    i don't know what else it can be, if it was installed properly.

    if anything could change trip meter, it would be tech stream

    The problem is your spiral cable/clockspring. You can find them cheap on ebay. I found mine for $10 and now all my buttons work and no more airbag light.

    This is the spiral cable, I got it from ebay and it fixed all issues. You will have to get a free tool rental called a steering wheel puller from autozone. tapatalk_1591635437625.jpeg
