Power Up/Down

WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

The DTCM will power up with an OFF/ON transition of the hard wired ignition switch input.

The DTCM 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
