Disconnecting Mode
WARNING: This page is about a different car, the 2019 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
To allow disengagement of the RDU, no torque is routed through the power transfer unit, with the dog clutch being disconnected during this mode. Depending on vehicle operating conditions, the AWD module may keep the power transfer unit engaged for the remainder of the key cycle. The AWD module will send a duty cycle command to the power transfer unit actuator motor to disengage the dog clutch.
