My alarm kept going off last winter. After some googling I found that Honda hood latch sensors have a tendency to fail. I removed the sensor, packed the connector with silicone grease and wrapped it in electrical tape. The sensor sees the hood as "closed" when the circuit is open so unplugging the sensor permanently opens the circuit. No issues since.

 

 

kyle if you are still here , did this fix work 100% ?

 

I had to reset my password to get in but I'm still around. My alarm has not gone off since. The issue was 100% a failed hood latch sensor.

 

Thanks, mine has been good since I unhooked it

 

Seeing this issue too. Rather than try to fix my hood or hatch connections (no idea where to look, or what I'd be looking for), I think it would be easier for me just to remove a breaker. Does anyone know which one would control the alarm system? Or maybe I can't do this for security reasons?

 

The quick answer is to disconnect the horn behind the driver's side headlight. It does not sound when you press the horn, that's a separate horn. If you'll give me a few moments I'll find the method to access the latch on the hood in the service manual.

EDIT: I'm attaching the page for removing the top of the grill and the guide to remove the hood latch. If you need more or something different let me know.

 

Its probably been said already but rip out the hood latch sensor.. Red 05 has the right idea.

I did that and it fixed my problems
