Passenger Door Lock

[zypor]

Need feedback : 2011 Pathfinder Passenger door lock switch. Door Lock Switch operates normally with ignition on. Will operate the door lock for 2 cycles, of the lock, or about 15 sec after ignition turned to off. After that 15 sec. door lock switch will not operate i.e. lock door. My wife remembers using the switch to lock the doors after getting out of car but does not remember if that is within the 15 sec time frame after ignition turned off. Can anyone confirm that the passenger door lock switch will operate locks after waiting 15 sec after the ignition switch turned off?

That stuff is all firmware-controlled in the BCM and the two window switches, which are all connected by a local bit-bang network (LIN). I know the lock switches should continue working for as long as the doors remain closed and the BCM hasn't gone into "battery saver" (I think about 20 minutes). After that, or once a door is opened, the BCM will cut retained power and may down the lock responses along with it. I can't find any clear explanation about that in the FSM. If there is in fact a problem with the LIN getting locked up, it's usually a switch which has gone bad and not a BCM issue.

Thanks for the reply. I first noticed this problem after I replaced the Master door/window switch in the driver door about 2 months ago. Yesterday we had our first hot sunny day here where I live so I went to roll down the windows using the key fob and the windows would not go down. I've done this many time before. Doing some additional troubleshooting I discovered that the key in the door lock was not working as it should. I use to be able to roll down both front windows using the key in door lock by going to unlock position twice and holding it there. Now when I do this the Passenger window will go down but not the Driver window. Just a note all of the switches in the master switch work properly and all individual window/door lock switch work except as noted in my first post.

That almost certainly means it's the wrong switch with the wrong software. Did you buy it using the Nissan part number, or by make-model-year? If the latter, that was a mistake. Nissan has a gazillion lookalike window switches that aren't the same on the inside.

The switch is no longer sold by Nissan I even tried sources in Japan. Only option was to by one on eBay. I did use the Nissan Part number when searching. Been doing reading on the web about resetting the BCM. When I was working on the car the battery went DEAD! All my windows where up HOOD was shut and the doors where locked. To my suprise the key will not unlock the door when the battery is dead. To gain access I put a trickle charger on the starter cables under the car for about 1/2 hour to get enough juice so I could unlock the car and open the hood. IF the battery goes DEAD could the BCM require resetting? Is it possible to reset on the Pathfinder?

There's nothing in the BCM to reset, although when the voltage goes into the "never never land" below about 8V it never hurts to do a hard reset after you recharge. You do a hard reset by taking both terminals off the battery and touching them together (or using a wire jumper if they won't reach) for about 5 minutes.

The lock not working on the door means something mechanical is screwed up, because that can't be an electrical issue. The cylinder is directly connected to the lock mechanism by a linkage rod, so if it didn't unlock the door, either the linkage rod or the lock has an issue.

That's weird about the part, because the book only shows two master switches used on an '11, 25401-ZL10A and -ZL10B. They're both superseded by -ZL10C (i.e., -ZL10C can replace either one). None of them show unavailable. Did you maybe get a wrong p/n somehow?

I'll try the hard reset. I may have gotten a wrong part number. I properly saw the ZL10A or ZL10B and it did not cross over to the replacement number. If the hard reset does not work I'll Look for a new switch.
Well I just did another check on the switch and it does x-over to the new number ZL10B to ZL10C. Not sure what happen. If reset does not work then I'll order another switch.

According to the Nissan dbase there are no other Nissan part numbers which cross, those are the only three spec'd for an '11 Pathy. If you're looking at an aftermarket xref, it's entirely possible it's inaccurate. If they're claiming a different Nissan equivalence, that's definitely inaccurate. I just did a quick search on eBay and there are lots of knockoffs, plus some gray market OEM for as little as $75. There are also several listings inaccurately claiming equivalence to a ZP80A, which actually fits '05~'08 and isn't likely to work in your ride. That kind of stuff can't be trusted, get the right number.

I tried the hard reset and it did not work. I'll order a new switch and see what happens. Took the door panel off found no problem with the door handle to door lock rod. Rod appeared to operate as it should. While I was doing the hard reset (Battery disconnected) I tried unlocking the door with the key and it worked as it should. Don't know why it did not work before.

The OEM switch from Nissan fixed the problem Initial switch was aftermarket switch purchased from eBay or Amazon. Windows now go down with the key fob the passenger door switch lock now works properly. Still have some problems with the driver door manual door lock. When it turns I can roll windows up-down and lock-unlock door. But there are time when I can not turn the key in the lock. It just won't turn. I found this video online about a Nissan hood latch. Owner replaced latch with an aftermarket latch and it caused all sorts of problems just for info on replacement parts especially electrical ones.

That can only be a mechanical issue. Try some graphite in the cylinder, if that doesn't help then pop the door panel and disconnect the linkage arm to determine whether the glitch is in the cylinder or the lock assembly. If it's in the cylinder, try getting a new blade cut using the factory key code before you assume the cylinder is faulty. Keys wear out more often than cylinders.
