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.

thaks for sharing the dreaded thing that may happen to myself

Crap! Mine just broke!

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

Boo!

kenchan · 04-21-2012, 05:06 PM

oh noes, happy.

hope you get it fixed soon.

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, 08:43 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?...

Steering Lock: cut one wire. /switch optional

happytheman · 04-21-2012, 10:55 PM

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
