BCM correct. It's a good question, someone will have to ask UpRev if they have any BCM control.

Redundancy yes. Both switches must agree otherwise it's a lock-out state.

So it might be AND logic input to the BCM.

Yes, there are 2 outputs from the steering lock with opposite signal voltages feeding the BCM on pins 97 & 98, so it would actually be A & (!B). I think you could just hardwire to the unlock status and it should work, pin 97 12V, pin 98 GND - you would still get the key signal though but at least it would work and you don't risk burning out the expensive BCM (unless you screw up the wiring).

I tackle electronics from the "end user of the circuit(s)". Maybe you find my new thread "Steering Lock: cut a wire..etc" of interest...learned from all the circuit board connections within the lock itself. Hope it helps.

Crap! Mine just broke! :(

At least my car is in the garage, the steering wheel isn't locked and it's still under warranty. :shakes head:

oh noes, happy. :( hope you get it fixed soon. :tup:

i would call up the dealer and let them know what happened...and if you're up to the task, replace it yourself. they can order you a new part, probably.

Under warranty -happytheman? Versa time, hopefully back up -n running in a couple of days.

happytheman 04-21-2012 07:43 PM

Yah, I'm still under warranty. I'm thinking I might ask my tech about just getting me the part so I can replace it myself, but not so sure how I'd work out the whole loaner bit if I don't take her in? My Z is my DD. :(

I fear that I may be z-less for a week or two. :(

If it is not locked, could you try this?...

I'm a bit skeered to snip wires in my car. :(

I wouldn't touch it, since its covered under warranty.

Out of warranty, then cut away :tup:
