Normal Operation

WARNING: This page is about a different car, the 2010 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.

The Liftgate/Trunk Module (LTM) receives voltage from the Battery Junction Box (BJB) through circuit 1190 (YE/BK) and ground through circuit 57 (BK). When the button on the driver door trim panel, the Remote Keyless Entry (RKE) keypad or the RKE transmitter is pressed with the lid open, the Driver Door Module (DDM) sends a signal to the LTM, which grounds circuit 1600 (TN/RD) and sends voltage on circuit 1602 to the lid motor and lowers the lid until the latch closes. At this time, the module powers the closing motor on circuit 1603 (RD/LG) grounding circuit 1601 (WH/PK), slowly pulling the lid to a fully closed position. The striker down switch on circuit 1604 (VT/OG) and the striker up switch on circuit 1605 (VT/WH) within the closing motor are monitored by the module to determine when the closing motor is fully down or up.
