Help needed central locking fault.....

[Craigus]

Recently on my LCR, my rear d/s door wont open as the deadlock on the door has a fault against it....


1 Fault Found:
00931 - Locking Module for Central Locking: Rear Right (F223)
27-00 - Implausible Signal


Now i dont want to take it to the stealers, i would like to get a 2nd hand module or at least get behind the door to have a look at plugs etc,

But the question is how do i get my door open again by bypassing the deadlock, i think im pretty much screwed, as if the last position the deadlock is in, is that its locked, and theres no signal going too it, i cant open it.

But surely there must be away around it because what would happen if the car was involved in a crash and the doors were still locked?

Please can anyone help

Cheers Craig

Anyone?

First, if the car was in a crash, they cut the doors open, they don't bother unlocking the door... The deadlocks also don't operate with the car running, it's only when the full alarm is on and the car is stationary.

Secondly, you can get the door panel off the rear without having the door open, as it is only screwed behind the handle and then it pulls away. You might have to work around the rear seat though. Once in there you might find an easy fix, like a popped connector or something. Certainly an implausible signal suggests it's having trouble communicating at all. Once you're in there, then you can look at other options, such as supplying a 12 volt line in a particular place to 'pop' the deadlock and allow you access to the door. But get the panel off first.

Thanks for the answer matey, i have got as far as taking the doorcard off as shown...

The problem lies in, i have removed the "gold" bolts all the way round and the 3 bolts holding the window motor on. and i can get the metal doorcard to move abit and i have tried to get my hand around to wiggle the connector, but its impossible.

I cant remove the metal doorcard off as i think the window runners are riveted to it,

I need to get behind that metal doorcard, so i can get to the c/locking control module and either try the connections or short across it to release the dead lock and can get the door open.

Can anyone shine any light on it how i go about it next?

Cheers

There is a specific process for removing the metal card, and you're correct in thinking its the window. The window motor and runners come away with the panel, so you can put those screws back in for now. You have to disconnect it at the window rather than at the motor.

Unfortunately I don't know how to do a back door. On the front door there are two grommets that are removed, you can then lower the window about halfway until the fixing screws can be seen. Those are undone, the window is wound back up and taped to the top of the door. Once the window is secure, the mechanism is wound down and disconnects from the window, then the whole panel can come away from the door.

I would expect the rear panel to follow a similar process, but I can't see any rubber grommets in your picture? Perhaps someone else can chime in and point out what I'm missing?

Right Slimy i got the panel off and the window slidow off and taped up,

I have another problem, i have a replacement part here, the problem is i cant open the door as the
existing door module has failed while the deadlock is on, I need to unlock that deadlock, so i can open the door and remove the failed unit, If i was to short a 12v source how would i go about doing that? or can the module be opened manually?

Cheers

If you have a replacement lock mechanism, the first thing I would do is connect the new lock to the connector, and see if that operates fine. If it does, then putting a 12 volt feed into the lock won't make any difference, as you're effectively narrowing the fault down to something inside the lock.

If that is the case (and I'm afraid it might be) I'd just be tempted to remove everything you can get to in whatever way you can. From what I can see on the internet, it seems a very common issue, with most solutions being to just dismantle as much as possible until the deadlock mechanism is reached, then remove it. Then once the door is open, remove the outer bolts and remove whatever is left.

Alternative options include destroying the lock completely with something blunt and heavy, getting behind the c pillar and undoing the striker, or even cutting the door off! But they all seem a bit excessive to me.
