These are tire pressure monitors and nobody can read them. Shouldn't be a problem, but it is. These counters can read data from most sensors, but not them. They won't work. I bought 5 about a year ago and they never worked and I expect they never will. Can not be read. Spent some money on sensors and installed them. Called Mobiletron even though they don't know about it. I have to work on getting a refund and paying again and again. Very bad business model from Mobiletron and they will never call you back as they say. Use VDO sensors, not Mobiletron. VDO will always work, at least until the batteries run out. from 6 to 8 years. The rating is extremely bad.
