A buddy of mine had an accident, ran a stop sign and t-boned another vehicle. Nobody hurt, airbags did not deploy.

His vehicle has a pre-collision avoidance system that applies the brakes if it senses an impending rear end impact. In this case, the other vehicle came from the side, not something it was designed to handle.

He's wondering, and I am too, how to read the EDR in his vehicle to see if that pre-collision system really did activate before the impact.

I don't think the normal scan tools can read this, but do dealers have the ability or is there some other equipment necessary?
 
You are likely out of luck. The EDR data, while it is retrieved via the ODB-II port, isn't standardized and I don't know of any available-to-the-consumer.
I assume we're talking Toyota/Lexus. I don't even think the dealers themselves have the tools usually.

The PCS probably didn't trigger. It looks pretty straight ahead. The thing can detect rather small objects (pedestrians for example), but it doesn't look for things coming in from the sides as you noted.
 
Watch late night Tv. There are always lawyers saying if (insert faulty part of the day here) fails, or even if it did not fail and you had an accident, call us. We will make you independently wealthy because it is always someone else's fault.

"I was practicing nocturnal habits on my job when an anvil fell on my head. Lawyer J. Noble Daggett of Dardanelle, Arkansas got me $500,001. 02 for my injury. Don't trust your soul to no backwoods Southern lawyer, call J. Noble Dagget now, and get yore free money like I did...."

2016 Subaru.

Newer models of Subaru vehicles have "Eyesight", stereo cameras mounted on either side of the rear view mirror. Used for emergency braking in case of a rear-end collision and for adjusting cruise control speed to keep a minimum distance from the car ahead of you.

This is more curiosity on his part, wondering if the system triggered or not in that scenario.
 
You keep saying rear-end collision which makes it sounds like someone's hitting your car in the rear.

Eyesight doesn't look backward so I assume you to stop you from rear ending someone. Again, it is just looking forward for objects in your path. The looking to the side is limited to the lane departure warning not for crossing traffic.

Writing that took grit.

Truly.

Yes, it tries to minimize your own chances of rear ending someone else, and lessens the force of the collision. It isn't meant to react quickly enough in the case of a deer running front if you or a car coming through an intersection from the side. He's wondering if there us a way to find out if the system triggered at all, and is hoping there us a simple way to get that info.
 
Actually, the service computer at the dealership can read the EDR on the soobs. His best bet is to talk to someone in the service department and see if they'd be willing to look at it.
 
He said he contacted Subaru corporate and a dealer service this afternoon. Waiting to hear back.

Matthew,

I really don't give a rat's what the computer says. I have both a video cam and GPS that would be evidence in court of the time of the accident, speed at the time, and video proof of who was at fault. If those show I was the culprit so be it. I drive conservatively so I think they will be a good defense in court. I wouldn't hesitate to provide those videos to the judge. Yes I know the dash cam is a defensive tool that can be invaluable in court.

His fault (acutally, his wife's) and no question about it. His curiosity is to whether or not the built-in pre-collision braking system actually kicked in considering the dynamics of the accident were not what the system was designed to handle.

I don't have a dash cam, but the last time I bought a car GPS I did look at a model with a built in camera. When they record, do they loop like a FDR? Do you have to stop it or does it have some way to stop recording on its own?
 
Apparently Subaru model years '15+ are proprietary abd dealers have the equipment but are reluctant to use it in cases like this.

Other years can use this reader:

It sounds like the recorder must be removed from the vehicle to be read. I doubt he's going to be able to get it read without a lot of effort.

My dash cam has a built in sensor for impacts that stops the recording. t also has a 32 gb card that enables eight hours of recording.
 
Probably already been said, I haven't read the whole thread. I just bought a new car. It was disclosed that the computer recorded and retained those kinds of information and that law enforcement can have access to it. That implies it is accessible. Whether it can be done at the level of a dealership I don't know. I'd guess that the insurance companies know all about it. So the big question is, if I get into a wreck, should I save the box or should I fry the box, lol.
 
Have your buddy read this.
Poorly written; it seems that anyone can access the data...which negates the requirement for owner consent or court order.

1) with owner’s consent; 2) court order; 3) diagnosing, servicing, or repairing the vehicle; or 4) medical or vehicle safety research; 5) for dispatch of emergency medical personnel; or 6) probable cause of an offense.

Yeah. When I bought mine it said that, that the data was accessible without owner consent. Actually there is owner consent. You consent when you buy the car
 
I wonder if there's a simple way to disable those.
