Congratulations bigendbob!!
Today I finally completed my service reset issue for the rear brake pads.
I had attempted to perform Service Reset without replacing the pad sensor cable. Yesterday I bought new one from my dealer and made a big smile to see the mileage reset to 28000 miles. It was an education for me that the sensor is a two wire /two stage design. I had worn through the first and second level and ignorantly tried to reuse the sensor as we use to do decades ago. Here's a few helpful pics for familarity with sensor wire/connection.
