Seriously. That's what happened to me. Caused all sorts of rear damage.

Oh, and btw, I swear the car started faster with the fuse pulled. Zero delay when I pressed the start button.

Mine seemed faster as well.

Not a single delay or problem since doing this. I've started and stopped and driven the car a lot over the past 2-3 days now. Absolutely no difference in the time it takes to fire up.

I'm really glad you guys are do good with this,the guys on the other thread should be reading this.
Me and Dai talked about this for a while plus I checked the wiring diagrams and I knew this would work mainly b/c of the ECU's ability to learn and adjust as it sees fit.

There's no way the ecu is "learning" here.


I doubt Nissan invested the man-hours necessary to adapt to things like this when something like an automatic timeout would do (which is already a native function in CANBUS)

Even just having a flipped bit for "check steering lock y/n" makes no sense, and certaint doesn't appear to be there.

Also worth keeping in mind that the "learning" being referred to is a very loose use of the term.

When it "learns" to set fuel trims, it's just looking up values in a table...you'd need to have predefined behaviors for "steering lock removed" that are stored in nonvolatile memory...and then account for what happens if it is reinstalled. Checking every time it is started accounts for that.

The ecu doesn't actually do any learning, which is an important distinction.



Oh, you're talking about draining volts? I see now.

Beautiful! Glad to see there's finally a "fix".

Indeed. It feels so great knowing that my car will start every time I step foot into it. Before, I felt like it was a game of Russian roulette. I had a Rev-C (post 6/10 build) and can't imagine how nervous the A and B guys felt. LOL!

KingZee

Mine still delays from time to time...hardly noticeable though at this point, I'm pretty used to it...I'm actually pretty surprised some people never have this issue. Good to hear I guess

Why don't you try to reset your ECU disconnect the - of the battery then hold the horn and the brake pedal down to drain the rest of the remaining volts reconnect and it will relearn as you drive,idle,etc..

Happened to me this morning.

No offense intended, but the ECU has no magical ability to "relearn" anything except for the specific things that the Nissan engineers programmed it for - and I really doubt that the ECU has been programmed to "relearn" anything having to do with the steering wheel lock. Besides, as others have noted, this is a very minor thing that happens once in a while.

Baer383

And you have read the wiring diagrams,talk to techs, and determined on your own that the ECU can't relearn,

No, I never said that the ECU can't relearn - I said that it is highly doubtful that the ECU firmware engineers programmed the ECU to "learn" (or "relearn") anything about the steering wheel lock in particular. Now, that's certainly just my "opinion", but it's based on almost 40 years of experience being a software/firmware engineer and writing a boatload of control software.

But, you certainly might be right.

wheee!

Just a small warning to people:

Another member had an issue this week with the Power Distribution box unrelated to this mod. MAKE SURE the seal is good when you close up the fuse box after removing the steering lock fuse. His had a bad seal and was not watertight and all the water coming off the windshield drains past this fuse box area. His got wet and the resulting damage was extensive. Fried ECU, fried/melted fuse box. All was covered under warranty because of the defective seal, but I want to ensure people closed that box properly and snapped it shut tight. The repair bill was close to $7000 for the dealer, not including the $400 towing bill....
