Hello everyone. I accidentally made a voltage drop in the car, the battery ran out. I know the problem with PCM and so on. But now something strange is happening. My keys are not missing, the car starts, everything works except the central lock of the car. I tried to configure the PCM as available, it is successful. But the Security - Immobilization function gives the error “Failed to write the target identifier" in the second stage.

@sandmaennle do you do remote repairs? a lot more involved that way,and a lot more time getting it all to work.
starting configuring body control module (bcm) as new is solved my problem :|
but I had to pay $50 for it, so I'm surprised I didn't try it myself

hope it helps someone!!! I got off easy, I was about to remove the pcm & bcm & bcmb and send it in for reflashing....

Hi @sproot ,
sorry for my delay. It was Jaguarandi with the 50$ repair. Not me. Today I fix most of the programming issues myself. And no, I don't do remote repairs any more. Done it 2 times. Horrible. There are always things the drivers on site don't pay attention to. And it took me so much longer. The second time I didn't succeed programming the KVM+keys remotely after 2 hours. Drove 2 hours to the dead cat and programmed KVM+keys + BCM and updated BCMB with 30 min. Root cause was simply read the SDD message and follow the instruction during the key programming. If it says the second time push the unlock button, just do it :) . And only once. Not twice.
And today I know how difficult it was for MoJo two years ago to do this key reprogramming remotely :)

Cheers
Dirk
