balancerider 702 Report post Posted February 21, 2022 Seems my low tone horn has died - last time I hit it, it was decidedly squeaky. Apparently a known failure mode for these cars. Anyway, would I expect a code to show on OBD app if relay had failed? Guessing the horn wouldn't work at all if it were a fuse. Suppose a multimeter would be able to tell me if circuit to horn was intact. Quote Share this post Link to post Share on other sites
