2 Way Advanced Remote Start Antenna
WARNING: This page is about a different car, the 2010 Saturn Outlook, 2010 GMC Acadia, 2010 Chevrolet Traverse, and 2010 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
The 2 Way Advanced Remote Start antenna sends and receives radio frequency (RF) communications between the keyless entry transmitters and the remote control door lock receiver (RCDLR). The keyless entry antenna also receives RF signals from the tire pressure monitoring (TPM) sensors located at each wheel and sends this information to the RCDLR.
A coax antenna lead connects the antenna to the RCDLR. When a transmitter button is pressed, the RF signal sent by the transmitter is received by the antenna and the communications are inputted to the RCDLR. The RCDLR also sends information to the transmitters via the antenna.
