- This presentation consists of four parts: Part 1 - We describe how airbag modules work including the internal components. We open different modules and point out the different component parts and how they work. We also discuss how a collision is sensed and how the module reacts
Part 2 - We use an actual module from a Toyota Sienna. We show how crash data is stored, where it is stored in the module eeprom and how to use the Andromeda Automotive Kit to clear the data. You will see a simulated crash, the resulting crash data and then the clearing procedure.
part 3 - Using a module from a 2015 Honda Civic we show how to locate the eeprom which is in a tiny TSSOP package. We then show how to attach to the part using the Precision Probe Set. After the probes are connected we show how to read the data and clear the crash data using our template procedure. We also show the document which explains how you can make your own crash clearing templates to add to the system library.
Part 4 - Using a Subar Outback module we show how to use a crash data clearing website to accomplish removal of crash data by emailing or uploading a crash data file, having the crash data removed and then how to program the cleared file back into the module. We also show how to create a dedicated directory for saving your airbag files.
In this video you will learn: How to clear crash data, How to reset an airbag module, how to reuse an airbag module plus how to use a crash data scrubbing service.
Thank you for a great tool. Also, for your time and dedication in continued support 👏
We appreciate you being a customer. Don't hesitate to contact us if you have a question.
Thank you so much for these videos! Still waiting on that full blown EEPROM class by you ;)
Glad you found the videos informative. We have two courses coming to Teachable. One is a memory course (4 hours). The other is a microprocessor/microcontroller course (5 hours). You'll get and email plus we'll post a video outlining the contents.
@@andromedaresearchlabs7826 yes! I am so excited to hear this news!
Thank you for sharing amazing video 🙏
Thanks. Glad you found the information helpful.
Thanks Mr. John
Im beginning to understand!!
If the video helps you understand then we were successful.
So for the airbag light to be removed. Everything needs to be fixed already. Seatbelt, airbags.. etc once that is fixed and you clear the crash data, it should turn off the airbag light? Or would you still need to remove it with a scanner
Your comment abruptly ended. I assume you reference a scan tool. The answer is that if the microcontroller in the module scans the eeprom and the contents does not contain crash data (virgin state) then the airbag light will go out. If it does not rescan for the cause. The code in the microcontroller determines if the SRS system is functional.
How do I get this "Working with airbag modules" work sheets ? On your website, you have all the "work sheets" on the locksmith kits. I bought the locksmith #2 kit and toughbook. You say on your videos if you buy one of your kits, you can upgrade by buying the accessories needed. I would like this work sheet for airbag modules and willing to pay you for this if possible and any accessories needed to complete this.
Since you purchased the Toughbook it comes with the airbag files already installed. If you would like a copy of the physical airbag addendum send an email and we'll provide it for you.
@@andromedaresearchlabs7826 Thank You Very Much and I am Buying Much more from your Outstanding company. I also have been telling others about your RUclips Channel. Much Thanks again !
where do i know where press path is on my computer? You say you are going to press path
The PATH command is a command in our software. It's in the main command list. To set the working path, where you will load or save files, you press P and choose the drive or folder.
@@andromedaresearchlabs7826 press "P" not press Path. I take everything literally,lol. I see now😅
Hello.
How do you know where are the crash code ? Do they always appear as 0x78 or "X" when set and always as 0x00 when unset ? And why so many byte to store crash data that only appear as 0x78 or "x" ? Aren't they related to the number of airbags or to other information ? Don't they inform about how hard was the impact (in g or m/s² in SI standard) ? I don't see the advantage of having bigger EEPROM to store more data when it stores only a bunch of 0x78s.
You don't know. There are services and software which has determined where the data is stored. Why so many bytes? Ask the folks who wrote the airbag code. They decide what to save and where.
@@andromedaresearchlabs7826But to understand well, the services or software you talk about, I guess they compare clear or virgin module with some with crash code set to deduct the byte that indicate crash code ? You didn't respond if set crash code always appears as 0x78 or "X" when set and always as 0x00 when unset. I think I noticed that was the case when you made the demonstration on different airbag module in this video.
@@Llop66 Yes, they either compare to a virgin module or have insight into the manufacturers information.
I have a question how do you the position the clips go on sorry if it was pointed out I must have missed it thank you in advance

If you have a module, containing crash data, and you want to reuse this module on a similar vehicle model in the future.
Can you make the module VIN free and install it, in the new similar vehicle, and it will be adopted by this vehicle, and have it's VIN number? 🤔
It's might work but programming a virgin file is the only 100% guarantee for success. Also the module model numbers must be identical.
@@andromedaresearchlabs7826 okay, but where do you get the virgin file from? 🤔
Search the internet. Try digigasl kaos or mhh auto.
Do u have clear crash data for every car module and each year
No. We have a comprehensive set of templates for eeprom based airbag modules. If we do not have a template we provide guidance to crash data removal websites.
Hi how about the climate control modules that i think just store the data in the big chip?
If the data is stored internal to the module microcontroller (eeprom is on the silicon) then there is no communication standard directly to the part. In other words, unlike eeproms, microcontrollers have no standard connections or protocols. They're all different. The only option is via J2534 assuming your tool and the module supports the commands required to access the module data.
Why can't you just swap the eprom
You can as long as you know what you're doing and don't make a mistake. Swapping the eeprom is three soldering operations' removal of the target, removal of salvage unit and cleaning the pads then soldering the source on the salvage assembly. Also if you break a pin or lift a track your path back is gone. In circuit cloning is faster and safer. Attach to source part, read, move the clip and program.
Hi I need your email address i need to buy AR32A Kit and need some more information regarding the power sources to plug it in to 240V power supply here in New Zealand.
