TPMS Matching Process for Vehicles with Remote Keyless Entry (RKE) 1. Set the parking brake. 2. Turn the ignition switch to ON/RUN with the engine off. 3. Press and hold the Remote Keyless Entry (RKE) transmitter's lock and unlock buttons, at the same time, for about five seconds to start the TPMS learn mode. The horn sounds twice indicating the TPMS receiver is ready and in learn mode. 4. Start with the driver side front tire. The driver side front turn signal also comes on to indicate that corner's sensor is ready to be learned. 5. Remove the valve cap from the tire's valve stem. Activate the TPMS sensor by increasing or decreasing the tire's air pressure for about eight seconds. The horn chirp, can take up to 30 seconds to sound. It chirps one time and then all the turn signals flash one time to confirm the sensor identification code has been matched to the tire/wheel position. 6. The passenger side front turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the passenger side front tire and repeat the procedure in Step 5. 7. The passenger side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the passenger side rear tire and repeat the procedure in Step 5. 8. The driver side rear turn signal comes on to indicate that corner sensor is ready to be learned. Proceed to the driver side rear tire, and repeat the procedure in Step 5. 9. After hearing the single horn chirp for the driver side rear tire, two additional horn chirps sound to indicate the tire learning process is done. Turn the ignition switch to LOCK/OFF. If no tires are learned after entering the TPMS learn mode, or if communication with the receiver stops, or if the time limit has expired, turn the ignition switch to LOCK/OFF and start over beginning with Step 2. 10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label. 11. Put the valve caps back on the valve stems. 5-68
