It is a known, well documented issue with 2009-2012 models (some 2013's as well) which is why Nissan eventually stopped using the ESCL entirely.

Lots of luck to you.

 

Thanks again. I just hope that I am diagnosing this correctly. Infiniti shows 2 parts

Steering Lock - Infiniti (48700-JK000) $672

and

Steering Lock - Infiniti (DHGMM-1NC1A) also $672

To ask a stupid question, what if I try to bump the started solenoid to get it to start that way to get it home?

 

No. That will just physically turn the engine over. It will not allow the engine to run. The ESCL module does more than just physically lock the steering wheel.

When attempting a engine start: the ESCL module sends a "unlock" signal to the BCM which in turn transmits a signal to the IPDM/er (fuse box next to battery). When all of these signals are in "agreement" the ignition sequence begins and the engine starts. Any signal out of place and the result is "no go." No fuel, no ignition, nothing.

Being that the steering wheel is not locking, likely your ESCL got stuck. I would try the methods listed above- in warmer temps- and see if you can get it to cooperate "one more time-" long enough to get the engine running and cut that damn wire! lol

The way I understand it- and I am not 100% sure on this (others can correct me if I am wrong), but I believe there are two (2) different types of the ESCL module. One, the 48700, physically locks the steering wheel just like your OEM unit while the DHGMM module does not (it just offers a second layer of iKey/ Immobilizer verification). I would suggest you check out discountinfinitiparts.com and plug in your VIN. That will give you the correct p/n for your specific car. You can also email them and ask for help- they are the best (IMO).

 

Yeah, I didn't think that would work. They show 2 parts also for $660 Ea. 48700-JK000 & DHGMM-1NC1A I'll call my local dealer tomorrow to clarify.
Thanks again!

 

For a while, as part of the Nissan recall for this issue (since expired) there was a "quick fix" box that Nissan sold to "bypass" this issue. The OEM Nissan original part number was 48708-9N00A for around $50. Now I found some similar parts on eBay- all around $50 or so. Again, this just handled the electronics- it did not physically lock the column. You may want to look into those as well.

 

Its funny that you say that, I saw some on eBay too, ESCL emulator, if Nissan sells it I'll go down there and get it, Nissan dealer 20 miles, Infiniti is 50. Looks like I can just move the connector and zip tie it up there.

 

I contacted 3 of the eBay sellers selling the emulator, I gave them my part # and said not a match. I removed the plastic pieces below the steering wheel and found that this is the part I need.
DHGMM-1NC1A. https://www.ebay.com/itm/25534125130...QAAOSwa7FhuBfC
I tried tapping with a hammer and it didn't help, now it only cycles between ACC and ON, when I go to lock the doors, I don't see it go to LOCK. Steering wheel still moves freely.
So I'm either going to buy a used one and if it works, pull off the connector and cut the brown wire. I'm going to ask one of the Ebay sellers of the emulator if I can try it and if it doesn't work can I return it. Probably going to have it flatbeded to my house.

I saw this solution to a fix on youtube that I never saw before, but my module looks a lot different.

 

The 48708-9N00A part number I gave you for the ESCB (Electronic Steering Column (Lock) Bypass) module was from the Nissan recall bulletins that were issued for the 370Z, Altima, Maxima, even the $100K GT-R. Basically any 2009-2010 model that had the electronic lock/ Push-to-Start feature. Nissan ESCL Recall. As is par for the course, Infiniti did not specifically address this issue... like they do for all other issues they ignore it and the customer.

If the emulator works for the 370Z, it should work for the G37- they are practically identical in most ways especially in the electronics. It does NOT work on the G37's. Different system configuration.

Either way, you know what the problem is, it is just a matter of getting either part and going from there.

The video is pretty spot on. Though the actual module will vary in "looks" depending on the different types of steering columns there are, the function on the ESCL is the same. If you will be doing the work yourself, I would remove the old module and give it a shot. What do you have to lose?

Good luck to you.

 

Got if fixed last week! I was getting ready to have it flatbeded to my house. Went there and it was warmer (mid 30s). Put the car on the charger, I had the lower dash pieces under the steering wheel removed, removed all the components. hood release, key fob holder, switches, etc. so I could get in there and remove the ESCL because I found a used one for $120. 2- 10mm bolts were on the top, can't see them and there's only like 1.5" clearance, was able to get a 1/4" drive ratchet in there and started getting the first bolt out. Took a break, reconnected the battery then realized it was now stuck in Park. I had removed the connector from the ESCL the day before so maybe that had something to do with it. Connected that and I cycled through all the ignition steps, I noticed the yellow key was not illuminated and hear a noise I hadn't before. Pressed the brake and to my amazement it started. Drove it home with everything dangling and all the tools on the floor. Shut it off, put it in ACC, removed the ESCL connector, cut back the black plastic 2", cut the Brown wire on Pin 1 2" back from the connector. Tapped it up, put everything back, no steering lock now. Driving it every day now, no issues.

THANK YOU EVERYONE!, Especially ILM-NC G37S

 

I am glad that you got her up and running and were finally able to cut that wire. You will not have to ever worry about that damn module ever again!

Thanks for the update.

 

I sold the car a little while ago. The guy called me today and it won't start now. Cycles through LOCK ACC ON. Won't start, he says the steering stays in the locked position. After I had cut the brown wire the steering never locked while I had it. Any ideas on this, I'd like to help him. There is no yellow or red key on in the display. I don't understand how the steering is locked now.

 

Have the new owner check the brake switch (there may be 2). Won't start if it doesn't think your foot is on the brake.

 

I will, but with the steering lock stuck locked, even if he gets it started, he can't drive it.

 

i have a g35x 2007 with those symptoms steering wheel is locked and it wont cycle through all position anyone know what it could be?

 

I have pulled out the fuse under no crank situation, what can I do now?
