Power Up/Down

WARNING: This page is about a different car, the 2012 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.

The Final Drive Control Module (FDCM) will power up with an OFF/ON transition of the hard wired ignition switch input.

The FDCM will power down when the vehicle ignition switch transitions from ON to OFF or there are no system requirements that dictate the controller to remain active
