WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The Tire Pressure Monitor (TPM) module has a dedicated single circuit network to the RFA module and is a receiving antenna that receives the high frequency signals from an IA key and RKE commands. The TPM module also receives Tire Pressure Monitoring System (TPMS) data. The TPM S data is sent to the Body Control Module (BCM) on the Medium Speed Controller Area Network (MS-CAN).
