Default Driver Door lock dont work after new alarm install

I've already post the same thread on RS25 but though I can get additional feed back here.


Here it is:

Me and my brother both own a 00 and 01 2.5 rs Coupe.

He recently installed a new aftermarket alarm into his RS and the driver side door wont lock and unlock anymore from the switch and remote.. The passenger will work with the new alarm remote and with the driver side "lock and unlock" switch. Given it has work before the installation.

At first he tested every wire and were assuming that thedriver side actuator die.
And this weekend I've install an aftermarket alarm of different make into my RS and the same thing happen.

Heres what I did. I first remove the OEM alarm from the car. Tested all the door lock and I notice that my driver side door switch dont work for the driver side door anymore. Just like my brothers car. Than I put back the OEM alarm, and every thing worked fine. We tested out that in the RS, There is 4 different wire that is connected to the OEM alarm module that controls the door lock switch to work with both doors. But we werent able to figure out how to rewire it to work with the new alarm module. Can anyone help me?

I also did some reading on the12voltcom . And they said that there are several types of door lock wiring system that any vehicle can use.

Does anyone know what kind of door lock wiring system does the RS uses?
Single wire system?
3 wire negative?
3 wire positive?
4 wire reversal?
5 wire alternating?
Vacuume type?
does any of this make sense to anyone?

You want to work through the OEM system and let it worry about the specific type of door lock wiring, not you. I think your problem is that when you removed the OEM alarm module, there is probably some sort of "shorting plug" that gets plugged in in place of the module to connect some wires properly (usually, when you install an OEM alarm module, you remove this shorting plug and connect the new alarm module in place of it). I would try to find a '00/'01 Impreza w/o OEM alarm in a junkyard in order to get this shorting plug from it (should only be a couple of dollars). Alternatively, you can check with your dealer on how much it would cost to buy a new shorting plug.
Of course, the best bet is to find someone with a wiring diagram for the '00/'01 so you can figure out if you really need the shorting plug or can just make a few connections yourself to fix the problem.

I thought about making a new post but why. Ill just bring this back from the dead. Has anyone figured out how to get the driver door to lock and unlock if you remove the factory security module?


On a side note, does anyone know if this causes your radio to stay on 30 seconds after the key is removed? It is the ONLY thing done which could cause this, however I dont know why the OEM alarm would affect it like that.


I have a 99 2.5RS and the above post is word for word what I would have typed.

Can't you just hardwire a switch into the locking actuator? Did it on a 91 240SX after the driver side actuator went bad and we replaced it. For fun of course

Is the radio OEM? I know that the 02+ radios shut off with the car (past ACC), but I know little of Pre-02 systems.

No, the radio is aftermarket (Eclipse). I disconnected the radio and the problem doesnt go away, as in the Accessory power still shows power after the key is removed.

Someone suggested that maybe this is a programable feature which might be able to be turned off with a sequence of key turns. Does anyone know of this? Any Subaru techs on this board?

you have to jump two wires in the oem alarm module wiring. i had to do this for a coustomer the other day. the reason that it doesnt work both doors is that the factory keyless/alarm has driver priority unlock. test for the wires and just make a jumper. then your aftermarket system will work fine.

Is it a white plug with roughly 16 pins? Im just going off of memory. I will try and take a pic soon to make sure its the same one. Test the wire for the drivers door lock and for the passenger door lock and add a jumper inbetween?

when you test plug the module back in. there will be two a few wires that test like they would be door lock wires. then unplug the module and find the wires that get the signal and that dont. there will be one wire not getting the signal with the module unplugged. this is the output wire to the drivers door module. jup this to the wire still getting the signal and your done.

I don't understand why you're trying to pull the factory alarm.... you're just making this harder that it really needs to be. The guy who mentioned driver's side priority unlock is right. Leave the factory piece in place. Door lock type is simple, it's just negative triggers. Just splice your triggers into the factory wiring and that should be that.

Power Lock blue/green -trigger keyless module
Power Unlock yellow/red -trigger keyless module

Directech says go straight to the keyless/alarm module for the wires.

BTW if you are worried about the factory alarm arming, there's a red/green wire at the door lock timer, should be just a negative pulse to disarm the alarm.....

The door lock timer is up high above the drivers kick panel. It has a 6 pin plug.

There are two seperate trigger wires for your door locks. One operates the drivers door the other unlocks the other three. For my '05 RS it was RED for drivers door, RED/GREEN for the other three. It is a negative pulse to activate. I wired my oem to pop my trunk on the second push.

See my write up here....

It seems like you tapped into the "other" trigger wire that is linked to your other three doors, if you trace it back to the wiring harness, it's right next to it. Should be able to jump both wires together and your current wiring should work.

That being the case, shouldn't you diode isolate em to keep the factory alarm functionality?

I dont really want the factory alarm module in there. Its pointless when adding an aftermarket. I dont mind jumping two wires together if thats what needs to be done. Ill try it out and see what happens. However if plugging the factory alarm back in solves the annoying radio problem then Ill be inclined to keep it installed.

The oem alarm might have a relay in there to work the door locks. You might have to leave the factory alarm in there. Is it a alarm or just keyless? IMO if it doesn't false the aftermarket alarm, leave the oem module in there or else you might burn it out.
