Central Locking Not working

[Ryan]

HI everyone!

I new to this kind of thing, so please be patient with me.

I have a problem with a 206 cc Y Reg (2001)

The key fob wont work. it doesn't lock or unlock remotely.

When i use the key to open either door manually it only unlocks that door and doesn't open anything else. I cant hear the central locking system working at all.

However,

When inside the car and the key is in the ignition, if i press the lock button down on the door, it locks both doors and you can clearly hear the central locking system activating. same again to pull up the lock on the door. central locking kicks in and unlocks both doors.

But when I Take the key out, climb out of the car and shut the door, and try to lock the doors remotely nothing happens..I can only lock the doors manually! and same as before, it only locks that door the key is in and I have to go around and lock the other door manually.

the central locking only seems to work when the key is in the ignition and manually pulling or pushing the lock on the door.

Ive checked all the fuses inside the car under the dash with a multi meter, all seems ok. I'm not entirely sure which fuse is which.

Is it possible that with the key in ignition and switched on (not turning engine over) that the central locking has power and works ok manually pressing the button up or down. and that when the key is out, the remote central locking then uses a different circuit that doesn't have a fuse in it maybe?

I can understand the key maybe an issue, either not working, not programmed or what ever, but the central locking not working when manually using the key in the door! seems a little odd to me.

Its a two button fob if that's any help.

Getting the right owners manual would be a start, cant seem to marry up the fuse board diagram correctly, one online PDF states number 16 others state fuse E!

I'm scratching my head!

Any ideas would be great guys.

You can download the manual from our site.
I think you may have a twofold issue. Firstly the fob. Have you tried a new battery or I think it shows you how to reset fob to car in the manual?
Secondly there are switches in the lock mech that close when you turn the key, and I think you may have an issue there.

Hi there, Thanks for the reply.

Yeah, i have tried changing the fob battery, and tried several times to reprogram the fob...to no avail.

I think you might be on to something when you mention the mech inside the doors....but it would have to be both doors wouldn't it? like I said, they both unlock at the same time via central locking mech when the key is in the ignition and you lock or unlock it manually from inside the car.

whats strange is that which ever door I choose to try and lock/unlock from the outside (Manually using the key) the central locking just doesn't work.

I will open up the doors and have a good look round inside to see if there's anything obvious. loose wire or what ever.

Ill let you know what i find.

Thanks again for the help.

Sorry, forgot to ask. Do you have a link for the manual?

Ok, managed to get round to looking at the doors. nothing seems out of the ordinary. the mech seems to work fine. so I tested it by putting the key in the ignition, pressing down the lock button on the door, the mech works fine, locking both doors and unlocking both when i pull the lock back up. take the key out of the ignition and the mech works as it did before, just no central locking. almost seems like there is no power to it when the keys out.

I couldn't locate the fuse correctly on the link you gave me. however, i did find another handbook


this seem to correspond to my fuse box. its saying fuse E. and it was. i pulled the fuse and it stopped working. replaced fuse, same result as before.

so nothing wrong with the fuse as far as i can tell.

does the CL system have it own brain? could this be a programming issue?

[Ryan]

I have a possible theory! Iv'e just changed the bulbs in the "multi functional display" unit, and it now works ok.....the thing is, every time I set the clock, temp, etc....then turn off the ignition and remove the key, everything resets back to 00:00 when i put the key back in.....this sound to much of a coincidence to me. anyone know anything about electronics?

[Ryan]

could this be a shunt fuse issue? i just cant seem to find a fuse diagram that matches my fuse box.

Beyond me , I'm not an electrics man. However, as a layman it sounds as if a permanent live feed is no longer permanent for whatever reason.

Over to the experts....

[Ryan]

Thanks for having a crack anyway mate. I think job 1 is finding a the correct fuse board manual! I just cant seem to locate one that fits my car. the one Col gave me a link to wasn't the correct fuse board.

[Capncol]

There are 2 fuses for the MFD & 2 for the BSI. Have you checked all 4?

[Ryan]

The problem i'm having is knowing which fuse is which.... this is why I'm trying to find a fuse board diagram.... the closest i can find is in the link below.. (add the www at beginning, it wont let me post links)

homepage.ntlworld *DOTCOM* /steven.tr ... ndbook.pdf

when I marry up my board with the one shown, it makes things worse. so this cannot be the correct diagram...

If I had the diagram, I could reset the board. assuming its incorrect

I just cant find a diagram anywhere. not even on Peugeot website.

I've checked all the fuses and they all work. the panel under the steering wheel and the one under the bonnet.

I know I keep going back to it, but its like there is no power once the ignition is switched off.

central locking doesn't work at all. with key in door or with Fob.

Radio cannot be switch on (with key out)

clock (MFD) resets everytime the key is taken out.

mileometer resets too.

there all acting like the battery is off.

I saw in one of your other threads from someone having the same problem, he, after a while, noticed the "Shunt" fuse was in line instead of being one step up.

I have a shunt fuse in no1 slot and there is room for another, labeled "HS" (Shunt) between 5 and 6. however, this seems like a wider fuse as the shunt from slot 1 wont fit in there.

could it be a shunt fuse issue? not getting power to auxiliary's i,e CL MFD CLOCK..etc


I do appreciate your help guys

Thanks

I can't get your link working. I'm away for the weekend, and if you are not sorted by Mon, I will see what I have.

Check your ignition to bsi lead, its a loom consisting of 4 thick wires going into the bsi from the ignition switch, it will have a black plug.

Have had a similar issue on my car with no +ve diagnosed on the multi function display despite it working ok and various other electrical faults and on top of that discovered that this small loom had been yanked out of the bsi (I presume while hunting for a cure to other faults) and the clip that holds it in had snapped off allowing the plug to move in and out (ooer) with road vibration and disconnecting the supply.

Sounds like a good area to start.

Hi Slo,

thanks for the tip. thought it was a certainty when you mentioned it. but sadly no. all looks fine. i'm going to try and find a SHUNT fuse from somewhere. its the grey and green one between fuse 1 (which is also a shunt) and 6 off set.

Well , I'm assuming this is the problem, still cant locate a fuse board diagram. if you google "206 cc fuse board" and click (images) pictures 11 and 17 are a match for my board layout. I have the SHUNT fuse in location 1, as does the one in the pictures. but i need to locate the green and grey one. which happens to be a different size, width wise. from the red and grey one. I have a 5 amp fuse placed in line. I'm guessing this needs to be a SH fuse off set so to shunt power to the offline gizmos.

finding a shunt fuse seems to be just a difficult to locate as the bloody fuse board diagram! lol.

ill let you know how I get on.

again, I do appreciate your help on this guys.
