Open bonnet warning light on. How do I turn it off.

Hi, I did a wrong hook up of my head unit and since then, even though I have fixed the wiring of the head unit, the open bonnet warning light is still on. I have done an engine light scan and tried to remove this light but no success. I have also disconnected my battery for 20 minutes and then when that did not work I left the battery disconnected overnight but the light is still on when I drive off. It does flicker a little at the start but stays on. 

Can anyone offer an answer? 

Thanks John

Yes, that is the light, a picture of the front of a car with the bonnet up. My car is a 2008 skyline 370GT. 

I have checked the fuses in fuse box by the accelerator, all good there. 

I have checked out the fuses in the little easily accessible fuse box in front of the battery but i haven't gone into the big fuse box under the trim pierces next to the battery. That is my next port of call tomorrow. 

What do you mean by the bonnet pop up component of the SRS. If it is then how do I test that and how do I fix it? 

Thanks John

When you hit a pedestrian, explosive charges pop the rear of the bonnet up to provide more crumple space above the engine to soak up the pedestrian/car energy to reduce injury. These are, obviously, self destructive and need replacing after such a thing.

There are hundreds of posts by V series owners on here whinging about it. Look them up.

Hey John.

 

The following works on my v36.

I've done this many times.. may take a few tries to get it.

 

The procedure to reset Pop-Up Hood manually is:

 

1) Press twice the Start Button (Do not start the Engine, only instrumentation!)

2) wait about 7 sec, the Pop-Up light goes off ---> Press Start Button immediatly (Switch Off)

3) Press twice the Start Button (Do not start the Engine, only instrumentation!)

4) wait about 7 sec, the Pop-Up light goes off, Flashes 3 times, when goes off press Start Button immediatly (Switch Off)

5) Repeat steps 1-2-3-4

6) Press twice the Start Button (Do not start the Engine, only instrumentation!)

7) The Pop-Up light blinks slowly

😎 Turn Off

Hi, with reference to step number two:

The light does not Turn off for more than a milli second and so I cannot kill the ignition fast enough before it comes back.

turn off for more than a milli second and so I cannot kill the ignition fast enough before it comes back but I am killing it as soon as I can.

With subsequent Steps and the light blinking three times it does not actually turn off after that so I am killing the ignition on the third flash. Is this correct?

Does this issue show up in an ODBII error code scan? if so, have you tried clearing the error codes? On my 350GT I had an error that I could clear (temporarily until it occurred again or I had it fixed). When the error was flagged, it turned my VCD off, but clearing the code and restarting the car, temporarily cleared the issue

I had this light on my Q50 when I bought it as the previous owner had unplugged one of the impact sensors for a bit, the above process worked for me, but I had to allow for the time it takes for the system to respond to the start button, so I had to press the button at about the 5sec mark, so the ignition actually turned off at 7sec.  so you had to kind of pre-empt the time it takes for the light to turn off.

otherwise, you may need something like NDSIII or a consult to clear it.  I don't think an OBDII reader will do it, could be wrong though.

On my 350GT, I used NDSII, running on Android, connected to the ECU via a Bluetooth OBDII reader.

Thanks for this. It worked first time for me.

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
