1991 Toyota MR2 Turbo.
This car has been in my garage since 2009 while getting work done to it on and off. The alarm worked before I parked it and while working on the car. Battery for the car has been disconnected for long periods of time between engine work. I had disconnected the alarm horn to reroute the wiring and when I connected it again and tried everything out I noticed this:
I can program remotes and I can arm and disarm the alarm like before. The problem is that when the alarm is not triggered the alarm horn is going off. When I trigger the alarm the horn stops. So the horn is working backwards.
Like I said I can program anything on the alarm but the horn is working backwards.
Do I need to do a reset on the alarm and how do I do that? I have the valet code and that works fine too.
Thanks.

Also I noticed that when I disconnect the brain and connect it back in I can feel the relay inside the brain click.

Never heard of that one before!
Standard procedure was to disconnect power and ground for 2o minutes.
But really is it worth it? That alarm must be at least 20 years old.

The car has gone weeks without any battery so that would of done it if that was the case.

Check the ground for both the alarm brain and the siren is good.

Does anyone know how to reset the brain in case I have to go that route?

At least one poster including myself has already told you.
The fact that the battery was disconnected and it still went wrong means you've had it.
It's a gonna.

Oh howei:
I think what I want it to know was how to reset it. The fact that the car can be without power for days and I can still arm and disarm with the remote tells me that the brain needs to be reset through other means.
It's ok if you don't know. It an old unit but really the only thing that it does not have is two way comm so if I can use it I would like to.
Does anyone know the procedure to completely reset the brain.
Thanks

Just to clarify, that there is no response when the battery is disconnected, correct. The other possibility is that here is a battery backup for the alarm or a battery backup siren. Unplug the alarm brain to reset it with a backup battery. If the vehicle has a Clifford backup siren with it's own internal battery, there is a key switch on the siren to shut it off.

Hey sparkie:
I don't think the alarm horn has a battery but I can check. The odd thing is that the alarm turns on when the alarm is just armed and it stops sounding when the alarm is triggered. It is just working backwards. I might have to disconnect every wire to see if there is a sensor doing this. The grounds are ok. Could a certain car battery do this? I have a big battery that is for an expedition hooked up to the car while I work on it.

As long as the battery is at 12 volts it will work to test the system. It is possible that one of the alarm triggers is active, but the alarm should ignore that input and alert you with some chirps that it senses an active trigger upon arming. Make sure that you use a digital volt meter to verify the grounds are good.

Thanks Sparkie:
Hey can I disconnect everything except power and ground and the unit arm and disarm? I already know that there is some kind of wiring problem because if I move the wires around the unit loses power so I have to check every wire anyway. If the unit still acts crazy with everything disconnected I guess that would mean that either the unit is bad or something is up with the horn.
