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.
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!
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!*
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.
@@EndOfLineTech yes but only if it was a hit and run with no witnesses or traffic cammeras, besides police don't investigate traffic crimes unless there was a substancial amount of $$ from destroyed property or an actual victim dead or alive was involved. Insurance companies will rather junk the car than pay for fixing it if it's close or beyond the amount of your coverage.
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. ;)
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
they should be fail safe but i am not certain....i had a customer wich had a melted clock spring, like really melted and the airbag deployed for no reason...i replaced it, replaced the ecu and airbag...tested the car, everything fine, no errors...i gave the car to the customer and it deployed while driving a few days later and the clockspring was melted again....luckily he didnt got hurt...by his decision we replaced the steering wheel from a similar non airbag model and removed all the airbag system...it scared the crap out of me knowing he could have got injured. i still dont know what caused it
@121bham And are you a bad guy?are you trying to say it was my fault? i checked all the checkpoints. clockspring was replaced,airbag circuit was fine, horn circuit was fine, abs ecu checked ok..road tested it to check for intermittent faults at my own risk....nothing showed up and there was no further diagnostic viable to do.....my assumption was that it was simply just a damaged and worn clocksring and that voltage from the horn shorted into the airbag making it deploy...was i supposed to rip the entire harness off of the car and check all the wires and lines searching for a most likely non existant fault??maybe charging him 100times the market value of the car?that was an isolated and weird incident and that shit can happen even if you go by the rules....and i did go by the rules on that one....then the customer asked to remove the airbag system and agreed for the possible consequences and that was a gentlemans agreement, here were i live when you agree something you keep your word....the world of stupid lawsuits is in the US of A...if he even tried to blame me i could simply deny that it was my fault, say that somebody else tampered the system and many other excuses so not worth trying... What rules my work is my conscience not the fear from the court room. And when you are 100% transparent with you customers thats all that matters
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.
on oldschool cars, yes. Now with CANBUS everything is stored in the multiple ECU's and can be accessed through the OBD port with proper hardware. it shows speed, G-forces, engine RPM, accelerator pedal position, steering angle, etc... for example, if you rear-end someone and say you hit the brakes but they didnt work, and someone takes it to court, law enforcement can have the dealership look it up on the vehicle and find that the brake pedal was not applied and the accelerator (APPS) was.
Most newer PC's do not have a serial port. and although there are USB-Serial adapters, not all software works with them, and they are a pain to set up sometimes.
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.
That's not firmware. It's just crash data and constants. The microcontroller that he disabled the crystal on very likely has its own internal eeprom or flash that contains the application firmware.
The short on the crystal was to disable the microcontroller from accessing the eeprom too. He applied power to the eeprom chip without desoldering it, which meant that the processor was actually powered too. Shorting out the crystal just halts that microcontroller, and any chance it would interfere with the eeprom.
Did it last week to a 2015 civic my roof bags blew and belts ten seconds after I plugged it in , that’s what I get for paying 50 bucks when I coulda got a module for 200 Maby 3 used on eBay and not have to take chances
kosmosleha locally had about ten reset with him before never had a issue till this last time they just blew up on they own wasn’t even the bags it was reset for
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?
Oh okay got you. For example if I have my appointment for the dmv in a few days and didn't find a replacement, can I plug in a resistor for the airbag light to turn off in the mean time right? Is that what a resistor used for most of the time??
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.
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?
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?
@@robertsteich7362 well it must have, because before he wrote the new code to it, the airbags were disabled. so yes, that chip does directly affect the other components of the SRS. they will not function if they do not read the right code from that chip.
@@frostbite1991 and that's exactly why he copied the different data from the other chip into this one.. basically making it like an uncrashed module.. if the system had an issue i most certainly believe it would throw a code of some sort.. and that chip is just there to store the crash data.. one of those hex numbers was basically an enable or disable flag for the cpu thats elsewhere in the module to operate and communicate with the rest of the car.. once that flag gets set it basically shuts itself off.. copying the virgin data allowed it to come back online and operate.. i guess a test would be to make a dummy airbag and simulate a crash by getting a junk yard crash sensor for testing and smacking the crap out of it to fake a crash and see if the fake "airbag" deploys could be a resistor and and light bulb to simulate the bag being there.
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?
Guys. Please don't mess with safety electronics. Just replace the computer with some used one from eBay. By soldering to that EEPROM you're removing coating that protects it from moisture and you risk shorting some of the pins. Not to mention ESD deposited in the electronics during the repair. The ECU may fail at the worst moment and leave you with no airbags, tensioners etc during a crash
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?
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!
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
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
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)
Hi...one question. My seat airbag deployed after a small collision and the airbag light is blinking. Can I just bought a new airbag computer and install it with a new airbag or do you have to program it to the car?
speedkar99 so it doesn't have to be programmed to the car? Have mine out about to pay about 50 bucks to have it cleared and wait for shipping.......ebay service listing
*Brilliant. Your intelligence is spooky; you belong at MIT or greater. You sound Indian (country). Are you a US Citizen? We need young minds like yours, Sir.*
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

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!
is this the only way to do this? or can I buy a pro scanner that will reset everything one I throw at it? Look complicated as hell bro!
Yes , a proscanner is the professional option
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
Depends on the car. Not all need the VIN to match
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
I basically copied the non crash data over and it reset.
@@speedkar99 but having another unit clean, it would be easier plug and play it
hi am I correct.. obd diagnostics wont see which airbags/tensioners have been deployed until the data module is reset?
In my case yes, even with techstream
Where can I get this done? I rebuilt a car and am experiencing the same thing.
There are companies that reset them. Most body shops deal with them
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)
Hi...one question. My seat airbag deployed after a small collision and the airbag light is blinking. Can I just bought a new airbag computer and install it with a new airbag or do you have to program it to the car?
Depends on the car. If it's old enough just swap over the airbag computers.
@@speedkar99 its 2006 toyota aygo
Thumbs up......Easiest fix for a 2006 prius airbag deployment? Can I just swap with another module?
+Ro Z yes as long as the part number is the same
speedkar99 so it doesn't have to be programmed to the car? Have mine out about to pay about 50 bucks to have it cleared and wait for shipping.......ebay service listing
Can you give me the half of brain. You are smart.. high tech work
Thanks very much

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 ?
No. You'll have to get an aftermarket programmer since these are meant to be replaced by OEM not repaired
@@speedkar99 which programmer would you recommend in these situations
What's the purpose of shortening the crystal?
So it doesn't bother the rest of the circuit while trying to write to it
It's That Simple !!
It sure is. Now go find a clean EEPROM dump
What would happen if you just removed the EPROM?
Bad things could happen
I was wondering why my 05 Camry 4 cylinder has a non-functioning airbag for the passenger, even though someone is sitting there.
Wouldn’t replacing the chip do the same?
Yes that works too
but you would still need to program the new chip
if you unsolder the eeprom wouldnt it be safer and easier?no need to short the crystal etc...right? no stating just asking
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
I need eeprom program for outback 2019. Do you have such? And do we need to reprogram module to the car after flashing?
Would this virgin code also work with other car brands? such as a Honda or something..
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?
Scan it with techstream
