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 passive key the Tire Pressure Monitor (TPM) module receives the signal and communicates the remote start request message to the BCM. The BCM transmits the message via the Medium Speed Controller Area Network (MS-CAN) to the BCM to initiate a remote start event. For more information, Refer to: Tire Pressure Monitoring System (TPMS) .
