Airbags and sensors, question Options

[MaskedMan]

I was just wondering how the airbag sensors on our Celicas operate. I've read up about different types of sensors, but I'm not sure which kind were used on our cars. Also, if the airbags were to deploy and the vehicle were to be repaired, is it nessecary to replace the airbag ECU as well or will it be alright to reuse the airbag ECU?

One more thing. What is the easiet way to remove the passenger side airbag? Is it required to remove the dash or is it accessable by removing the glove box?

Thank you.

Thanks for the help all of you . I will go ahead and replace the Airbag ECU while I'm at it. I would hate for my airbags to malfunction just because I wanted to cheap out and not replace the ECU as well.

One more question though. What is the proper way to test an Airbag sensor? Is there a way? Because I am purchasing airbag sensors off a member here, and I want to be sure that they are still operational after they are shipped (you know how rough shipping can be). Oh and, the links had a lot of good information, but does anybody know how many airbag sensors our Celicas have? I just need to know so that I can replace each one that may be damaged. The Celica was involved in a front end collision on the passenger side of the car, causing the airbags to deploy. I see there is an airbag sensor right there next to the radiator. That one I am going to replace, along with the one of the driver side as well, just to be safe. Are there any other sensors that I'm missing and/or should replace?

LOL....crash it!

I think you can test it by taking out the signal wires that goes to the ECU or airbag and put a voltmeter across those wires. Now take the sensor(s) in ur hand and quickly swing ur hand to the wall, the sudden stop should act as an impact and if you see the voltmeter registers a current/voltage then the sensor is working.

But I dont know if you can resuse them once you try them out.

Not recommended though.

I always thought the sensors were one time use only. The more I think about it, the more complicated and in depth my questions become haha. Also, swinging my hand into the wall doesn't seem like a valid test . Actually I get what you mean, it could possibly show that the sensors will operate if that were to happen, but I'm almost positive I would have to buy new sensors after that test haha.
