Howdy, I'm new to this forum, but have been a mechanic doing all my own work for more than 35 years. My NV2500 is three years old. I consider Nissan's TPMS and their dealers' handling of it an abomination. At Michael Jordan Nissan in Durham, NC (where we bought the van), they would charge an extra ~$40 to reset the TPMS when the tires were balanced an rotated. But they didn't do it. They also didn't adjust the tire pressures from front to rear; they'd just swap 'em and pay not attention. After that, obviously I wouldn't let these people clean up after my dogs. (These are the same people who tell you the oil and filter have to be changed at 3700 mile intervals. Blatant selling of unnecessary service.) Then I took the van to a nearby tire store where I've done other business with trucks. These guys put the rears on the fronts at 80 psi, then put the front on the rears and aired them up to 80 psi. I guess that's one way to keep the TPMS from reporting an error. I discovered this on a routine tire pressure check, because I have no use for the blasted TPMS and maintain my tires the old way. Which works and is reliable. But now the stupid thing keeps reporting errors -- that there is only 50 psi in the rear tires, which are of course now on the front. There's got to be a way to zap the TPMS and make it re-learn the tire locations. Believe it or not I have other things to do, but since no easy answer is available I'll look into and see if something can't be figured out. Will report here if I get anywhere with it. -Ranch Hand
