I installed your Zus TPMS system last week and I am having a couple of issues.
The first issue is that they are reading low on all 4 tires, though they are reading consistently low at about 18 psi on the front tires and 20 psi on the rear tires. I am running 70 psi front and 75 psi rear on an F250 pickup truck. I have checked the actual pressure with multiple tire pressure gauges. As per your message board I have tried replacing the batteries, which I did last Friday and I am still getting the same low readigs…
My second issue is the system will not reliably communicate with my phone, a Samsung Galaxy S8Plus if the phone is too close tothe TPMS unit
it will not connect, and must be held at least 4 or 5 feet away which often means standing outside the vehicle in order to get a reliable connection.
