Title: FAULTY ALARM - HELP NEEDED
Post by: scarecrow on 12 September 2012, 11:58:18
I have an 03 2.6 and it has developed an alarm fault.
There are so many posts on this topic I have become totally confused on the solution
The alarm rarely goes off during the day - usually it's in the middle of the night
It will reset - at first it just needed the alarm unset and reset with the key but now it seems to involve more and more opening and closing of doors and the bonnet or just leraving it unset.
I used a cable tie to set the underbonnet switch right down but this has not resolved it.
Is the next step to disconnect the power sounder or to remove it completely and also to remove the dedicated horn?
If I do this will cut out the fault or will I still get the flashing lights that accompany the horn?
If this will not resolve it would a code reader identify the fault - Argos sell one for about £90

You don't need a code reader, your foot can do it ;)

Has your power sounder been removed? Its under the scuttle, drivers side.

Though an EBDOII code will talk to your DBW 2.6 Omega, it'll only do engine codes ...... and the pedal trick on your car will do (almost) the same for nothing  :y :y :y

Whilst it could be completely different from your cause (I had no flashing lights), I did have this a few years ago and had to keep going to the car park to silence the alarm (2.6 2001) the issue has gone away (great description I know). I eventually got it to the bonnet switch. I didn't replace it, simply manually operated it a considerable number of times and the problem has resolved. May be worth a try on yours?

OK, a few more Q's, sorry.

The noise it makes, is it horn like, siren like, or both?


Further diag steps:
UNPLUG bonnet switch by unclipping the connector on the bottom.
REMOVE powersounder.

The noise it makes is siren like - quite diffrent from trhe car horn

new thing now happening -- one of the keys stopped working so replaced the battery and then it was OK -- alarm has just gone again and the key is not working, no led flash when any of the thgree buttons pressed -- alarm cancelled with other key.

IT'S DRIVING ME POTTY - ANYONE WANT TO BUY THE CAR? ONLY DONE 73K MILES, CURRENT MOT, RUNS WELL DAILY, VERY GOOD CONDITION FOR THE YEAR!
I'LL BE VERY VERY SORRY TO SEE IT GO BUT I'M NOT TECHNICAL OR MECHANICALLY MINDED AND I'M ASSUMING A\N AUTO ELECTRICIAN OR GARAGE WOULD CHARGE A LOT TO FIX IT

As RobG says bin it (or rather remove it and chuck it in a bucket of water and leave for a while!!) :y
