ecitreon c3 ecu locked

[tonyboy101]

hi all

i have citreon c3 diesel in today for brake pads customer asked if i could check why enginemanagement light on as she had already had to another garage and they fit new temp sensor
i connected snap on solus code was for temp sensor open or short to ground so i cleared codes and car would not start

i got my lexia out and this says ecu locked and no keys programed it also had some other codes in modules [ i will add them tomorrow]

can someone explain to me how to unlock ecu and program keys please with lexia and do i need any codes

many thanks tony

I think you need PIN code for programming new ( lost) keys. Post VIN, I get PIN for you

Hi Tony,

Why did you use the Snap-On Solus in first place when you have the Dealer Tool LEXIA 3............And causing all the problems........

[darguewin]

erasing codes will not make a car loose all its memory unless in the snap on code reader you had the wrong key in the lead and dammaged the ecu. as for coding the keys. lexia will give you a step by step guide on coding keys as you doing it. you cant go wrong.
good luck

Right, use Lexia and will start!

Hi

I have seen people using Lunch Tool on Nissan to erase fault codes on Airbag Module and end up having Immobiliser Fault on that car.

So nothing is impossible I personally prefer to use the dealer tool for the Vehicle i am working on it, for the rite Diagnoses (if you have the dealer tool)

Hi

Have you tried to Reset the Battery and see if that helps...........

[Albanais]

Normally when you have this kind of problems the cue is that bsi does not recognize the key any more. This is classic to old c3 and peugeot 206. So to resume either you try to start the engine with the second key if the lad has one, either you try to learn the keys. If you do not succeed with learning then you have to do an immo off in order to start the engine. Did you drop the key down accidentally while checking the car? If yes second key is needed for sure.
Hope it was helpful

did you have any luck with it? if ecu is saying locked normaly leaving the car with ig on for about a hour will unlock it.
if its lost it imoblizer code it may of lost other info in bsi as well so you will be best to check the programing.
also make sure all of the fuses are ok,

Hi

probably you lost earth or +12v on ecu, so check all supply,
if that ok then check CAN lines from ecu to BSI
