Remote Central Locking - Found original unit.

[sotal]

I was convinced that the Bongo wouldn't have had RCL as when you lock from the passenger door you don't get CL. However if you use the key in the drivers door it does all the locks.

Anyway - just pulled the door off and found the original OEM Keyless unit on the back of the door card.

I take it that means everything will be in place to make central locking work without having to install a solenoid?

This could be good news as the solenoid hasn't turned up in the post yet!

How would I go about connecting the alarm up to this? I have got as far as installing the alarm unit, shock sensor, ultrasonic sensors and the negative and fused positive. I was just having a look at what I would be faced with in the door.

You should find a door solenoid then which activates the drivers door lock, its this you want to find, then take the original key fob receiver out and connect the added solenoid to your unit.

I can't find an obvious actuator like the one I ordered from ebay!

Is it all built into one locking module? I've just been looking at the BWM on your site but can't really find much about the remote part - just the power locking itself.

[sotal]

Ok - Difficult to see but I think there is an actuator built in.

It has 5 wires going to it:

Red
Green
Green/White
Blue
Black

This is the manual:

Manual

It has a selection of wiring diagrams but I don't know which to use now!

[sotal]

At the RCL unit itself there are only 4 wires.

It has:

Blue/Red which is permanent 12v
Black which is GND
Red ???
Green with brown stripes ???


The key central locking still works without the unit connected so I presume the unit just does the job of activating and deactivating the solenoid. Just not sure what I have to do to make it lock - all talk of negative pulses etc - I have no idea what the bongo uses!

Any ideas?

There is no electrical connection to the Bongo Central Locking! It uses its own solenoid to mechanically operate the lock, which is the way all units do it on the Bongo!
You have a new remote receiver, which needs its central locking drive to drive the solenoid to operate the door mechanically, if itb handles a 5 wire unit then you might be able to get it to operate the existing solenoid, otherwise its simpler to remove the old addon and install your own two wire unit connected to the new system.

The unit fitted is a factory fitted unit.

In the link above to the installation manual it gives a variety of wiring diagrams but I don't know which one to use.

I've tested the wires. I have the following:

3 wires come from the car through the hinge. These are:

Yellow/Red (12v) - Connects to Solenoid
Blue/Red (12v) - Connects to RCL
White/Black (12v) - Connects to Solenoid

These are all permanently live when disconnected from the rest.


The Blue/Red wire provides power to the RCL unit

So the RCL unit has:

Blue/Red (12v)
Black (GND - connects to the window switch GND)
Green/Brown - Connects to the solenoid
Red/Black - Connects to the solenoid


The Solenoid has:

Red - Connects to the Red/Black of the RCL unit
Green - Connects to the Green/Brown of the RCL unit
Green/White - Connects to the Yellow/Red 12v from the car
Blue - Connects to the White/Black 12v from the car
Black - Connects to GND with the RCL unit.


Other than that being the basic connections I also noted that when the car is unlocked if I connect the Yellow/Red from the car to the Green/White of the solenoid then you can hear the locks try and do something (can hear the passenger door the most) (doesn't do this if they are locked).

If the car is locked then connected the white/black to blue in the solenoid makes the locks make noise again as if they are trying to lock again. Again making the connection doesn't do anything if the doors are already unlocked.

I'm wondering if this is the pulse required?

Does any of this help to work out how to wire it up?

I appreciate the help!

Thanks

I'm not aware of any standards for colour codes for remote locking, so not sure I can offer anything useful on the original setup or the specific wiring for the new.

It all looks so easy too!

Just got guess the right diagram then guess the right wires - what could go wrong!


I'm drawing blanks searching on the internet.


Do you happen to know what the wiring is like for non rcl bongos? Do you know what wires go from the door locks to tell the other door locks what to do?
I'm guessing it is the yellow/red and the white/black wires?

I'm guessing the RCL unit gives out a signal over the green/brown and red/black wires to move the solenoid - but I don't know if this is a timed pulse of positive or negative or some other kind of signal?!

Then as you say the other side would most likely just be mechanical and would operate because the solenoid has moved.

I might just disconnect the solenoid and have a play with the red and green and see if I can make it move. If I knacker it then I'll use the aftermarket one when it arrives. My only worry with moving over to an aftermarket one is that the system to detect when the door has been unlocked / locked is built into this one so I would still need it in some fashion - would probably have to fit both in?!

[sotal]

Had a quick play and can't figure anything out!

With the RCL unit disconnected I have 4 wires free to work with. There is 12v, GND and 2 that go to the solenoid.

I tried connecting gnd to the 2 that go to the solenoid - nothing happened
I tried connecting 12v to the 2 that go the solenoid - nothing happened

All still works as before but I'm puzzled - any ideas what the RCL unit would do to the solenoid?

Of course I guess the solenoid could be dead!

[sotal]

OK - more reading up and testing done!

It is a 4 wire reversal system.

It has 12v, GND and 2 wires that go to the solenoid.

You have to connect 12v to one of the wires to the solenoid and GND to the other. This then either locks or unlocks, reverse these wires and it does the other one.

All the other doors work at the same time too!

So now I know how it works I've just got to match it up to a wiring diagram for the alarm!

Got to pop out for half an hour then I'll have a good go!


The solenoid in the drivers door is now proven to work at least!

[sotal]

Phew - figured it out - all up and running - locks and unlocks off the remote. Just got to sort some of the other bits out now.

The alarm just rearms after a few seconds because it hasn't detected an open door. So need to get that side of things sorted too!

[sotal]

For future reference if anyone else finds themselves in the same situation...

The RCL unit plugs into the harnes using a short harness of it's own. I chopped this in half to give me a nice way of plugging it in. There were 4 wires at the RCL unit.

The Blue/Red wire is 12v
The Black wired is GND

The other two are the lock/unlock wires. Connect 12v to one and GND to the other and it will lock or unlock. Switch them round and it does the other.

Using just those 2 wires you can wire it up as a 2 wire solenoid.

My alarm had 6 wires to wire up to it. I wired them all up in the door using the 4 connections that the RCL had used.

Yellow - 12v
Yellow/Black - 12v

Orange - GND
Orange/Black - GND

White - Green
White/Black - Red

That was it. If you purchase one of the cheap RCL kits from ebay for about £8 it could all be wired up in the door straight to those 4 wires - job done in about half an hour providing you have the RCL module in the door.

Hope this helps someone!

You should find a door solenoid then which activates the drivers door lock, its this you want to find, then take the original key fob receiver out and connect the added solenoid to your unit.

Is the driver door card where the receiver for the OE CDL located????
