OK, car is safely back at home. I'm going to wait for the harness to get in before trying to revive the SLU.

How long should I keep banging on the SLU before I give up and get the SLU ordered? I'm going to be using a rubber mallet.

actually i'd use a small metal hammer so the impact is hard and sharp to loosen the binded gears inside. just go easy on the taps so you dont deform the housing.

if you have a battery charger, i'd put that on the battery too at 2A or lower while you tap at it and press the start button. max power to steering lock. if u have a battery manager/tender, put it on the car now so you have a good charge.

i'd do the tapping as many times needed until it unlocks. nothing to loose really if it's already broken. you'll have to replace it with a working steering lock anyway to disable the system...unless you want to take it apart.

Yeah, I'm holding off ordering the replacement until I give up on getting the harness to work.

20 minutes worth of tapping/banging on it enough to call it dead?

Hey, quick question.

Before I begin hammering on the SLU, Can I install the harness and leave the brown wire connected or do I have to wait for the car to be in ACC before I disconnect the unit to install the bypass? Part of me thinks it doesn't really matter (just that the brownie is disconnected while the car is in ACC) but figured it would be good to ask.

It doesn't really matter. You can install the harness, retract the lock, and then break the brown wire. Or retract the lock and install the harness with the brown wire broken. As long as the lock is fully retracted when the brown wire is broken, you should be good to go.

Success!!

I did the headstand thing and wedged my 6'5" 265 lbs self up under there and whacked the SLU two dozen times with a hammer. Tried the button several times along the way and then finally heard the most beautiful electric whirl ever. Disconnected the red connectors and she's good to go. Saved $1200 vs the dealer's estimate. Merry Christmas my bank account! BDL is, in fact, the man.

I preemptively cut the brown wire last night.

Own a 2011 Nismo w/ 6k miles, lock was rev. C, car build date of Oct. 2010.

Thanks for all the research into this.

PLEASE HELP!!!! MY car will not start now ! If i cut the brown wire will it start? I have the flashing key, pressing the ignition switch doesn't move from acc to on . The steering is not lock though as i can turn it. Please help im stuck right now!

jumpred the batter thinking its just a dead batter but nothing happens.

removed the posive cable on the battery to reset it , same thing nothing happens so i know i have this steering lock issue also my AT shifter is stuck in park

You have to get the SLU into the the unlocked position before disabling it. Try rapping on the SLU with fist, shoe, hammer, whatever it takes and then see if ignition will go to ACC or ON. Repeat as necessary. Once SLU unlocks, do NOT turn the ignition off until you disable it. DIYs are posted for cutting the wire, installing a harness, and removing the fuse. I've collected a lot links to SLU info at http://www.the370z.com/engine-drivet...heel-lock.html.

my o9 failed last night. never fails 3o* outside stranded in a target parking lot at 6 pm FML!!!!!!not really knowing too many people around here and finally getting a hold of my cousin i had plenty of time roughly 1.5 hrs of researching and finding this thread. 1st we had just removed the slu in the parking lot and pushed it back into position, back at my house in the comfort of my garage we snipped the brown wire. no problems since:tiphat:i love this forum and the great people that share it!!!!!:tup:

Very please to read this and glad I could help.

Belated Merry Christmas wishes to you too and best wishes for the New Year.

I ordered mine!
 

Just ordered/paid for mine.

Received my harness yesterday! Gonna hook it up today!

I need some advice. My steering lock failed. It died while it was disengaged, so i figured i'd just remove the fuse, so i did that.
Now, the thing is that, the car still won't start even after i unplugged the negative terminal from the battery.
I need advice on what to do here to get the car to start.

Any help will be much appreciated, thanks in advance!

Hi Kamus,

I thought I answered this--maybe on another thread.
If you are still stuck, fit battery terminal firmly.
(Windows will fall down on each door closing, so read owners manual first, or re-program. Hold them all the way down for a few secs, then all the way up held for a few secs. Job done after re-setting radio stations.)

Car not starting: Fit that fuse and, if cut, reconnect the wire: then ign on
and start engine. Switch off: then ignition on again, open door but must leave ign on:
remove fuse or cut the brown wire or fit the harness and or the switch: your choice.
