Steering Lock Elimination

takjak2

Hmmm that BCM 284B1-1EA7D (most recent) on courtesyparts.com is half the price of a new lock. Are they interchangeable? Who thinks we can buy that and pull the plug on our locks? Is there anything else that would have to be changed?

I suppose in theory it's possible that works. The most likely issue is that the ECU (or one of the several other mini-ECUs spread around the car aside from the BCM, there's a lot of them) only wants to talk to certainly models/revs of BCM, in which case you get some nasty DTC and half the stuff on the car doesn't function, if all of the various bits don't match model/version numbers expected. Could be the reverse too: the new BCM refuses to talk to e.g. your old Airbag controller, or your older IPDM, older ECU, etc...

Assuming everything is protocol-compatible and generally works even with "mismatched" revs, you'd still need a cooperating dealership to do the BCM install, because they have to go in via Consult-III and set a bunch of base parameters in the BCM to match the options on your car when they install it.

All in all, I suspect this just isn't something Nissan cares to support, so it's a crapshoot whether it works out or the car goes nuts and wants its old BCM back. Especially with a big jump like a 2012 BCM in a 2009 car. If someone wants to blow the money and dealership install labor to try it out though, it might be interesting

can we just unplug it and jumper some wires together?

Possibly, I'm going to try and figure that out if I can. But the pin-1 cut works well for now.

Has anyone heard from Nissan officially about this? I have talked to two Service Managers at different dealerships in Kansas City. They give me blank look like "WTF are you talking about".

In typical Japanese corporate fashion Nissan doesn't really directly communicate with dealers. I wouldn't expect them to know anything unless they decided to release a service bulletin. Of course this is highly unlikely as they would rather try and keep their problems private (also typical Japanese corporate behavior).

not just japanese, chris. lol. might want to look around a little.

ChrisSlicks

No it's not (and not trying to insult the Japanese people here), but the corporate mentality in Japan is very good at it It's just the corporate mentality, nothing to do with the people themselves.
