My SRS light came on which is a warning about the airbag system. Found this post on how to reset it but it wouldn’t reset. I had made a jig with wires soldered to a toggle switch to make it easier to perform the procedure.
I plugged in my OBD sensor and it didn’t display any fault codes. I found this post which allowed me to read the fault code of 9-3 by jumpering two OBD connections. The fault code indicated a faulty driver’s side belt buckle switch.
This video shows the complete procedure to fix it on a civic. My torx screws are the style that have a pin in the middle and I didn’t have the correct bit to remove it. My switch appeared to be working observing the seat belt indicator on the dash so I sprayed some air inside the buckle to help clear it. I then repeated the original procedure to clear the error and it finally cleared.
