Alarm System Service Required
Just started receiving this pop up message in my DB9. Funny thing is I removed the module in the trunk years ago when I did the stereo upgrade. Erases OK with the T1 method. Is this a mileage related pop up? Anyone have a clue?

I got that problem when I'd let the battery go completely flat for weeks. Apparently after the battery goes flat, the battery in the alarm sounder goes flat, and that triggered the fault. Fully charging the battery didn't fix it, it needed AM to clear the fault. It could be that your alarm sounder battery has gone bad. Do you have any diagnostic reader that can give you more info?
|
If that battery is inside the alarm module in the trunk then there isn't one as I removed it. The battery never went flat as it's always on the ctek. It's as though the message is part of the car's software designed to pop up at a certain mileage. It's like a doctor saying you have a bad appendix but you've already had it removed. I have a reader which I will give a shout but I'll be surprised if it shows anything.

Alarm module/siren is not in the trunk, located in the LH rear wheel arch. If disconnected message will be on immediately.
|
I found my module in the trunk. I removed it about 4 years ago and never had a message. Messages just started appearing yesterday. Obviously someone had been in there before.
|
On my 2006 DB9, the module is in the rear of the LH rear fender well. It's a volvo module. Found it on Alibaexpress for $80 delivered. Mine gave me the warning when the battery was dead, charged the battery, then disconnected the battery and put the new module in. Problem went away...
|
does the battery in the module, cause the remote door locks not to work as well?

IIRC it's an easy to find Ford part: 6G9N-19G229
Common to AML, JLR, Mazda, etc |

Common to AML, JLR, Mazda, etc I bought a used Volvo alarm, opened it, put in a new (and much bigger) battery. It was kind of a PITA. |
I bought mine on Aliexpress - search for the DPQPOKHYY For Land Rover Discovery 3 Alarm Siren 7H22-19G229-AA ... Direct drop in replacement on my DB9. I note that it's gone up $30 or so since I bought mine.

Hey guys I'm in the process of fixing this. My alarm module was in such good condition but once I opened it up the battery had leaked onto the circuit board. I've cleaned it up a bit but don't know too much about electornics- can anyone lend an opinion?
Is this circuit board fried? Or can I connect a battery to it and throw it back in the car? I've marked where the positive and negative used to go! Thanks! https://cimg1.ibsrv.net/gimg/www.6sp...6e514a0983.jpg https://cimg2.ibsrv.net/gimg/www.6sp...7eb1a25c7.jpeg https://cimg4.ibsrv.net/gimg/www.6sp...4b19db4e76.jpg |
About 2 years ago I opened mine up to replace the batteries. I had to clean it up and check it for continuity. It's worked ever since. I'd give it a shot if the board is not physically damaged and there is continuity in the area that "looks" bad. I did have to use different size batteries but the specs were the same. I believe WILDCAT did a "how to" thread on this topic a couple of years ago. Good luck!

Scuderia shows the same part # for the Rapide as in my 06 DB9. I replaced mine from Aliexpress.... YMMV!
