HELP! First day of Spring and alarm won't STF

Wrecked944 · 03-20-2005, 09:38 AM

...sigh... I love my 1989 964C4 but the alarm has always caused me grief. Last year a relay came loose and it decided it needed two keys to operate (one in the door and one in the ignition). And now, after winter hibernation, I charged up the battery to give her the first test drive of the new year and the god d@mned alarm goes off constantly. The doors are unlocked and closed. I tried using two kets. I tried unlocking and relocking the doors again and again (but the power door lock mechanism dosn't work) and all it does is BEEP BEEP BEEP...it is driving me CRAZY. I have to keep the battery disconnected to stop the thing from beeping and needless to say this makes fast driving problematic. What can I do? I am at my wits end. At this point I'll gladly pay the dealer $100 per hour to fix it if I could only get the GD POS to the dealer in the first place. Aaaarghhhh!!!!

Here is a picture of my alarm module...if anybody knows how to bypass this thing, please send me a PM (so we won't be advertising methods for stealing 911's

)...

Assuming it doesn't snow I'll be at the Dive bar on Green St. probably on Wednesday night (i live about 100 miles away). If you want I can bring a Bosch hammer, a multimeter and the workshop manuals with me and we can try figure out what the real problem is.

Weeee!! With the help of the Pelican BBS I was able to bypass the alarm and get the car to finally shut up. So now I can at least drive the car without fear and get her to a mechanic or dealership without using a flat bed. This is pretty much the 1 billionth time you folks have saved my sorry butt.

And after doing some googling, I am finding that the alarm module under the seat is a common weak point in our cars. Apparently, it is a great place for water to collect and this wreaks havoc on the central locking mechanism as well as the alarm. So I'm gonna crack it open and look for obvious signs of corrosion before blowing the big bucks at the dealership. Can't hurt, right?

JasonAndeas: Dive Bar on Wednesday night, eh? Are you in a band? Playing a wednesday night "audition night" or something?

JasonAndreas · 03-22-2005, 12:52 PM

The Dive bar is way too small to fit a band inside there's not even enough to room for a DJ with turntables (we tried years ago), "The lucky Dog" down the street has an open band/mic night on Wednesday or Monday but I haven't been in years. Just meeting friends for drinks... The offer to help you with a hammer still stands, I'm in Worcester at least every two weeks for the forseable future (mostly weekends). With the right equipment these problems can be easy to diagnose.

Wrecked944 · 03-22-2005, 01:03 PM

Thanks very much for the offer. I genuinely appreciate it. But I think it is still too cold to work on cars outside (NOTE: I don't have a garage). That's probably why I lost my temper so quickly when it kept beeping - the last thing I wanted to do was perform auto repair in my driveway standing in a snowbank. I'll drive it around for a while as is with the alarm bypassed (I can always remove the DME relay when I park it to prevent theft which is actually more reliable than any car alarm). When the weather improves, then I'll try pulling out the central unit and performing some serious diagnostics. The "Frozen Fingers Auto Repair Clinic" is, I think, one of Dante's lower circles of Hell

Are you originally from Worcester?

I lived there and in Douglas for a couple of years so if you saw a black 964RSA driving around Worcester sometime during the past 11 years it was probably me. Hopefully I will be moving back to the area before summer.

I think the alarm system is working properly. The way to stop the wailing of the horn after the battery is hooked up is to use the key to lock and unlock the door. That's what the owner's manual says anyway for 964's.

I would take Jason's offer of using his Bosch Hammer to clear all the fault codes in your car though if I were you. The dealer won't be more helpful than him with the hammer.

Hi All,

Just bought a 964 tonight..... Ran great for a 150 mile return trip home. Put it in my driveway - locked the door with the key......

Went outside to take it for a ride - and it won't start!

The alarm seems to be active - lights flashing - try to start and the engine turns - but no spark.....

I am guessing it is in some sort of anti-theft mode.

I read the book - it says to unlock the door with the key to reset the alarm. Tried that with both doors. No improvement. Have left it sitting for 30 minutes - it does not seem to fix or reset itself. Even if I leave the door unlocked.

HELP!

What can I do?

Or - is there some way to bypass this anti-theft system - as I see another person above asking?

Please email me at claude@toolsineed.com with any information......

Thanks to all.

Claude

If the alarm isn't beeping, then it might be something else. Have you checked your DME relay lately? A blown DME can cause the car to crank endlessly but get no fuel. So no start. Are you anywhere near a Bosch Hammer? If so, it will tell you exactly what is wrong.

azcowboy · 06-30-2005, 08:22 AM

No - it is definately the alarm......

It only began as soon as the door was locked with the key....

It makes quite a flashing light show - flashers - inside - blinkers - door lock buttons.....

Any ideas how to get past this?

Would be HAPPY to have a Bosche hammer put on at the dealers - but I have to drive it there..... To drive it there means I need a Bosche hammer..... at the dealers...... But I cannot drive it there...... Because the Bosche hammer is at the dealers...... If I can drive it there they can fix it quick.... (laugh)

It is an endless circle it seems......

There has just GOT to be a way to bypass this silly thing! I am certain I am not the first and only person to experience this problem.....

Any ideas?

Thanks,

Claude

I know how to bypass the factory alarm (are you sure there are no after markets on yours?).

But sounds like your front trunk light switch might not be fully closing. There's a little bracket on the right side that is pretty floppy. If the gap is too big, the switch doesn't compress, thus your alarm thinks someone just opened your trunk. Try holding the switch down (use duct tape or an assistant), then lock the door.

If this works (or my super secret bypass trick, whcih I might share with you later) I'll gladly take the $100/hr.

azcowboy · 07-01-2005, 10:20 AM

Thanks to all for the replies....

I will CERTAINLY check the hood switch you mention. It is possible - there is a bra on the front of the car - which of course will have some impact on exactly how the hood closes.....

If you have the super duper - top secret - I could tell you but then I would have to kill you - answer to how to disable this silly alarm....

PLEASE.....

email it to me at claude@toolsineed.com

Thanks to all.

azcowboy · 07-01-2005, 12:06 PM

I checked the hood switch - it is working as normal - everything nice and tight - no problems in this area......

Wrecked944 · 07-01-2005, 12:40 PM

Have you looked the central locking unit/alarm brain box underneath the passenger seat? I had an alarm problem in my 964 that was caused by a relay coming loose from the unit. Might also make sense to pop the unit open and check for broken solder joints and/or corrosion. I think the box was placed under the passenger seat in 1990+ cars and under the dash in 1989 cars.
