Differential Electronic Module (DEM): Removal

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.

NOTE: If installing new components, there is no reason to remove the seals from the old components.

NOTE: The differential electronic module (DEM) and solenoid valve are calibrated together and must be installed as a set. If installing a new DEM or solenoid valve, install them as a set only.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING .
Disconnect the DEM by pushing the connector tab through the slot while pulling the connector out.
