Got information on the switch from this link, http://www.the370z.com/diy-section-d...no-photos.html. The switch is SPDT commonly close, Download Data Sheet: Turquoise stroke switches Data Sheet for: Switch,pin plunger,SPDT,PCB,without boss. Part No ASQ11510J. Manufactured by Panasonic

So much for being a sealed switch, not sealed very well if it allowing grease in.

Ok so the switch must be internally cut, removed or track trace cut since it is normally closed (in the released state).

If the switch removed, it would be normally open, wouldn't it? Then removing the switches would be the same as keeping the switches pressed all the time.

Yes switch removed would be open circuit, which is equivalent to pressing the switch.

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.
Sounds good. But I suppose this is something one must risk doing prior to failure...otherwise same issue with dealing with towing and dealer. Now how many users would risk taking the thing apart while it is still functional is yet another question to consider I suppose. :)

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? :confused:

The big white gear seen on the left...

Kenchan, you can remove the white plastic gear completely and the actual shaft that the gear moves up and down to lock the steering wheel, as well as the motor really. Obviously you wont be able to lock the steering wheel but who cares the car will start. As for the electronic pins I assume they have to be held down and connected for the car to start by completing the circuit.There is a metal plate inside the white plastic gear that presses the pins down and completes the circuit when it releases the steering lock. I am by no means a electronics wizz and if someone can come up with an easier way to do it than a piece of metal and electrical tape then I say sweeet and I will open mine up again and change it.:tup: Hope this made sense.

I just looked at photos of the lock unit internal mechanism. It looks like the 2 switches activated by the column shaft. So the 2 switches will determine if you can start the car or not.

Hope this helps.

Aha, this makes sense. Thanks! :D so how many revolutions does the spur gear make to raise the lock latch and to lower latch/push micro switches? :confused: or does it not make a full rotation? (My guess)

KORRUPT 04-09-2012 08:16 PM
Maybe one rotation. It isn't much.

I bet it wouldn't be hard to come up with a simple jumper module to plug in place of the steer lock and make it like work liked the late 2012 model.

I wouldn't be surprised if they come up with an ECU "upgrade" that allows Consult to disable the steering lock and have it removed. This would be a good feature for UpRev to have as well.

KaienZ34 04-10-2012 06:55 PM
I agree, someone call uprev and get them on it.

kenchan 04-10-2012 06:56 PM
chris- the 'brain' for the steering-lock is the BCM, no? can UpRev, which i believe flashes the ECU EPROM, be able to flash the BCM as well? :confused:

zero 04-10-2012 07:01 PM
Why Nissan used 2 switches to detect the column shaft? The switches got activated at the same time. Is it a redundant system?
