  "textContent": "A method to facilitate secure communication between a first tire pressure monitoring system (TPMS) and a vehicle is disclosed. The method may include obtaining a trigger signal to auto-locate the first TPMS from a plurality of TPMSs. The method may further include obtaining learning mode advertisements from each TPMS responsive to obtaining the trigger signal. The learning mode advertisements may include a random value and a test value associated with each TPMS. The test value may be an encrypted value generated using TPMS keys. The method may further include calculating a vehicle test value using the random value and a vehicle pre-shared key, and comparing the test value with the vehicle test value. The method may further include auto-locating the first TPMS based on the comparison. The method may include receiving vehicle tire condition data from the first TPMS responsive to auto-locating the first TPMS.",
