Normal Operation

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

During each vehicle start sequence, the powertrain control module (PCM) queries the encoded key and compares the information with the key information stored in the PCM memory. The PCM then enables the starting functions of the engine. The transceiver provides the interface between the encoded ignition key and the PCM.
