Perplexed by TPMS
According to the manual, the TPMS light only tells you when there is a problem with the TPMS system. The low pressure light is separate and will come on with low tire pressure. Here's the thing. My bike is a 2015 with just over 1,000 miles on it. When I went to look at the bike before I bought it two weeks ago, the TPMS light was on. The owner put some air in the tires and the light went out. At that time I hadn't seen the Owner's Manual yet so I didn't think anything of it and had no reason to thing the system might be malfunctioning.
About 4 days after I bought it, the light came on again. Again, not having read the manual yet, I checked the tire pressure and it was about 1 psi low in the front, 4 psi low in back. So, I put air in and the sensor light went out. Last week, same thing happened, but this time I propped the bike up on the center stand and found a nail in the rear tire. That led me to believe the whole thing was due to a slow leak, so I replaced the tire and thought life was good.
I finally got around to reading the manual this week and found out the TPMS light doesn't indicate low pressure. Sure enough, it came back on yesterday, new tire and all. This time I didn't bother checking the pressure. I got of the bike, left it running for a few minutes while I puttered around in the garage and it went out.
Any thoughts on why this could be happening? I wouldn't think the TPMS unit itself is bad. It's brand new.
