Component Description: RTM
WARNING: This page is about a different car, the 2023 Lincoln Nautilus. However, it is still accessible from the selected car via links, so may be relevant.
The RTM communicates all RKE and passive key information to the BCM over a LIN-based circuit whether or not the CAN is active. The RTM is a receiving antenna that receives the high frequency signals from passive keys.
The RTM requires PMI when replaced.
