Technical Wiring remote locking

Hi can anyone help me after checking the wiring I have found out that they are all correct but this still isn't working. I can here the kit clicking but its not locking or unlocking the car.

This is the kit I have: http://m.ebay.com/itm?itemId=271392532823

Can anyone help me?

Hi mate,

The system is NEGATIVE trigger. Dont connect it up for positive trigger of you may do damage to the BCU.

What goes in to the yellow and yellow and black wires is what comes OUT of the white and white and black wire when the lock or un lock button is pressed.

The clicking you hear is the relays closing (making a circuit) when they click, they connect whats coming in the yellow and yellow and black to the white and white black cables.

Ie if you connect the yellow and yellow and black wires to +12v then +12v will come out of the white and white and black wires when lock/ unlock is pressed.

In the NEGATIVE trigger system (such as your punto) the yellow and yellow and black is connected to a good earth, and when the buttons are pressed earth (-) comes out of the white and white and black wires, thus making the doors lock/unlock.

Did you try momentarily connecting a piece of wire between earth and the lock or unlock cable on the cars loom to see if it activates the central locking? As if it DOESNT, then its NOT an issue with the RCL unit, and is a fault with the wiring or the wires you are connecting. That needs to be established first before attempting to connect the RCL unit, as for all intents and purposes, it may be functioning correctly and its purely a problem with where you are connecting into the loom.

Have you got some pictures you can post of -

where and how you are earthing the yellow and yellow and black cables.

and where and how you are connecting the test wire between the lock/ unlock wire and earth?

When you turn your key in the door lock, and all the doors lock, all that is happening is a micro switch is sending a "negative" trigger down the SAME wires that you are splicing into.

Also just to confirm, this is a right hand drive uk punto? and when you turn the key in the drivers side door lock, all the other doors lock?

Hi yes my punto is a UK 3dr, and when I turn the key in the lock on the passenger side it locks and unlocks all the doors, another thing that I was wandering if it could be causing it to not work is that there is a jumper that changes it between electric lock and pneumatic lock (I think I spelled it right) which is shown in the picture of the wiring diagram.

I will take some pictures of the wiring asap

Does it also lock all the doors from the drivers side too?

The jumper varies the amount of time that the "negative trigger" is applied. Pneumatic actuators take longer to close, whereas the electric system you have only requires a quick "blip" of the negative trigger to activate the locking. (hence the time differences on the diagram) your system should work under either condition though.

Hi I'm earthing the cables on a bolt that's on a black piece of metal by the barrel its shown in alot of the guides saying to earth there.

It should be ok, but make sure its clean and bright, ie scratch/ sand off any paint or coating that may be on it and preventing it from making good contact.

As SandB says, on of the steering motor bolts is a good place also, as there is not coating to get in the way of your continuity.

Dont worry mate, we WILL get there

Hi,

Where are your yellow and yellow and black wires earthed?

And when you do the test, hold one end of the wire against that bolt that you currently have your earth to, and touch the other end of the cable to the exposed copper core of the green and white wire and you should hear the doors lock and then unlock.

Ahh ok, thought that was the actual photo, ie as it currently is.

Ok now, no laughing, but i have drawn a diagram to explain the test Im referring to.

RCL_test.jpg

This test will confirm if the problem is with the central locking (unlikely) or the connections, as basically you are taking the RCL kit completely out of the picture.

When you temporarily touch (only needs like 1 second) the end of the cable on the exposed bit of the green and white cable, the doors should lock (and then most likely unlock again as you will probably have the door open)

Hi,

If it works then its a good thing.

We know that the power side if the RCL kit is working as you can hear it clicking when the remote is pressed.

IF the doors lock when you carry out the test, then we know that you have the correct wires and the central locking is working as it should.

The next step would be to connect the white and white and black cables to the green and white and light blue and purple cables instead of the test cable.

RCL2.jpg

You can see from my child like diagram above, all the test lead is doing is bypassing what the RCL kit does.

When you press the LOCK button on the remote, the "lock relay" makes a connection between the yellow cable and the white cable (normally they are not "connected" together) ie the relay holds them apart so no current flows between them)

When you press the unlock button, the "unlock relay" makes a connection between the yellow and black wire and the white and black wire.

The test lead at the bottom of the picture is basically doing the same function, except you are just physically connecting them yourself, rather than relying on a relay to do it for you.

Hope that makes sense.

Alan
