Sensor Functions
WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
Each sensor has am internal magnetic reed switch. When the J 41760 sensor activating tool is held close to the sensor, the reed switch closes, activating the sensor. See Special Tools and Equipment . The sensor responds to a magnetic 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.
