Sensor Functions using J-46079

Each sensor has an internal low frequency (LF) coil. When J-46079 is used in activate mode it produces an LF transmission that activates the sensor. The sensor responds to an LF activation by transmitting in learn mode. When the PDM receives a learn mode transmission while in TPM learn mode, it will assign that sensor's Id to the location on the vehicle relative to the order in which it was learned.
