So all you need to hack your SRS module is... another functional SRS module... oh. I do dig this stuff, its neat to see what people can do. Thanks for the video.

I need to expand my "best channels" list because of you. Great lighting, great room tone, and great explanations! *Edit: the toothbrush, and then the outtake with the duck!*

It is genius people like you who make our day ! Thanks for the video man and keep up with the good work !

really enjoyed this video, thanks.I watch more and more of you're videos every day. Saves me pulling stuff apart!

Doing research on these ACM's, you do a great job explaining everything. Keep up the good work man!

Ignore the haters, this was obviously something that you wanted to explore and it was a success. It shows that technology is not inaccessible for the average person if they have the desire to learn!

One of the best how to's I've seen. Awesome I love it!

High tech pentium 4 and hightech toothbrush pointer :D Great video as always! (How many cars do you work on?)

That duck is excellent in the end! This is known as comparison engineering going on along with hacking. Great work uploaded. thanks.

For the people who say it is illegal. First - there are laws on place that require the vehicle owners to operate their vehicles with all the safety equipment being in working order. To make it simple, is against the law to use your car when the air bags, seat belts etc are not operational so the owner is required to make the air bags and seat belt operational as soon as possible . There is no law I'm aware of that prevents you from fixing the vehicle you own when you have to get it fixed before driving it again according to the law. To say it is illegal for somebody to reprogram a computer chip to make their equipment working again would be the same as to say be illegal to reinstall Windows OS on a PC or to clear vehicle trouble codes using OBD2 reader. To apply same scenario, it would be illegal for you to replace your car light bulbs on your own without going to an official Toyota mechanic. Second - an ability of the vehicle to record certain data doesn't make you responsible to retain that data unless there is a court order in place for you to keep it or you are doing it with a purpose to destroy an evidence of an illegal activity. Your desire to operate your vehicle with life safety devices working outweighs any possible legal reasons for you not to have that option. It would be next to impossible for any court to make a statement, that fixing a life safety device in a timely manner according to the law was actually against the law since it has destroyed an evidence of some sort. There may be laws that require car dealers to use certified equipment in order to do the described procedure and copyright/trademark/patent laws protecting the technology, but usually those do not apply to the car owner fixing his own car. In this particular case, it was not against the law for him to have a copy of the computer code installed on his own vehicle. I may see DMCA laws protecting the code, but not for the end user who owned a license to use it to begin with. The worst case scenario I see is that the car owner may be required to verify with an officially certified shop that his air bags are in working order after the repairs he has performed. There are specific laws against tempering with odometer readings but those are very specific to a single device and do not apply here.

You are the best auto mechanic in the world sir A+.

Dear speedkar99, You are a genius with auto mechanics and electronics. I would never mess with surface mount electronics components like you did.

Two advices, though: 1) never do it, until you sure that either srs unit doesn't have crash sensor, or this sensor is working fine (there is works-once-only sensors) 2) turn on ignition first, only then connect negative terminal. never sit in the car when turning ignition on first time after doing work on airbags system

Good Video, in some cases you can access the EEPROM by using the OBD Port. This makes it much easyer. I don't know if it works with Toyota. By the way, the toothbrush should be replaced, too. ;)

You're very good, I'm impressed

5:10 I liked the duck

I love it! rewriting code is not that hard if you know what you are doing. Its funny because I taught myself programming from an Apple 2c back in 1990. The school I cleaned had an older Apple with a floppy drive and lessons on how to write code. When you were done, it would display designs that moved or just basic crude pictures. The point was teaching you the basics and how they worked. As long as you can acess the E- prom or hard memory , you can hack anything. There are guys that get paid top dollar to write these programs. The hardest part is deciphering their code. Auto makers are NOT going to pay anyone top dollar to include a antihacking software. It would too much.

Omg using a toothbrush as a pointer. Frickin' Hilarious!

Damn so SRS control modules are basically a “black box” within a vehicle!

Time to get a fine tip soldering station, lol. Great job!

Excellent advice and content. It would be great to have a more detailed step by step of what to do because there are several steps from removing the unit to reading it including where to get Toyota's diagnostic software and the ponyprog etc etc. It would be great to see a more detailed vid, but great work.

Thanks learned a lot great video!

This isn't illegal. It's what must be done in rebuilding a car.

Good job. Fantastic video

My airbag light came on out of no where and it flashes once then nine times. It does this 5 times in a row then stays solid. I looked up the code and it says the memory is full. Will doing this clear the memory and remove the light?

very educative. kindly do more videos .very enjoyable show indeed. Thank you

Thanks for a very informative video, I like your toothbrush!😃

THANKS for you teaching

Fantastic. Thanks!!!

Wow such brilliant info man

Very useful Video thanks for making it

Haha I love this. Are you an embedded firmware engineer?

high quality tutorials

your way too smart dude, great video!

The Duck was like quack quack quack and that translated to blah blah blah so the duck was mocking you lol

Great video thank you. Is it for all cars like that?

I am glad I stayed long enough for the DUCK

he save us a lot of money thank you

holy crap! IVE DISCOVERED SOMTHIN AMAZING!!! AGAIIINNNNNNNN!!!!!!!!!!!!!!!!

Lol. The duck is an informant for the police you talked about earlier. 😁 He just caught you.

I successfully replaced 2 airbags on my car , the only one left is the curtain airbag but I cannot find a replacement. I need to pass dmv inspection but the airbag is still on , if I reset the airbag module will it remove the airbag light on my dashboard?

Does any virgin non crashed module work? Or do I need the same module of the vehicle being repaired?

if you unsolder the eeprom wouldnt it be safer and easier?no need to short the crystal etc...right? no stating just asking

Good ! please make more videos for showing the various leads of EPROM and from where to source software for Win platform

I wonder what happens if the single read/write line (pin) to the eeprom is defective - like let's say it was locked into the "read" mode... such that the eeprom is never written with accident data, that would preclude this problem altogether?

great knowledge!

Gotta be genius if you use a toothbrush as a pointer and have conversations with ducks.

Great video! I've got a 2012 Prius that had a very low speed crash (5 mph) that somehow set the airbags off. Replaced those, can use Techstream to access SRS, found codes, cleared them, they don't come back. No problems communicating using Techstream ... "No codes." But I still have the airbag light on, as you show here for the Corolla. Does this still indicate the same problem you present here, even though Techstream can read, clear, and confirm no codes? Thanks in advance for any help.

Hello - What is the likelihood (or is it even a possibility?) that a repair shop or other company could or would reset an Airbag Control Module in a 2017 Subaru WITHOUT CLEARING THE CRASH DATA? (I realize you can't speak for the practices of others, but I would like your opinion.) Is it possible that even though the hard codes have been reset, airbags replaced, etc., that the data regarding the actual crash is still lurking inside, or is that an unlikely/remote possibility? (The vehicle is not throwing any airbag or other codes and both airbags that deployed were replaced.) Thanks for any information you can provide!

Just one question, why are you resetting your EPROM instead of using the other unit? I crashed my Peugeot 307 with side and curtaing airbags, and both front seatbelts deployed. I replace the ECU from a yunk yard, both seatbelts and 2 airbag and I got my car fixed without programming anything. Thanks

How the hell did you figure all that shit out man you must be a hacker lol very good 👍

Thanks for the video. If i dont have a good module, how do I know what data bytes to clear?

Wow very smart u get a sub, almost similar to changing esn on phones good info.

Cars and computers. I love it

Would it not be quicker to de-solder the good eprom from the non-crash controller and solder it into the original? Presumably this Toyota is like a lot of other cars of the era where the control unit is coded to the car so you can't replace a faulty controller with a second-hand one?

Good job as always

Lol im literally in the process of doing this now, one problem i ran into was that i thought i was using 5v1 zeners but i was not, this was giving me a write error before. I received my 5v1 zeners in the mail today and of course it worked, i ended joining an airbag forum and someone was able to send me a clear code for my airbag module. my problem is that i dont know if the code will work, i dont want any of my airbags deploying when i go to test it. so i started swapping out my airbags with 2 ohm resistor to trick the computer into thinking i have airbags plugged in but its such a pain, if i keep my airbags plugged in and the codes wrong will my airbags deploy? or do the sensors have to be tripped? is this chip just storing data or is this the deploy data?

i am no expert or anything but if you dont really know what that hex code means, you said you dont know how decode that, how can you be sure that the computer will do its job in a future crash? have you tested it? or just because the airbag light goes off you are confident it will work?

Would this virgin code also work with other car brands? such as a Honda or something..

I need eeprom program for outback 2019. Do you have such? And do we need to reprogram module to the car after flashing?

its nice the entire firmware can fit in a screen shot ;) thx

I had a flood car on airbag module,the light is on with code b1613, b1618.should I wipe the EPROM clear? I can't erase it by scanning tools.(Toyota avanza 2019 f:65)

Great machine and electronics

Awesome video! I subscribed to the author

Thank you so much !!!

My mind blow up hhhhh. Ur brain good work

Thanks learned a lot great video

Neat show and tell. Not practical for your average Joe. Thanks for showing your ingenuity.

question - can I use toyota techstream to program in a new air bag module if I pull a used airbag module with no crash codes from a used car ?

bought an miniwith front airbags gone of... I found an set of rondt airbags and seatbelts and aibag computerbut you have also go to replace crach sensors? or not?

hi, can you tell me whether to replace Tout with the letters FF on the airbag computer to reinstall the crash. because my device does not erase automatically. THANKS

Great video! I have a 2023 Corolla with the airbag light on and no codes. The car hasn't been in any accidents. Can the SRS module be faulty?

Good job man your explanation is great. But i didn't catch up with the circuit connection you made with the eeprom. Can you help me out?

Could you please tell me where is that module on 2007 fusion! Thanks

hi am I correct.. obd diagnostics wont see which airbags/tensioners have been deployed until the data module is reset?

I'm thinking about just going to the salvage yard and swap my module with one there that hadn't deployed. Easy peasy.

I have a crashed 2004 Toyota Matrix. Could I flash the same data you did in your instructable? I can't seem to find anything else on the web. Nice Post!

Do you think this can work on a 2004 f150 or can a new module clear all the codes so it can work properly?

Nice video

I was wondering why my 05 Camry 4 cylinder has a non-functioning airbag for the passenger, even though someone is sitting there.

nice video

Can you send datasheet for this chip i can't find

you are my hero !!

hello ,where can I find wiring diagram about ECU or airbag ... ??? thank you

Fantastic !

So if you need a spare virgin module why not just plug it in? Is it coded to the specific car or something?

You are a genius

That was clever.... But I don't follow why the clock crystal was shunted, which would just make a pass-through?

I am the first one to comment and 2 to like this video

Came here looking to try and do this myself...... Reality just set in, I’ll pay the $50.

How do you know that crash data is stored in eeprom? It could be inside any chip. Is there a software that tells you that

Dang, my Lexus GX470 has this light, but it’s never been in a crash as far as I know. Do you know what to do?

Can you actually replace it? An worker told me something about programming the VIN into the srs control unit. Or was it bs*? I have to replace my module and i already paid thousands for repair service, this thing always fail. Im an engineer, not an idiot. I just buy one by my own, i only dont know whats going about the vin id. My car is from 2002

Good job

You are a supergenius or something.

Quick question, I replaced the new srs ecu in a Mitsubishi 2012 but it throws a code that reads recalibrate srs ecu. What’s should I do ?

Hi I see your video it was awesome I want to ask 1 thing how can i get the techstream software?

i have cg100 airbag ecu repair i use it to repair toyota highlander 2015 after i finish the repair is wrinting airbag ecu manufuntion pls i need ur help

Why not use a simple Carprog for the whole process ?

wow! super cool!
