Code C0381 2014 GMC Sierra Description

The Transfer Case Motor, also known as the transfer case range actuator, is a bi-directional, permanent magnet, DC motor. When energized, through the transfer case clockwise circuit or transfer case counterclockwise circuit, the ground is provided by the opposing motor control circuit which becomes grounded through the transfer case control module ground circuit. The transfer case range actuator, through a series of gears, rotates the transfer case control actuator shaft which moves the transfer case two/four-wheel drive actuator cam and transfer case high/low shift fork in order to shift the transfer case between the following modes or ranges: 2WD, 4WD/AWD Automatic, 4WD High/Locked, 4WD Low and Neutral.
