BogMonster Posted June 13, 2008 Share Posted June 13, 2008 Welcome I think you have tripped the crash sensor somehow, this unlocks the doors, disabled the central locking and makes the hazards flash and is designed as a safety feature to assist in an accident. Normally you just need to switch the ignition off and back on again to reset this, unless you actually damaged something. I am not sure what controls the "crash setting" in terms of which ECU but I guess it is the one you dropped your screwdriver on It can sometimes be tripped by a bad cattle grid or a big pothole in the road but should reset. If ignition doesn't work I would try disconnecting the battery and see if that clears it. Quote Link to comment Share on other sites More sharing options...
pinny Posted June 13, 2008 Share Posted June 13, 2008 hello and welcome as bm said it sounds like the crash sensor i had this a few months ago i think it was reset by turning vehicle off and on a couple of times, i couldnt lock the doors with the fob and the hazard lights stayed on chris Quote Link to comment Share on other sites More sharing options...

discojmz Posted June 13, 2008 Share Posted June 13, 2008 Ive done this before. doesnt take much does it. in the end, I popped into the yard, came back and my dad had fixed it just by disconnecting the battery (both terminals) and leaving it off for a while Quote Link to comment Share on other sites More sharing options...
PEASEY Posted June 13, 2008 Author Share Posted June 13, 2008 yeah and isnt it annoying,the point you made of removing the battery for a while i havent done i just pulled the cable off and put it straight back on,im going to try that before i go dismantling in the morning,sometimes you just miss the simplest things,cant belive i didnt think of that myself,fingers crossed thats the answer mate thanks.

PEASEY Posted June 14, 2008 Author Share Posted June 14, 2008 well i tried taking the battery leads off and still no joy,i removed the crash sensor and took it apart,checked the various bits and bobs in there reasembled still the same,until my yongest son,ben who is only 4 and was watching dad trying to get himself out of some ever deepening brown stuff,pushed down the bonnet alarm sensor while i had left the ignition on and they stopped and the central locking has started to work again as well.its about time he started to pull his weight rather than wandering off with that all important spanner or bolt that i spend hours looking for and swears blind he hasnt touched it,only for my mrs to pull it out of the washing machine all shiney and new looking.one thing that did puzzle me though was that it wouldnt reset with the bonnet shut!oh well its sorted now and i would just like to thank everyone who replied to my post,thanks paul.
