Hi
I am new owner of a crossfire (1 week) and as per my previous post, I am having trouble with alarm. After 4 days of no issues, the alarm keeps going off at random times. I have changed batteries in fob, I have also replaced the cars battery then because this didn't cure the problem, I finally removed the siren from under the plastic cowl hoping this would resolve issue.
The problem persists (obviously no siren noise but lights keep flashing), I am concerned that this will kill the new battery. Do these alarms switch off or will it keep going until it kills the power?
I have read various posts about siren batteries leaking and causing false alarms but I assume i have discounted this option.
I am now focusing on the switch sensors in either the boot/doors of glove box. Does anyone have any ideas please. Are these readily available to buy and easy fit or can I simply disconnect them? (not bothered about not having an alarm).
Incidentally, I did call the previous owner who is adamant that he never suffered this problem, I am inclined to believe him as I know for a fact that the car has been parked on his drive for months and the cars battery has not been removed as the bolts were rusted in place.
Thanks in advance for any ideas

The flashing light is probably caused by a damaged CLP/SSM in the trunk under the foam. Rain leaks into the trunk and collects in the well the CLP/SSM is in, the water ruins the unit and all sorts of things happen.

 

Thanks for reply, I will remove foam and report back.

 

x2 on that, I have just been through it !..............not fun, got a new pump for ~$325, and a new siren at $149...........fun times.
They are wanting $250+ for used pumps on ebay .......... :O(

 

I have removed boot trim and foam and inspected pump. No sign of any water in boot area (pump was in a foam surround, sitting on a rubber plinth). All very clean and dry.
I prised open the pump and again no obvious signs of dampness/corrosion. (i understand this was only a visual inspection and actually hoped to see it sitting in puddle of water and rusted).
The only sign of corrosion was near the boot handle and adjacent bolts also the motor for the spoiler has signs of water ingress (see pics)
I'm now wondering if water is effecting the sensor on the boot handle. I looked to see if i can remove assembly but need to remove the electric spoiler motor also. Does anyone know what will happen if I access this area and somehow disconnect the sensor, I am assuming its some kind of micro-switch?
I'm going to reconnect battery tonight and see if the flashing lights appear then open and shut boot a few times.
Would just love to identify the issue.
Amazing how you can love a car one day and then want to drive the b*****d into the nearest wall the following day!

 

Just an off the wall suggestion............when you put the battery back on, and the flashing starts, I take it that you can't silence it with either the unlock key or the panic button ?
just behind the CL pump, tucked away, and bolted to the frame, is the alarm module. Try disconnecting that, although I'm not sure if the CL will work then.
There is also a fuse that controls the alarm, but again the CL will not work if it's removed. These are things I tried before realizing my pump was dead. However mine had a foot of water in the trunk, and the pump was well wet.

 

Thanks for reply, really appreciate it.
The alarm/lights does stop with the key. Not sure I have a panic button on my fob (just lock and unlock buttons).
I noticed the box bolted behind the pump (wondered what that was).
I will definitely disconnect (wish I hadn't replaced boot carpet/trim. what a *** of a job to remove)
The only issue with pulling the fuse is that I can't get my key all the way in the door hole and so does lock/unlock. Guess there may be a bit of snapped key in there (I only have 1 key). Another job to do.

 

Just an update, I re-connected battery and at the moment, all has been well.
I also adjusted boot (trunk) latch as I noticed that the boot had play in it when closed. Probably not connected with the alarm issue but worth doing.
Will report back if problem comes back.

 

That box is the alarm that activates when the car is lifted. You switch it OFF when you have the car transported on a truck with the switch on the center console by the passenger seat heater.
The rust you have by the hatch lock is probably caused by water getting behind the cover over the spoiler motor, either the hoses that drain the spoiler well have come detached or the seal around the cover have failed. Fix it soon or you will have a worse mess to fix. Do not seal the cover permanently with silicone. See the post on the SRT fix, it is basically the same. CLICK
Water can get in the trunk when this seal fails.

 

Thanks for the info, I will definitely remove and seal. Becoming more convinced this could be the cause of the alarm issue.
