 If a TPM sensor or its position on the car are changed without re-registering the IDs, then the TPMS warning light will turn on and stay on until the IDs are re-registered..If there are multiple antennas or receivers, this permits localisation of the TPM such that the vehicle can tell from which wheel the pressure data has come.As an alternative to this method, the vehicle can be programmed at the time of manufacture with the position of the tire together with its TPM serial number.
