Tire Pressure Monitor (TPM) Module

The Tire Pressure Monitor (TPM) module is a receiving antenna that receives high frequency signals. When a remote start request is initiated from the Intelligent Access (IA) key the Tire Pressure Monitor (TPM) module receives the signal and communicates the remote start request message to the Remote Function Actuator (RFA) module. The Remote Function Actuator (RFA) module transmits the message via the Medium Speed Controller Area Network (MS-CAN) to the Body Control Module (BCM) to initiate a remote start event.
