Does the G35 have a black box?

[joe603]

I think it does...but I'm not certain. By black box, I mean a device that records information about airbag deployment, VDC status, speed, temp, etc...

If by black box you mean a shockproof bright orange monitoring computer like in airplanes that displays all critical information leading up to a catastrophic failure or crash or interesting occurence, gets lost into oblivion as the airborne transport vehicle rips itself to shreds following a 522mph collision with the immovable object known as earth, then yes. Sort of. but mostly no. but not a complete no. See the ECM will store diagnostic trouble codes and freeze frame data, that displays all the current readings at the precise micro-milli-nano second that the error occurs. The car's systems operate within certain parameters and when something doesn't operate within its specific comfort zone. The presses stop and the world goes into slow mo as the computer, so to speak, takes a picture of what went wrong at what moment and exposes that weak link for the traitorous swine it is that can no longer be trusted, and must be replaced, fixed, or ignored and that Service Engine Soon light will stay on until the problem is dealt with.

WOW! I'd love to see what you write on RO's. I bet you have the most detailed tech notes on the east coast.

[joe603]

So if you're speeding with the VDC off, and get into an accident that deployed the airbags...could they find out that the VDC was turned off purposefully and not cover you in an accident claim?

I know the new GT-R has a GPS black box that enforces the top speed limiter if your on public roads.

I think the new G's have Black boxes to record ****.

Airbag freeze frame data... If it does display vehicle speed it would be speed when it crashed. And why would you drive with the vdc off? Would you poke a rabid diseased hooker after a 24 hour benji fest without a trojan strapped to your piece? unless you were drifting? And the GTR limiter I believe is only on foreign models, not the US spec. Almost sure of that. Either way, I don't see why insurance wouldn't cover you if you made up a story that the reason you crashed was because you found out that day that the vdc system was faulty and wouldn't turn on, resulting in the ensuing crash. I'm not saying to go with that. I'm just saying things happen. But don't drive with the vdc off. you may "catch" something.

[TeflonG35]

Yeah. Curbs hurt. I can attest to that. VDC probably saved me a few times too. Great device.

Well asking some of the other techs, we believe there is no freeze frame data for airbag deployment, but Infiniti can access, with their advanced computers, data 10 seconds before and after deployment, in case someone wants to sue claiming the air bag went off too late or too early or something silly like that.

I don't know this as fact, however I was told that various data was available after a crash such as vehicle speed, etc. when I purchased my 08. The dealer told me that this came up in a case against the dealer when one was crashed and the claim was that there was a part failure that led up to the crash. Problem was that the driver was recorded at over 100 mph. 10 seconds before the crash. The issue according to the dealer was that at the time of the crash itself the speed was down and it was hard for the cops to show the speed at the time of the crash and this data was requested from the dealer.

So assuming this is true, is peak speed, etc. kept outside of that 10 second or whatever time frame?

VW/Audi can do the same thing. I have been involved in claims where the airbags did not deply, and there was a suite. But VW won. The car was operating as designed, and the accident happened outside of the paramaters to deploy airbags.

I asked because of this thread: http://forums.g35club.org/zerothread/402316

I think they recently started adding some of this technology but i don't think it was available until 2008 models.

I'm pretty sure older G's don't have this data logging.

the accident happened outside of the paramaters to deploy airbags.

I have seen a few offset frontal collisions that one would assume would trigger at least one airbag. Logic inside the unit is a mystery, although I would not be surprised if the feds could unlock some pretty impressive information. The A/B system is not controlled over the CAN network though, it has dedicated circuitry.

[Q45tech]

Air bag and seat belt memory of all ecu/transmission/abs/tc parameters has been available since 1990 on Q45, G20, and J30 as these were introduced into US.

Insurance companies send air bag computer to specialty labs where it is read if there are fatalities or serious injuries.

This usually trips up totalled and rebuilt cars where airbags may not fully work and the system gets jeeped with a non matching air bag computer.
