P0C5D 2016 Chevrolet Silverado Code - Drive Motor Position Sensor Circuit 2 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 P0C5D 2016 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 2 reference voltage is greater than 4.9 V.

3. What causes the P0C5D code to appear on a 2016 Chevrolet Silverado?
Causes can include a malfunctioning drive motor position sensor, damaged wiring or connectors in the sensor circuit, or a fault in the powertrain control module (PCM).
4. Can you drive a 2016 Chevrolet Silverado with a P0C5D code?
It is not recommended to drive with this code active, as it could result in reduced performance or further damage to the hybrid or electric drive system.
5. How is the P0C5D code diagnosed on a 2016 Chevrolet Silverado?
A technician will use a scan tool to confirm the code, inspect the wiring and connectors for damage or corrosion, and test the drive motor position sensor for proper operation.
6. How do you fix the P0C5D code on a 2016 Chevrolet Silverado?
Repairs may involve replacing the drive motor position sensor, repairing damaged wiring or connectors, or reprogramming or replacing the PCM if it is faulty.
7. What tools are needed to diagnose and fix the P0C5D code?
You’ll need an OBDII scanner, a multimeter for testing electrical connections, and possibly a specialty tool to remove and replace the drive motor position sensor.
8. Is the P0C5D code covered under warranty for a 2016 Chevrolet Silverado?
Depending on the vehicle's age and mileage, the issue may be covered under the powertrain or hybrid system warranty. Check with your dealer for details.
9. What happens if you ignore the P0C5D code on a 2016 Chevrolet Silverado?
Ignoring this code can lead to reduced vehicle performance, further damage to the hybrid or electric drive system, and potentially higher repair costs.
10. Can a low battery voltage cause the P0C5D code on a 2016 Chevrolet Silverado?
While the code specifically refers to high voltage, issues with the battery or charging system could indirectly affect the sensor circuit and should be inspected.
