Peugeot 206 1.4 pinout diagram

Unread post by Alansking »

Hi

I am trying to get a 2006 206 1.4 Vin VF3**************[VIN obfuscated, can be read by forum staff] up and running again. I seem to now have inherited this car as the owner has decided they dont want to deal with it anymore.

Immobilizer fault on dash no start, following has been done .

BSI reset as per forum, following observations, beeps test shows its seeing the key, I though decided to use a donor system to check so , fitted matching BSI and all related components including ECU and of course chip in key.

Key antenna changed.

Fault persists, wiring loom suspect as somone has burrowed into it before, earth's checked etc.

ECU is Magneti Morelli .

I need a wiring diagram so I can check live feed to ECU or at least a pinout diagram.

Can anyone help?

With the exception of the wiring codes, most of the component codes are indexed here:

Is there any history of the fault? What happened, did it cut out? did it just fail to start one day? Did the fault happen after any work was done to the vehicle?
Can you get comms with the injection ECU?
Are all fuses OK?
Have you checked the CAN lines?

Hi Wheeler

Right so history is a bit all over the place, the car was bought as a low mileage first car for a friends daughter, it seemed from day one to suffer various faults and these were rectified by the car sales folk by charging the new owner, if I had been asked then I'd have said give it back.

The car has had a second hand BSI , BSM and ecu fittednits obvious from breakers coloured paint on the items. These came with a key I am sure as the second key they acquired with the car does not have a chip.

The first time I had any input was with a running fault which turned out being down to plugs and coil pack not been compatible z the coul pack was new but plugs were not correct so those were changed and fault went away.

It then transpired as it foes in most of these cases that the battery went flat through lack of use and the immobilizer kicked in, after charging and reset if BSI car ran.

Owner took it for a drive but it was not clear exactly what he did but I suspect the battery was iffy and he suffered another problem with immobilizer , managed though to get home after which the immobilizer kicked in again.

He then asked me to look, so I checked battery and it was cell down, new battery but would not reset via BSI procedure . Multiple attempts finally saw key been read but immobilizer still active , reading with Snapon I have told me the ECU was down , gives a permanent CAN fault to ECU.

So decided to look at wiring and I found loom has been messed with a bit but i need diagrams now to trace all wiring , i am not getting power to ECU, but I am not sure which wires for this ecu carry power.

What i believe is that the 12v supply is bad. Earths load test well.

To clarify I am a tech but my normal remit is HGV and specialist vehicles ie Blue light.

My actual preference is engine rebuilding but I fully grasp wiring even if its french. My issue here is knowing which wires I should be seeing voltage on at ECU . The fault may be in the car too and I have checked normal suspect areas in peugeot like earth post on sill , behind lights etc , have replaced earth cable from Bat to gearbox to body with new purpose made unit.

What I really need to know is where on ECU I should be seeing 12v supply as I am 99% sure this is a power supply fault .

May be wrong but a pin out on ecu will give me what I need. Particularly for the Magneli Marelli ecu.

Of course I may be totally wrong but looking at loom I think its condition indicates some rather suspect work and I would not be surprised to find a feed down .
