Passenger Door Central Locking

Post by kiwi »

Ok so replaced all the locks when I replaced the ignition barrel yesterday, I actually now have for the first time a Passenger door lock that opens with a key (last one had been screw drivered).

Noticed though that the key does not activate the central door locking on that side. I cant remember if that is a standard feature or should it actually work?

Psgr front door doesnt operate the central locking on any of my cars, so am presuming thats standard across the range, unless someone has modified theirs?

An old topic really :D

Seems that many RHD Citroens were never fitted with the passenger side CL sender switch.
And over here in LHD land its the opposite : seems in general to be fitted on Citroens here.

Its a lock position sensor switch with 3 wires fitted to the CL motor in the door that makes the difference - thats all.
Unfortunately the CL door motors are mirrored - so they cant be swapped from one side to another.

:? I was under the impression that the left hand door input to the central locking unit had been lifted to use for the remote receiver unit when that was introduced here. Are you saying that left hand drive cars have remotes and the ability to central lock from the passenger door :?:

You are correct Way2Go.

The driver's door always operates central locking (regardless of LHD or RHD)
If the car didn't have factory fit remote locking then the other front door also operated the central locking.

Citroën "lifted" the signal wires from the passenger door to operate the remote locking since there are only two pickups on the controller.

Ok I so my wife was right and I was wrong :oops:

So having the remote sensor do I assume by what your saying makes a differance? Not that mine works properly despite new batteries you got to be sat on the windscreen beside the remote to get it to work anyways.

:? my central locking on all bx's that i've had have operated from both doors :D

from reading this post is it possible to retro fit remote central locking to the later bx's then :idea: :?:

It can be done but probably easier and better to do it off the function in an after-market alarm package. You also get the benefit then of a radio key so no getting wet while you get the angle right for using the bx infra-red. :D

Whats that "lifted wire" story about ? :lol:

All CL control inputs are parallelled. No need for a separate input from each control originator.
In my current daily BX (tri) I have key control from both fronts - AND a remote :wink:

Refers to the where the CL wiring is not connected for functionality on the passenger door. :roll:

A curious statement! The wiring is indeed paralleled but only presumably in this RC version to allow for handing of the car. Aren't the diagrams the same for LHD & RHD? If you look at the diagram in Haynes then it shows an absence of switch on the right hand door lock - but we know that exists on RHD cars, don't we?

As the lock signals are achieved by grounding one of the inputs to the CL unit while the other is open (probably hung-high) then logically you could not achieve the necessary command by grounding both inputs at the same time as in your parallel scenario with lock switches opposite when the key is turned.

Also the infra red lock unit is clearly shown with it's own pair of lock inputs.

Well that's a bit of a conundrum isn't it? It would appear that you have a non-standard situation on your car possibly retrofitted at some time with additional relays in place to correct the logic. Or when you say you have a remote is it the standard Citroen infra-red type? :?:

what he said.

Of all the BX's I've had (36 to date, 37 next week) not one with remote central locking has CL from the passenger door.
Every one without remote has CL from both doors.
The original Cit wiring diagram supports this, so either Danish spec cars were different, or it's been modded the same way I did my mate's...

This is making some sense now.

The BX16RS has CL operating from the Passenger door

The 19TZS does not BUT it has a remote control

Just to satisfy myself now its caused even more confusion I am taking that trim off again incase I accidently knocked a cable.

All controls are parallelled. Period.

There is a control input for close, which can originate from either left doorlock, right doorlock or remote receiver.
You could add as amny secret control switches to make a close control input - parallelled to the existing ones.

There is a control input for open, which can originate from either left doorlock, right doorlock or remote receiver.
You could add as many secret control switches to make an open control input - parallelled to the existing ones.

If you think you can achieve open and close controls by paralling these 2 opposite controls together - then you have really missed the point.

The operation is by brief ground connection - with pull-up resistors on the control inputs of the control unit.
Diagrams or schematics in Haynes are "typical" given for a certain model. Not to be taken as for all models all years.

I'm really sorry that I have a LHD BX which is non-UK compatible according to the given Haynes schematic discussed.
I do regret that I ever purchased that BX.
I promise I'll thoroughly examine the CL lock control configuration before I buy my next BX. I do promise it wont happen again. I promise ...

Hope you all can forgive me that I own and drive a BX with just slightly more functionality than yours.
At the nearest possible opputunity I'll promptly and without hesitation downgrade my present BX's CL lock control functionality to match what you insist is the only and true BX installation possible in the world - of all BX'es.

I'm sorry. I regret.
