You have seen what I look like, right?

Yep

On a side note, the potential "Egressing DIY" will need a supplement for those who choose not to wear a seat belt. I didn't realize people still do that in 2012 until I notice a thread complete with poll about that very thing on this very forum. Those poor bastards would hit a road block from step one.

this is a question for AXW and KORRUPT...or anyone that actually took apart a broken steering lock. if we were to just remove the spur gear in the pict below, would this mean we would be removing the root cause of the failing steering lock problem?

we wont have steering lock feature as the motor and pinion will just spin inside, but i think it was the spur gear that was jamming that causes this problem in the first place. any thoughts?

where is the detection pads/pins that sends signal back to the BCM? is it part of the large gear or no?

The big white gear seen on the left...

I hope someone with the know how can jump on this project and let us know. Many many reps will be given...

dont try to undermine me kaizen.

Looking the assembly, I believe the 2 blue micro switches, next to the motor, sending the signal to the BCM. The 2 switches are used to detect the position of the white gear.

yah, i think so too.

now are the micro switches mechanically activated by the spur gear? i think so, but i can't see where it would connect in the picts we have.

my RevB still works fine so dont feel like opening it up yet.

Most micro switches are internally mechanical with contact point. The contact point can get sticky from contaminant. The switch nipples are riding on the flat profile surface of the spur gear. I saw someone posting photo by-passing those switches and get the car to start so I think you can permanently short out those switches if you know the switch circuitry.

This part does not look like 500+ dollars part. The motor got powered, then turn and drive the spur gear, spur gear turned the lock column shaft up or down. The 2 micro switches detected spur gear position and then send signal to BCM.

cool. that was the part i wanted to see in more detail.

so you think the oil contaminated the microswitches on the initial GTR recall? could be, huh?

yah, it's probably no more than $35 to make this thing even if it was assembled in the US. service parts have huge margins for the distributor and retailer (dealers).

Should be able to solder bridge the appropriate switch on the backside of the circuit board creating a permanent setting of "unlocked".

i wonder if the "locked" condition is needed for correct shut-down? we dont want the intelligent key icon to show up in the cluster.

Yes the ideal would be to trigger whichever condition it desires based on the pin input signal. The problem is that this would require additional circuitry and always on power (microscopic power drain) to store the current state using a transistor pair. Definitely can be done, and for a lot cheaper than the price of a new lock. If the logic state storage isn't required it will be even simpler, but I haven't had a chance to experiment yet. I guess I will have to buy someone's dead unit since I don't feel like taking apart my working one yet

As a quick fix I think setting it to the always unlocked state would work, but give you the key icon.
