It is behind the bumper just in front of your passenger tire. You must remove the plastic liner that is held in by rivets.

I checked and i just removed the bumper last month there is no alarm there. maybe that is only on the euro models?

Are you sure the car is alarm equipped? [Does it have a red LED on the dashboard?] It is possible that the car was shipped without one. It is also possible that someone removed the siren. Did you see the electrical connector for the siren? It should have been on a clip next to the mounting area in that right front fenderwell area.

okay guys sorry i somehow overlooked the module! I got it replaced i had the hardest time ever trying to get the security rivet out of the module. I never actually did get it out i had to zip tie the module to the body. I tried every tool there is. Wel thanks to the OP for the great information. i can wait to rip it open and see what was actually wrong. I will post pics when i do.

Does anybody know if you can just jump the wires going into the siren module without having to remove the module? To get rid of the annoying "Alarm System Service Required" message. And if so, would the sunroof still work?

Are there just 2 wires going into the module, and could you jump them to disable it? If more than 2, which ones (what colors) would you jump?

Yes, I know this would disable the siren but would save you some $$$ and time.

Thanks...

I'm afraid not. The siren's not just an on/off device, it's signaled over a serial protocol called Volcano Lite or LIN (Local Interconnect Network) depending on the year. Do not jump any of those wires, as there is the possibility of killing your UEM, and that's real money to put right.

Hi,

Do I have the possibility to test the siren module without installing it on car.
I have bought a second hand siren module and I want to test it before mounting it on car.
Maybe there is a way testing it with the multimeter?

Thanks and regards,
Tudor

Just thought I would post an update, it's been what like 18 months or so since I replaced the module and so far no issues. Not bad for a $35 used part with a lifetime replacement warranty from Eire VO-VO !!

My 03 S60's battery was always loosing it's juice so I decided to remove the alarm using this write up. Sure enough, the battery leaked and blackened the board. I'm still searching for a replacement siren battery and haven't found one similar to the original.
I just called the dealer and it cost $243 and change + tax for a siren. Ouch! I'll try to order a 7.2 volts battery from the website mentioned above and see if the PCBoard was not fried. The short on the wiring was probably causing the battery drain cuz the car started2 days after I removed the siren and the battery is usually drained after 2 days if car is not used.
The question now is, do I have to replace the siren if I'm unable to fix it? Will other elec'l components be affected if ECM detects
a missing siren? There will surely be DTC like Siren Module problem but I'm not concerned with that. Any thoughts on this?
