1989 rx7 gtus. stock alarm. the car is parked outside my house and every 5 minutes, i hear the alarm goes out. beep, beep beep, beep... etc. why is that? is it because when i lock the drivers door, i hold up the door handle as i close the door?

Kai

You have to do that to lock the door, and locking the door arms the system.

It's typically a CPU problem, IIRC.

so what can i do? its parked outside my house and the alarm goes off every few minutes and it stays beeping for about 5 minutes. im scared the neighboors will complain and stuff.

unless the location changed (or the puter is integrated somewhere else) my S4 alarm was mounted under the dash on the passenger side, right below the glove box.

Unplug the cpu, no more alarm going off randomly and killing my battery.

My '88 vert is not my daily driver, but I love to drive it. I finally got the alarm figured out and left it parked for about a week. Battery was dead when I went to start it up again. I was not aware that it drained the power that quick. I keep it under a cover out in the drive when not driving it. This heat may have taken a toll on a brand new battery. Of this I am not certain.

xUnKnOwNx

which cable do i unplug?

Icemark

It is probably not the CPU, but you could unplug the middle plug on the CPU to kill the stock alarm on a S5.

But it will also disable horn and a couple of other functions.

So the real way to fix the problem is to fix the offending sensor. More than likely it is either the hatch switches, or the door latch switch(s). The door latch switch is the door lock on the inside of the car. If they are out of alignment or dirty the alarm will false trigger.

And don't get confused by the people that are saying unplug the factory security brain under the glove box, that is only on the S4 (86-88) models and they obvously don't know enough to even answer your questions in this thread (or they would know that).

The stock alarm will take more than a week to drain down a decent condition stock sized battery (actually closer to 3 or 4 weeks without being driven).

So your problem is probably either an aftermarket security system or a current draw from some miss-installed aftermarket electronics.

or a just plain crappy battery, but fixing the alarm issue is a good place to start.

cleaning the door switches only takes a few minutes so i would start there.

dont know if its the same problem, but something similar happened with my 88 vert, and i replaced the battery and the alarm stopped going off, so that might be your problem.

xUnKnOwNx

the door switch from the inside may be the problem. i noticed that i was twiddling with the lock. (not actually locking it, but rather gently pushing it) i see the "security" light go on near the e-brakes. i also noticed that i cant lock my driver side door. i have to either hold the door handle up to close the door, or lock it from the inside from the passenger side. what can i do to fix it? i was thinking maybe if i get a new alarm? which i was planning to anyways. also will replacing the door locks work?

i just disengage the alarm by locking it from the outside with the key. i had the same problem you did but mine went off at random times.....like 4am

Icemark

Yep that is the way it works
No, the door locks work that way.

On all older Japanese cars, if you lock without a key (using the interior lock latch) then you must hold the outside handle up when closing the door. This is so that you don't accidentally lock the keys in the car and was common on Japanese cars until the mid 90's when the switched over to the lame US design of just closing the door.

The alarm also works that way. It must see the door locked inside and closed with the handle up. It will not arm when locked with the Key in the door.

xUnKnOwNx

so what do you suggest i do?
right now my temporarily fix is to unplug the battery.
im planning to goto an alarm shop later today and install an alarm and keyless entry.

Icemark

Lock the door with the key. Then the stock alarm won't arm and the car will be locked.

If you are installing aftermarket keyless and or alarm, make sure they hook up to the disarm wire with a relay or diode off the aftermarket system's unlock output, so that when you unlock with the aftermarket remote the factory alarm disarms too.

I have an 87 GXL with the security system that came on it. I understand what you were talking about with the inside door handle and am going to clean them when time allows and its not 95 degrees in my driveway (my vert project is in my workshop).

My alarm goes off at random times when the car is not locked. My wife may drive it, come home and park it in the garage (garage door closed and car not locked). A couple of hours later the alarm may go off. Do you think it is the same door lock sensor issue?

Thanks!

Icemark

Won't go off unless the doors are locked and then the last door closed with the outside handle held up.

If she just locks with the key it shouldn't be arming

tekgraphx

Hmmm...

I understand what you are saying, but most of the time when the alarm goes off it is sitting in the garage and is not locked. After I turn the alarm off (with key in ignition), I jiggle the inside door lock and you can hear it chirping. We never hold the handle up when just closing the door, only when locking it.

Confusing....

Icemark

sure it is the factory alarm going off??? How are you disarming it???

tekgraphx

I know it is the factory alarm because we bought the car new in 87 and have owned it ever since.

The car is not locked when this happens and it may have been sitting in the garage for hours before it goes off.

Since the car is not alarmed or locked we generally get in, put the key in the ignition and turn the key to "on." That seems to stop it.

Thanks!

Icemark

Then it is not the factory alarm.

The only disarm for the factory system is to turn the key in the door (or trunk) to the unlock position.

The factory security system does not disarm from the ignition key being turned on (an infact should only trigger the factory alarm, if the door was not unlocked with the key).

it has to be the factory alarm because i installed a clifford g5 solaris and that almost never goes off. but the factory alarm keeps going off. and the reason i know its a factory alarm is because of the red/orange light near the e-brakes. it says security and it usualy lights up in a reddish orange. AND my headlights flip up and start flashing. (total waste of batteries). my factory alarm still goes off even with the clifford alarm installed. however only the factory alarm beeps.

i disable it when i stick the key on the PASSENGER side and turn the key right. it has to be passenger because if i try to stick the key in the drivers side. i cant lock or unlock the car. i cant turn the key. i think the locks are kinda f-ed up. then a few minutes later, the alarm goes off again.

i was at a bowling center the other day. and the workers had to make several annoucements about a rx7 in the parking out and the alarm is going off.

i disable it by unplugging the battery. thats the only solution i can come up with. but im thinking im gonna bring the car to the place where i installed the clifford alarm. and tell them to disable the factory alarm all together.

Icemark

Nope, factory alarm does not pop up and flash the headights either. Only flashes the hazard lights. Now many aftermarket systems can be wired to flash the headlights... but Mazda does not.

And the Mazda security light is Orange. there is no Red in it at all. Redish Orange suggests that there is a red aftermarket LED (the kind 99% of aftermarket alarms come with) stuffed in the housing. The Mazda system will flash the Orange security light once every 3 seconds... most aftermarket systems flash every other second.

And you will not be able to disable the factory alarm on a S5. The alarm is built into the CPU. The only way to disable it, will also kill other functions like the horn and key lights and that is unplugging the power to the CPU.

Now if micky mouse wired in the clifford system and didn't hook up to the factory disarm wire (which they should have).. that would trigger the factory alarm when you opened the door.

It sounds like you have a passive system piggybacked onto the mazda system.

xUnKnOwNx

i tried to disable the alarm by manually locking the door with the key. but the alarm still go off. how do i rid myself of this alarm?

Icemark

It is not a stock alarm, so you must locate the alarm brain and remove it.
