Sportsdriver day,plastic cone + GTR = expensive combination

[David.Yu]

This wouldn't matter if it was a simple system to reset, not the £X000 bills that are already making the GT-R a laughing stock...

How come we haven't heard about problems with any other pedestrian safety systems? Or were Nissan the first to market with one on a high performance car?

[Godders]

The idea is; if we hot an object any anything above say +5 miles an hour it might be a pedestrian and so the system fires.

Problem is; Tow bars, Cones, Plastic Bollards, Litter, dustbins blowing around in the wind, Pheasants or peasants (joking). 99% of the time it’s not going to count and the ridiculously stupid price of a reset. Disposable fire once control unit and solenoids is just stupid design. If a solenoid can change a gear at 100th of a second I am sure it can pop a bonnet up and then down again once reset. The design is bonkers.

When the spec is clear I’ll be disabling mine.

[Godders]

BTW; I think the tape will do more damage than the cone... paint's so VERY soft.

Hey Guys

I haven't got myself a GTR yet, but I would imagine once this system is unplugged, its a matter of finding what resistance is expected to replicate these sensors.

The sensors simply send a certain resistance back to the control unit, so if this resistance could be found and resistors fitted in their place it could be solved with no dash lights.

GT-R + internet = massive hype

True, but the massive repair costs aren't hype. I spoke to a performance car insurer yesterday and he said claims for minor front end prangs on GT-Rs were causing quite a few insurers to review their stance on them.

I was as sceptical as anyone else when the first "£11k" story came out and prices were apparently adjusted, but they are still stupidly high.
It's a serious problem Nissan need to sort out IMO.

In the meantime, we need the geniuses at GTC to come up with an aftermarket bypass system urgently!

OK so lets get practical about this. Putting aside for the moment the on the road issue and any legal or political correctness associated with disabling the sensors, it is obviously complete lunacy to leave them connected for any off road event.

So I have had a quick look, and as described there are three sensors mounted just inside the grill.



One in the middle just behind the badge.



And two more on each side towards the edge of the grill.




Each has a plug on it and the loom leads as described to a single plug over by the hinge side of the bonet stay.

So I tried unplugging the plug to all three.



Fired the car up and everything seemed to run fine. Except as expected a warning light, with a nice picture of an exploded bonnet flashes at you.



I plugged back up and the light continued to flash on restarting.

Checked for error codes with the AP and there were none, however doing an ECU reset with the trusty AP put the light out.

So This may be the way forward but I have a few concerns.

First without knowing what is in the sensors or the input circuitry on whatever they feed one cannot be certain about leaving the inputs floating. However I find it very unlikely that the system will trigger without the sensors connected.

Of bigger concern is what happens if you were to hit a "cone" when on track and then connect back up again afterwards? It is possible that the sensors are a one hit wonder and stay in the triggered condition?

So if thats the case then you would need to remove the sensors, which makes this a much more difficult job if you want to disconnect and reconnect for the road, or for a service?

What do others think, and has anyone got any more data on the sensors?


All that said I realy feel that Nissan should provide an "approved" method of disabling for the track?

We need a button :

There is one for VDCoff... they should put one for pedestrian 5k bill.

[TAZZMAXX]

Sorry guys, but I must have my thick head on tonight. How does this POS bonnet pop up system protect pedestrians?

[Philip]

Stops their head hitting the hard engine.

Pops the bonnet away from the engine block so they 'the pedestrian' dont deform the bonnet into the hard surface of the block.

You have to have a minimum distance between block and bonnet, without it you have to have a pop up system.

However the driver may get out afterwards and put this right.

[Jm-Imports]

hit a small animal or rabbit on country road and not good for you..

i disabled mine by just unpplugging them.

and took the hood bulb off.

[Rich-GT]

Still not a lot of fun for the pedestrian.
