Code C0364 Cadillac Description

The front axle control circuit consists of an electric motor actuator that engages and disengages the front axle. The front axle engagement actuator consists of a permanent magnetic motor, a worm gear-controlled plunger, a front axle switch, and an electronic control circuit within the actuator assembly.
The front axle engagement actuator contains the following circuits: A Run/Crank Ignition 1 Voltage circuit, a Four-Wheel Drive Wheel Lock Indicator circuit, a Front Axle Actuator Control circuit, and a ground circuit.
When a shift to 4WD Auto, 4WD High, or 4WD Low is requested, the Transfer Case Control Module engages the front axle by grounding the front axle actuator control circuit through a current limiting driver.
This Diagnostic Trouble Code (DTC) will be set when a short to ground, short to voltage, or open circuit is detected.
