I have a Viper alarm in my 95 Maxima that was put in by a very reputable company. But more often than not, when I disarm the alarm, all the doors, except the driver's, lock up again. Also happens when I close the driver's door (with alarm off) Anyone have a clue what's going on? Viper and Nissan have no clue... HEEELLLLLPPPPP!!!

 

I just bought the 600 ESP for my 98. You may have a problem with your lock in the first place. You also may have a problem with "multi-level" arming, where you can bypass certain zones, depending on your model.

 

Here is a little exerpt from http://web2.airmail.net/scutchen/max_faq/
that may help you out.

Q: I had an aftermarket alarm installed in my 95+ Maxima. However it doesn't always unlock the doors when disarming, and when it does unlock the doors, there's a delay.

A: Courtesy of Matt:

I solved this *exact* same problem on my '97 SE. I had a Clifford SuperNova II installed because I do not have the factory alarm. The installer tells me that Nissan's have this one-pulse/lock, two-pulse/unlock thing with the keyless entry and the aftermarket alarm has to duplicate the timing of the two-pulse correctly or the doors won't unlock. Anyway, he installs a relay in the door that is triggered by the Clifford to make the two pulses. Everything seemed to work fine at first, but I noticed that when it got cold out, the doors wouldn't unlock with the remote (they'd always work with the inside door switch). He tried playing with the timing on the relay and the value of the capacitor driving the relay but it didn't work.

So I took it to another installer and this kid knows his stuff. He says the way to avoid this problem is to solder the aftermarket alarm output lead direct to the PC board of the door lock switch. He explained that since the door switch always unlocks the locks, *it* knows how to correctly send the two-pulse signal. The way mine (and probably yours) was set up was the alarm would send a signal to the relay, which was driven by a capacitor, that would duplicate the two-pulse signal and send it to the door lock *circuit*. His way has the alarm signal going directly to the door lock *mechanism* which already knows how to send the correct two-pulse signal. He told me he called Clifford and they had never heard of the particular door lock PC board that is in the '97 driver's door, so he called Nissan and--get this--supposedly *Nissan* had never heard of this PC board for the driver's door lock.

Anyway, this kid soldered the alarm output directly to the circuit board and now my locks work perfectly all the time. If yours is hooked up like mine was, when you disarm the alarm, the alarm will chirp (to indicate it is disarmed), and then you hear a bunch of clicks (if you're close enough--the relay is doing its thing), and then the door locks pop--about a 1-2 second delay after the alarm is disarmed. With the output directly soldered, there is *no* delay, and the locks pop instantaneously with the alarm arming or disarming. It's perfect.

Now I'm pretty good with doing my own electrical wiring on my car, but I have no idea what he actually soldered to what. Your best bet is to call him direct. He works at Tweeter in Newington, CT and his name is Chris (ask for Chris in Mobile/Installation). Their phone number is (860)-665-0606. I'm not plugging Tweeter or their services. In fact, the first tech that installed my Clifford also worked for Tweeter and although he did a meticulous install, he obviously didn't know the correct way to set this up. I don't know if this will work for all '95+ Maximas or not, but it definitely works for a '97.

It's not the same symptoms but I think it may be the same problem.
