The Nissan Path

Fiance has a 2007 Pathfinder and it's a nice suv. but it has some mechanical quirks.

I keep the engine very clean. No leaks, fluids always look good.
I am about to do a large preventive maintenance routine.
Replace:

Transmission fluid and Filter and bypass radiator to air cooler.
Flush and fill radiator.
Change serpentine belt
change pcv valve
oil and filter
air and cabin filters
Change rear brake rotors (just changed pads)
Drain and fill rear end fluid


Taking it on a 1000 mile round trip and want to make sure it's in top shape.
It has 79,000 miles.

Biggest issues that I am looking to solve;

Air Bag Light constantly flashing
Tire monitor light on when all tires at spec psi
noise comming from what I assume is the air dampner door in the dash. It click click clicks randomly when the a/c or ignition is off.
She told me she hears a rumbling noise sometimes, but it never makes it for me. As she said it comes from the back and the back pads were spent, I am hoping that is it. But as a caution I am draining my trans and diff fluids.


My DD is is a Tacoma. We both use the Pathfinder.
It is a 2007 with the 4.0 V-6 2wd Blue, third row, base trim.

I'd suggest getting the airbag sensor checked as it's likely it just needs to be reset. A properly run diagnostic will usually be able to determine what's setting it off and if there's actually an issue.

About your tire sensor light; with 79K miles, unless they've been replaced there's probably a sensor (TPMS) in one or more of the tires that has a low or dead battery. A decent tire shop will have a compatible scanner that they can check the sensors with and let you know if there's something wrong with them.

Hope that helps and welcome to the forum!
