old --that didn't help. Any ideas? I'd prefer to fix myself. At minimum, I want the keyless remote to keep working. It would be nice to get the alarm reliable again, but I'd settle for disabling just the alarm system or the sound. I did find some data in my glove box.

Next time it goes off, I'll see how many chirps so I can check what set it off. 1998 Subaru Legacy Outback Wagon Left it in valet mode last night. Alarm went off two or three times during the night. I'll see how easy it is to just disconnect the siren until I can fix the system.
