Re: 2001 S80 T6 Siren Module Replacement/Repair - How To

Thanks for a great article. I managed to get a new Siren from Ebay for £100. (Even came with new rivets!) Job took me about 1 hour.
Reset using the 3 times lock-unlock!

Fantastic site! Keep up the good work!
Roger.

I changed the battery just in time. Everytjing was as told here. 10x for the tutorial.
The only problem I had was that I could'n find exaxtly the same battery so what I did was to take the size of the original battery (Diameter 25.20 mm; Høyde 30.6 mm) and began surch in local shops. What I found is that there is enought room to place a battery with dimentions: 30/35/30. Hardly but possible.
So I bought two baterries 3.6V 300mAh sized 30/32/15 and made obe big: 7.2V 300mAh sized 30/32/30.
Here are some pics:

One other Idea: I was thinking about external placement of the battery - why not...
1. It will be easyer ro replace it next time;
2. Even a damage of the battery the main electronic wont be dammaged...
3. You don't need to surch for a battery in that small size. Just voltage and amperage.
What stopped me to do it was that in that moment I had no silliocone around to isolate ewerything as necesery... but I was decided to mount it outside the sirene box.
Good luck everyone and 10x to vegasjetskier for the tutorial.

Just replaced my Siren module.
Works again & the moonroof works !
I drilled out the tamperproof bolt. Replaced it with a bolt from the old module. The bold has a 12mm square head.
Opened up the unit like every one else. Corrosion.

I used a dremel tool to cut a slot in the tamper-proof bolt; it came out easily with a stubby flathead screwdriver....

Hi all. Is it possible to get rid off the damn thing (siren module) and still have the sunroof working? Is there another security module on the car that may still work? Thanks.

This is a great write-up and very helpful in understanding the issue and accessing the siren module. I offer the following because it worked for me and if you do not care about the alarm and/or siren anyway, it is the cheapest solution.

I removed the siren module and cut it open as described in the article, and found the described corrosion and broken wire. It was a Sunday a few weeks ago and after trying briefly to find an economical battery replacement locally, I decided that I needed to search on line. Since we still needed the car to use pending obtaining another battery I decided to clean up the parts and put it back in place so everything else would work.

I removed the battery, unplugged the siren, and then removed the circuit board. To clean in up in the hope of eliminating any shorts, I used Q-tips and vinegar to neutralize the KOH that had leaked from the batteries, and then Q-tips and alcohol to rinse/clean the board. I then replaced the board in the module, but left the siren unplugged inside the module and the batteries out completely. Since my original intent was to find and replace the batteries, I used electrical tape to hold the parted siren module back together and seal the split. After reinstalling the module and bracket, I used speed nuts and sheet metal screws in lieu of rivets for the inner fender so I could get back in easily.

What I discovered that afternoon is that with the module reinstalled, less the batteries and siren not plugged into the circuit board, was that now there are no false alarms - no lights flashing - no messages that the alarm had been triggered or that the alarm system requires service - no drained battery form the flashing lights and siren (weakly) randomly going off.

It has now been three weeks of alarm free peace and the only cost other than the time was some electrical tape, speed nuts, screws, Q-tips, vinegar, and alcohol.

The only thing I did not have on hand and had to purchase was the 6mm bolt to replace the security bolt that had to be ground out and I found that it may actually be possible to loosen the bolt from inside the fender (under the hood) without grinding it off. I found this because to remove the threaded portion of the bolt, that remained after I ground the head off, I had to use needle nose pliers to turn in out of the nut in the fender enough to get hold of it from below.

I do need to go back at some point and glue the module together and seal it with RTV or something similar. If you were to do that up front you will avoid having to remove the module again (not that hard without the security screw) and can use rivets to replace the inner fender.

Hope this also works for anyone else that just wants to eliminate the alarm issue without having to buy a new module or track down the correct batteries - good luck!

I just bought a used siren off Ebay and plugged it in to test it, nothing. Same as old one, no sunroof, showing alarm service message. Does the alarm need to charge up , if so does it do it just by being plugged in or does the car have to be running/driving ?

I want to cut this unit open and have a look but then i can't send it back to the seller.

Info for chap with sunroof malfunction, I read on another thread that there is a reset procedure which involves holding the sunroof switch fully up for a few seconds. This reset worked for mine!
