comfort closure and viper

Hi all,

This is regarding comfort closure feature through viper 5704 remote start on the Acura MDX 2012.
I got a Viper 5704 Remote installed along with SmartStart GPS VSM250. My installer used a iDatalink ADS-AL-CA bypass module.
The remote start and the smartstart is working fine as expected.

However he is trying to make the the Comfort Closure work, and its giving him a hard time. To begin with, my MDX does have the option to roll up/down the window via the door key lock by turning clockwise and counter clockwise respectively.

This is what he has done until now *in his words* Recorded his voice with his permission to post the context on what he did.

"Hardwired the lock wire in the door and the factory alarm in the door, when connected togather the doors lock, but the windows dont roll up, when disconnected and lock using the viper remote the windows roll up, when the lock and the arm are connected the doors lock but the window dont roll up, And when Disconnect the lock wire, ofcourse the doors dont lock but the windows roll up.
Tried a few other congurations such as double dioding the lock arm wire from the alarm remote start, adding a relay to produce more ground, putting the armed wire, umm factory armed wire on the viper armed wire directly and putting the lock on the relay vice-versa still did not work".

Whats the right approach to make the comfort closure work for the Acura MDX 2012 model with Viper 5704 remote start?

Primarily i would like the windows and moonroof to automatically roll up when arming/locking the car, and pull it back down/unroll on demand through the viper remote.

Please guide, is there a guide, wiring diagram, or any help in this matter will be great.

My brand new car is open up from the dashboard and the door panel, something needs to be done soon. :(

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.

The lock wire has to be connected directly in the driver's door. The Comfort Closure feature must be enabled on the Viper system. The MDX expects to see an extended lock signal in order for the windows to close and the same with the unlock wire.

Another option is to connect 2 Aux Output wires, one to the lock and one to the unlock wires in the door and let the idatalink module take care of the locks via data and use the Aux Outputs to control the comfort closure.

As for the sunroof, I don't think the comfort closure will work with that. You may have to get a window module for that to work.

If the installer doesn't know that, he shouldn't be touching your car. Honda/Acura has had comfort closure for years!!

I looked at the wire diagrams and although I haven't done a MDX personally this way, I have done it on other Honda's.

Ok, so the doorlocks are Positive and in the door. So he has to use relays to convert the negative door lock signal from the 5704 to Positive. On the Lock wire coming from the 5704 have him split the Negative signal with Diodes. One of the splits will continue on to trigger his relay and the relay Positive Output would connect to the door lock wire of the MDX. The other split will goto the MDX Arm wire. He will set the the Comfort Closure option on the 5704 to "Comfort Closure 1" That should roll up the windows upon lock automatically.

As for unlock, the unlock wire on the 5704 will go straight to his relay converting his unlock signal to a positive and his relay output will connect to the MDX's unlock wire

As for disarm and window roll down, He will run form the 5704 both the disarm wire and an AUX wire and connect both of them directly to the disarm wire on the MDX. The AUX channel he uses needs to be set for "Validity" if you want to control how far down the window goes. The longer you hold the AUX button the more it rolls down. Or, set the AUX to "Timed" and have him program how long it takes to roll down the window completely into the 5704. Then the windows will roll down fully with just a press of the AUX, no need to hold the button down.

Once wired, Window roll up would work automatically with lock. But for window roll down, you will need to unlock the doors first then hit your AUX button to control the windows.

The 4 wires in the MDX that you need to interface with are:
Power Lock     pink     +     driver door lock switch, green 5 pin plug, pin 4
Power Unlock     red     +     driver door lock switch, green 5 pin plug, pin 3
Factory Alarm Arm     lt. blue (driver door key cylinder)     -     driver door key cylinder switch, white 10 pin plug, pin 9
Factory Alarm Disarm     blue (driver door key cylinder)     -     driver door key cylinder switch, white 10 pin plug, pin 8

Thanks for the helping hand buddy, i am new around here, and i tried the search meathod, and hit upon an truck load of information for various cars. Was having a hard time understanding which information was right for me for the MDX and 5704, hence posted this on the forum. I;ll try to look again, if you see something very relevant, and can share here, i will be happy. :)

Thanks for your replies, any hint and tip will help us here.
I think the installer was a very knowledgable guy and he did a very clean job in installing the remote starter on the MDX. However when asking around Chicago, i was not able to find even one installer who has added comfort closure to the viper. Atleast this guy had some knowledge since he said he has done on couple of older honda;s, but says the new mdx is little different. Even the DEI dealers were not ready to touch the comfort closure feature. :(

Now that the entire dashboard and the door panel is open, i dont have an option but to get help from knowledgable members from here and guide him.
However coming back to the topic..
The installer has hardwired two wires from the viper to the door, thats for sure, I have seen him using relays as well in between and sometimes directly wiring.. I am sure there is a gap and the meathod he must be trying must not be the right one, hence we are trying to understand whats wrong. Cos the windows and sunroof open or close with the viper but if they work the other feature such as locking and unlocking of the door does not work.. or vice versa..

Please help me find the a guide on this subject from the archive.. any thing will help for now.

Flobee4, wow thanks so much mate, your reply will definately help us in a big way.. i am taking printouts of your replies and taking it to him.
Also, is this the comprehensive meathod, is anything missed out in your post above?

Nothing is left out except the basics, which I'm assuming your installer knows how to wire a relay to convert a negative door lock to a Positive. I'm also assuming he know how to split an output using diodes. If he doesn't know the basics then.... I don't want to finish that sentence..

If you are using a Idatalink module you can still use the door lock inputs on the module. You may have to go to the settings on the website and turn off factory arm and factory disarm on the module.

After that you split the green(lock), blue (lock wire) with diodes and run them inside the door to the factory cylinder wires.

To open the windows you must also wire a aux wire off the alarm directly to the factory disarm wire in the door as well

Nice Enice. On Honda's if I know I'm doing comfort closure, I don't spring for the cost of a idatalink CA module. I use a xpresskit PKH34 or a Idatalink TB or HA transponder only bypass. Since I'm running the wires into the door, I hardwire everything. It's good to know that works using a CA module as you described it above.

Hondas are a bit different then other comfort closing vehicles because an extended pulse on the "LOCK" wire will not raise the windows. In fact, an extended pulse on disarm won't raise the windows, either.

To raise the windows with the key you need to turn the key in the drivers door to the "LOCK" position, release it, then turn and HOLD the key in the "LOCK" position. Without the first pulse the extended (-) trigger on the disarm wire won't do anything (you can simulate this with your key in the door - hold it to the "LOCK" position without pulsing it first, the windows won't do anything).

The first pulse can be extremely quick, but it needs to be there. What many people have successfully done is wire the "LOCK" wire to the "DISARM" wire (through diodes) and then wire an AUX to the "DISARM" wire. When you want the windows to raise you lock the door then hold the AUX until the windows are all the way up. Alternatively you can enable the comfort closure and then then hit AUX first (for the quick pulse) followed by an arm command which should extend the triggers on the disarm wire and raise the windows.

Thanks for your reponse Kevin, so you agree flobee4's meathod posted in the first page of this thread is the correct meathod, as i am keeping this as the definative guide on correcting all the mistakes with my Acura MDX for comfort Closure.. right?

yes, the arm/disarm wires are actually the wires attached to the driver's side key cylinder. The programming of the 5704 to "comfort Closure 1" will upon locking the doors - pulse the key cylinder arm wire once and then it will activate again for 20sec. to roll up the windows. so as you can see the 5704 when set properly will duplicate a person turning the key once and then turning the key a second time and holding the key turned.

If you have to press once for locks, then press again for comfort closure, option 1 would not be correct. It's stated in the manual for the 5704.

Comfort Closure 1: the door lock pulse (or 2nd pulse for double pulses) will remain on for 20 seconds.

Comfort Closure 2: 800mS following the end of the door lock pulse (or 2nd pulse for double pulses); the door lock output will turn on again for 20 seconds.

ha, I didn't find the 5704 manual in the download section of this site, only a quick reference guide. So, I was using a 533P manual. On the 533P its the opposite, I just checked it again. This surprises me... Usually what menu options do are very similar across the line. Good catch shortcircuit161, thanks for looking into that!

Yeah, go figure. DEI would reverse things to confuse us! hehe

My remote starter wanted me to update you guys on what he was trying to do the other day. He wanted me to post this for you to read and see whats wrong.

"Thanks for the info. The negative arm/lock wire is double dioded, going to a relay in the door for lock and directly to the arm wire. Now, when the lock wire is connected, the doors lock and the factory alarm arms but, the windows do not go up. Actually, when both wires are connected the windows do not go up with the key turned in the door key cylinder. I can lock the doors with factory remote and then press arm on the alarm and the windows will comfort close. When the lock wire is disconnected, the doors do not lock but, the windows do go up with comfort closure. By the way, I did not hook up the unlock wire in the drivers door as I spent so much time working several combinations to just get the lock/arm/comfort closure to work."

Please pay attention to the part where he says that he did not hook up the unlock wire in the drivers door... is that the missing link??Thanks for the info. The negative arm/lock wire is double dioded, going to a relay in the door for lock and directly to the arm wire. Now, when the lock wire is connected, the doors lock and the factory alarm arms but, the windows do not go up. Actually, when both wires are connected the windows do not go up with the key turned in the door key cylinder. I can lock the doors with factory remote and then press arm on the alarm and the windows will comfort close.

By the way, I did not hook up the unlock wire in the drivers door as I spent so much time working several combinations to just get the lock/arm/comfort closure to work.

it is supposed to be just the lock wire from the 5704 not the arm wire too. Also, I would have him check the diodes because he states that with both wires connected that the windows will no longer roll up using the key in the door lock cylinder.

If all that checks out. I would try 2 ore options. First what Enice said in an earlier post. Use 2 diodes(verified good diodes) and split the lock wire coming from the 5704 connect one wire directly to the CA module and the other to the arm wire in the drivers door. No relay needed if he tries this way.

The other way I was thinking is hook the lock wire directly to the arm wire in the drivers door and the arm wire from the 5704 to the relay that is outputting the positive to the door lock wire in the drivers door.

Honestly.. this should be very straight forward. It should work without a problem. Like stated earlier... just use the blue and green lock and unlock wires. No need for the arm/disarm wires.

Also, comfort closure on the viper will pulse the blue wire and then pulse again and holds. For the windows to vent you press unlock and then hold on the aux button and it will roll down while you hold the button. Simple stuff bro lol..

Very detailed info!

I give up on my previous installer. Finally found a sensible Viper dealer who claims to have installed several comfort closure feature in MDX's. He is offering to add this feature for me for 100 bucks. (Still not a bad deal), after paying 275 dollars for basic install.
Well, he even promised to add a few more functions to the remote start such as opening the garage door with the viper remote... defrost as well. I will keep the info on this post handy, just in case if we are lost. Will update back today evening.
By the way, has anyone ever added Garage door opener to their viper remote start, I have a garage door opening feature through the car's inbuilt switches.

HI

i'm new to the fourm... have been a lurker for quite sometime...I just finishing installing comfort close function/feature on my Viper 5901... 2010 MDX.. I use the info posted earlier in this thread.

Long story short.... I open up the door panel... tap a wire into the Factory alarm arm Wire (Light Blue (-)) on the key lock harness..... put a diodes and tap the other end to the Light green Lock (-) output wire.. only one wire needed..... everything else is control by Idatalink (lock / unlock etc).

Once i enable the function on the brain window will roll up once i arm viper alarm.

I didn't bother adding the roll down fuction because i won't be using it....

Hi I have a 2010 mdx and tried hooking this up like you said from the green lock to the light blue wire in the door and can't get it to work. I tried the diode in both directions and comfort closure on both settings is there something I am missing
