Sensor Function Using J-46079
WARNING: This page is about a different car, the 2007 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
Each sensor has an internal low frequency (LF) coil. When the J-46079 used in activate mode it produces an LF transmission that activates the sensor. See Special Tools . The sensor responds to an LF activation by transmitting in learn mode. When the RCDLR 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.
