I have an oldish Honda that still runs smoothly. It is true that the cruise control does not work, and the left front fender is held on by a large binder clip, and I had to patch over a big rust hole in a rear wheel well, but as I said, it runs.

I sometimes park it down at the end of the street, under some shade trees, to get it out of the hot summer sun. A couple of times, for no reason, the antitheft system kicked on, so the car was honking and honking for hours on end because we didn’t hear it down there. Some neighbors down there finally figured out who it was and came and told us. They were nice about it, but I heard some other folks down there were pretty irritated.

That happened again two weeks ago, so I decided to keep it in front of our house all the time where we could keep an ear on it. Supposedly the alarm is triggered when the car thinks that a door or the trunk or the front hood has been opened without a legitimate unlocking by a key or a fob. Therefore, I opened and closed all four doors, and the trunk and the hood, and locked the car and hoped all will go well. But a few hours later there it was: honk, honk, honk….

As a temporary measure, I simply left it unlocked, so the system would not arm. But that’s not a long-term fix. So, I rolled up my sleeves and went to the internet to see what help I could find there. One common suggestion was to find the fuse that controls the alarm system and just pull it out of the fuse box. That would be great, but I checked multiple fuse diagrams for my model, and it does not seem to be a fuse that controls just the alarm system.

Other web sites mentioned that day sensor on the front hood latch is a common failure point. The sensor there can start giving spurious signals when it gets old. If you are sure that’s the problem, you can have a garage replace it for labor plus maybe 100 bucks for the replacement latch.

Alternatively, you can just pull apart the connector that connects the hood latch sensor to the alarm system. That connection is in plain sight near the latch. If the latch is the problem, disconnecting that sensor should make the alarm system think the latch is always firmly closed, so it will not trigger an armed system.

But what if the hood latch is not a problem? What if the problem is the common but elusive damage to wiring caused by rodents gnawing on the insulation which contains soybean derivatives??  After sifting through about 10 links that were thrown up by my DuckDuckGo search on the subject, I finally found a useful discussion on the “civicsforum.com”.

A certain “andrickjm” wrote that he had disconnected that wire junction, and his car alarm was still randomly going off. Some savant going by the moniker “ezone” wrote that what you needed to do then is to insert a little wire jumper between the two sockets of the connector that go to the alarm system. That will make the alarm system think the hood is always raised, never closed, and this will keep a system from ever arming.

So I cut a 1-inch piece of wire, stripped the insulation from the two ends, bent it into a U-shape, jammed the two bare wire ends into the two holes in the connector socket, and sealed it all up with duct tape.

The alarm has not sounded since. Victory at last, thanks to the distributed intelligence of the internet, resting on the efforts of millions of good-hearted souls who share their problems and solutions in all areas of life.
