TPMS Sensor Identification Codes Each TPMS sensor has a unique identification code. Any time you replace one or more of the TPMS sensors or rotate the vehicle's tires, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched, to the tire/wheel positions, in the following order: driver's side front tire, passenger's side front tire, passenger's side rear tire, and driver's side rear tire using a TPMS diagnostic tool. See your GM dealer for service. The TPMS sensors may also be matched to each tire/wheel position by increasing or decreasing the tire's air pressure. When increasing the tire's pressure, do not exceed the maximum inflation pressure indicated on the tire's sidewall. You will have two minutes to match each tire and wheel position. If it takes longer than two minutes to match any tire and wheel position, the matching process stops and you will need to start over. The TPMS matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to RUN with the engine off. 3. Using the DIC, press the vehicle information button until the LEARN TIRE POSITIONS message displays. 4. Press the set/reset button to allow the system to learn the tire positions. The horn will sound twice to indicate the receiver is ready, and the TIRE LEARNING ACTIVE message will display. The TPMS system is ready for the sensor matching process to begin. 5. Start with the driver's side front tire. 6. Remove the valve cap from the tire's valve stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for five seconds, or until a horn chirp sounds. 366
