hi Guys,

got an intermittent fault on my alarm, related to the boot closed switch.

Am i right in assuming that when you lock the car on the key the car should beep to confirm all is well?

do you know also if the boot switch is meant to make the connection when closed or open? as i might just fool the alarm if thats possible

No - its the other way around - when you lock the car it beeps to tell you a DOOR Is still a jar and not shut properly..

If the car still locks and sounds its a little easyer to pin point, it will be either of the rear doors or the boot, because if its a front door lock, the car will unlock itself again..

Anyones guess to which rear door lock it is.. unless one is not operating correctly.

Regards
Paul

i was advised by the previous owner that it is the boot that is at fault, so if i unplug that sensor it should be ok?

I DOubt VERY much, as the boot has a standard Solinoid for locking - dating back to the BX years!!

It will be one of the back doors as they have a more involved door lock with deadlocking..

On the subject of S2 Estate alarms, DickieG, in his blog, wrote:Just recently the alarm on my HDi had been going off so when I returned home on Saturday afternoon I took the opportunity to plug in my Lexia to find out the cause as one of the excellent features on S2 Xantia's is that the body computer (CPH) records the last 15 causes of alarm triggering. However it didn't turn out quite that simple as for some strange reason it took several goes to get the Lexia to boot up correctly (its been fine since ) once it got going it revealed that one triggering was due to the O/S/R door being open and the rest an open boot. As mentioned last week I'd recently had to repair one of the heated rear window wires where it enters the hatch so my suspicions led me to presume that the boot lock loom had suffered a similar fate so using the Lexia to display the alarms 'reading' of the door's status, I manipulated the wires in every direction possible but no matter what I tried Lexia said "Closed" so I left it at that if only to allow the fault to get worse and therefore be easier to trace later that evening,,,,,,,,,wakey, wakey hmm, best I use the key to lock the car then.

Jim pointed me in the right direction when I mentioned the boot lock problem's I'd been having on my HDi in that it may be a problem with the switch on the lock. After Jim left curiosity got the better of me so I connected up my Lexia to give live information of the door status which this time for a very brief second or so showed the boot to be open so I started pushing and shoving on the rear hatch and discovered that at various points the door status would briefly change despite the door itself being well and truly secure on the locking hook . Long story short, (finished working on it at 11.30pm ) I eventually traced the fault down to of all things a worn boot lock pivot hinge which was allowing the clasp to move from side to side sufficiently far enough for the micro switch to change the door status from closed to open better still I had a good spare lock in my stash of spares . With the new lock fitted no amount of pushing and shoving on the hatch causes a change of door status, long may that continue

So theres a micro switch hidden somewere

I know they still use the old Clunk Solinoid, but thats otherwise interesting.

Yes its attached to the clasp on the hatch, BTW since fitting the replacement clasp I've had no further problems.
