Subject: 06 Altima Python881 trunk pop problem

Here is the run down: 06 Altima with a Python 881xp just installed. I had 2 main problems which one of was fixed but right now I can't pop my trunk without unlocking the doors first. But here is the wierd part: Once I unlock my doors I can pop my trunk open and then if I close the trunk and then lock and arm the car, I can still pop my trunk open with the car in its armed and locked state. But once I start and stop the car engine, get out, lock and arm the car, I no longer can pop my trunk anymore wthout having to unlock and disarm the car, but once I do that, I can pop my trunk even if the car is armed until the next cycle of starting and stopping the car engine. I called up my installer and he told me that this is just a design flaw and nothing can be done about it, is he right or am I being bulldoodieted? Please help.

Does your car have factory trunk pop? and he is using that?
If so, some cars doorlock switch, and other switches die after the car is turnt off. And that you have to "wake it up" again. (im not even sure if your follows this trend)
IF it was an aftermarket trunk popper, you should be able to trunk pop anytime you want.

There may be a keysense wire that needs to be pulsed in addition to the trunk pop wire...

My car does have factory trunk pop on the OEM key fob, I just need to have confirmation if it can be done on an 06 Altima so I can go back to him and tell him for sure.

here's what i come up with:
Trunk/Hatch Release RED / black or blue/red - BCM to right of fuse box, pin 30

Strange. I've never had that problem on any of the dozen or so 05-06 altimas I've done. Have the installer make sure the factory alarm is set to be disarmed with the trunk release. I beleive it's menu 2 option 9. That is assuming that the factory alarm disarm wire is even hooked up.

Hymer kind a hit it. He was looking at the Astrochart like me.  You'll need 2 relays Relay 1) neg trunk output to pin 85. 12V, to pins 86, and 87, pin 30 goes to the trunk pop wire PINK. Jump off of the NEG(-) trunk output and install a diode, cathode end towards your remote start . Relay 2) AFTER the diode, take this wire to pins 86, and 87 .12v to 85. break the trunk pin wire ECM side to pin 87a, trunk side to pin 30 PURPLE / white. This will pop the trunk without disarming. -------------

That is how Nissans (and many other cars) are from the factory----the trunk pop doesn't work while the factory alarm is armed.
When you lock the doors with your 881, (or with the Altima remote, for that matter), the factory alarm doesn't arm for 30 seconds.
Observe the red light on the car's dash.......when you lock the car, it stays on steady for a period of time, then starts to flash---the alarm is armed when it starts flashing.
If you lock the doors (which starts arming the alarm), you can still open the trunk within the next 30 seconds, but not after.
I just tell customers that the car must be unlocked before the trunk can be opened, and they are generally happy with that.
There are always ways around such things, but are you willing to pay for it, or is your installer willing to do the extra work for free?
Two possible solutions:
1. Split the Python's trunk-pop output with two diodes. Connect one diode to the car's trunk-relase wire which comes from the switch.......connect the other to the car's factory-alarm-disarm wire.
That might or might not work.......the disarm and the trunk-pop wire are going to be seeing the signal at the exact same time......it's possible that the alarm needs to be disarmed slightly BEFORE the trunk can be opened.
2. Split the Python's trunk-pop output with two diodes. Connect one diode to the car's factory-alarm-disarm wire. Connect the other diode to a relay, configured for a positive output, to energize the motor that releases the trunk lid.
OTHER OPTION: Some remote starters (I'm not sure about the new DEI stuff) can be programmed to simply unlock the doors every time the trunk-release is pressed..........if your unit has this option, it would easily resolve your problem.........but you must also remember to re-lock the car when you're finished.
OTHER NOTE: You apparently haven't run into this yet, but I thought I'd mention it. Inside the glove box is a switch that disables the interior trunk-pop button, for valet parking.
If you move the switch, the aftermarket remote also will not open the trunk, as the output from the Python is simply connected to the same wire coming from the trunk-pop button.

Is there anything wrong with what I suggested....?

Thank You so much guys for the quick response, I guess it comes down to it can be done and basically he doesnt want to do it for the price. I just wish he did it properly when we discussed the install but whatever its a minor qualm I guess I'm going to have to live with. I'll try to get him to do it, but he might ask me for more loot which I dont know I guess its not worth it for something so minor. There was also another problem with the remote starter on this install where it would start but then 10 seconds later it would shut off and then restart again over and over again for about 3x and then just stop all together. This problem was intermittent and so he basically did some work around where now I do not get the audible beep that you would normally hear, after remote starting the car and pressing the brake pedal to disengage the alarm. Minor issues but I guess I got a good deal and this is what happens when you bargain shop. Quality isn't always good, with my other 2 cars I didnt have these problems but I did pay considerably more. I paid $430 installed for a Python 881xp with backup battery and glass sensor, which was a deal in my market.

factory alarm disarm with ch.2 (trunk pop) is defaulted to on in the programming menu of the python. all the installer had to do was hook up the factory alarm disarm wire (lt. GREEN/ black) to the door module and you shouldn't have any problems.
Factory Alarm Disarm WHITE/ blue - driver door module in door, pin 5
Notes: Meter this wire while turning the key in the driver door key cylinder.
Single pulse on this wire will disarm the factory alarm, and double pulse will unlock the doors.
On vehicles with left front only power window anti-pinch system, this wire is found at the BCM to the right of the fuse box, pin 7.

I wired up the factory disarm wire on my wife's 05 altima and have no problems whatsoever when popping the trunk. But I also know of another easy solution for cars (not just altimas) with this problem. You can wire in a relay in the trunk on the trunk pop wire directly before the solenoid. You can wire it up just like negative reversal doorlocks, but with just one relay.
