The Automatic Link includes a built-in accelerometer that can detect many types of crashes. Automatic uses your phone's data connection to immediately report the crash to 911 with your name, location, and vehicle description. Now this fascinates me. I wonder what parameters are required to trigger the automatic emergency notification.

That raised my eyebrows too. I can't help but see a lot of false positives from this, maybe even just from accidentally whacking the device.

I've seen these before. There are several companies working on similar products (and things like HUDs you can get off of eBay which show you OBD-II information). The main problem with these (all of them!) is that the OBD II was never designed to be used like this. It will run the device 24/7 even when the car is turned off. So it will run down your battery in a similar way to leaving the cabin light on would do... No…

We're paranoid about not running your car's battery down. When the ignition is off, we consume less than 1 mA. By itself, the Automatic Link would take 3-4 years to drain even a cheap battery.

It is my understanding that engine codes are not public and car manufacturers consider them copyrighted information, requiring a license. I wonder if Automatic reverse engineered the codes or licensed them from the manufacturers. The check engine light is only used to indicate problems with the car's emission system. It is unlikely to provide anything actionable unless you're planning to get your car smogged soon.

Most of the in-depth codes are proprietary, but at the same time, things like mass airflow sensor info and throttle position sensors are under the standard specs for OBD-II info. So even without paying the many thousands of dollars to Ford, etc for the info, you can usually get a good idea of what's going on.

Also, the check engine light is something that can display things that people would only consider tangentially related to the car's emissions system. Things like misfires, or even occasionally transmission problems, can also trigger this light.

Do all cars have this 'data port'? I had no idea this thing existed.

Yes, it is the OBD II port, and is typically used for on board diagnostics and connects directly to the ECU. The bluetooth "dongles" have been around for a number of years.

> Honda cars that use VTEC often don't have OBD II ports.

i'm a car guy and i've never heard of this before. source?

Does the onboard computer report that the airbags have deployed?

Sudden deceleration + airbag deploy = 911?

Yes the ECU has a state that detects airbag deployment but even the airbags can have a false deploy (see the most recent episode of Top Gear for a prime example).

Earlier quoted context omitted.

Can't the dongle just kill its own connection to the OBDII port? i.e. appear inert to the car's hardware as if nothing is plugged in?

It could, but keep in mind many OBD-II ports are out of reach. The one shown in the marketing is real, but many are located on the passenger side or a lot deeper on the driver's side. OBD-II might be a standard, but as I said it was designed to be used while the car is in a garage, never while it is being driven. So there is no "standard" for manufacturers to position it.

I think what he meant was, can't the device shut itself off in software to appear as though it is unplugged. Not having the user unplug it himself.

It can read the code but that doesn't give you much to work with. You won't be able to clear the code and you will have to pay for the replacement parts and undertake the repairs yourself. I'm not sure what the situation is in the US but here in the UK, if you took your car to a mechanic purely for the sake of reading the code then it would only cost about £50.

According to the video you can clear the code, the example if if the code reports "Loose gas cap".

Let me rephrase then. Let's assume the check engine light is on due to a fault in the fuel pump. You can clear the code but you aren't clearing the problem. As soon as the problem occurs again, the light returns. In most cases the faults that trigger 'check engine' lights are in a constant state of fault until the part is repaired or replaced meaning the light will return essentially as soon as you press the accelerator.
