Tx5 ... much thanks. I had started to test the sensors when I discovered my probes didn't fit inside the connector, but since the wheels were off I just swapped the sensors. Since my test procedure seems viable I will go back to that if I can get it to fail at a convenient time. And I'll research the module to see how to do a single test. Much thanks. I'll post results.
