You have the wrong unlock wire then. You are probably tapping into a motor wire for the door lock, this will not work. You need to find the switched wire

 

all other alarm functions work except for the unlock door. I tried all the suggested colors on the driver side kickpanel and tapped all the wires-what color is it? evo9? I am using a diode each in both lock and unlock wires of the alarm

 

Why?

There is no reason to. The alarm can output a negitive trigger and the switch from the door is a negative trigger.

There is no reason to use a diode for door locks. I have done quite a bit of alarm installs in evo's and never used one, like never.

I forget what color the wire is, it has been well over a year since I quit doing installs, but blue/black stripe come to mind for some reason.

What are you using for a test light or meter?

 

The info that I have shows it being a light green color. It was that color in my car.

 

That sounds right. The Evo 7 I did a alarm install on had blue lock/unlock wires.

Still, always verify with a DVM or circuit safe test light.

 

+1. My lock wire was a different color than what my sheet had. The suspect wire should rest at 12v and drop to 0 when you hold down the unlock button, then go back to 12v when you let go.

 

Won't the alarm still see a door as opening preventing the remote start from activating (if he disarms before RS activating DLS)? That was my reasoning for the diode was so that the doors were always isolated from the DLS wire so he could RS whenever he wanted to and it would prevent the alarm from seeing false door openings while keeping full door trigger protection. Isn't the purpose of the relay to prevent running domelight current through the alarm DLS wire which is only 250ma (vs 30-40a for a relay)?

This is what I told him to do. http://i249.photobucket.com/albums/g...sr/alarm-1.gif (the individual grounds represent the doors)

But he should use a relay instead of hooking DLS straight to the door trigger

 

I can't see your picture at work.

But I suppose if the RS will not work if the door is open. Mine does not operate like that so I can not comment.

But I would think that you would RS before disarm anyway, like if you were in the house before you left, you would not unlock your doors before you were out to the car.

But you could use a 2nd relay on the door trigger input to the alarm if needed to interupt the signal to the alarm and the alarm would not know the door was open while DLS was engaged.

That way there you could do disarm (relay turns on interupting input to alarm from DLS) then RS. Once you got into the car and shut down the RS with key takeover the relay would shut off and security would be back to normal.

 

Yeah, the reservation mode RS won't allow you to open a door after you set the sequence or it won't start.

I would also think you'd start it before disarm.

Basically the drawing has the DLS wire tapped to the door trigger, a diode downstream on the door trigger with the line facing away from DLS, then tapping the alarm door trigger downstream of the diode, therefore when DLS grounds, the alarm door trigger doesn't see it, but it still sees all the doors.

Hopefully you get the idea. I don't see a reason why it wouldn't work. Maybe you can. And it's a bit easier than wiring any extra relays. I personally avoid relays whenever I can. I don't know why, but I hate wiring relays.

 

the diagram says, violet lock which I connected to my lock trigger wire in my alarm. I tried using the light green for the unlock but it will not work. tried reversing the diode to no avail. I use a multimeter gauge.

 

Take the diode OUT! There is no reason for it at all. What kind of alarm is it? What did the multimeter do when you tested it? Is this wire in the same harness as the lock wire?

 

the OP is compustar, so it is the 2w900fmr(3000). the lock is at 0 then pulses to 12v when you hit the lock button, so it works. for the unlock, it starts at 0 then goes -12v pulse. the wire is not in the same harness as the lock wire. since I tried that light green wire near the lock wire but it will not work. it has been 2 years, so I will try to look at it if I get the time. but everything else works, remote start, turbo timer, perimeter sensor, tilt and motion detector, shock sensor etc. car will not start manually unless you press the clutch, but will start on RS mode(used a clutch relay).

 

This is an Evo? Where did you test these wires? The lock wire that works, where did you get that wire?

 

06 evo9 MR brand new when I installed it myself. tested the wires at the DKP. like I said it has been awhile and works fine except for the obvious door unlock trigger. I will try to find it again when I get the time I was actually the one who found where the tach wire is in the dash for the evo9. different colors from evo8's

 

are you suggesting that the door lock and unlock wire is only one wire? that is what I initially thought that is why I used two diodes in opposite directions to trigger the lock and unlock button. but it did not work. what color is the door unlock wire then?
