I put in the new ECM I recieved. I disconnected the battery to prevent any issues there. I have not tried putting my old ECM back in. My 09 G8 is locked up with "engine immobilized". How is this resolved? The one page instuctions only list the key relearn and stats it will not learn the immobilizer prerelease password or the challenge/response data. It says not to use this as a substitute 10 minute relearn but what is this procedure?
I have a very upset wife and don't know what to do know. I did upload the new VCM and pay 2 credits for this one as well. I have not tried putting the old ECM back in because I would like to resolve this issue and figured I must be missing a step.
Thanks,
