Default What does this do?



I was finally motivated to remove the beeper from my car. I used a process of trial and elimination by unplugging modules one by one. This is the only one that resulted in stopping the beeping, but I am concerned that it does other things. I put it back in already just in case.

Besides the obvious?

Removing it creates an open circuit in the seatbelt sensing mechanism. The adaptive airbag system then assumes the driver is unbelted. This will change the airbag deployment configuration so as to minimize unbelted occupant injury during deployment.

Well, it obviously times the seat belt for something... seriously? Would I have really gone through the trouble of walking back inside, taking a picture of the thing, uploading it, and starting a thread if I knew what it did?

I'm not a genius, that's why I'm here learning.

There is no connection between the seat belts and airbags on a 97.

You should have no problem with removing the module, but it would most likely be neater to unplug B74 which is the plug for the key warning switch itself. It's a black 2-pole plug on the steering column with one white and one yellow/black wire.

That will kill the key warning buzzer without affecting the seat belt light. If you want to kill that whole system just pull the module.

^^ agreed with Dan. the SRS system in the late 90s cars is not related to the seat belts.

My car doesn't chime at all, nor is the light lit - however my seatbelt anchors are not plugged into the harness.

Great information, Dan ! Thanks for posting it.

Perhaps this should be added to the FAQ section ?

I think I'd just alter the sensor at the actual seatbelt harness, like huffer did...

It's a TIMER. It bleeps until you plug in the seatbelt. If it doesn't register a sensor (like a seatbelt buckle) it won't bleep.
