Pin A4 connects to A6 on the "signal transformer anti-drive-off lock". I think that's a small module that bolts on to the steering column.

Hmm... I'll try to trace it tomorrow. Do you have any experience with this diagnosis?

One other thing i noticed... my steering wheel doesn't lock.

So the three problems No steering lock, no start, no frunk/trunk unlock (keyfob opens rear.. using cable to open front)

One thing i noticed is i think the transponder coil is actually working now. it makes an audible click in the dash and in the rear of the car when i turn the key... I do not believe it previously was giving me that much.


I was really tired when I was working on it today, should have put a meter on the battery to make sure it wasn't draining again (there has been some parasitic drain during this.. i'm guessing when the alarm kept chirping)
