The P0705 is that Range Switch again, it's probably a leftover from when you replaced it. The U1000 is a no-comm code and probably means a dead brain, and the PABI (actually the whole OCS system) won't operate with a dead brain. So if it's been that way for awhile, I'd take a peek under the console and see if someone drowned it in soda pop, or maybe you bought a repaired flood car and didn't know it. If it is dead, none of your airbags will be functional.
Replacing it is simple but finding a good used part won't be, at least if you want it to be plug-and-play. Nissan uses the same generic brains on dozens of models and just changes the firmware, so you can't go by the part number label on the unit. That means the only way to assure an identical used part is to get one off an applicable vehicle. NissanPartsDeal shows your p/n as 98820-5Z080. It goes for $496 list, $333 from NPD, and it only fits '04~'06 Quest. The good news is, it appears to fit all '04~'06 Quests regardless of trim, so it might be hard to find from a JY but not impossible. Get it from a reputable JY if you go that route, because it has to come from a vehicle that was scrapped for mechanical reasons and not because of collision. You can send a collided unit out to be reprogrammed, but those places generally only clear the flash memory and don't check the squib drivers, so I don't trust the method. It's rare, but you can end up with a unit that seems okay can't blow one or more of the airbags in a crash.
