Honda Car Forum

Greetings!

I've weird problem with my Acura's security alarm from last few weeks
(I know alarm was working fine a month ago). When ever the alarm goes
off, it blows up the 20amp "Stop Horn" fuse under the hood right away
and car doesn't start after that. Yesterday, I figured out a way to
start the car atleast. I plugged in a 25amps fuse in place of 20apms
"Stop Horn" fuse, but as I plugged it in, the Relay near the fuse
started making ticking noise and car started honking. I unplugged the
horn, but the ticking noise was still there. Then I pressed the door
unlock//lock key on remote, which turned off the alarm system.

But problem is still there. If security alarm goes off in future,
it'll blow up the fuse, and I've to do the whole thing again. Can
anyone please suggest any possible solution to solve this problem or
how can I just disable the security system. I help will be much
appreciated.

Does the fuse blow if you activate the horn normally with the steering
wheel buttons? If not, then it's likely that the Horn Relay Control is bad
which is inside the Security Control Unit. The SCU is under the dash
somewhere. I don't know exactly where on your car.

You can disable the security system by grounding the correct wire on the
trunk latch switch connector (the easiest switch to get to). The system
will only arm once it knows that all the doors, hood and trunk are closed
and locked. With that wire grounded, it thinks the trunk is still open and
will not arm itself.

It sounds like a bad horn to me. The ticking sound you hear is the lighting
relay flashing the lights. Normal condition while the alarm is activated.
Try honking the horn with the right fuse in the fuse box to see if it blows
again. If so bingo bad horn.

I should have completed this post: If the 20A fuse DOES blow when you push
the steering wheel button to sound the horn, then David Short is
undoubtedly correct. The horns are behind the front bumper and can short
out due to corrosion and damage.

A final word: *NEVER* subsitute a higher-rated fuse in a circuit that keeps
blowing the correct one. That's an excellent way to risk setting your car
on fire.
