    Let's start with the good news. Using Terry's excellent key fob guide, I was able to start my car using only the key. So my PIN works, yay.

    Not really bad news, but I was able to have an SDx scan done on the car, it came up clean except for a couple of alarm-related issues, see photo 1. The siren is definitely not connected up because it doesn't go off when the rest of the car is alarming (lights flashing). Also, the alarm LED stays on after all the other check lights go out, after engine start. It stays on all the time while driving, a distraction (photo 2).

    Could someone point me to the alarm siren location? It looks in the WSM like it’s under the intake air shroud (photo 3), but I’ve looked through the grille, no siren. I also looked in the air horn compressor, A/C drier, pisser reservoir cap vicinity behind the right headlamp ass'y, no luck. Sure hope the belly pan doesn’t have to come off…..

    Thanks Brian. Time to pull the right headlight out. Hope there's no booby-traps, first time wrenching on it.

    Wil, if you do a search on alarm or siren you'll find plenty on this. Below are a couple threads covering it. Second thread has a couple 550 pics of what you'll see.
    On the 575 had to remove the bottom panel and can't remember the details why. Seems I've read where the 550 comes out the top beneath that headlight. Headlight comes out easy just take some pics of fit or you may be wondering if you have it back in the same.
    The small front wheel house panel easily removed adds a little extra visibility if needed.
    Then there is the story of fix existing, replace with like Corvette piece (less expensive) or pay the Ferrari premium. The Corvette piece looks identical, but does not scream on some applications. It does work properly otherwise and lights only when it should on the inside.

    Bill, thanks, exactly what I wanted. I usually do a search before asking, just brain-farted on this one.

    Wil- Glad you got her started and those symptoms are indeed the rechargeable batteries in the siren giving out. Some have replaced those batteries, but I would actually recommend just changing the siren with either a Corvette one or the OEM Ferrari one. I believe it was Brian, our pro, who said he changed the batteries on a few, but too many came back so he now only puts in new sirens. Not worth the hassle.

    The later sirens last longer, if that makes you feel better.

    Nice to know the LED still works for start and Alarm ECU reprogramming with the siren out. I was not sure about that because it never came up before.

    The Corvette alarm is plug'n'play and, last time I checked, was under $100.

    Some report that the Corvette alarm will extinguish the LED and also chirp with arm/disarm but will not sound when the the alarm is tripped.

    Terry, glad to actually contribute even a little bit. You & Brian and all the others are just great.

    I've been doing my homework and I think I'm going to go with the OEM one. From what I've read, in the 550, the GM 15213136 siren usually will put out the LED, and chirp on engaging and disengaging, but won't go off when the car is violated. Kinda defeats its main purpose imo, it's worth the extra $300 to have it work as it should.... Out of curiosity I'm going to take my siren apart and see what we have. Could be something simple.

    Have fun- it will probably look like this http://www.ferrarichat.com/forum/135749733-post22.html


    There are many previous threads with suggestions for replacement batteries both internal & external

    Another thing I was reading about the GM 15213135 siren for a 550 is that it needs a GM? 180072 adapter/jumper cable to adapt the siren to the 550 siren connector, haven't found one yet.

    I replaced my siren with OEM. I am not a big fan of replacing parts that are not OEM just to save a few bucks.

    Just want to give a shout out to this forum--got my alarm siren out and apart in way less than an hour, after finding all the good stuff on here.

    Turns out another dead dog circuit board from leaking NiCd batteries (photo).

    I also included a picture of the old style NiCd battery just for grins, I know the good ones have gone NiMh or some such. Maybe good for cross-referencing...

    After reading and thinking about it, I'm going to pass on the GM siren, not because of the originality mantra, but because I gather it doesn't alarm when the car is molested. Kinda defeats the purpose imo. BTW, is that still the case as far as everyone knows regarding the GM siren--it chirps and turns off the steady LED light, but doesn't yell when it should (550 Maranello)?

    Wil- Seems to be random whether the alarm goes off with the GM siren or not. More of a problem on the 575 and 360 than the 550, 456 and F355 from what we have seen.

    Well, I'm now a member of the "This Alarm/Immo System Sucks" club. Bought the 'correct' Ferrari siren, carefully installed it--and it is behaving just like the GM type sirens are described as behaving. It reliably chirps once on arming and twice on disarming. It chirps three times and four times as described in the WSM. The lights all flash as they should when they should. The constant-on LED is now out.

    When I was playing around with it (nothing specific) after install, it would go into its full-on blaring mode. But hold the fob button for three seconds (panic mode), the lights flash but no siren. Leave it armed/locked and open the door with the key without disarming, the lights flash, no siren.

    I've attached a couple photos of the alarm and its box. Looks like a proper 'Ferrari' siren, no? The neatly etched number in the upper right-hand corner is 'F005V00654', the 'real' number is carefully melted out (upper left).

    Have I (hopefully) forgotten something simple, or just done something wrong?

    Wil- Most likely the batteries are not fully charged. Install it, let it charge overnight and try again to see if she will alarm.

    Some markets in the world will not allow an audible alarm (I wish that were true in the US) and the system can be so set. It may be yours was set that way.

    Has it ever worked during your ownership?


    The error page on the SD1 screenshot does not indicate a dead battery. It indicates a disconnected alarm siren. That needs fixing.

    It appears (if I read the date correctly) the the new siren in the cool yellow box with the horsey on it is more than one year old. I'm happy with the corvette siren. I don't need the alarm and If I could, I would excise both the alarm and the immobilizer.

    Brian, I'm a new owner to the car, it came to me with one of the old NiCd sirens that had oozed all over the circuit board, LED light constantly on, no chirps or sound at all.

    The VIN identifies the car as a full-on USA car. If it was on some ROW setting, it wouldn't chirp, no?

    The SD1 screen shows it as disconnected. Need to fix that first. Nothing matters until that red light is out. Dead battery does not cause that.
