Citroen Contro unit.

[Eleways]

Hi

I need to replace a control unit on a Citroen C4. So I've got a new one control unit but doesn't work due the immobilizer code.
I've open both central unit but I've found a Flash Eprom M49F4000 and a 93c56 eeprom.
I don't know how replace to fix immobilizer problem.

Anyone can help me?

Thanks!

Luca

Re: Citroen Contro unit.

there is the possibility of cloning
but this is only suitable for experts
bring the control device to a company that repairs such devices that should clone the data then everything works again or bring to Citrön for programming if the used ECUs can flash
