When faced with the "Alarm System Service Required" message on the dashboard of a 2000+ Volvo S60/S80/V70, the problem is almost always the siren module. The siren module is located on the passenger side of the vehicle, behind the front bumper cover in front of the wheel. It is encased in a riveted metal box that prevents would-be thieves from damaging the module to silence it. Inside of the siren are rechargeable batteries that, by now, have likely failed and cannot accept a charge any longer. In some cases, the batteries leak and destroy the module's printed circuit board.
Watch the video above to learn how easy it is to replace the module if it should fail.

Thanks for the video! I just did this repair yesterday and it took less than an hour thanks to the instruction. One thing I did slightly different was use a dremel with a cutting disk to make a slot in the shear screw and then used an offset screwdriver to unscrew it - it worked slick. After the repair I took the old unit apart and the circuit board was partially burned coming from where the battery contacts were. Also, count the number of rivets you need to put that wheel well cover back, I was 1 short. I ordered the alarm siren, shear screw and rivets from FCP, fast shipping even during the holidays!
Was that module interfering with any other modules?
The reason why these fail is because there's an NiMH battery inside the siren that stops holding a charge, thus prompting the "Alarm System Service Required" message in the instrument cluster. If the message is neglected, the battery in the siren leaks all over the circuit board, which can cause other problems like stopping the sunroof from working. You can also test the siren by locking the doors, waiting 20-30 seconds for the alarm to arm and then pulling up on the door lock pin. You should hear a high-pitched wailing. The panic button on the key fob does not trigger the siren, just the car's horn and the hazards.
My XC70 got the "Alarm System Service Required" message in the dash. When I tested the siren, the hazard lights flashed, but there was no sound. Instead of buying a new siren module, I went to a salvage yard and took a module off of an S80. Then I bought a new battery off eBay, cut open the module, replaced the leaking battery (thankfully the board was unscathed, if the board is fried by battery acid, this won't work), then sealed it with hot glue and electrical tape. I didn't have to take the wheel off because of the XC70's raised ride height. That stupid message is gone and the siren works.
Jake B .......good info. Would the exterior lights stop working too?
Mine just stopped working yesterday.
Thanks
will disconnecting siren module re-enable sunroof?
You can access this also by the removing the passenger head lamp. I did it on my 01 xc70. It’s much easier.
This sounds a hell of a lot more reasonable. I'm going to try it.
But how the hell you removed that siren via head lamp place, when that stupid screw is behind siren in that case... ?
You remove just the plastic siren, not the whole metal bracket. Just slack top and lower 10mm bolts with a wrech. This doesnt work on the Xc90 though
I’m definitely not using a sheer bolt to replace mine. Thinking of the next guy lol.

Great demo as usual. The retaining bolt was a pain to remove. In the end I used a pair of channel lock pliers to get enough grip to get it to turn. Job took about 60 mins. Hope to get another year out of my 16 year old s60 thanks to FCP with this and other useful vids. Thanks again
You're welcome, Anthony! Keep that S60 going!
This was great. Just did this over the weekend on my 05 s60. Liquid wrench and the punch worked like a charm. Got an el cheap o Rivet gun at Lowes and it worked like a charm. Now my sunroof works again yay 😀
Probably worth checking if it works before torqueing the screw head off
This vid shows you how to do that: ua-cam.com/video/Wt1kp5HPgWc/v-deo.html
Do you need to disconnect the battery to install?
What is the estimated cost for the alarm unit and the total cost of this replacement TY
Excellent video presentation, also saw the one you did for the headlight bulb replacement, “Q” what size drill bit did you use for drilling out the rivets?
Cheers!
Why the security bolt? If your siren goes bad, from say the battery leaking, does a replacement need programmed to the car? Also, do you sell the siren battery? Thank you for all the Volvo videos. 2004 XC70.
Security bolt would be to deter someone from removing the siren and then breaking into the car.
I removed my bad siren and now my sunroof works again.
will disconnecting siren module re-enable sunroof?
hi, great video, same for Volvo S80 MK-II 2008 model?
Hi
I am a bit confused because the panic button on remote does the job so the car as well,but not when i lock the car and try to open it by hand(where i understand the alarm should kick in).
I have no error messages on dashbord. What shall i check or is the same problem as yours?
Thanks,
Volvo xc90 2005
How many hours labour will shop charge for this? I'm in the UK, would 1 hours labour cover it?
Hi, does it require any programming after installing the new siren alarm module unit?
no
Jay, thanks for the video. My siren module stopped working almost a year ago so I took it out tmporarily so my sunroof will work. Now, I in the process of replacing the siren module. I didn't keep the shear bolt so I couldn't chk its size. I don't need to replace it with a shear head. I was just gonna get a bolt from the HW store. Are you able to tell me the size/type? M6x20 maybe? Thanks.
I'll answer my own question. Yes it is an M6x10 but I replaced with with an M6x20 Allen button head. I'm sure you can use any head.
@@ggtaruc2578 which model car was it?
I took the siren apart on my volvo v50 2009. Inside was still perfect and the battery still gave a good volt reading. Does this point to a different problem on my volvo.
Do you need to get a software update for the new siren module or will it work out of the box after install? Thanks.
Works out of the box
Jay, does VIDA need to be programmed when siren module is replaced?
Спасибо. Всё чётко и понятно👍
Hi all
Does the siren need coding or programming whatso ever?
Hi Enver, because it is just the siren, it should not need programming.
@@fcpeuro
First od all, thanks for the fast reponse. That’s great to hear my local mechanic wanted to rip me off for another €150,-.
Volvo xc70 2008 i can't see the alarm can You help me
Jay,
I have the exact 2004 S60 AWD Volvo. I love it. This past week, my battery died twice and today, I got the Alarm maintenance required message. Checked the number 38 fuse, looks fine.
Questions, what’s the correlation between battery and a bad alarm siren? How does it drain the battery?
Is there any test to confirm it’s a bad alarm siren? All I have is the message saying “Alarm maintenance required.
And can I replace it through the removal of the headlamp, specifically for this model, 2004 S60? The rivet removal is too much for me to do.
Thanks in advance.
Going through the headlamp way: ua-cam.com/video/Wt1kp5HPgWc/v-deo.html
why wouldn't you replace that bolt with a regular bolt in case you ever had to chase it again?
george yannelis I'm guessing it's so that a thief wouldn't have an easy time removing and disarming the alarm. I'd rather have the removable bolt though like you said.
Is it going to grow legs and run off so that he has to chase it.
Curious, what’s the reason that they fail? I’ve replaced the one on my 2001 s60 but my 2008 s60 has yet to fail.
It's usually because of the internal backup battery that resides inside of the alarm siren assembly which starts to leak acid over time and pours directly on top of the circuit board.
If you dont fancy cutting the security bolt, heres a small trick (note that you can always remove the siren through the front headlight hole as well, on the S60, V70, XC70 and S80 but not on the XC90) m.ua-cam.com/video/Wt1kp5HPgWc/v-deo.html
If you have a c70 it was in the windshield blades compartment!!
Where can I find the part you're fitting at 3:40, the metal fender liner shield? I can't find it anywhere
Why not just use a regular bolt for easier replacement next time
Hi, what kind of rivets should I buy to install fender liner again
That's going to depend on the model of volvo and the attachment point, if you contact our servie team (service@fcpeuro.com) the team would be happy to help!
Wonder why they didn't show getting the plug out. 😒
Help needed! Same location on a 2008 s80???
Yep
Thank you
You're welcome!
Hi if i replace this module my sunroof it will work?
Y check fuses, and the sunroof and the sunroof does not work or emit noise
worked for me
Instead of installing the new shear-head bolt, why not sub it with a bolt you can easily remove the next time?
I think it’s to prevent a thief from easily disabling the alarm.
It's an excellent on idea and I did exactly that. These cars are older now and no one is going to steal them. On top of that the thief would have to know where this siren module is located so as to remove it first and then steal the car.
will just unplugging the module disable the alarm and allow me to crank the vehicle?
Nik Naks. The modules are interdependent. Other vehicle systems wouldnt work. Sunroof for example maybe others
Why you want to wank the car.
This is the other way. The other is to loosen the front bumper, headlight and support.
Can you just disconnect it until you get a replacement?
Sure you can, Kenny! You just won't be scaring any robbers away with the alarm siren not working!
@@fcpeuro thanks I removed the fuse last night until I can get a replacement siren.
@@kennyrose55 which fuse? Having the same issue but I don't like car alarms so don't want to fix it. Also don't want a dead battery.
@@tbituner put the following in the search: 'Pepperment volvo alarm siren fuse'. He shows where they are.
can you start the car without the siren?
Hi Schalz, you can start the car without the siren, however if the alarm is activated, you might not know since the alarm won't sound.
You're going to need safety glasses when you use that impact wrench, too.
…or just remove the alarm fuse. This is too much work. Nobody gonna steal my 07 Volvo.
Which fuse is the one for the alarm
I replaced it and it is still won’t start it makes a clicking noise the dash all light up but won’t start helppp
Now it says srs airbag service fml
@@ryanbechtle2799 I feel for you man. I know tis comment was 4 months ago, but keep in mind.. I just discovered my car was turning some lights on and off at random times in the middle off the night, my keyfob dont work, clicking sounds and my battery is draining out every time. Life is not all that bad! except i literally cant afford the insurance because the car is broken :'D
Typical flat battery. Still some power but not enough to turn the starter
Hello all s40 owners, I have 09 s40. I'm looking for the door lock/unlock wires to install a remote entry system. I found them to be black/red and black/yellow on the web. However, I cannot pinpoint their location. It said they are @DDM driver for module but I need their exact location on the fuse box to connect. Let me know if you know exactly where they are located. TIA
Hey how can i talk to you?
Hello Francis, you can reach Jay through email - jasonv1@fcpeuro.com
Get lost.
WHY ARE YOU REPLACING THE UNIT
You should lead with the whole saw blade grinder cutting thru steel rivets. Don’t waste our time just to pull out a high powered reciprocating saw
Thank you
You're welcome!
