The only way you can get this code set in the computer is if the ECM does not see communication from the immobilizer transponder key ECU. Did you get the coil/transponder mechanism around the ignition lock cylinder in place correctly and plugged in? Next you need to make sure that the transponder ECU box is plugged in securely. Unless the wires got damaged between the transponder ECU and the engine control ECM there may be a fault in the transponder ECU. Here in the USA was a technical service bulletin dealing with a problem from 2007 two 2008 in this unit. Do you have the complete vehicle identification number available? I'm trying to locate something that would be similar to the model that we used here in the USA.
Sorry for the delay the time difference is a real pain. I just got online and I will see if I can find a picture of the transponder ECU. Click the links below and save. Let me know if this helps. Keep in mind this is all for left hand drive but it should be the same on the right side just flip flop the location LINK1 LINK2 LINK3
There has to be an issue in the connetor between the two or the transponder ECU is bad.
