Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be be posting a replay ASAP

Expert:  Chad Farhat replied 1 year ago.

you need to have the car scanned with a Nissan scanner or equivalent and read the anti theft module for fault codes and identify what is failing , the security module , the key, the door switch the hood switch , the antenna etcc.. and then replace that part and clear codes again

the scanner at advance auto or auto zone only read engine module , so that want work

Get the codes retrieved and post to back here to me and let you know what is failing and how to replace , if you planing on doing this yourself

some components will require to be programed by a scanner

I sent you a link for the components that you can check your self

what are steps to check that alarm system is working or not...means how can i simulate the scenario in which alarm gets triggered....thats would be good test to check the system...
Expert:  Chad Farhat replied 1 year ago.

keep driver door window down ,lock all doors and trunk and hood lock the car from driver side outside lock cylinder and pull the key out

then reach thru the window and unlock and open the door , that should trigger it , if you really want to, i sent you picture of horns, unplug them ? it will stay go ff at night bu not siren noise :)

i still have few minutes , i just looked at the scanners needed , you taking $1100 cheapest that has Asian software needed

i know that is way more than the budget , might be cheaper to take to shop that has capable scanner and get what you need

all other scanners for most part code readers , maybe some live data , but that is about it, like European cars has specific Europeans software same thing with Asian cars

Customer: replied 1 year ago.
Sure...lets talk @7pm EST timing.Please see all the information which i provided you.thanks
Expert:  Jay replied 1 year ago.

Thanks for waiting for me. Lets see if we can figure this out for you. Of course it would be easier with a scanner to see what the alarm is seeing open that is causing the alarm to go off. So what I am going to ask you to check may require some time to isolate if possible.

First I want to make sure the alarm light you are looking at is the one on the top of the dash by the windshield

Customer: replied 1 year ago.
i was talking about same alarm light which is ohe top of the dash by the windshield.
Expert:  Jay replied 1 year ago.

If you lock the car with the key, does it turn solid for 10 to 20 seconds then flash?

Customer: replied 1 year ago.
Hi Jay,I just checked that light on dashboard is not flashing now...(car is parking under sunlight...it could be not visible to me )...
Expert:  Jay replied 1 year ago.

What state are you in?

Customer: replied 1 year ago.
San Jose in CA.
Expert:  Jay replied 1 year ago.

Ahh. I am in NJ so we have a big time difference. Well let me start with explaining how the factory alarm system works. Cause we want to see if it's working properly or not as a first thing.. Give a few mins to type out how it works.

Customer: replied 1 year ago.
ok Jay...but i checked yesterday night that LED was flashing on dashboard.
Expert:  Jay replied 1 year ago.

The Factory alarm system uses all door switches, truck switch and if equip, a hood switch. These switches all tell the Body Control Module (BCM) the vehicles state. If a door is open or closed and so on. So when you go to lock the car, the BCM wants to see all of those switches in a closed position. If it doesn't, it may not arm the alarm properly or can cause it to go off like you are explaining. Now it is normal for that light to flash most of the time. To know if the system is operating, meaning it's seeing all the closed signals when you lock the car is if the security light turns solid after you lock it and it stays solid for 10 to 20 seconds then blinks.

So that is one operation we need to check first. Once we have checked that, and if it does turn solid, then let me know.

Customer: replied 1 year ago.
Ok Jay..let me go and check it again.
Expert:  Jay replied 1 year ago.

ok

Customer: replied 1 year ago.
Jay..this time i am seeing that LED at dashboard is not flashing and it doesn't turn solid after locking the doors.
i opened all doors and trunk and closed properly....but nothing happened..but i know yesterday night it was blinking and its turned solid after locking the door.
Expert:  Jay replied 1 year ago.

Ok... cool. If you go around and open each of the 4 doors, does the dome light come on?

Customer: replied 1 year ago.
Hi Jay...this time when i went to check..that LED was flashing on dashboard.
I opened all door and checked that dome light didn't come up.
Expert:  Jay replied 1 year ago.

The dome light did not come on with any of the doors?

Customer: replied 1 year ago.
i think dome light (i think its a light above between the fornt seats..please confirm) is switched off thats why it didn't come up.
If you want i could go and turn on that light and lock the car then again unlock the door and open the door/doors.
Expert:  Jay replied 1 year ago.

Yes, make sure the setting on the dome light is for the doors so it comes on and off when the doors are open and closed

Customer: replied 1 year ago.
I checked that dome light is always "on" when it is in "ON" or "middle"..irrespective of door opening or closing.
when its "OF" then always "off "...irrespective of door opening or closing.
Expert:  Jay replied 1 year ago.

ok.. If it's always on when it's in the Middle, it means it is seeing something is open which can certainly affect the alarm issue you are having.

How handy are you?

Expert:  Jay replied 1 year ago.

https://dl.dropboxusercontent.com/u/105565483/IMG_38211.jpg

That is the position it should be in so when you open the door the light comes on.

Customer: replied 1 year ago.
i am talking about this pic.
Customer: replied 1 year ago.
ok..i got it..please advice what i need to do next.
Expert:  Jay replied 1 year ago.

That is the dome light. But you it should be in the middle like my image for it to come on and off when the doors are opened and closed.

How handy are you?

Customer: replied 1 year ago.
when i checked it was in the middle...might be when i clicked picture on that time its off.
Expert:  Jay replied 1 year ago.

You should only have been charged for this one question.

Customer: replied 1 year ago.
I already paid $20 for this question....please advice what i need to do ?..do you want i need to call customer care .
Customer: replied 1 year ago.
regarding dome light..i checked they are off when all doors are closed and LOCKED.......when unlock then its turned on...even doors are closed.
Expert:  Jay replied 1 year ago.

So the dome light is working properly? It may turn the dome light on when you unlock the car. The key thing is that each door you open the light turns on, and when you close the door, the light goes off.

Expert:  Jay replied 1 year ago.

Customer: replied 1 year ago.
about billing i will talking to customer care..thanksRegadring dome light...
It may turn the dome light on when you unlock the car.
>>Yes unlocking the car turn on the dome light.The key thing is that each door you open the light turns on, and when you close the door, the light goes off.
>>yes when i open the door (def. after unlocking) it turn ON....and it will be turn ON only after opening the doors also...but when close the door and lock (i was inside in the car when tested) then only dome light turn OFF.
Expert:  Jay replied 1 year ago.

Don't lock the car. Leave it unlocked.. then start the car and turn it off. Open the drivers door should turn the light on. Then close it. The light should go off with in 10 to 20 seconds. Then try the next door and see if each door turns the light on

Customer: replied 1 year ago.
i checked and found that when start the car and turn off...dome light turns ON.(even doors are unlocked)
I didn't found any situation where doors are closed or unlocked and dome light is OFF.
Expert:  Jay replied 1 year ago.

The dome light does have a timer. If you close the doors and wait. Does the dome light ever turn off?

Customer: replied 1 year ago.
Want to address 1 thing also....that alarm triggers daily almost 4:00AM...don't know why this time.
and alarm triggers just for 1-12 seconds only....after that stop..
Expert:  Jay replied 1 year ago.

Every morning? Does a train go by or anything?

Customer: replied 1 year ago.
No train nothing ..even changed my parking place as others were getting problem....same problem...might be some loose connection...not sure..few days ago there was no alarm as might be alarm system disabled (LED was not flashing that time and when i triggered to simulate attack..then also alarm didn't triggered )..but now LED is flashing and getting this issue almost daily in the morning.
Expert:  Jay replied 1 year ago.

This alarm is not a motion triggered alarm. It would only be set off if it sees a signal from a switch. Possibly from a door adjustment or a bad door switch. That is why I am trying to have you check the door switches.

Customer: replied 1 year ago.
hi jay...i just checked and found that car dome light turn off after closing all doors (it took around 10-12 seconds to turn OFF)..then i opened and closed all door one by one ....dome light turns ON after opening the doors and turn OFF closing the doors..checked with all 4 doors.
Expert:  Jay replied 1 year ago.

Perfect.. That is good.

Now lets open the hood and see if you have a hood switch. Once you open the hood, do you think you can take a picture of your whole engine bay area so I can see if I can locate the switch?

Expert:  Jay replied 1 year ago.

It is normally located by the drivers head light and front grill area

do i need any screwdriver or wrench to unplug it...
Expert:  Jay replied 1 year ago.

You can simply either reach in and unplug it. If you can't reach the plug, the switch is secured by one 10 mm bolt. So if you take that bolt out, you can remove the switch and unplug it that way also.

Customer: replied 1 year ago.
Is there any problem I could face after detaching this hood switch... please confirm
Expert:  Jay replied 1 year ago.

All you are doing by unplugging this is eliminating that part of the security system.

Meaning, the Alarm wants to see all doors, trunk and hood closed for it to arm. If you unplug the hood switch, it will not look for it. It will only look for the doors and trunk. So all you are doing is eliminating that part of the security system by unplugging it.

Customer: replied 1 year ago.
let me update you after 2-4 days if alarm doesn't trigger....if it triggers then ping you immediately.
Expert:  Jay replied 1 year ago.

The alarm should not be disabled. But if it stopped going off you can leave it like this!

Customer: replied 1 year ago.
why i am telling disable...because i didn't see LED light flashing at dashboard.
Expert:  Jay replied 1 year ago.

The factory alarm can not be disabled. When the alarm is going off, do you see the parking lights flashing or the head lights flashing?

Customer: replied 1 year ago.
I will watch for flashing the lights once again...as I remember I saw last time parking lights were not flashing...
Expert:  Jay replied 1 year ago.

The lights flashing would tell me what type of alarm the car has.

The factory alarm light with the hood switch unplugged should still turn solid when the car is locked for 10 to 20 seconds, then start to flash.

Customer: replied 1 year ago.
Is there any method to reset the programming of alarm system (might be take out the battery wires and connect it back after 5-10 mins....)....not sure this will work or not....just let me know your advice...I want to address 1 more thing that around 2-3 months back i changed spark plugs and laminated few cables which are close by to that engine compartment with isolation tape....
Expert:  Jay replied 1 year ago.

I am limited to one topic per question.

The factory alarm does not have any type of reset.

Customer: replied 1 year ago.
Ok Jay.The factory alarm light with the hood switch unplugged should still turn solid when the car is locked for 10 to 20 seconds, then start to flash.
>> I am not seeing any LED flashing/turn solid at dashboard for a long time after taking out hood switch (also saw that LED behavior intermittently turn ON/flashing and turn off after giving attention on this issue)....(presently LED is always turn off).

It stopped flashing after unplugging the hood switch? Has the alarm stopped going off?

It stopped flashing after unplugging the hood switch?
>>Yes..Please advice about it.Has the alarm stopped going off?
>>Yes.....Did not hear and not reported by any neighbor.
Expert:  Jay replied 1 year ago.

Well if the alarm stopped going off after the hood switch has been unplugged, that means we have isolated the cause of why the alarm was going off. So lets just plug it back in now and then see if the alarm light returns to normal operation.

Let me know
