Icon9 electric door locks haunted

Ok, I'ma newbie and have been bouncing around this forum searching all over the place for this problem and can't find even close.

Have a 4th gen -95 prelude that I am trying to DIY back to "normal" operation; it has a wierd problem with the electric door locks in that BOTH locks keep locking and unlocking repeatedly at intermittent intervals while the car is parked (engine off) or in motion. The lock switches work fine, but stuff goes off by itself freaking my daughter out so she wont drive the car.

I wouldnt think it was an actuator since both driver & pass. locks do this in tandem and there is an actuator for each one. There was an aftermarket alarm system installed when I bought it and it was uninstalled by the dealer so might be a problem there. Please don't say its a "short" because I would have no idea how to track that down.

Re: electric door locks haunted

if someone tapped into the factory harness, I'm sure there's some hacking w/ the wiring. it's a PITA to trace that kinda thing down. did you look at the 4th gen resource guide wiring schematics? I'm pretty sure there's a relay in that circuit, it could be causing the problem.

I just re-read your post. it has to be from when they tapped into it for the aftermarket alarm. find where they spliced their wires in, and make sure they're re-wraped w/ electrical tape or shrink wrap. (each wire individually!)

All: DIY Alarm and Remote Start

Quote:
Door Lock/Unlock: Here you go Jesse, this one is for you! :D The Honda Prelude uses a negative "pulse" to lock and unlock your doors. In most manuals this can be VERY confusing. So let me spell it out in prain engrish.
MOST installation Manuals will identify the alarm module wires as:
{Wire Color} (-)Lock (+)Unlock,
{Wire Color} (+)Unlock (-)Lock
To me this was confusing as HELL..... so I went inside, had a cold glass of my favorite beverage, and did some research. For OUR Cars all you need to know is that there, on the right side of our cars, there is a plastic "Frame" containing 4 wiring harnesses; find the gray colored 10 pin on the back right side. Now take your TEST LIGHT and ground the alligator plug to a KNOWN GOOD GROUND and probe the Black/White(-) wire while watching your door locks. Did it move to the unlock position? Now probe the Black/Red(-) wire. Did the doors lock? Mark em as such then put that test Light AWAY! (image7)



Door Lock/Unlock Harness - This plastic block that holds four harness' is the easiest place to get to the lock/unlock controls. The two unplugged harness in front are for the right side of the dash {removed obviously} The harness we are focusing on is the one in the back right closest to the wall. simply reach under and pull the bottom of this A/B plug out. Sorry for the fuzzy picture, but you can kind of see the two wires I pulled out from the bundle. These are the very wires you need to splice into.
(image7)
other than the above.... look for the harness/cut wires as mentioned. It is a short... you ARE going to need to find it. The good news is that if its doing it randomly, there is a Bare copper wire VERY CLOSE to a metal structure under the dash.


Good luck!

Re: electric door locks haunted

Forgot to ask, where can I find the harness shown in the picture. I assume its behind the dash, but which side and is it accessible underneath or what do I need to remove.

thanks

Re: electric door locks haunted

from the picture, that looks to be the passengers side.

yup! :nods:

Remove the glove box and the kick plate and you can get to it from the foot well. That pic was taken when I removed my dash to install the alarm.
