- In this video I show you how I normally test the seat belt pretensioner when I get B2292 fault code. I also show you how I simulate the pre-tensioner just to make sure if the component is faulty or wiring.

I like the simplicity of the home made resistor been using it for years in the dealership I work at so great video nicely presented as all ur content is....but I've now moved on to a decade box n switch between them both....great channel brilliant...
Hi my friend, thanks for sharing your experience and watching our videos
I was working on my 2010 ford ranger and my simple Bluedriver scanner pulled this code for the air bag light. It came on intermittently and I was able to isolate it to a faulty connection to the pretensioner. It's important to me to be aware of any precautions to take when servicing an SRS system and to understand how things I work on actually work ! I learn best by seeing things actually applied so I watch a lot of relevant videos. This by far was the best, thanks for sharing your skill and knowledge !
Thanks for sharing your experience 🙏🙏
You áre great on diagnóstics, thanks for sharing your knowlage
Thanks for your nice comment.
Perfect Perfect tutorials, thanks
Thanks 🙏
Thank you very nice, what's scan tool are you using
Thanks for watching. This scan tool was Carman Scan but many other scan tools can do very same thing. It’s really depends on the type of cars that you are working on. This scan tool is good mostly on Korean and Japanese cars.
I have a 6 ohm resistor that was used on a LED taillight, can that be used to test or does it need to be 2.2 ohm?
Hi my friend. 6 ohm is a little high, but sometimes airbag unit considers it in range and accepts it. The best thing is to check the live data after inserting the resistance, if you see it shows almost 6 ohm it means that pretensioner was broken.
Well done for fantastic explanation
Thanks a lot 🙏
thanks for the video, i have a question, how did you determine the two wires responsible for the resistance
The best way is by using the wiring diagram. The alternative is just to trace the wires. There were two wires for the buckle switch and two for the pretensioner, just trace the wires and you will find out.
@@AutomotiveDiagnosis thank you very much

Hi was wondering if maybe you could help me
I changed my seats in my Vauxhall vivaro van 2013
And fitted bmw e60 Lci front seats
Can I use the bmw pretensioners or would you recommend to swap them back to the Vivaro tensioners
Really appreciate any advice
Good teching, May I ask question, What is the object you used for simulation?
Hi There, Thanks for your comment. That's a 2 Ohms resistor. Because the internal resistance of pre-tensioner and airbag is about 2 ohms we can simulate it like this to find the problem.
Thank you for the answer
Very well explained 🙂
Thank you 🙂
Make detail video on how to use oscilloscope & how to diagnosis on scope plz it's my humble request
Sure thing. My Oscilloscope is broken, but I’m buying one very soon. Will make so many videos for how to use oscilloscope for sure.
Very well explained 🙏🙏
Thanks 🙏
Hi,
What type of tool do i need to use to find out the right amount of resistor to use?
In your case how did you know the tensioner needed a 2.2Ohms?
Can i use a ohm meter?
Thsnks,
Hi there, normally you can find the value from the workshop manual or scan tool, you see the resistance value in this video when I show the live data. The common resistance value on many make and models is between 1.8 to 2.2 ohms. Also, you should NEVER check the internal resistance of pre-tensioner or airbag as they might get deployed!
Wonderful video
Thanks
Could you do the same thing with just unplugging the pretensioner as well shouldn’t it show nothing?
Thanks for sharing
Thanks for watching 🙏🙏
👍👍
Can we do this simulation on the airbags too?
Yes, normally airbags resistance is similar, we can simulate them in a same way but JUST for diagnostics.
Thank you so much 🙏
🙏
How is the buckle released from the bottom unit of pretensioner
We can’t pull them apart , They should be replaced as one unit.
Is the "simulator" just a common 2.2 ohms resistor?
That’s correct
Yep... Work like a charm :)
@@AutomotiveDiagnosis what sort of wattage would you recommend for the 2.2 ohms resistor?
Sir please answer my question or if anybody knows tell me, my check engine light is on and it shows that crankshaft position - camshaft position correlation bank 1 sensor A and B so should I change my camshafts sensors or both camshafts sensor and camshafts adjuster , mechanic told me to change camshaft adjuster so I'm confused what should i do my car is c250 benz 2012 please answer thanks. Codes are P0016 and P0017.
Please watch our video for P0016.
What would be the required wattage of the 2.2 ohms resistor?
Wattage doesn't matter. The current going through the wire is almost zero.
Is not possible to stimulate the Seat belt pretensioner with Test light instead of Resister
No my friend. Resistance must be a part the circuit and has to be about 2 ohms.
Where did you reside?
nice
Thanks
