So I had a pretty bad day yesterday...started when I broke 4 ribs in a bike crash last week, but that's for another forum...
So on the way to work I got a flat. Changed to spare. Front tire (this turned out to be important). Spare looked fine but afterward I checked the pressure and it was 34 vs sidewall number of 60 (also important).
Made it to work. Left work in warmer afternoon and drove about 60 for 5 miles and got "AWD HIGH TEMP. STOP VEHICLE". I stopped. Looked under car and saw stream of fluid. Got back in and called Nissan Service for a tow. Turned out it was air conditioner condensate and I was jumped to conclusion it was ATF. Sore ribs kept me from better checking this out.
Tow truck took 4 hours (ridiculous, but this isn't a rant). In the hours that I was waiting I googled the alarm and found people get it when AWD comes on at highway speeds because spare is smaller, especially if pressure is low. The AWD interprets the different size tires as slippage and comes on when it shouldn't.
So here is my question: Is there a fuse I can pull or a wire I can put a switch in to disable the AWD when using the spare? This is a design issue but I don't expect Nissan to fix it so I'm looking to fix it myself. I'm sure there are members who are familiar with the electrcal system that can help me here.
I also considered getting a full size spare. But I don't think the Bose subwoofer would fit in a normal wheel. It is custom designed to fit in this wheel. Also, I've read that even with uneven tread wear this can be a problem so even with a full size spare, if tread depth is different on the R and L, AWD will come on.
So I'm willing to listen to suggestions but a way to turn AWD off would be best in my mind.
