The system must have been reset when the inflation pressure was correct; otherwise, reliable signaling of a flat tire is not ensured. Always use wheels with TPM electronics to ensure that the system will operate properly. Reset the system after each correction of the tire inflation pressure and after every tire or wheel change.
