1989 Honda Accord

Hi,

Over the past year I have had some ongoing trouble with my Honda. This
problem happens during driving, when the vehicle is off, even when the
keys aren't in the ignition and the lights are off. The problem is
that there is a buzzer, more of a high pitched alarm that sounds and
stays on. The problem comes on and off randomly, and there doesn't
seem to be any reason for it. Also, the chime, that is supposed to
ring when the lights are left on, sometimes rings once right before it
happens, and once after. For example... Ding, High pitched ring (stays
on for a random amount of time) ding, and then it's all off. Also with
the alarm, the seatbelt and brake light on the dash will come on and
stay on till the alarm goes off.

I found out that the alarm is coming from the integrated control unit,
but I still can't figure out why. Also, so far the only way I have
found to make it shut off is to unplug the wiring harness form the
back of the ICU and then plug it back in.

Any ideas?

Pull the ICU and inspect it for corroded/leaking capacitors. This is common
on some models of ICU.

Also inspect the ICU for corrosion that may have developed from water
coming in through rust in the cowl.

You may be able to find a replacement ICU cheaply from a wrecked Accord.
Visit your local wreckers.

 

i second the replacement approach. if your accord is a wagon with rear
wash/wipe, you'll need one for the same type of vehicle, but other than
that you should be ok. cheap from a wreckers yard. easy to do.
