Component Description: RTM
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The RTM communicates all RKE and PATS passive key information to the BCM over a LIN circuit and when the network is awake, the CAN. The RTM is a receiving antenna that receives the high frequency signals from Integrated Keyhead Transmitters (IKTs) and passive keys.
The RTM requires PMI when replaced.
