- In this video I show you how I simulate the airbag fault by simulating the airbag. When there is a fault on any airbag, we can not simply test the airbag itself, we have to go for testing the wiring one by one, and at last, we might be unsure between the airbag control unit or airbag itself. This video shows how we can simulate the airbag to make sure if it is faulty or not. I did this diagnostics in the driver airbag, but it is applicable to all airbags and seat belt pretensioners.

All my congratulation for all these videos and infortion
@@rolandangelmardkibouilou7032 thanks my friend. I’m glad you liked them.
I like your explanations, very easy to understand and very professional.
Thanks my friend
Very good! Thanks.
Thanks for watching
It was just like I was in a classroom, Thanks buddy
Glad you liked it!
This was a real diagnostic class, thanks man.
Great to hear!
Very comprehensive 👍🏽
Glad you think so
started watching your vidios and now i can't wait till the next one great tech info thank you
Awesome, thank you!
Very nice thank you!
Glad you liked it!
Very helpful, thanks
👍👍
Thanks a lot for the great video.
Glad you liked it.
I learned a lot, thanks
Glad it was helpful!
Very informative educational video. I learned a lot
Glad to hear it
You can also use a digital volt meter on the airbag itself, and measure the ohm reading. As you saw in your scan tool, you should get about 2.8 ohms (this is for every steering wheel airbag in all manufacturers). You will need to cut a small tip off a wd40 red spray nozzle and slide it down one of the post as to separate a contact point down at the bottom of the connect on the airbag, otherwise you will not get a correct reading.
Even if you can get the resistance reading on the scanner, you should never check the airbag resistance with a multimeter as it could deploy the airbag. I’ve seen some cases of airbag deployment while checking it with multimeter. The whole point of using a dummy resistor is to avoid testing the airbag with a multimeter.
@AutomotiveDiagnosis I have never heard of an airbag being deployed using a DVM ever...in fact it's impossible...if you notice on the steering wheel airbags there is 2 connections (4 contact points) You would have to supply 12v to 2 out of the 4 pins (1 on each connector) to deploy said airbag. You can send in airbags to have them refurbished, and they use a digital volt meter to do this simple yet effective test to see if indeed the airbag is at fault and if so proceed with the work. I have done this many of times myself (checking the ohms reading) and never had one blow up, in fact I learned this very tip from the professionals who indeed refurbished them...
Good video but I would of cleaned the connector in case of bad connection and look at data again.
Correct, that part is not included in the video only because it’s a must in these cases. Anyway, thanks for highlighting that.

Thanks
I liked it
Glad to hear it
very useful videos as usual
Thanks my friend
Thanks my friend
Good video thanks for sharing

Can you make a video for us on the immobilizer system, how the signal is transmitted from the key to the coil and then to the immo box, and how to check this system in the event of a malfunction in it?
Sure thing my friend
Hello, I like your lesson and I'm learning alot from it. I have a few questions. If the car was recorded being in an accident and airbag is at fault according to your test (high ohms), is it common for airbags to fail electrically even though not physically being deployed? I was hoping you would've shown Driver AB stage #1 resistance to compare with the stage #2 you found. I did see Driver AB module resistance just below but not sure if its the same as stage #1 as you mentioned. I understand the use of a 2ohm resistor for quick diagnosis but can both airbag plugs harnesses be swapped on airbag #2 for #1, #1 for #2 to see if high resistance moves in the scanner and maybe could rule out or reveal loose connections?
Hi there, thanks for your comment and very nice questions. Yes, it’s common to have a faulty airbag even if it’s not deployed, that’s why we have to simulate it. Swapping the connectors is a good idea to find out the faulty point, but on many airbags we only have one stage which makes it impossible to swap the connectors, therefore we still need the simulation. On this car I had a parameter on Scan tool for other stage as well, so it’s not a bad idea to read the live data before any sort of test.

Great video. I own a 2012 Nissan NV3500 passenger van. I am converting it to a camper van. The van has rear airbags. I would like to remove them because I want to install overhead cabinets. Can I use an airbag simulator after I remove the rear airbags to keep the dash light off and use my front airbags?
Hi there. Yes it’s possible. But as you said, only for simulating the airbag when you remove the seats or change the application.
@@AutomotiveDiagnosis Thank you
Salam brother
Can you simulate both stage 1 and stage 2 with simulators instead of leaving one stage attached to the driver airbag? Thanks for the video.
Hi my friend.of course you can.
Great video. How did you make your air bag simulator?
Thanks, it’s just a 2.2 ohm resistor, you can also buy it from eBay or Amazon.
Very 👍 informativ video
I am new this field
I want to purchase scanners and work on it in Dubai and now I am at live in Pakistan
Plz help me about scanner
Thanx bro❤
Hi there. It’s really based on the types of cars that you will be working on. But if you will work on multiple vehicles, one of the best scanners is Launch.
If the problem was in the control and it was changed, how do you program the new control?
Programming can be different based on the make and model, but here is one example:

Hello, I replaced the resistor, but airbag light still on! How can i reset it ?
This resistor is only diagnosing airbag. So, first of all you need to make sure that you have a fault code for that airbag you are working on. After that inserting the resistor into the connector, you need to erase the code with a scan tool, if code comes back, you have a fault on wiring or airbag control unit.
Why my ohm in not stable it keeps going up till 10ohm and then airbag light go back on
There can be a loose connection on the circuit
9103 and 9163 anyone have any ideas it's a 2006 c280
9103 is driver airbag resistance too high that can be diagnosed as explained in the video.
Hello sir we can apply this solution for all cars pls reply
Hi my friend, I have tried it on many cars, it’s applicable to majority of them.
@@AutomotiveDiagnosis
Thank a lot sir
Sir it is very difficult to get wiring diagrams could you please guide me how can i get it
There are different ways to find them. Dealerships normally have access to the online technical websites. But there are some websites which offer wiring diagrams in return to subscription. I will make a video about that very soon.
Thanks sir I will wait till you make it
