I'm having an issue with the airbag/sensors on a 2006 GMC pickup, so I checked the sensors with an ohmmeter and diode checker. The resistance was very high one way (3 megohms), and infinite with the leads reversed. Measuring voltage drop, which is what a diode check does, shows there is definitely a semiconductor between the two leads of the sensor, so unfortunately not all sensors are as simple as yours. Very nice video. Well done!
@speedkar996 жыл бұрын
That's true, a diode could also be used as a check device as well
@LarryCook19606 жыл бұрын
Well, no. What I mean is that the airbag sensors on my vehicle, and most likely other newer vehicles, consist of more than a simple mechanical switch. Inside mine there is clearly at least one transistor / diode of some type. Your smart phone has a micro accelerometer in it for instance, which is most likely what's inside a more modern sensor. hackaday.com/2012/05/22/the-engineer-guy-explains-how-mems-accelerometer-chips-work/
@jositosWay Жыл бұрын
@@LarryCook1960 You are right : sensors are more complicated than that.I think you have figured it out by now ; The micro accelerometer you are talking about is more likely based on piezoelectric technology that says: a crystal (be it quartz or the like) has the quality of producing electric pulse upon being impacted. So the accelerometer has a crystal quartz layer that separates two metal plates that are charged with positive and negative electrodes respectively by the crystal upon being impacted or very lightly knocked. So I think that when people measures the resistance of an airbag sensor with a multimeter , what they are measuring is the resistance of mentioned metal plates. If the piezolectric crystal that is between those metal plates , breaks for a strong external blow to the car or by simple tear-and-wear, those two metal plates would be in contact (even lightly due a tiny minor fracture of the crystal) showing an abnormal resistance or even continuity. It is even more complicated if we take into account that around the piezoelectric accelerometer there are capacitors that store some charge and a tiny transducer that converts the electric pulse generated by the cristal (upon being tested or for a legit real impact) back to the Airbag control unit (ECU) to deploy airbags if needed. That amounts to a nightmare for a newbie to test such an overcomplicated sensor device that only gets a generic message when conecting a ODBII examiner: OPEN CIRCUIT IN AIRBAG SENSOR 1 !!!! Then you start throwing parts, battery and overhauling the fucking all wire looms and connectors to the ofending fucking sensor 1. A nightmare and very entertaining PITA process!!! Good luck!!!

Well you have to remember, intellectual properties are protected by Patents. Either the manufacturer settles on using someone else's patented technology or, develops their own device which then has to undergo all the testing to certify the device. So....bottom line is I'm sure there are a dozen or more different designs, seems like people are more interested in just shooting the messenger, rather than taking the explanation for what it is worth. Like I tell my kids don't be one of the ten percent.

I wish I had found this video yesterday. I had the "Service Air Bag" message on my 2009 Silverado 1500. Wife needed the truck to go out of town so I didn't want her driving it without the air bag. I suspected the problem was one of the impact sensors on the Rad support but wanted to verify it before spending $100 on a new one. My Actron CP9690 scanner would not read the code even though it was advertised as doing SRS which is why I originally bought this model just in case I ever had a problem. I took it to O'Reilleys and guess what--- they couldn't read it either because they were using the Bosch version (Bosch owns Actron now) of the SAME SCANNER. I just bit the bullet and bought an impact sensor there and luckily that was the problem. After watching your video I realized all I really needed to verify it was a friggin' 1/4 watt resistor which I have drawers full of. DOH !!! Great video. Thanks.

Great video! Also, the airbag computer does nothing until usually 2 or 3 sensors are tripped, so if one fails it doesnt deploy your airbags and cause an accident, this is why some airbag lights will be on for seemingly no reason, because one sensor is tripped (or not functioning at all) but none of the others are

The airbag light is on for about 6 seconds because the system does an internal check at start-up. If the airbag light is on all the time, there is something wrong in the restrain system, airbag, sensor, etc. You need to pull the fault codes from the ECU to know what is not working properly.

This may be true for your particular sensor/ system but is by no means the way they work. That is an inertia type sensor used in early systems. Ever seen airbags deploy when a vehicle is hit but sitting still? Park or drive doesn’t matter, there is no deceleration there. They utilize a potentiometer that measures strike force- impact and signal the control module to deploy the charges in the bags when enough force is detected. Pendulums in the main sensor where the first deployment methods. Now, with a vehicle running you can blow the airbags by impacting the area the area around the sensor or the sensor itself. 40 years here building wrecked cars.

You should add that normally, three frontal sensors are used to send signals to the ECU that triggers the airbags. This type of mechanical sensor is no longer used for automotive applications, now they are all electronically based with some exceptions (venturi tubes in side impact). The ECU generally has one this mechanical sensors inside, to act as a backup system.
@speedkar998 жыл бұрын
+wysiwyg248 Yes I agree. Of course this sensor was from the 90s when things were simple and basic. Now they use accelerometers and MEMS devices to sense impact. My cars ony have 2 frontal sensors though.

Too bad your vehicles has just two sensors, three is a much safer option. Not just from the durability viewpoint, but also with three, the ECU can make more accurate decisions relative to must fire or not fire conditions.
