The BIU controls all of the functions you’d expect a body control unit to control, but it is also a key piece of the immobilizer system. If you too are struggling with a Forester immobilizer, maybe this will help.

Here are some of the things I learned about the Subaru body control unit, which they call either the integ. Get comfortable, this is a very long story. As if that weren’t bad enough, our customer was convinced that we “broke” the keyless entry while doing an air conditioning service the day prior. Hooray! It’s always nice when you can take a bad situation and make it worse. Unfortunately the car originally came in for keyless entry not working, but I was able to upgrade the complaint to no-start. I had a bit of a struggle with a Subaru Forester that wouldn’t start. Most people won’t be interested in this page, but it may help a few, so here you go.
