Alarm going off ??

[Ean Austral]

Gday All,


I have read of people having the alarm go off for no apparent reason and it turns out to be the bonnet sensor that has been the issue. It seems that they get a message saying bonnet open or something in the message centre.


Is this correct ? and when do you see the message ?


Our alarm has gone off a few times today but cant see anything on the message centre or any faults logged on hawkeye.

Haven't had those symptoms myself Ean. Isn't related to those cable ties is it?

They shouldn't be an issue, they are a fair way from the latches and the bonnet comes no where near them when closed.


I pulled the plug on the bonnet alarm sensor and sprayed it with contact cleaner then some WD40 on the latches so see if that does anything.


I could short the sensor which is most likely my next move but all the posts I read about the bonnet setting off the alarm says a message is displayed so I am confused about that.


I remember a fly setting off the D2 sensor when it was inside the locked car , but couldn't even see anything like that inside this time.

Well at least it lets the neighbours know you're home. :D

From my experience the message only comes up if the switch goes open when the ignition is on. If it is off and locked the alarm sounds but no message is displayed.

A paper clip shorts out the connector and no more alarms.

Yep , that's my next step , will short it out and leave it for a few days and see if it does it.

If you get stuck Ean, SDD can read the alarm trigger history. Not many other things can.

OK I will bite - what is SDD ?


something tells me I have left myself open for some form of jokes here , but lets find out.

SDD is the Jaguar/Land Rover dealer diagnostic software. As I said....if you get stuck.:D

Which the local dealer could not get to program/learn the keys of my D3...

Seriously? Useless buggers!

Removing the question mark would be entirely appropriate...

I had an issue with my D3 bonnet switch and didn't have the error message on the dash. Did the paper clip trick (with a piece of wire) 18 months later and it hasn't gone off again.

Hmm,mine once went off in the D2, at 2.00am in the morning at the Mt Dare campsite.

Lots of F words and a heap of very very unhappy campers.

It was a large moth flying around in the car that caused the issue.

As Sheerluck said,with the right tool you can detect what is triggering the alarm.

One of my door catches was replaced under warranty as it set it off a couple of times.

I did the paper clip, covered it with a latex glove finger and gaffer tape about 3 years ago. No alarm issues since.

Hi, I'm experiencing the same issues with my RRS and the dash screen reads bonnet open. Can someone tell me where the bonnet sensor is and which plug needs to be shorted. Pictures would be great.
Thanks Andrew

Andrew, it's pretty easy to get at - Remove the grille for better access. The sensor is underneath the left hand bonnet catch (as you are looking at it). You'll see a cable attached to the bottom of that left hand bonnet catch, unclip it. Push an unfolded paperclip, or a thinnish wire into both the two female cable connectors.

Job done.

Apart from putting the grille back on.

[Ean Austral]

I must have done it the hard way by not removing the grille. It's Under the drivers side bonnet latch is a plug with 2 wires going to it.

Took about 5 mins to do.

[sheerluck]

I wouldn't say it was the hard way Ean. You may well have added about 90 seconds to the whole process though. :D

I better not let the boss read that , she would add another 20 jobs to the list in that 90 seconds,:p:p

I had the 'Bonnet Open' alarm come up on the dash 3 times from the corrugations on the Plenty Highway.
Each time it was correct that the bonnet catch had come open but not fully released and you couldn't see any issue from inside.
So if the passenger side had opened I would not have known.
I wonder if there is an adjustment required. It seems to close as normal and only did it on the corrugations.

I had the same thing from passing a road train a few years back, never happened again on or off road.


Never tried to adjust it just thought I may not have closed it correctly to start with.

I had my alarm going off randomly a while ago. Bonnet sensor appeared to be the cause - in the end I had a bonnet open message when the engine was running and the horn gave a little beep everything I locked the doors. I simply removed the switch and shorted the wires together and no more issues now. Can't think of a good reason to bother with replacing the switch either

Thanks for all the replies, will short out the sensor and hopefully stop the annoying alarm going off for no reason.

Damn, wish this had been posted week before last. Had the error message pop up from time to time, as well as the alarm sounding. Paid to replace the sensor (only comes with a latch apparently) at a cost of over $100 while in for a service. Paper clip would have been much cheaper.

Got the daily double as also need to replace brake switch as is causing "restricted performance" message to appear. No ill effects other than the message and the yellow triangle of annoyance. Just waiting for part to come in for third trip to dealer inside two weeks. Second trip was to pick up my new RRS (he says smugly).
