'93 Pathfinder - How to disable security system?

Question

Hello all,My sister has a '93 Pathfinder, and her security system has some kindof bug in it that will cause the alarm to go off at random times.Any ideas on how to disable it (or fix it)? She bought the car new andthe system was already installed , so it's either factory or a dealerinstalled item.Her mechanic spent quite a while trying to figure it out with no luck.BTW, the owner's manual is no help.Thanks for any tips or advice,PaulP.S. The car also has a short in the elec. door locks (been that wayfor many years), but I don't suppose there's a relationship here, isthere?

If I remember correctly, there is a switch on the console just under the arm rest. You can set the "vibration" setting, or somesuch. On my '94, the thing was so sensitive that a medium-loud motorcycle could easily set it off. I left that feature turned off for years.

yes its a factory installed system, mines a 94 pathfinder, exactly the sameas yours. underneath the driver seat is a small black box which is the alarmsystem, if its going off easily due to the "vibration/impact" detection thencheck the rear side if the box where a very small 3 position switch islocated, flip the switch all the way to the left, which is the leastsensitive setting, if you want to totally disable the "vibration/impact"part of your alarm then just disconnect the 2-wire pig tail connector atcomming out of the box, to totally disable the alarm alltogether, disconnectany and all wires coming from the alarm box. hopew this helps.

Funny I ran across this... I just disabled the security system on my '93 Pathfinder this afternoon for the exact same reason. I baught it used (w/ no remote) and the system would go off randomly (usually at 3am when it was raining... *ughhh*).

Here's the deal: - remove the 4 bolts that hold the drivers seat in place and pull it out. - under the carpet there is a box (mine has a "genuine nissan part" sticker or something on top.) *not to be confused with the box that is on TOP of the carpet. - unplug the main harness from the box (single row of pins). There is also a plug that has only 2 wires in it ( in a |-- orientation). This is to disable ignition. If the two wires are jumpered, the car will start -- if open, it won't.

VOILA! I've been driving around all day and messing with it and no alarm! WOO HOO!

Oh yeah, put your seat back in... :-)

Now can anyone tell me what the other box under the driver's seat is? Small audio amp? Email me if anyone knows. Thx.

Good luck,

BTW, I bought two Nissan remotes on ebay for $19 each.  Came with easy instructions, and I quickly programmed them for my girlfriend's I30t. Maybe she'll not leave the fob on the roof anymore.

Thanks for your post. My sister swears that there's no box under thedriver's seat, but I'll have to look for myself after your post.chisel

Like I said, it is UNDER the carpet... you really can't find it too well without pulling the 4 bolts and lifting the seat. If you DO try to find it without lifting the seat, you have to do it by reaching under from the FRONT of the seat, because that is the direction the carpet lays on top of it.

Good luck,
