🔌 Seguridad al usar el cable de alimentación OBD para el camrecorder

En este primer párrafo, se discute la seguridad de usar un cable de alimentación OBD para un camrecorder en lugar de cablearlo directamente al interruptor del vehículo. Se menciona un video anterior que tuvo un gran éxito y se ofrece un enlace en la descripción para aquellos que quieran verlo. El presentador, Alex, explica que, aunque algunos pueden estar preocupados por conectar algo que no es un dispositivo de diagnóstico al puerto OBD, hay más dispositivos en el mercado que utilizan este puerto. Se menciona que las compañías de seguros envían dispositivos OBD2 para monitorear el uso del vehículo y reducir el costo del seguro, lo que implica que el riesgo de dañar el vehículo es bajo. Se enfatiza que, aunque el puerto OBD fue diseñado para diagnósticos, su uso se ha expandido con dispositivos adicionales, y se aconseja entender cómo funcionan estos dispositivos antes de tomar decisiones sobre su uso.

🛠 Explorando el interior del adaptador de alimentación OBD

El presentador, Alex, continúa explicando cómo funciona el adaptador de alimentación OBD y qué componentes están conectados. Se menciona que el estándar J1962 controla el tamaño y las funciones de los pines del conector OBD, pero deja algunos pines libres para su uso por parte de los fabricantes. Al desmontar el adaptador, se observa que solo se utilizan tres pines: dos para tierra (pin 4 y pin 5) y uno para poder positivo (pin 16). Se destaca que el adaptador no interfiere con la computadora del vehículo, ya que solo se conecta directamente a la batería y al suelo. Además, se discute la protección incorporada en el vehículo, como el fusible entre la batería y el pin 16, que protege contra cortos. Se menciona que, aunque el estándar recomienda protección, no es obligatoria, por lo que la presencia de un fusible varía según el fabricante del vehículo.

⚠️ Riesgos y precauciones al usar el puerto OBD

En el tercer párrafo, Alex aborda los riesgos asociados con la conexión de dispositivos al puerto OBD, enfocándose en la posibilidad de que un objeto extraño cause un corto entre pines que no deberían estar conectados. Se explica que este riesgo es similar al que se corre al conectar un dispositivo de diagnóstico estándar, ya que ambos son fabricados y probados en fábricas. Sin embargo, se señala que la probabilidad de que un objeto extraño cause un corto es baja, ya que los pines no utilizados están diseñados para no interferir con los que sí se usan. Se sugiere que, aunque existe un riesgo mínimo, la única manera de evitar daños electrónicos en el vehículo es no conectar ningún dispositivo adicional al puerto OBD. Finalmente, se menciona que el puerto OBD está diseñado para su uso y que, en la vida del vehículo, es probable que se utilice en situaciones como inspecciones de emisión, lo que implica que su uso es inevitable en ciertos contextos.

play00:00

on a prior video i showed you how i

play00:02

power my dash cam using an obd power

play00:05

cable instead of hard wiring it to the

play00:07

fuse box of my vehicle and that video

play00:09

has gotten a very positive reception

play00:11

with almost a million views so if you

play00:13

have not seen that video i'll put a link

play00:15

to that video in the description in case

play00:17

you want to check it out but a few

play00:18

people were left wondering if it was

play00:20

safe to power a dash cam using the obd

play00:23

port of your vehicle on this video i'm

play00:25

gonna show you what's inside of this obd

play00:28

power adapter and we're gonna talk about

play00:30

should you be afraid and should you be

play00:32

worried about using the obd port for

play00:35

power hi guys welcome back i am alex the

play00:38

car guy and on this channel i review

play00:41

cool car gadgets and other accessories

play00:43

that i find for your vehicle so if those

play00:45

are the kind of videos you like make

play00:46

sure you subscribe by hitting the button

play00:47

down below to see more videos like this

play00:50

but now let's talk about the obd power

play00:52

cable and i'm gonna give you a very

play00:54

short answer and on the second part of

play00:56

the video we're going to get a little

play00:57

bit more into depth if you want to know

play00:59

the technical aspects of how the obd

play01:02

power cable works but let's talk about

play01:03

the obd power cable this is going to be

play01:05

connected to the vehicle obd interface

play01:08

and that powers the dash cam now that

play01:11

can potentially scare some people

play01:12

because they're wondering hi i never

play01:15

heard of somebody connecting something

play01:17

to the obd port that is not a

play01:19

diagnostics tool or that is not a code

play01:22

reader all of a sudden you're connecting

play01:24

a dash cam what is going on in fact i

play01:26

even had some people put in the comments

play01:28

this is gonna blow up your car this is

play01:30

gonna kill your car's computer and the

play01:32

quick and short answer to this is well

play01:35

not really because we are now seeing

play01:38

more devices that can be plugged into

play01:40

the obd port instead of just an obd

play01:43

scanner for example some insurance

play01:45

companies if you call them up they'll

play01:47

send you a little obd2 plug-in that you

play01:50

can put in your car and with that they

play01:52

can monitor how you're using your car

play01:54

and potentially give you a lower price

play01:56

in your insurance now think about it the

play01:58

insurance company when looking at

play02:01

anything that has to do with your

play02:02

vehicle they're looking at risk and are

play02:05

they going to send you a device that's

play02:06

going to cost your car to break down

play02:09

caution catch from fire or anything like

play02:11

that they're probably considering that

play02:13

risk very very small and therefore

play02:15

they're saying here put this in your car

play02:17

again this is the insurance company from

play02:19

your car saying it's okay to plug in a

play02:21

device into your obd port that is not a

play02:24

diagnostics tool and some of us are

play02:26

using the obd port to pull information

play02:29

of the car for performance data perhaps

play02:31

we are into racing the vehicle in a

play02:34

professional close track environment and

play02:36

we want to see real-time information

play02:38

coming off the vehicle that's when we

play02:40

can use one of these dongles so while

play02:42

the obd port was originally designed for

play02:44

diagnostics using an obd scan tool we

play02:47

are now seeing that there are more

play02:49

devices out there in the market that are

play02:51

using the obd port for other purposes

play02:54

but just because we are now using other

play02:56

devices in the obd port than the

play02:58

original intended scan tool does that

play03:00

automatically make using the obd port

play03:02

safe well i'll be very careful with

play03:05

anybody that tells you it is a hundred

play03:07

percent safe to plug this into your

play03:09

vehicle anytime you're connecting

play03:11

something into a car that is an

play03:13

aftermarket device there is the

play03:14

potential or something to go wrong if

play03:17

you don't want to have that potential

play03:19

risk never connect an aftermarket device

play03:21

to your vehicle now anybody that tells

play03:24

you this will 100 kill your car i would

play03:27

also be wary of that advice because

play03:30

there is a lot of factors and you want

play03:32

to understand how these devices work

play03:34

behind the scenes before you can make a

play03:36

claim like that but let me show you

play03:38

what's inside of the obd power cable

play03:40

adapter so we can understand how it

play03:42

functions how the obd port functions

play03:45

what safety features are built in onto a

play03:47

car to prevent this from damaging the

play03:49

vehicle and more and starting with the

play03:51

obd connector the size of it and the

play03:53

pins each one what it does is controlled

play03:56

by a document that we call the

play03:58

j1962 standard and that document tells

play04:02

the manufacturers this is how they

play04:03

should work this is the size that we

play04:05

want them to be and each pin should do

play04:07

the following function and does that

play04:09

mean that each one of these pins is

play04:11

actually doing something well not really

play04:13

the standard only covers certain pins

play04:16

some pins are left available for the

play04:18

manufacturer of a vehicle to use them

play04:20

for some special purpose so this obd

play04:23

adapter even though it has 16 pins may

play04:27

not be needing or using all of them but

play04:30

let's see what's inside of this bad boy

play04:32

which i already took the liberty of

play04:34

taking the screws apart and we can see

play04:36

here that we have the switch that can

play04:38

turn the different functionalities of

play04:40

the adapter and then we have a little pc

play04:42

where i'm going to pull this out right

play04:44

here and we can see here that there is a

play04:46

couple of microcontrollers a capacitor

play04:49

but what i want to show you is that even

play04:51

though i have 16 pins in the adapter if

play04:53

you looked in between this plastic part

play04:55

and the pc board you'll see that not all

play04:58

the pins are being used we can see that

play05:00

there's a pin right here being used and

play05:02

a pin right here being used which are

play05:04

the ones that are right smack in the

play05:06

center which corresponds with these two

play05:08

pins right here this one and this one

play05:11

and if we keep going around here we can

play05:13

see that there is another pin that is

play05:15

being used and it's underneath here you

play05:18

can see how it kind of comes out on this

play05:19

end and that pin is all the way over

play05:22

here number 16. so what does the two

play05:26

pins are over here do and what does this

play05:28

pin do right here well pin four and pin

play05:31

five are providing a ground which is

play05:34

negative and this right here 16 is

play05:37

providing positive power so that is it

play05:40

this connector is only tapping into

play05:43

negative and positive power from the

play05:46

vehicle every other pin is not connected

play05:50

so just because i'm plugging this entire

play05:52

connector you can see that the pins that

play05:54

are really only being interfaced to the

play05:56

car are a total of those three pins the

play05:58

two for the ground and one for power and

play06:01

here's where the phone begins this is

play06:03

the schematic for the vehicle where i'm

play06:04

using my obd power adapter which is only

play06:08

using three pins it's using pin 16 for

play06:11

positive and is using pin 4 and pin 5

play06:14

for negative now if i look at the car

play06:16

schematic pin 4 and pin 5 sure enough

play06:20

they are negative because they go

play06:21

straight to ground now if i look at pin

play06:24

16 that goes directly to

play06:26

my battery so am i at any point touching

play06:30

the computer the car's computer not

play06:32

really i'm going straight to the battery

play06:34

and i'm going straight to ground so

play06:36

anybody that tells you that this adapter

play06:38

is interfacing to your computer does not

play06:40

understand how to read schematics and

play06:42

the other interesting thing is that the

play06:44

document that controls the obd connector

play06:47

the j1962 standard describes that pin 16

play06:51

because it's providing power it should

play06:53

have some kind of protection and if you

play06:55

follow the schematic for my vehicle you

play06:58

can see that yep there is some

play06:59

protection they have put a fuse in

play07:01

between the battery and pin 16

play07:04

effectively protecting this against any

play07:07

kind of short and this answers a common

play07:09

question that i get regarding an obd

play07:11

power adapter is this fuse protected

play07:14

well the fuse protection is built onto

play07:16

the car however if you look at the

play07:18

standard it says recommend it it doesn't

play07:21

say that it's mandatory so just because

play07:23

chrysler decided to put a protection in

play07:26

here does that mean that your car has a

play07:27

protection that is really gonna depend

play07:30

on the car manufacturer and i've seen

play07:32

cases in electronics where there are

play07:34

multiple fuses in line maybe a fuse on

play07:36

the actual device and a fuse on the side

play07:39

as providing power so you have a total

play07:41

of two fuses but normally one fuse is

play07:44

enough two good redundancy one is the

play07:46

normal practice but earlier i mentioned

play07:49

that this is not interfacing to the

play07:51

computer and that is valid for this

play07:53

adapter in its working configuration

play07:56

because if you look at the adapter the

play08:00

other pins are going to the computer for

play08:03

example you have pin 7

play08:05

pin 12 pin 2 p9 and pin 15

play08:10

in some cases in this case because

play08:12

they're using the 2.0 engine is there a

play08:14

possibility that during the

play08:15

manufacturing process a little solder

play08:18

ball and solder is what we use to mount

play08:20

the components onto a pc board can a

play08:22

solder ball fall in between one of those

play08:25

spins imagine if a large piece of metal

play08:27

fell

play08:28

in between 12 and seven and you got

play08:30

completely unlucky that it landed on

play08:32

those two pins and it got to you and you

play08:35

plugged it into your car can it

play08:36

potentially affect something it

play08:38

definitely can because now we are

play08:40

connecting two pins that are not meant

play08:42

to be connected and having worked in the

play08:44

industry for quite a bit of time i can

play08:46

tell you that we have tests in process

play08:48

and sometimes at the end of the line to

play08:50

test that things like that does not

play08:52

happen but even with all those tests

play08:55

sometimes there are some things that

play08:57

escape and that is just the nature of

play08:59

the business and if you happen to be

play09:01

that few very very small percentage that

play09:04

that escaped and it got to you you could

play09:06

potentially have two pins that are not

play09:08

supposed to be connected connected but

play09:10

let's look closer at the risk of two

play09:12

pins being connected by accident at the

play09:15

factory here again is where it's gonna

play09:18

depend greatly on your vehicle because

play09:21

the standard that controls this

play09:22

connector does not specify all the pins

play09:26

it leaves a lot of pins unused for the

play09:28

manufacturer to use them if they wanted

play09:30

to for example in this particular

play09:32

schematic for chrysler you can see that

play09:34

chrysler is not using pin one this is

play09:37

not using pin 3 not using pin 6 so you

play09:40

can see that they're hardly using the

play09:41

pins on the obd connector if you were

play09:44

happen to be unlucky enough that you got

play09:46

a bad adapter where something is

play09:48

shorting let's imagine a shorting pin 13

play09:51

and 14. is it gonna do anything to my

play09:54

vehicle not really because the vehicle

play09:56

is not even using those pins same thing

play09:59

if that potential piece of metal landed

play10:01

in between 10 and 12 is it gonna damage

play10:04

my vehicle the vehicle won't even know

play10:06

because nothing is connected you have

play10:08

what we call in the industry a dummy pin

play10:10

one that doesn't do anything so the risk

play10:13

is reduced because now you are looking

play10:15

at that piece of metal has to land in

play10:17

between one of the working pins and some

play10:21

of the pins are actually pretty far from

play10:23

each other so when you look at pin two

play10:25

and pin four there is an empty space in

play10:28

between pin three so whatever falls in

play10:31

there has to be large enough where it

play10:33

will cross all the way from pin two

play10:36

all the way up to pin four and you can

play10:38

see on here how far that is here's pin

one

play10:42

two three four so you're talking a very

play10:45

very long distance so you're talking

play10:47

about having a very large piece of

play10:49

foreign object debris inside of this

play10:51

connector that escaped the factory so as

play10:53

you can see the main danger of

play10:55

connecting something to your obd port as

play10:58

far as i can tell is gonna be two or

play11:00

more pins being shorted out by a piece

play11:03

of debris when they're not supposed to

play11:05

be connected

play11:06

but that same possibility of that same

play11:09

potential short can occur on a normal

play11:13

obv diagnostic tool this is a tool that

play11:16

we connect as car mechanics to our cars

play11:19

all the time so the same danger of

play11:21

potentially shorting out something in an

play11:24

obd power cable is the same danger of

play11:26

connecting a standard tool to the device

play11:29

of a vehicle both of them are being made

play11:31

in factories both of them are being

play11:32

tested in process both of them can

play11:35

potentially have escapees escape out of

play11:37

the all the quality checks and can

play11:39

potentially make it to you and

play11:41

potentially create a hazard on your side

play11:44

so the only way to ensure that you never

play11:46

damage your vehicle's electronics is

play11:48

never to connect anything that's after

play11:50

market never connect an obd device to

play11:53

your vehicle but that's kind of

play11:55

realistic because the obd port was

play11:57

designed for us to use it it was

play11:59

designed for us to connect into it and

play12:01

in fact at some point in time your car

play12:03

is going to throw a code and a mechanic

play12:05

is going to have to connect an interface

play12:07

to it in fact if you live in one of the

play12:09

states that require a smog or some kind

play12:12

of check like that the technician that's

play12:14

checking your car is gonna connect a

play12:16

very similar tool either wireless or

play12:18

with a wire to your vehicle to check

play12:20

that it's ready for smog so there is

play12:23

gonna be some use of that port during

play12:25

the life of the car whether you want it

play12:27

or not so hopefully this video gave you

play12:29

a little bit of background on how this

play12:31

adapter works how the obd adapter came

play12:34

to be how it is controlling the industry

play12:36

and the different devices that are now

play12:38

being plugged into an obd port it is not

play12:41

really like a usb port where it was

play12:43

meant for you to plug hundreds of things

play12:45

in there it was originally only intended

play12:47

for diagnostics tools and over time the

play12:50

industry started to come up with other

play12:52

devices to plug in there as well when

play12:54

they realized hey if we only use the

play12:56

pins for power then that's all we really

play12:58

need and if you guys have any other

play12:59

questions regarding the obd2 adapter

play13:01

please put that in the comments down

play13:03

below and stay tuned as i have a more

play13:05

advanced video covering in detail the

play13:07

obd2 port as described by the j1962

play13:11

standard which is going to be of

play13:12

interest to anybody who has an

play13:13

engineering background or whether you

play13:15

like to learn electronics or whether you

play13:17

really wanted to know this in more

play13:19

intimate detail to really feel

play13:21

comfortable plugging it in and using it

play13:24

or not plugging in anything to it and

play13:27

not using it

play13:45

you
