Ford Repair Questions? Ask a Mechanic for Answers ASAP
Welcome to Justanswer, My name is Danny I am here to help.
Normally if this is being triggered its because of the actual door switches are not indicating the door is closed
The way these work is if the door is opened without the handle it will go off
So if the switch is not showing it being closed when the alarm is active it will do this
at this time, when the doors are closed, the dome lights goes off. Could it be a bad door module?
I am not sure how they wired in this aftermarket alarm
when a door is ajar and you arm the system, the siren chrips 3 times, letting you know that one of the doors are open
Does it go off even when its not activated?
only when it's activated
They may have installed proximity switches
They can put them on the hood
Also a level sensor of the vehicle is not level
where would it be located?
the car is level when its activated
The problem is if one of these has a bad connection or shorted this will happen
Have you changed the battery in the remote?
I have seen low batterys cause this
remote still works
Also does this happen all the time
Or only at a certain location
all the time anywhere
so a low battery on the remote could cause this?
I have had it happen
do you know which zone of the alarm was triggered when the led on the dash flashes 3 times?
it always flashes 3 times when alarm is triggered
This doesnt show me any specific details on the area
I know it can be a bad switch though either the one on the hood which will be in place normally on the actual front support will look like a little button that gets pushed when the hood is down
there's no pinswitch on the radiator support
I would honestly be upset and have a real shop that deals with alarms
Look at it
Because ford is out of there support here
They could have pretty much done anything
Without knowing its hard to trace the exact problem down
I would lube all the switchs for the doors with wd40
Replace the remote battery
When you do lube them close and open the door many times
Even though there is no light doesnt mean its not having a problem
keep in mind that the ford dealership installed the alarm using the OEM keyfob
That just seems ghetto
What did they do add a few sensors to go bad
no aftermarket switches
it was installed since my mom bought it brand new
Im thinking they just added the siren to the stock alarm
So they installed a regular system
As ok. That makes more sense
does every door have a door module?
maybe one of those module could go bad
There is only one for all the doors
is there a diagnostic tool to locate which switch is bad?
other than Ford's?
Not that I am aware of
I would start by replacing that battery
They have them about 4 bucks at walmart ect
but what if that's not the prob?
keep in mind that a zone on the alarm has been triggered
From my experience with the stock add on there is not anything to set it off other than the actual door switches
so there's only door switches on the alarm?
But I could be wrong here but I have not found one stock alarm that will go off unless the button is pressed or the door is opened armed with the window down
so must be one of the switches could be bad
Yes or the battery or the remote
Try arming it
Then pressing the panic
car battery has been replaced two months ago
The battery in the remote not the car battery
Im just informing you what has been done
Ok just wanted to make sure
Being on the PC and all some people may think I am talking about the car battery
Im a technician myself for 20 years
Yes I have had some weird things with the stock alarms
Even one went off on a audi by a garage
Some signals it was getting to the remote
im just unable to receive info on this particular vehicle
if we know what 3 flashes on the LED means, then we can focus on that particular zone
Let me look at some stuff on this alarm
There is a anti theft hood switch
So I suspect this is bad or the front control module which controls it
#10 is the front module
three of my co-workers used to be techs at a ford dealership and they all say it's hood switch goes bad
Yes this is wired into the hood ajar
Which is located at the latch
Violet orange coming from the front module to the switch then it has a ground
which is the switch on the diagram?
C189 upper right
Give that a shot
If it doesnt fix the problem let me know
If this was helpful please take a moment to kindly press the green ACCEPT button in the lower right hand corner. Thanks in advance Danny
You can follow up anytime free of charge
I should disconnect the hood switch and see if it would trigger or not trigger the alarm
that's what my co-workers told me
Yes if disconnected should stop it from happening
I dont have the vehicle right now but its on my way to my house
I could check it then
Great.. Let me know if you need anything else
thanks, will do
No problem.. Just dont forget to hit ACCEPT in the lower right if this is helpful only way I get credit.. Danny
