Okay, so, this is my first 4WD vehicle. I just got it 6 weeks ago. It is an 06 Pathfinder LE. I usually set it to AUTO, and that's generally how it's driven being I live in the mountains and it never flipping stops raining.
Sunday 4/19, steep incline downhill hunting the Pokemon, I see the warning light is on and the dash symbol indicating what mode I am driving in is blank. I have no idea what that is, but assume it's not bad because I'm living on a prayer.
Monday 4/20, having to wait in the car with all 4 kids at the urgent care because my daughter is sick. COVID has us sitting in the vehicle I have the car off, set to accessory mode so it's playing the radio still. Battery ends up dying, my own fault. Good thing, though, because apparently my battery was bad and a bit small. Get it jumped.
Tuesday 4/21-Thursday 4/23, continue driving in AUTO. Off and on the 4WD warning light comes on. Either when on completely flat, dry asphalt or when trucking uphill, does not seem to matter.
Thursday I set to 2WD thinking hey, that might fix it.
Friday I replace the battery. Much better fit, and immediately notice a difference in how it drives. BUT
the 4WD warning light keeps coming on. I followed some diagnostic advice from the forum (this one or another one, I don't know) as well as my mechanic (who didn't even come out, just told me to try a bunch of stuff). This ranges from switching while in Idle between 2WD and 4H, and it includes switching between gears, in different settings. I finally took it to not one, not two, but three auto shops, one who finally diagnosed it with the P1828 code.
I'm taking it to yet another place tomorrow because the place that was able to diagnose it was not able to service it, but I have absolutely no idea what is going on as it doesn't seem to be driving at all differently and I can find very limited information specific to that code and Nissan.
Am Trying so hard not to stroke out over Bernadette. I read somewhere to tighten and clean connectors and relay contacts but I have 1) no idea where these are located and 2) no idea if I even have the tools to do that. Any advice is appreciated, as my husband is typically not very handy so I have to do it by myself lol
