Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
TPM Learn Mode Description
The Tire Pressure Monitor (TPM) system uses the remote control door lock receiver (RCDLR), body control module (BCM), driver information center (DIC), 4 radio frequency transmitting pressure sensors, and the serial data circuit to perform the TPM learn mode functions. The sensor learn procedure must be performed after a tire pressure sensor, or RCDLR replacement. Once the learn mode has been enabled, each of the sensors unique identification (Id) codes can be learned into the RCDLR's memory. After the RCDLR has received a sensor transmission, it sends a serial data message to the BCM to sound a horn chirp. This verifies the sensor has transmitted its Id and the RCDLR has received and learned it. The RCDLR must learn each sensor's Id in the proper order to determine sensor location. The first learned Id is assigned to the left front location, the second to right front, the third to right rear, and forth to left rear.
