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

[John Stafford]

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

Is your bonnet open?

Most likely a fuse blew with the wiring issue (no detail supplied, so an educated guess), suggest checking them all first.

What car?  is it possibly the bonnet pop up component of the SRS system?

does the warning light look like this?

 

[John Stafford]

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?

[John Stafford]

You are a genius. Thanks heaps I finally got it. Cheers John

[DashyyPC]

No worries mate.

Glad I could help haha.

Hi Guys

I try to do the steps may be I'm bumb didn't get it. Anyone got got a video of this process

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.
