TPM Module
WARNING: This page is about a different car, the 2016 Ford Special Service Police Sedan and 2016 Ford Police Interceptor Sedan. However, it is still accessible from the selected car via links, so may be relevant.
The TPM module is a receiving antenna that receives high frequency signals. When a remote start request is initiated from the IKT the TPM module receives the signal and communicates that remote start request message via the MS-CAN to the BCM to initiate a remote start event.
