Why the Correct TPMS Frequency Does Not Always Guarantee Communication
Frequency is a necessary RF check, but reliable TPMS communication also depends on modulation, protocol, data framing, activation and vehicle reception.
Frequency is only one condition
A 315MHz or 433MHz match does not prove that the transmitted message uses the format expected by the target vehicle.
What must be checked
The review should cover ASK or FSK modulation, bit rate, Manchester, PWM or NRZ encoding, identifier handling, checksum or CRC, packet timing and activation method.
