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.

I was just looking in the BGB and it seems like the only real way to test the sensors is to install them in the car and check if there are any airbag DTC's

maybe you could do some of the tests for when it says the sensor is bad but those seem to also involve testing while connected to the harness.

it does list Replacement Requirements for the center airbag assembly and sensors as the following:
- If the SRS has been deployed in a collision. (Replace both left and right airbag sensor and center airbag sensor)
- If the airbag sensor has been found to be faulty in troubleshooting.
- If the front and/or center airbag sensor has been dropped.

Also under removal and installation instructions there is a notice reading:
- Never use SRS parts from another vehicle. When replacing parts replace with new parts.
- Never reuse the sensor involved in a collision if the SRS has deployed.
- Never repair a sensor in order to reuse it.

also the front airbag sensor have to be torqued to 22 ft/lbs
