    I have a 2013 Tacoma. I have tested the relay and fuse. I also tried turning the steering wheel to see if it was the clock spring but I got nothing. The horn works with the alarm. Dose anyone know what else it could be?

    Backprobe Connector S8 Pin 8 (Green/Red) at the clockspring, test light connected to ground touch your backprobe. If the horn honks you have a bad clockspring, if it doesn't you have a broken wire between the clockspring and the Horn Relay.

    @Dm93, or anyone else.
    I’ve had my airbag light come on occasionally, but not always.
    I’ve noticed it come when I hit the horn and then stays on.
    Would there be a quick test like this for the airbag warning light?
    I changed my clockspring last year with a cheap one on Amazon when my horn went out.

    Need to see what codes you have in the SRS module, if they are for the driver's airbag it's probably another failed clockspring.

    As far as circuit integrity testing on SRS systems if it's a hard fault for a specific squib circuit I usually put a 2 ohm resistor in place of a suspect squib and verify the code goes inactive.
