Alarm, panic, and lock beep all silent
Hello, I just got a 2013 Honda fit this past week. The car has been mostly great and I'm really enjoying it. However, I noticed since I got it that although the remote works for locking the doors, when I click lock a second time, it doesn't beep like it's supposed to. At first, I thought it was in valet mode, but holding down both buttons does nothing. then I thought it was the hood latch sensor, and read that unplugging this should make it beep if that is the issue but unplugging it didn't work. I set off the alarm by locking the car from inside and getting out, and only the lights blink. It is silent. What do I check next? Thanks in advance!

Correct me if I'm wrong but I just realized that the hood latch sensor couldn't be the issue because that would only affect the lock beep, but the alarm isn't making noise either

Update: was checking the relay for the lock/alarm horn and found this.. don't know where it leads yet

I assume you're talking about the factory alarm, not aftermarket...
Does the horn work at all? (from the steering wheel) |

Yes, the horn works, but the horn for the lock and alarm are a separate horn. now that I have looked at the alarm horn relay, it appears that something was done after market because there is a wire taped to the relay. Swapping the relay with one from the AC clutch did not do anything
Did you test the alarm horn, does it work? Wiring okay? (all the way to the underdash fuse box, because the wiring diagram makes it look like the control and relay for the alarm horn is built into the MICU inside that fuse box) |

Poo, I forgot they are separate on those cars LOL

According to the wiring diagram I saw, the horn relay in the engine compartment is not for the alarm horn
Horn must be securely bolted because that is its ground circuit....rust and paint can cause problems Make sure you're not checking the wrong horn Can you swap the horns? Are both wire connectors the same? or Use a jumper wire to power the horn by itself then if necessary Continuity tests (or suitable dynamic testing) the wiring from MICU to horn I wonder if a dealer level scanner would be able to reveal any helpful info |

I am getting no voltage going to the alarm horn with a good relay swapped out for the one that has a wire connected, so I think whatever is going on here will be too complicated to diagnose over the internet.
