My 96 3.2 TL-P locks keeps locking randomly, it does it whenever, where ever. How can I fix this. TIA!

 

i thought i was the only one going thru that

 

Same here, lol..

 

This is a common problem on Honda/Acura door locks. The problem is a ground-release switch in the door lock solenoid causing a bounce that results in the repeated cycling of the door lock. If you do a google search you may be able to find some info on fixing the door lock solenoid. It's probably of interest to only the more determined Diy'rs. Easier and more common fix is to replace the solenoid w/ a used unit from a salvage yard. Problem is the door panel must be removed and some fairly tedious blind removal/installation work to replace the defective solenoid assy. Part doesn't show up on car-part.com, probably because of access issue to recover the part.

good luck

 

crap, anymore ideas anybody else?

 

TexasHonda - do you know which door has the solenoid with the problem? Is it possible to bypass the problem by cutting the wires that go to that solenoid? I don't use the power locks that much and wouldn't mind losing the functionality for one of the front seat locks. I think I need to be able to use the power unlock option to unlock the back doors, but can use the key or reach across the seat for the front locks.

 

The door w/ the cycling solenoid is the place to disconnect. You will have to remove the door panel to access the connector.

good luck

 

TexasHonda - thanks for the reply. I'm not sure which solenoid it is, but will have to listen carefully and see if I can find it. When I cut the wire, I don't plan to cut them at the solenoid. Instead, I'll use my service manuals to find the wire color and cut it at the harness going between the body and door. I hope I succeed.

 

You'll damage your wiring harness cover at the door, and you may get the wrong wire. It only takes about 15 minutes to remove the door panel. After that access to the connector should be easy. I think there are several posts about removing the door panel around.

good luck

 

ha thought i wuz the only 1 with that problem it drives me crazy

 

I've posted twice on the matter now. Search for one of my older posts where I gave advice to another member regarding this problem. Highly common in mid 90s Honda/Acura products for the reasons TexasHonda mentioned. I found a solution to it, which I posted here. It worked on a friend's car. Cliffnotes are as follows:

1. Take door panel off.
2. Find a blue/white wire that runs to the soleneid. It should be near the latch area.
3. Ground it. I sanded of a small portion of the inner portion of the door, stripped a small area of wire, and then looped it around a bolt and bolted it to the door. Ghetto, but whatever works.
4. Solenoid should work fine after that.

Cheers Let me know how it works for you guys.

 

well hate to bump this old thread... but im hoping i can fix this before all my actuators fry. I pulled the driver door apart and tired the grounding thing, but it didn't work. Everytime it was grounded, the locks would lock. if you unlocked it using the switch, it would relock. I unplugged the harness to the driver actuator and locked the car. The car began to do the click click click thing again, except all the doors would lock besides the driver door because it was unplugged. I'm out of ideas, something is constantly sending a signal to the switch to lock.

 

Maybe a new security module is in order. Didn't think about that until now... It could be that the brain is repeatedly sending the lock signal until you press unlock since it's not getting feedback from the doors telling it that the lock cycle is complete.

~Cheers~

 

but still, it still keeps locking if you use the switch. So i think its the module that sends the signal to all the doors to lock.

 

When you lock manually, the security system still arms, so that module *must* have something to do with it, I think.

~Cheers~

 

blah... any more ideas?

 

My idea is to do nothing about the trigger happy door locks - let them fail so long as the battery isn't killed in the process. I've had the problem for several years without a battery failure - so I think I'm ok ,

Howerver, I'm sick of the alarm system arming and triggering itself every time I leave the car unlocked for a few minutes I'm ready to disconnect the horns (since I know how to do that), but I'd rather disconnect the alarm system. How can I do that?.

 

another doorlock problem.....my back rightside door makes a loud BUZZING sound everytime i lock it and its annoying anyone know what this is or had this prob. before

 

I had it on my back left, so did deadsetonliving. I just disconnected it, he went and bought an aftermarket actuator to fix it.

~Cheers~

 

There are two options; replace/repair the lock/unlock solenoid assy or disconnect the assy. If you don't think you want to try removal, then disconnect is only option.

good luck

 

Im having the same problems too and it is draining my batteries... I disable my alarm and that did not fix it. So the only way to get this fix is to disable this solenoid thingy. If I do that would I still be able to unlock the other locks with my key or the switch inside the car?


@Bluish if want to disable the alarm it is easy, there is a plug that you pull to do so. I'll try to find a picture of it and get back to you ASAP.

 

FYI - I finally got around to implementing the fix, soldered a wire in there and made a good solid connection to ground with a lug.

It still locks. I used the schematic/wiring diagram to get what I thought was the right wire. It was a wire that the system used to get feedback from the solenoid to confirm that the doors were locked. In the drivers door, there is a contact in the lock mechanism that provides feedback - figured the problem was there.

Bottom line - I still have the problem.

 

same, no matter what pattern you close and lock the doors in it still does it. ugh. I wonder if theres a way to make the alarm think the door is still open so it doesn't arm but the door is still lockable.

 

Does anyone know how to completely disable it, where I would only use the key to open my car?

 

I really wouldn't mind doing that either^

 

It just seems to be random. If I get out of the car, close the door and wait about a minute - I'll hear it lock itself - other times not.

So, I always try to remember to take the key our or roll the window down when filling up!

 

wait, yours does it even w/o the alarm armed?

 

Yep. Well at least I guess so. I'd have to go back to the owners manual and see how the alarm is armed. Here are the typical situations I get:

- Turn car off, take key out, get out, leave doors unlocked, shut door. Fill up, or walk away without locking or hitting the lock button on the remote.
----- About 30 seconds to 3 minutes later - Click - all doors LOCK


- Last night, the other sequence happened:

-Drove home, Turn car off, take key out, get out, leave doors unlocked (or did I lock them...???), shut door.

--- 3 minutes later - the alarm starts going off.

Pain.

Sometimes it goes a while where it does not act up. Basically it has a mind of its own. I'll have to check the owners manual, and the schematic. I was thinking last night about bypassing the alarm system and going back to just door locks which are not integrated to any alarm...

 

You can easily disable the alarm if you want ill post the screen shot of someone who posted where the alarm is here...

But anywho, how do you disable the automatic doors!!!?

 

Screenshot would be appreciated.

So, I guess that I have two independent issues going on:

-Alarm going off when unarmed
-Door Locks locking whenever the heck they want.

I have the factory schematic, will have to take some time and check this out further. I'll get to it right after getting my 540i back on the road, fixing my quad, 50 things around the garage, finish some maintenance items on my Navigator (rear pinion seal).....

 

From the Factory Electrical Troubleshooting Manual for the 97 3.2 TL:

"...The doors will relock automatically after 20 seconds if a door is not opened or the key is not in the ignition switch. The remoter transmitter will not lock the doors if the key is in the ignition switch."

So, maybe the mysterious locking is built into the design. Will have to test this out further. SO, if you take the key out at a fillup, make sure you take it with you and don't leave it on the console.

Have to check into the alarm going off occasionally, there are a few conditions that may have occurred in the past that have set off the alarm. Weird thing is that there was a delay. For example, if the window is open, doors locked, alarm set - if you reach down and open the trunk with the release - the alarm will sound, lights flash, etc...

 

I disabled them for now because I didn't want it to keep locking and locking. I pulled the 18 pin connector. The one with the gray plug right behind the glove box. Now I pretty much don't have alarm or power door locks, gotta manually lock and unlock each door.

 

Me too i just posted a thread thinking i was the only one. lol. but it is terrible it does all the time non stop. i just turn the radio up. Do you think this maybe hte reason why the factory alarm goes off?

 

MYs ame door has this problem!! oh wow

 

does yours keep locking and locking? does 1 door always try to lock?

 

One night this week, I'll get the schematic out and see if there is a way that we can:

- Remove the alarm from the door lock circuit
- Disable the alarm

 

All the doors. But its not the car alarm though. That was already tested. even when I lock the car and walk away I hear the locks locking..wtf?

 

yea, exactly, the doors keep locking and locking.... now mine doesnt do that or have power door locks. unplugged FTW!

 

So I was thinking, what if I put a switch on the lock wire of the plug leading to the module. Then I can flip the switch on to use the power door locks and to keep them from continuing to lock, I can flip the switch off.

 

I just found this post and I am having the same problem.
When the car is locked and you unlck it with the remote, it is supposed to relock after a few seconds go by if the door is not opened.
I think the problem is that the car doesnt realized that the drivers door has been opened- meaning you unlock with the remote, get in, car doesnt realize door was opened, relocks ans sets alarm. (I've tested and it doesnt relock when you open the passenger door).
Seems like maybe a bad sensor somewhere.
I always keep my keys on me now so I dont get locked out!
FYI if you hit the unlock button when the alarm goes off, it stops the alarm (at least on my TL)...
