P0C53 2017 Chevrolet Silverado Code - Drive Motor Position Sensor Circuit 1 High Voltage
Quick Answer
The generator control module also called the starter/generator control module, is comprised of the following three control modules: the hybrid/EV powertrain control module 1, 14 V power module, and the drive motor control module. Common causes include Faulty Starter/Generator, Starter/Generator harness is open or shorted, Starter/Generator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0C53 2017 Chevrolet Silverado Description
The generator control module monitors the angular position, speed, and direction of the starter generator rotor based upon the signals of the resolver-type motor position sensor. The position sensor contains a drive coil, two driven coils, and an irregular-shaped metallic rotor. The metallic rotor is mechanically attached to the shaft of the starter generator.
At ignition ON, an AC voltage, 10 kHz excitation signal is output to the drive coil. The drive coil excitation signal creates a magnetic field surrounding the two driven coils and the irregular-shaped rotor. The generator control module then monitors the two driven coil circuits for a return signal. The position of the irregular metallic rotor causes the magnetically induced return signals of the driven coils to vary in size and shape. A comparison of the two driven coils signals allows the generator control module to determine the exact position, speed, and direction of the starter generator rotor. The position sensor is a non-serviceable part of the starter generator.
The Diagnostic Trouble Code (DTC) will be set when the Drive Motor Position Sensor Circuit 1 reference voltage is greater than 4.9 V.
