TPMS Monitors

I think the comment about one tire being at a higher pressure just means the module will be reading 3 low pressure ones..or at least one of the lower ones should trigger it.

I was under the impression that the module compared the highest to the lowest and triggered the light when the difference exceeded a preset thresh-hold of difference, not a fixed number.
As an example say you loaded the back of your CUV up with several hundred pounds of camping gear, and it's a long trip, so you might be thinking 44psi, the max on the tire sidewall, might be a proper pressure. But you leave the front at 32, the same pressure you have always run, cuz the that's what it takes to keep the treads wearing properly. But now you have a disparity of 12 psi. This should trigger the warning.
But if I was the programmer, I would tell the module to ignore this after say three key on/off cycles, and to resume looking for a one-tire pressure loss. I mean, that would be logical right?
But honestly I have no clue how these devices are programmed. I just wish my wife would inform me of when an unfamiliar light shows up.
