Power Up/Down

The Drive Train Control Module (DTCM) will power up with an OFF/ON transition of the hardwired ignition switch input, or with the presence of active Controller Area Network (CAN) C (CAN-C) communications.

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