Impact detected
 

Impact detected - OnStar was called automatically (sp?) and I was just out 4x4 wheeling in some dirt just to the left of the road when this went off - minus the airbag, thank god/gods/deitiesd (sp?)

WTF? secound gear and having some fun till this?:rant: :twak: Has this happened to anybody else?:lame:

Re: Impact detected
 

WTF? I'm I the only that has seen this error? (pad):popcorn:

Re: Impact detected
 

REMEMBER ...

its 3:10 AM on the east coast

Most people sleep except old men up peeing !!!

Re: Impact detected
 

This old man is at work...

Haven't had the onstar thing happen to me yet.

Re: Impact detected
 

There must be a way to disable the onstar/ impact detectionwhen off roading? Probably not, but it would be nice to know if there was.

Re: Impact detected
 

This is sure to be a hot thread, It does seem that there should be a way to bypass it while offroading. What did On-Star say about it?

Re: Impact detected
 

Hell.. I nailed a deer at 45mph.. Beat the front end up, slid up the hood and nearly came through the windshield and the bastiches never called me..

Re: Impact detected
 

What?? wtf? So where is the deer?? at home in the freezer I hope.
But thats crazy how nothing went off, have you spoken to your dealer about it?

Re: Impact detected
 

They wanted to know if I was all right and if I had been in an accident. Was a little pissed off at that call, had the radio turned to a good song. Told them that I was out bombing round in my Hummer and having a good time.

Re: Impact detected
 

That is F@cked up. How do those deer steaks taste?

Re: Impact detected
 

I would recommend you take the vehicle to the dealer and have them troubleshoot the problem.
The way the system works, the SDM should not have signaled the Onstar module to call unless there was an actually deployment of the air bags.
If there was a signal sent to the onstar module, there should be a code in the system that the dealer can read. Then again, your SIR light should have come on too. So, it sounds like something is wrong in the system somewhere.

As for the person who hit the deer, be glad your bags did not go off. Frontal bags are designed to be deployed based on deceleration not impact. That sensor(s) up front is used by the SDM to determine what stage of air bag deployement should be exercised; stage one or stage two. Stage one being less of a force than stage two.
Hitting a deer is not a sudden deceleration, as hitting another vehicle or a brick wall. After hitting a deer the vehicle moves forward and does not decelerate rapidly.

freak deal

Re: Impact detected
 

Semi off topic....its nice to have a switch to turn off the power to onstar or the GPS.....just so you can drop yourself off onstar radar if needed.

What if, like one of those action movies, u needed to disapear from the authories for a while until you found the real guy who did it. LOL. Personally,I just dont like the idea of some agency being able to locate me at any time.

Re: Impact detected
 

Damn skippy..!!! 4000lb truck vs 130lb deer.. I don't even recall feeling it bump that much.. Just a lotta noise and cussin'..

Had to call my wife at home to get a phone number for the sherrif.. Was nervous enough I couldn't even keep the number in my head long enough to dial it, so I had her call them with my location, phone number and stuff... They called me back and then found out I wasn't in the county by one block and I needed city police so they tried to give me ANOTHER number to call and remember.. Ended up with them calling the city police and having them call me back again.. After I settled down a bit I realized I could just hit that blasted Onstar button and had them call whoever it was I needed.. Hell I mighta been able to work out a commercial spot with 'em..

Was thinking there's no need to worry much the bags going off because the seatbelts weren't on, but I've got buckles "clicked" to keep the chimes from pesterin' me so I prolly woulda had a nasty headache if it'd been something more sturdy like an armadillo

Wasn't much left of the deer.. Grill and hood busted the hams up and the windshield took care of mutilating the shoulders...

Anyone ever hit the OnStar button just cause you were bored and wanted someone to talk to..?? Anyone ever got a date that way..??

a little paranoid, arent we?;)

Re: Impact detected
 

Onstar has NO air bag impact sensors. Those sensors are for the sensing and diagnostic module (SDM). It is the SDM that signals via the class 2 circuit that the bags have been deployed. Technically, the signal goes through the BCM, the master, but it essentially comes from the SDM to the Onstar module.
a
As for air bag sensors, there are two in the front, two in the side and a roll over sensor (if equipped with side air curtains), seat sensor (presense and position) and the SDM.
For a frontal collison, primarily the SDM detects a repaid deceleration, and then determines what force to blow the bags depending on the front sensors. If no one is in the passenger seat it will not blow the passenger bag. For side collisions the sensors signal the SDM to blow the side bags, but the front bags may not blow.
The SDM used on this vehicle is primarily the same used for years, even for those that had NO frontal sensors.
There are NO sensors in the rear. The signal to Onstar may tell them front bags, side bags or all, but that is about all the info the module can send.

HAHAHA!

Re: Impact detected
 

I think we may be talking about two different things. After I posted I double checked an on-star pamphlet - It was not a Hummer specific brochure but it didn't make mention that it was only on specially equiped vehicles. Under the services provided it listed: "Advanced Automatic Crash Notification - An advisor can call for help if the vehicle is involved in frontal, rear, or side impact crashes - regardless of airbag deployment." f5 you can probably tell us more about this system - if there aren't sensors, is it something that takes other measurable data and makes assumptions about crashes?

Re: Impact detected
 

Yes, the SDM has a program known as near deployment. Basically it is a program where the SDM considered blowing the bags due to a sensor or its own microprocessor, but stopped short of actually blowing the bag.
The SDM is the primary device for measuring and making decisions for frontal collisions. For side impacts, it is primarily the sensor(s).

Re: Impact detected
 

Never checked to see if this was true for "possible" rollovers.
(Should I also mention that a near deployment will freeze 5-10 seconds of data in the SDM - aka The Infamous Black Box.)

Re: Impact detected
 

So who gets the 5-10 seconds of information recorded in "The Infamous Black Box". Does it go to GM and stay there or do the local law enforcement agencies/NTSB get access to that as well.

If it stay's with GM to help design a better product that would be cool but, if it goes to the locals well...........


Where is this Infamous Black Box located at on the H3?

Re: Impact detected
 

It stays in the box - it is not transmitted to anyone via Onstar.

Re: Impact detected
 

That is true.

Re: Impact detected
 

Under the console, it is the air bag controller (SDM) and without it, air bags will not operate.

Re: Impact detected
 

So if its not transmitted to OnStar, what is the purpose of recording 5-10 seconds before the impact/event/accident. How, who and why would somebody want and get that information? I'm curoius (sp) as to why GM put that feature in there cars. The only two reasons that I can think of is a CYA for the lawyers and design of a better car, but wouldn't they want the car after the accident to study it.

Re: Impact detected
 

And what parameters does it record: speed, rpm, laterial forces, impact sensors, ABS........?

Re: Impact detected
 

Why so many questions in one sentence??????


The original design intent was two-fold; one for engineering purposes, one for cover yo a**.
GM cannot access the information without the owner of the vehicle's permission or via a court order. Permission can be given by the insurance company if they have paid the claim and now own the vehicle.
Remember the Audi fiasco about the people claiming sudden acceleration and it was they were pushing on the accelerator? Well, now if this is stated in court, GM can bring in the black box information (permission granted by owner or a court order), if the air bags were deployed or there was a near deployment, and show that the accelerator was pressed.
It has saved GM probably close to billions of dollars by having many suits thrown out of court due to the proof being in those last five to ten seconds before the bags are blown.
Problem now is that many police agencies have the software as well as many attorneys. In fact, a few years ago, a guy in a Vette was convicted using this information. GM can be used to download the information for the police or a prosecutor, BUT, GM demands a court order, they will not just do it.
The information can also be used to save your a** if you were not at fault.

In the future, all vehicles with this 'black box' information will have to be labeled with that fact. In addition, some groups are trying to get the courts to rule that this information cannot be used in criminal cases. One group is using the 5th Amendment as their case.

GM is NOT the only company to have this feature. They might have been the first.
Dealer cannot access this information via a Tech 2.
The system is always recording the required sensor information. If an air bag is deployed (or there is a near deployment), the five or ten seconds prior to the deployment (or near deployment) is written to a non-volatile memory.

Prosecutors have to be careful when asking for this information. If it finds the defendant innocent, it has to be turned over to the defense as Exculpatory evidence, or the charges dropped.

I believe the Hummer H3 records 10 seconds of information.

Re: Impact detected
 

After that response F5, I wonder if we have more in common than I thought :beerchug:

Curious though - I totalled a Chevy Aveo with the front end of my H3 and had no bag deployment (I only have the front bags) nor calls from OnStar. I guess the impact wan't hard enough, eh?

Also, is there a way to turn the tracking feature off or the SDM off for off roading purposes? I'd hate to be getting called if I hit a rut while hunting :dancingbanana:

Re: Impact detected
 

you can disable Onstar by pulling the Onstar fuse (however, you will also disable the stock XM receiver), or you can cancel the service as I have done.

Re: Impact detected
 

:giggling:

No injuries to either party. Honestly, I was astounded at the amount of damage to the side and rear end of the Aveo compared to what was mostly bolt-off/bolt-on replacement for my H3 damage. The Aveos must be made of recycled Bud cans!

Without exaggeration, the impact felt to me like it was less than go over a speed bump a little faster than one should. The H3 took the hit with style. The design must have dissipated the impact waves. It really felt as though I had pushed soemthing out of the way, rather than hit something. From your description of the physics involved with the sensors, I can understand why the bags didn't inflate. Would they have, I would have probably sustained bruising. As it stood, I walked away with only bruised pride in the fact that I had only had the H3 for a month, almost to the day of the accident. And it is my first new vehicle ever :crying:
