I do understand what's being stated. I just don't understand how you know it's an hour before it updates.
If I add air pressure it shows up immediately, not an hour later. If I take my sensor off the tire it beeps immediately in the cab, on the monitor. I have taken a sensor off and down to the garage, out of range, and the monitor is beeping when I came back up to the truck, about 10 minutes later. All of this would seem to negate the claim that it takes an hour to realize a sensor is missing, or that a reading is out of standard.
