Central door locking wiring

[Adelphi]

Hi - this is my second post on here...

I've just bought a 2nd hand 2007 Berlingo van, with the 1.6 HDi engine.

It has a few issues which I'm trying to rectify, and rather than it get all confusing, I'm going to ask about each one separately.

So ....

The van seems to think the front RHS door is open all the time, which means that when I click to lock the van, it opens straight away again.

Does anyone have the correct wiring diagram so I can trace through what should go where etc ?

I've taken the door card off, and can see that there are 5 wires going to a 6 way plug...

Pin1 : Thin Green ( 3050 )
Pin2 : Thin Green/Yellow 
Pin3 : Thick Blue ( 6202 ) 
Pin4 : <no wire> 
Pin5 : Thick Green ( 6212 )
Pin6 : Thin Pink ( 6292 )

I can't find a number on the green/yellow

I would guess that pins 3 & 5 are the motor, pin 2 is a ground, and pins 1 & 6 are feedback switches to the BSI ?


I've looked in the Haynes manual, but it doesn't align with what I have here.

Anyone any thoughts ?

Thanks

Hi there, 

I expect you have an M59, not an M49 due to the year. The M59 started around 2003.

Anyway, Green yellow is earth that's why there's no number. The diagrams are only correct in a Citroen software called ServiceBox. I'll pull up your door diagrams but I posted links to download ServiceBox as a VM version, if you know your way round a PC. I'll point it out later but it's stickied (pink section) at the top of the B9 section. 

The door locks themselves signal open or closed to the BSI computer and it then enables the locking. More complex than you might think these vehicles..

Schematics and full triptique attached.

And a picture of an M59 - confirm that's what you have. Once you do then I'll move the thread to the correct section.

Hi Zion,

How stupid of me - you're quite right mine must be an M59. It has the code number '11210' on the drivers side A pillar sticker if that helps confirm it ?

Thanks for offering to move the thread. I've posted another one regarding the door lock barrel that I'm also struggling with. Any chance you could move that as well ?

Thanks also for the pdf diagrams. They look correct for what I have I think. My only question is 'How do you know what part is what' ? For example, 6229 looks to be a switch, but what switch ? Is there a list on another document ?

The Master List Of Items...

It doesn't cover wires....you need ServiceBox for that. I'll get the wire details now.

3050 - Roof console
6202 - RH door locking and command
6212 - Boot striker control signal
6292 - RH door front unlock feedback

That number in the door pillar is just your build date encoded as an OPR number.

6229 is the lock / unlock switch on the dash.

Oh right... Is there anyway of knowing what any particular vehicle was built with ?

I'm more familiar with VW than Citroen. VW have a sticker usually in the owners manual with a load of 3digit codes on. These are all various options that that particular vehicle had fitted when assembled on the line.

Which is the switch to tell the BSI that a door is open ? Is it within the door lock ?

You need to pay Citroen for that privilege, €8 per hour on https://service.citroen.com and you can enter your VIN then get a build sheet.

You have to create an account, ideally they want you to be a business (garage) with a VAT number and submit full address and phone details. It's not intended for the public..it's up to you but the only way to get that info. VAT number can be declared as not applicable. It's not like VAG. I came from Audi-Sport.Net to here 12 years ago, I know the differences.

It will only say what functions you have, seat fabric, paint colour, battery capacity etc. But some bits may be useful like ABS, ESP etc.

Yes it's the door lock itself. Check the PDF I posted with the device idents in it. Every component is listed there. If it's in the diagrams, search it's number or name in the Citroen Components pdf.

I have work in the morning so signing off bud.
