Normal Operation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The Parking Aid Module (PAM) receives a drive gear input from the PCM through the High Speed Controller Area Network (HS-CAN). A reference voltage and signal return is supplied to the active park assist sensors from the PAM  . The active park assist system may not display the "ACTIVE PARK SEARCHING" in the Instrument Cluster (IC) message center up to 7 seconds after the ignition is placed in the on position. This is part of the active park assist system initialization process.

The PAM  receives an input signal from each active park assist sensor to determine if the vehicle can fit into the available parking space. The PAM  sends and receives network messages over the HS-CAN  from the PCM, the Transmission Control Module (TCM) (hybrid), the ABS module, the Power Steering Control Module (PSCM) and the Instrument Cluster (IC). This intermodule communication is used to determine if the vehicle fits into the available parking space, to inform the operator and steer the vehicle (hands free) into the available parking space.
