Power and Ground Requirements
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The power requirements for the PSD are two battery supply circuits to each PSD. The SJB fuse 11 (5A) supplies battery logic power required for the software and internal switching operations for both the PSDs. The LPSD motor, clutch and latch release actuator power is supplied by BEC fuse 16 (30A). The RPSD motor, clutch and latch release actuator power is supplied by BEC fuse 5 (30A).
Ground for the PSD is a separate single connection for each module. Some of the continuous inputs which are at a ground state when ON are also used for logic switching.
The ignition switch source is from the SJB fuse 13 (5A) for both PSDs. The ignition power is used for diagnostic functions.
