Unfortunately, I don't know about the immobilizer thing. I have only driven the car one time (about 3 miles). I discovered a brake problem when I got it home and haven't driven it since. I'm spending 6 weeks getting everything put back to rights before driving it. This poor thing is a solid car that's had an idiot mess with it, so it's a matter of tearing all the garbage work out and doing it right.
I looked up the CDL diagram thinking this might be part of that (locks don't work right), but it didn't look like it. I'll research the immobilizer. Thanks.
