Sensor Functions Using J-46079

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