Is there a technical diagram of the immobilizer?
Basically I'm assuming that if the logic strings don't match up between the immobilizer and the key then the immobilizer sends a signal to various parts of the car preventing them from operating. I would like to take my multimeter and test if I'm getting an electrical signal from my immobilizer, (or perhaps even a lack of signal that SHOULD be there) thus preventing the car from starting. The immobilizer is complex, but it's not magic; I should be able to test it myself with a multimeter, I just don't know what or where I need to test on it.
Thank you.
