Printer Friendly Forum Posts - 2007 Peugeot 308 Lock Trigger

Hi I have been struggling to install cardot pke system in my Peugeot 308 1.6 hdi year 2007 for few days now. I have managed to install push start button and also pke function by connecting both lock and unlock wires to lock/unlock button wire on main console. The problem is they are both connected to same wire so when I push lock when locked it unlocks it. System has built in option that sends lock signal after minut or so no matter if the veichle is locked or not so when I leave it locks and after some time sends another lock signal which unlocks it so when I return it is unlocked:(
I have inspected wires in main doir and found three which correspond when locking/unlocking. One is 0 when unlocked and -12V when locked (unlock wire I think), the other us 0 when locked and -12V when locked(lock wire). Unlock wire triggers simply by grounding it but I am unable to trigger lock wire no matter hiw I connect it. Maybe it uses double pulse? Please help me any advice is much appreciated. Many thanks

5 wire lock system on the vehicle body control.
You're looking for the motor wires.

As I stated unlock wire triggers simply by grounding it. Lock wire I am unable to trigger. I also found wire that drops when lock/unlock and than right back to -12V. It is the only wire that when I cut central lock doesn't work at all. If I cut one of other two(I think lock) than all locks/unlocks exept main door (I am doing that in main door). I only need to figure out how to trigger lock wire. Thanks

That wire, try cutting it it could be a 1 wire open circuit:-

The problem is no one in the Auto Electrical trade in the UK wants to touch French cars so no info!

The system I've linked to above I've seen in some Peugeots.

Also when I said motor wires, I just remembered there was a separate unlock motor wire for driver door on the 307.

Big problem with Cit/Pug, you can't rely on wiring colours they change them every three months!
The electrics are awful, I've been to dealers for info and they don't know!

I tried cutting (green, purple and blue) and it's a no go. I have probed all wires with multimeter and this is the result.

There are six wires: yellow, purple, blue, brown, green, YELLOW /GREEN.

Multimeter red to +12V, probing with black, lock:
yellow: 12.5-12.3-12.5 (it drops down to 12.3 and right back);
purple: 2.6-12.4;
blue: 12.5-(1.5-8.5)-12.5 (it sometimes drops lower and sometimes higher between 1.5 and 8.5 and than back to 12.5);
brown:12.5-12.0-12.5;
green: 12.5-2.6;
YELLOW /GREEN:12.5-12.4-12.5.

Multimeter red to +12V, probing with black, unlock:
yellow: 12.5-12.3-12.5;
purple: 12.4-2.6;
blue: 12.4-12.1-12.4;
brown: 12.6-(1.5-8.5)—12.6;
green: 2.6-12.5;
YELLOW /GREEN: 12.5-12.4-12.5.

Multimeter black to ground, probing with red, lock:
yellow: 0-0.1-0;
purple: 9.3-0;
blue: 0-(2-11.5)-0;
brown: 0-(0.1-0.3)-0;
green: 0-9.3;
YELLOW /GREEN: 0-0.

Multimeter black to ground, probing with red, unlock:
yellow: 0-0.1-0;
purple: 0-9.3;
blue: 0-0.1-0;
brown: 0-(2-11.5)-0;
green: 9.3-0;
YELLOW /GREEN: 0-0.

I can unlock by simply grounding green wire but am unable to find combination for lock trigger.

Two things, you can only test with the latch at the rear of door thrown over so the car's body control thinks the door is shut.
Much easier to use a test light with an incandescent bulb, Snap-On etc. that will draw the trigger current.
Also you'll get a visual on motor wires.
At rest, motor wires show 0V on actuation 12V+ for 0.8 seconds.
Also better to try from the BCU which is combined with the fuse box.
I think the green needs to be cut.
If the latch wasn't over, you'd never find the lock wire.

My info says lock = YELLOW pin 4, unlock = RED pin 27, white 40 way plug at BCU, doesn't say whether (+) (-) or 5 way.
Test by grounding each in turn if that doesn't work they are motor wires.
I't's quite possible everything in the doors is data.

Front left and right,
Brown 38 way engine fuse box, left, WHITE at pin 8, right, Light GREEN, 6

Rear left and right,
Black 16 way, BCU YELLOW, pin 14, right, Light BLUE, pin 12

Please test, colours probably not correct, always go by pin numbers.

You will of course need diodes, 1N5404 X 4 to split front and rear.

Thank you so very much for all the info. I have located lock and unlock wires at bsi and they were exactly where you said and the same color, thanks again. The problem of triggering lock wire remains.

When I connect my unlock trigger wire (from pke system, it is negative) to main console lock/unlock wire (which is positive and triggering when given negative signal) than my lock wire is being triggered with lock trigger wire (from pke) but with delay - first dome light turns on and than it locks. The problem of that connection is that it doesn't auto lock when distancing from vehicle. When my unlock wire is properly connected to unlock wire on bsi, lock wire doesn‘t work at all. Maybe you have some idea on how to set this up. I have relays and diodes at disposal. I will try to think of a way to do this and post my diagram here - I believe I have to send reverse polarity signals simultaneously to both lock and unlock wires: - to lock wire, +to unlock wire when locking and unlocking is easy - just - to unlock..

-------------
DK

Also I have just ordered diodes you advised me to on ebay so I guess by the time they get here I will learn about connecting them:)

-------------
DK

Ok here is what I will try tomorrow. Do you think it will work? Thanks posted_image

-------------
DK

Shouldn't need it,that's a float at rest system, only ever used in 2 vehicles, GM SUV and passenger doors on London Taxis.
Use a bulb test light, doors shut and apply ground to each wire through the test light. If that doesn't work, use your meter, lock and unlock, black probe to ground, red probe to each wire in turn set meter 20VDC if you get 12 Volts in each direction for just under a second they're motor wires. Last test, at rest, meter red probe to a good constant 12V+. Black probe to each wire in turn if you get 12 V+ each time then it's a 5 wire system as per your original diagram.
Let me know what happens.

This diagram doesnt make sense to me because when in unlocked position, lock wire is +12V so +12V trigger to motor end wouldnt make difference..

On the other hand, this one is what I would think should work. It is basically same as mine only it uses another two relays for unlocking.

The only thing that bothers me is that, in description it says that both motor legs are open.

I will test tomorrow and post results. Greets

Ok I have figured out how to trigger lock wire. It triggers by cutting unlock wire and than grounding it(sending negative signal from pke lock wire). Unlock triggers by grounding bsi end of unlock wire. The problem with that connection is that when opening door it auto locks so there is a problem of leaving the key in the car. Also it messes up dome light cause it auto shuts down when opening door. So I tried connecting relay which disconnects unlock wire when locking car. For some reason positive end of relay bothers lock signal so it doesn't work. Than I used steering light signal(which is positive) to disconect unlock wire when locking. And it seemed to work. Car locked when moved away and unlocked when approached; also, blinkers worked as well(sometimes, sometimes not) But, for some reason, when I press lock on remote it locks and right away unlocks. I could live with that since when I press unlock signal it auto locks after few seconds. But when I start engine, shut it down and move away it does lock/unlock thing (sometimes it doesn't but mostly does). I am busting my brains out trying to figure it out. Also, I believe I have wrongly connected trigger door wire - I connected it to one of dome light wires(dome is with delayed light) which is always positive - originally I connected it to dome light wire which is 0 when light off and +12 when on but that was making clicking sound from pke unit with light off...
Any ideas?

-------------
DK

Yes go to one of the door triggers as explained above NOT dome light.

And the locks are the one wire system I told you about at the start.
And that's the problem, you can't assume anything about them, completely illogical, I've had wires change colour halfway through the loom, a van where the cargo area was controlled by the driver door switch with none on the back doors.

Do you suggest I ground lock wire and connect unlock wire as on this diagram?

Ok will let you know how it goes. Maybe it will work without connecting proper door trigger wires. Trigger wire on pke is fine when on +12v, when on ground pke unit is clicking, I guess proper wire would be ground when doors opened and otherwise +12v.

Yes that's the norm for 98% of vehicles.

It doesn't work. It does lock/unlock when locking. It only locks properly when you ground lock wire AFTER opening unlock wire. If ground is present before it than it does lock/unlock(in same second). posted_image

-------------
DK

Ok I have managed to solve it. I connected unlock wire as on diagram above. I used a relay to switch steering light pke signal from + to minus and connected it to trigger lock wire. Now it is working flawlessly😀😀.
Now I will continue on connecting steering lights. Can I use only one pke wire to trigger them all since my other is used as described above. The idea is to connect them(4 of them) through diode to positive pke trigger?

-------------
DK

Yes, but relay it with 4 X 3 amp diodes (1N5404).

Can I use other diodes or must it be those?

-------------

You need 3 amp diodes for the indicators, 1 amp will blow 1N5404 is the most common, they are all the same price but 1N5401 up will do.

Just one more question. Will it conflict with current position lights setup, because sometimes they blink when I lock/unlock and sometimes they dont? Thanks

That's why you need the diodes.

Again, test that's why I said it's a Peugeot, follow the wires back from the bulbs!
Those diodes are zeners, totally wrong.

I used zeners to connwct lock and unlock signal from pke. Is that ok?

-------------
DK

I consulted manual and I have two options. I can connect to two wires one of which controls both left side lights and other both right side lights. Also I can connect to 4 wires which control them separately. Is it all the same or should I go by 4 wires connect as you suggested (2 wires connect is obviously easier)?

4 separate with the diodes.

Maybe it can be turned off via computer software connected through obd2 interface?

It seems that I should delay lock trigger signal for few miliseconds. The lock/unlock thing happened to me once in this two days (like once in a hundred or so). Maybe I can use a capacitor for it. I am not that skilled in electronics so I ask for your advice. Thanks

-------------
DK

Or maybe just couple of meters of cable?

-------------
DK

A diode and an electrolytic cap should do the trick.

Can you change lock time on your unit?
It's actually a Peugeot fault because of bad build quality, one of the actuator micro switches is out of alignment.

Hi Tarafelli,

I am installing a pke system myself, iv got the remote/button start installed I just need to sort the central locking, any advice would be greatly appreciated

Sure, you have it a lot covered here.
You will have to use relays so I hope you are familiar with it.
Firstly, you have to locate lock and unlock wires (see previous posts).
Than: to unlock the car, unlock wire should be grounded;
to lock the car, unlock wire should be opened and lock wire grounded (or vice versa, not sure anymore, do check it).
So, you should connect negative signal unlock pke wire to car unlock wire and connect car unlock wire and pke lock wire to relay so that negative signal lock pke wire opens it. Than, through another relay, reverse polarity of one of your blinker wires (there should be two and with positive polarity, if they are negative, than no relay for reversing polarity is necessary), and connect it to lock wire (because blinker wires trigger in the same time as lock/unlock pke wires). The other blinkers wire should be connected to 4 blinkers via relay and diodes as instructed above by Howie II.

Hope it helps, I have detailed instructions written somewhere but have to look 4 it.

Please, if necessary do state the type of your pke system (attach few photos of it and its diagram and so on) and I will get back 2 u when I can.
Greets

PS
My system works flawlessly since the day I installed it and am very happy with it.

-------------
DK

for the pke system I have a 300ma 12v output for the unlock wire and a 300ma 12v output for the lock wire.

So on basic cars id just connect them to the main actuator in the drivers door and boom but on this model I understand its reverse polarity.

I have a spdt relay and several 1a 3a and 6a diodes at my disposal.

I am trying to locate the atual lock and unlock wires at the minute if you can help ?

sorry disregard the previous!!!!!

for the pke system I have a 2 outputs, 1 for lock, 1 for unlock and which ever you press goes to ground.

Put me out of my misery and look at the lock/unlock single wire open circuit lock part of the relay section on this site.
PS connect your PKE outputs directly to the door motor wires and boom is about the right word as your PKE gives it's impression of the Great Fire of London.

iv got the lock system done! connected directly to EH1 in the fuse box compartment this also folds my door mirrors in perfectly as they key does.

Iv also got the unlock wire connected which works however it doesnt open my door mirrors which is slightly annoying so im looking into that now.

Does your welcome lighting still work on your car?

Everything is working flawlessly in my car.

But you obviously have newer model so I wouldn't know how to help you with those features..

-------------
DK

mine is the 2008 model, se 1.6 sport.

I cant find the correct unlock wire on the 40pin bsi unit.

Iv found the door triggers but pin 27 says its the unlock wire as well as the door trigger which is confusing, but no matter what I do I cant get my mirrors to open which if they dont open neither does the welcome lighting.

Which pin did you connect your final unlock wire to?

lock = YELLOW pin 4, unlock = RED pin 27, white 40 way plug at BCU

yes it does say that it is both unlock and trigger which it is..

the way I solved it is that I took one of the wires from dome lights for the door trigger wire.
but I had to connect relay on it through lock pke wire to change its polarity upon locking or otherwise the alarm would go of.
that part (trigger wire) is essential for pke feature to work...

I believe it was like: it should be negative for pke to work which it is when the car motor is running or the car is unlocked with doors closed and when locked with motor off it becomes positive; or it was the other way around

-------------
DK

No matter what I do I cant get it to unlock and my mirrors and welcome lighting to come on. not happening :(

it locks perfectly, also the remote start for some reason it wont work, iv got to get in the car press the brake pedal and then it works - confused.com

if I could sort these id be chuffed!
