    Here is a photo of the GM module.

    VR Surgeon made a comment on another Thread that is certainly worthy posting here. It is:

    "In full disclosure the GM part will get rid of the light, but may result in siren not blaring in some cars... have had it in my car for 2 years and have had no problems.."

    VR Surgeon is correct! I have read the same thing but one person said it was because he had bent one of the leads inside the coupler. I have also read that others installed it without issue.

    Sorry for the double post but any more info on this VR???? I certainly don't want someone to buy this alarm module and it not work.

    This will fix the flashing alarm light that does not turn off.

    Grey Boxer just pointed something out to me in another Thread I posted today.

    http://www.ferrarichat.com/forum/showthread.php?p=141861298&posted=1#post141861298

    I want to make sure everyone knows this information came from a company I purchased some Ferrari parts from. They did not ask me not to provide it to anyone else, nor did they ask that I not forward it to other Ferrari owners.

    I was just forwarding this information to help other FChat members. This seemed to chap Grey Boxer since I did not post a disclaimer on it...so here it is!

    I will do better in the future and not post useful information I may come across!

    Oh, BTW Grey Boxer...I will take credit for the Google search if that is okay with you? I did that this morning from my own computer!

    From what I have learned researching the alarm module, it seems that the GM one looks the same, but it doesn't function 100%.
    From what I understand, the GM alarm will get rid of the alarm light when you drive, and it will also chirp when locking and unlocking the car (U.S. model only). But it will not sound if the alarm is triggered. The lights will flash, but it will be silent. I asked a few people in another thread on FChat to arm the car, then open the door. So far everyone that got back to me said that it was silent when they tripped the alarm. I don't know what you found, or heard about the GM alarm, but I just wanted to share my findings. I decided to purchase the fully functioning alarm for now. It was about $255 for the part and I installed it in no time!

    For rhd D in the vin uk market cars the 15213135 siren will only stop the flashing led. It does not chirp nor when armed will it sound when the door is opened. This is fact from personal experience. I have not compared the circuit boards for differences as the old one has been destroyed by battery leakage .

    The above should read "for rhd C in the vin"
    I have disassembled the original f005v00088 177148 siren and the gm 15213135. The circuit boards are the same. The main chip has different numbers on it. There is a eprom 93c46. I will read both and compare data. Will copy old Ferrari eprom if i can read it and solder to gm circuit board.

    When I was trying to trouble shoot a FOB I tried to order one of these from the internet and some of those links are obscure compared to buying something from amazon or ebay. I never got the part! If I was in need of this I might be tempted to go to the parts counter myself. Does anyone know what GM car these are for?

    The local Chevrolet dealer told me it was for a Canadian C5 with the alarm option package??? I have no idea if this information is correct. I just found the PN online and ordered it. It installed and works as described above.

    If the Eprom can be copied and rewritten to the new module, that would be great. If it can be moved and provide the same function, that is even better. Is it soldered in or pullable?

    I have a new one in the box. I bought 2 when I had my 360 and it worked perfect. Traded the 360 for a Scud. PM me if you need one.

    Findings I cant read the 93c46 from the Ferrari siren. I soldered the Ferrari 93c46 to the gm 15213135 siren. No chirp when arming and disarming. When the security system is armed and the door is opened the siren activates. The flashing dash led is out. There is no activation of the siren in panic mode with 3 consecutive fob button pressings.

    The price for this module from GM, or other sources, has increased to $300-$400.

    Get one from Mark at ferrarifobs.com and you get a new GM siren with Ferrari software. Have one in mine and it works perfectly.

    Thanks for the responses. I'm a bit confused about which element I'm replacing. I've seen several articles one for each box. Your post here refers to the alarm siren. Other posts have referred to the alarm module.

    On my 360 the alarm does not chirp, the red light is blinking when the alarm is NOT set, and is solid when the car is running indicating an alarm failure. Which of these modules should I replace to fix the alarm and turnoff the little red light?

    Forum posters mean the siren in all cases. Do not confuse "module" with "ECU".

    Some faults have similar symptoms, but 9 times out of 10, it's the siren which is faulty.

    Yes, the typical failure mode is the nicad battery inside the siren. Over time, the battery fails and starts leaking. The acid corrodes the circuit board, and then things get weird. Replacing the siren usually is the cure. Some have opened up the siren case and replaced the battery with success, but only if the circuits haven’t been damaged. Oh, and the battery is there to power the siren in case the thief cuts off the main battery.
