Hi, I'm new to the site but was going to check to see if anyone had any ideas how to fix my problem. I'm rebuilding a 2006 S40 T5 and after removing the battery and unhooking the wires to the ECM to work on the front of the engine it will not start and gives me the Immobilization code. I have put everything back in place and have tried locking and unlocking the doors to reset it with no luck. Does anyone have any other ideas to clear this code so I can get it started again? Thanks.
