Normal Operation
WARNING: This page is about a different car, the 2010 Lincoln MKX and 2010 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The power liftgate on/off status is sent from the Liftgate/Trunk Module (LTM) to the Instrument Cluster (IC) over the Medium Speed Controller Area Network (MS-CAN) communication bus lines. When the RESET button is pressed, the IC sends a query to the LTM , requesting a system status. The LTM responds to the IC with the status of the system, either on or off. If the return status message is missing or corrupted, the IC does not display the brackets around either the ON or OFF selection.
This pinpoint test is intended to diagnose the following:
- Power liftgate system concern
- Communication network
