Learn Mode Description: Notes

The tire pressure monitor (TPM) system uses the body control module (BCM), exterior lamp switch, 4 RF transmitting pressure sensors and the serial data circuit to perform the TPM learn mode functions. The sensor learn procedure must be performed after every tire rotation, BCM replacement or sensor replacement. Once the TPM learn mode has been enabled, each of the sensor unique identification (ID) codes can be learned in to the BCM memory. When a sensor ID has been learned, the BCM sounds a horn chirp. This verifies the sensor has transmitted it ID and the BCM has received and learned it. The BCM must learn the sensor IDs in the proper order to determine correct sensor location. The first learned ID is assigned to the left front, the second to right front, the third to right rear and the fourth to left rear.
