Patent ID: 7358852

Claim:
A vehicle tire pressure monitoring (TPM) system, the system comprising: an immobilizer transmitter that transmits at least one low frequency (LF) sensor diagnostic signal; at least one TPM sensor having a memory, wherein the at least one TPM sensor comprises a transceiver that receives the at least one LF sensor diagnostic signal and, when the at least one TPM sensor is operating properly, presents at least one radio frequency (RF) message signal; and a TPM receiver that receives the at least one RF message signal and provides an indication to an operator when the at least one RF message signal is received, wherein the LF sensor diagnostic signal is adapted for transmission to determine proper operation of the at least one TPM sensor and re-configure the operating parameters of the at least one TPM sensor and the LF sensor diagnostic signal is adapted for transmission in connection with a TPM sensor association to include a TPM sensor identification that is selected from a bank of sensor identifications stored in the immobilizer.
