Learn Mode Description: Notes

WARNING: This page is about a different car, the 2005 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

The Tire Pressure Monitor (TPM) System uses the antenna module, dash integration module (DIM), keyless entry transmitter, 4 radio frequency transmitting pressure sensors, and the serial data circuit to perform the sensor learn functions. The sensor learn procedure must be performed any time a sensor is replaced, or after the vehicles tires have been rotated. Once the learn mode has been enabled, each of the sensor's unique identification codes can be learned into the antenna module's memory. When a sensor's identification (ID) code has been learned, the antenna module sends a serial data message to the DIM to sound a horn chirp. This verifies the sensor has transmitted it's ID code and the antenna module has received it. As soon as the first sensor ID code is learned, all other IDs are erased from the antenna modules memory. When the last sensor's ID has been learned, the DIM sounds 2 horn chirps.
