Ford Focus 2014 alarm

37
Posted 21st Mar
If anybody could help it would be much appreciated as I’m at my wits end.

Normally I would rush it to the garage where I got it but I’m working on the front line due to covid 19 so I’m stuck.

I purchased my 2014 focus approx 3 weeks ago, had a dash cam hardwired in.
Now this maybe a coincidence but 2 days later the car alarm goes off at random times for no reasons.
I’ve checked the footage and nobody is trying to break in, I’ve disconnected the camera and that hasn’t worked. I’ve opened all the doors, fuel cap and bonnet and still no avail.
Any ideas from anybody would be greatly appreciated

Thank you

Is it an estate, As my old vectra was an estate and had strange alarm issues.
My problem was down to the alarm circuit in the rear side windows. Looked like an a heating strip.
Over time it got hot and cold and cracked causing the alarm to go off.
the cure was to disconnect each window and join the wires together.
I used a scan tool to find out the cause, cost £15-£20 on eBay. Well worth the money

No it’s a standard hatch, first time I’ve owned a Ford Focus and I’ve never had alarm issues before 😞 looks like I’ll try and have to get it back to the garage somehow

Bonnet issues on …Bonnet issues on here.https://www.fordownersclub.com/forums/topic/60095-mk2-focus-alarm-going-off/


I hope it’s not the bonnet :/ I’ve had it opened and closed but that didn’t solve it. I just don’t want the alarm going off through out the day when I’m in work and worse at silly oclock when I need sleep 😞 will have to try and call the garage where I got it from and see if we can arrange for me to try and get it in.
In the space of 10mins the alarm has gone off 3 times! My dad is considering removing the fuse
One of my neighbors had this problem, anyone walked or car drove by the alarm would go off. I would think it's to do with adjusting the sensitivity but have no clue. Maybe take the fuse out and in and see if it resets.

Nobody has gone near if not even a neighbours cat 😞 sent dad out now armed with tools to remove the fuse. I really don’t need a naughty car at the moment
Have you checked that the windows are closed properly?
A draught getting in can set them off in windy weather.

Yep even checked the sunroof
In that case I would pull the fuse and deal with it when you have more time.

Well there is no fuse, so we are now baffled. The fuse is missing :/
One of my old cars, the alarm randomly used to go off and it transpired that it had a sensor in the door pillow. A spider had got in there and kept triggering the alarm.
Low battery? Parasitic draw? Could need a new battery if its 2014 and not had a new one

I’ve had no issues with starting the car or no warning signs? It’s keyless entry and both keys had new batteries put in at the garage

Hmm, check battery terminals clean and tighten?

My dad is out there with all his tools, Im Convinced it’s something to do with the dashcam, however now it’s unplugged and it’s still happening. May have to leave the car unlocked 😞
Can’t you just lock it without setting the alarm? Or have a look in the manual to see if there is an alarm deactivation button?

Nope, you can deactivate the internal motion sensor that’s all. That’s why we went to pull the fuse out but noticed it wasn’t there.
Maybe the dashcam is draining the battery too much and causing problem
it could have been fitted to a permanent live and not one that comes on with ignition maybe

Have you looked in the boot for water, felt the rear floor carpets? Not sure if yours is the newer shape but sister in laws 13 plate had this common problem with water ingress that could be effecting electronic modules
Reverse logic, put a fuse back in or cut the siren wire
but I did find this
"Ask on Exit"
You can set the information display to ask
you each time which level of guard you
wish to set.
If you select Ask on Exit, the message
Reduced guard? appears in the
instrument cluster display each time you
switch the ignition off.
If you wish to arm the alarm with reduced
guard, press the OK button when this
message appears.
If you wish to arm the alarm with full guard,
leave the vehicle without pressing the OK
button.
You'll have to find the setting in the manu (if it works, you've got something moving inside the car that the ultrasonics are picking up)

I have that message reduce on guard and we’ve been pressing ok so no avail.
It’s 2014 Focus Titanium.
We’ve checked all the floors and boots not damp at all and no condensation.
Well try and get my father to run it to Halfords to see about the love wiring in the dash cam, however if it’s been disconnected as in we’ve taken the dash cam off then surely it wouldn’t be still live?

The cameras a 5v device, with a box dropping the cars 12v to it, it could be putting something into the cars wiring, is it into a switched positive or on permanently, could the wire be acting like an antenna? Is it a piggy back fuse, maybe find another fuse to tap off?

We don’t know where the hardwire goes haven’t been shown. Will try and get my father to get it Halfords. I’ve had enough of the car now going off. Last night was the worse, my dad has been up all night with it 😞
Yes I had the same problem absolutely drives you nuts. It’s the bonnet catch! Apparently only ford can turn off the alarm completely

But the bonnet seems fine? What do we do?
Mine did to, sold it in the end as it was driving me up the wall

I hope the person who traded it didn’t do it because of that 😞 I’ll try Halfords first if not will try and get it back to the garage
Well dad visited Halfords today,there convinced it’s nothing to do with camera but shown us how to unplug it, so now it’s a waiting game to see if it goes off. Apparently it’s wired to the ac

Assuming by ac, you mean air conditioning, that doesn't make sense. In your original post, you said "I’ve checked the footage and nobody is trying to break in", so I assume it's been wired to an always on supply, which the ac shouldn't be.

That’s what the halford guy said wired to air conditioning unit. However the alarm has just gone back off, so its not the dashcam 😔 so now I’m going to try and figure out how to get it back to the garage where we got it from 😔

Try either a Ford main dealer or a car electrics specialist. It could be something quite simple. I wouldn't trust Halfords to check my tyre pressures.

It would. But it depends how much it would cost in terms of fuel, time etc. Try phoning Lookers and see whether they would agree to pay if you take the car somewhere local. You never know your luck in the current climate.

Either way it’s a hour drive to the nearest ford garage and same back to lookers, and unfortunately it would be down to my father as at present i only get Sundays off.

I put a custom aftermarket "zoom tube" exhaust on my car for a while and it pointed to one side, if I drove through the supermarket car park I'd set off numerous alarms on the side it pointed too. I've took it off for now an put the stock mufflers on whilst I fabricate a muffler to fit inside it as it was too obnoxious even for me.

On another car I had years ago a lorry or bus going past would trigger the alarm, do you live in a mid to heavy traffic area or is it the same wherever you park?

The problem with taking it back to the seller is they will just fob you off saying its the dash cam wiring, actually on that thought when you say you checked the dash cam and no one was near it was the dash cam actually recording anything? If so it may be set to record on movement detection, we have a doorbell camera that is set to do that and a change of light such as shadows or cloud passing the sun is setting it off, could it be something minor such as that setting the dashcam off, the dashcam then boots up putting a draw on the electrics and the alarm is picking up on a current/power change and going off? I know some alarms can do this so say you open the door whilst the alarm is activated, the interior light comes on and the alarm go's off. Go into your dashcam settings and look for a setting that records on detection or movement and disable that for a day or 2 and see if the problem remains.

An easy way to see if it does go off with voltage changes would be connect a wire to each of the battery posts and close everything up, set the alarm then place the wires on a spare car bulb so it lights up.
It’s parked on a side street at home and then when Im was in work it was the car park and today a public carpark at the sea front so all different areas.

We’ve disabled the dash cam as in unplugged the wiring from the fuse board and it still went off. So it’s not the dash camera.

We’ve checked all the keys as it’s keyless but it’s still happening.

Cleaned the bonnet and boot catch.

Unplugged the iPhone cable-just in case

Checked all the windows and sun roof.

Disabled the interior sensor guard.

We’re completely lost 😔
